What is a Worcester Bosch Boiler?

Worcester Bosch are one of the leading manufacturers of boilers in the UK. They have been providing boilers for over half a century. Innovative and stylish, their boilers are ahead of the game in technology and look sleek and modern.

They win the Which? Award every year and, above all, they are reliable and provide fantastic aftercare. With a full range to suit all homes and budgets, you can’t go wrong.  For the 12th year running they have won Which? Best Buy for their oil and gas boilers and the new Worcester Greenstar 2000 and 4000 range have been awarded the QuietMark status.

Arguably, Worcester boilers are some of the best boilers on the market. Their product is one you can trust in your home.

We install Worcester boilers every week of the year and know this product inside out. We’re here to help you make the best choice of boiler for your home and ensure you’re buying a quality product and installation.

What is the lifespan of a Worcester Boiler?

Worcester Bosch boilers typically last between 12-15 years.

A Worcester boiler should last the full 15 years and perform well the whole time, depending on whether you maintain it or not. Annual boiler maintenance is key to ensuring a healthy boiler and prolonging its lifespan.

Why choose a Worcester Bosch Boiler?

There are plenty of reasons why Worcester Bosch is one of the leading boiler brands and why they work for so many people.

  • Peace of Mind

We install a lot of these boilers year on year, so we need to know that the product is reliable for our customers. You can be confident that these boilers will provide you with peace of mind that heating and hot water will be available throughout the year.

Even with a boiler breakdown, our team is available to help.

  • Highly Rated

Worcester Bosch boilers use the latest technology – the new Style boiler is touch screen and available in black or white. They have won Which? Best Buy for 12 years running and were recently awarded QuietMark for their 2000 and 4000 models of boiler.

  • Energy Efficient

The Worcester Bosch range is energy efficient, which will reduce your energy bills in the long run and is far better for the environment.



Worcester Bosch supplies a significantly large range of boiler types and systems.

They stock the full range of boiler systems:

  • Combi
  • System
  • Regular

They also offer the main boiler types:

  • Gas
  • LPG
  • Oil

Worcester can cater to most boiler/household requirements. They have a compact series for smaller homes, wall-mounted boilers for space saving, a highflow range for higher heating demands and much more.

Their Greenstar range is much more energy efficient than previous models and are available for all boiler systems. The Worcester Greenstar 2000 and 4000 range have also been awarded the QuietMark status.

There are a lot of boiler types to navigate through; that’s why it is so useful to contact our team and allow us to guide you through this process and ensure that the most suitable boiler is chosen for you.

What are the benefits of having a Worcester Bosch Boiler installed by a Worcester accredited installer?

Lacey Plumbing & Heating have been Worcester Accredited Installers since 2012. We are therefore able to offer exclusive extended guarantees on all Worcester boilers up to a maximum of 12 years.

This is a manufacturer’s ‘parts and labour’ guarantee, subject to the boiler having an annual service. This means that if you have a breakdown during the guarantee period, Worcester Bosch will send one of their engineers to provide parts and labour to repair your boiler.

All you need to do is have your boiler serviced by a Gas Safe engineer, such as ourselves, every year.  A standard Worcester Bosch guarantee is only 7 years, so a WAI can extend your guarantee to up to 12 years for free.

The guarantee on the boiler stays with the house. So, if you move, having a Worcester boiler installed with a long guarantee in place is a great selling point.


How long does it take to install a Worcester Bosch Boiler?

It typically takes around 1-3 days to install a Worcester Boiler, depending on a few factors relating to boiler type and conditions in the home. A home survey will be required beforehand – this may add to the time it takes to complete the installation.

The main factors that will affect installation time are:

  • Whether the boiler replacement is like-for-like
  • How much work it would take to remove the old boiler
  • What the old and new systems are (a system to combi conversion, for example, would take far longer than a straight combi swap)
  • Whether relocation is needed, as existing pipework may need to be changed
  • Whether smart controls will need to be installed

How much is a new Worcester Bosch Boiler installation?

When considering buying a new boiler, we would prefer to attend your home to carry out an in-depth survey. This ensures that we get the correct boiler for your requirements and heating system.

This could save you money as often, when a site survey is not carried out, the boiler size is based on guess-work and you may end up buying a boiler that is too big for your requirements.

There are a number of different factors which contribute to the cost of a new boiler. The main areas are:

  • Brand
  • Positioning
  • Type of boiler system

2022 Guide To Buying A New Boiler

Buying a new boiler often comes with a lot of stress. Being without heating and hot water can be tough, particularly when in the colder months.

It can be difficult to decide which boiler is right for your home or business in order to help increase energy efficiency and reduce costs.

At Lacey Plumbing & Heating, we are dedicated to helping our customers choose the right boiler for their home or office and to install their new boiler in a timely and professional manner.

Our experienced heating team are on hand to assess your current heating system and provide expert advice on which boiler is right for you.

Our 2022 guide to buying a new boiler will help you to run through the steps you should take before making a purchase.

Why Should I Buy A New Boiler

There are 2 main reasons why you might want to buy a new boiler:

  1. Your current boiler is broken beyond repair
  2. Your current boiler is losing efficiency and costing you more than it should do

If you need a new boiler, you’ll want to source one that is effective, well suited to your home and general usage and will save you money in the long run.

A boiler will begin to decrease in efficiency after around 8-9 years, likely leading to your heating costs increasing. After all this time, your boiler will also be more prone to faults and you’ll have to factor in regular, costly repairs to keep you warm throughout the year.

Buying a new boiler allows you to benefit from lower heating costs, whilst also preventing persistent, high-cost repairs. It has never been a more important time to get expert advice on buying the right boiler with energy prices increasing.

You want to ensure that you’re making the right choice, which will save you money.

When Is The Best Time To Buy Or Replace A Boiler?

This may be obvious, but the best time to buy a new boiler and replace an old one is in the warmer, summer months.

This is because you may have to go a few days without any heating or hot water when your boiler is changed. This can be even longer if your boiler breaks suddenly and you’re searching for the right installer and new boiler.

It’ll have less of an impact in the months where your home is already relatively warm.

Often however, people do consider buying a new boiler in the colder months as lower boiler efficiencies become more noticeable.

No matter what time of year, our Gas Safe heating engineers can facilitate your needs and get you up and running with a brand new boiler. We can sometimes even fit boilers next-day if the need arises.

Which Type Of Boiler Should I Buy?

This is the area that will require the most thought. Choosing the right type of boiler for your home is crucial to improving efficiencies and lowering costs.

We’ll run through the different types of boilers that you can have in your home and help to guide you towards the most suitable one.

Not only will you have to consider what type of boiler is right for your heating and hot water requirements, you’ll need to put some thought into what brand of boiler you’d like to have installed.

Worcester Bosch, Ideal and Baxi – these are just 3 of the leading brands of modern boilers. Don’t worry though, we can help you choose the most suitable boiler based on your needs, home and budget.

Combi Boiler

Combi boilers are typically the most popular in the UK. They are currently the most modern and compact form of boiler for your heating system. They are therefore a common choice amongst buyers and installers.

If you are looking for:

  • On demand hot water;
  • Instant heating;
  • A smaller system with no need for tanks or cylinders;
  • A system that will power only 1-2 bathrooms;

… then a combi boiler is your best option.


System Boiler

A system boiler is the option those with a larger home typically choose. It can handle high demand if you have 2 or more bathrooms due to it storing hot water in a cylinder.

You may have to wait at times for your hot water cylinder to fill however, and of course you’ll need the storage space for the cylinder and tank too.


Regular Boiler

A regular boiler, often called the conventional boiler, is commonly found in older properties. This system isn’t often used anymore due to the need for extensive pipework to connect to the mains.

Still unsure on which boiler is right for your home? Get in touch to speak with an expert

What Checks Should You Do When Buying A New Boiler

When buying a new boiler and paying for a new installation, you’ll want to be certain that you’re getting the best deal and the best service. Once you’ve set your budget and have an idea of which boiler you want for your home, there are a few other checks that you should do:


Check The Manufacturer Warranty

Your chosen boiler will have warranty from its manufacturer; this does mean however, that the length and terms of this will vary between brands. It is worth checking what guarantee you have with your chosen boiler manufacturer and registering with them asap to avoid losing out.

For example:

Worcester Bosch offers a 12 years boiler guarantee when fitted by a Worcester Accredited Installer, like the team at Lacey Plumbing & Heating.

Ideal offers a 12 years boiler warranty when installed by an Ideal Max Accredited Installer such as ourselves.

Baxi offer 10 years boiler warranty.


Check The Certification And Reviews Of Your Boiler Engineers

It is so important that you check that your boiler engineer is fully accredited and knowledgeable on installing boilers. Luckily, our heating engineers at Lacey Plumbing & Heating are experienced and have installed all types of boiler systems and brands.

You should check that your boiler engineers are:

  • Gas Safe registered (they should have a Gas Safe ID card to prove this)
  • Experienced in installing your chosen brand of boiler

How Much Does A New Boiler Cost To Buy And Install?

Buying a new boiler and having it installed will vary hugely in cost. You’ll need to factor in these elements when considering costs:

  • The type of boiler you want;
  • Whether this system will require extensive pipework;
  • How easily accessible your home is for boiler installation (e.g. transporting and installing a large tank);
  • How large the heating system will be (system boiler installation is typically more expensive);
  • Whether any old equipment will need to be removed and disposed of.

Don’t worry too much about the above however; at Lacey Plumbing & Heating, we will talk you through your best options whilst keeping your budget in mind. We also offer new boiler pay monthly finance options, so you can pay monthly for your boiler installation which is often much more manageable for people.

There are, however, 5 main issues that our heating engineers typically hear about and deal with on a regular basis.

Our top 5 most common boiler problems are:

  1. Boiler is leaking
  2. Boiler pressure is too high or too low
  3. Boiler is noisy
  4. Pilot light has gone off
  5. No heating or hot water

Top 5 boiler issues and how to fix them

Boiler is leaking

Boiler leaks are often superficial and caused by a small hole or crack in the pipework. Although this is still an inconvenience and a problem that’ll need fixing, it isn’t usually a significant worry for people.

Whether the leak is small or large, you still need to pay attention to it. A leak could be far more serious and could indicate:

  • Corrosion to internal components
  • A significant break in pipework
  • Broken seals
  • Faulty installation
  • Pressure issues

These problems can lead to a full boiler breakdown and you’ll need a complete boiler repair or possibly a boiler replacement, so it’s best to get a qualified heating engineer to take a look as soon as possible.

Pressure issues are something that can potentially be fixed at home – we’ll discuss how to deal with boiler pressure next.


Boiler pressure is too high or too low

Boiler pressure trouble is extremely common and often only requires simple tweaking, but it’s always best to consult a professional if you’re unsure of what to do. Safety always takes priority!

We’ve actually written a complete guide to boiler pressure that goes into depth about how to diagnose and fix both low and high boiler pressure, so go check it out for more information.

In a nutshell, you’ll need to check your boiler pressure on either:

  • A dial
  • A hydraulic pressure gauge
  • A digital display

Ideally, it should be showing at 1.5 bars. If it’s too high, you may need to bleed your radiators. If it’s too low, you may have to open your filling loop and top up your boiler with cold water to increase pressure.

If it’s really high and water is leaking outside, then you will more than likely need help from one of our heating engineers as this can sometimes be caused by a part that has failed on the boiler and it’ll require our help to fix it.

If you aren’t confident in fixing pressure issues, get a professional in to help.


Boiler is noisy

Boilers make a lot of noise, but it’s often easy to tell when a noise isn’t quite right. Most noisy faults are described as gurgling, vibrating, whistling or banging. If you’re experiencing this, you’ll likely need a visit from an engineer.

A buildup of limescale, usually on the heat exchanger, creates a whistling sound known as ‘kettling’. This can be fixed by an engineer cleaning out the system and removing limescale.

Other noises could be caused by air in the system (which may be fixed by bleeding the radiators), frozen pipes or a faulty pump. Either way, a heating engineer will be able to diagnose and fix the problem.


Pilot light has gone off

This issue is common amongst those who have an older boiler and heating system installed. Non-electronic ignitions can be blown out by a draft getting into the system or by faulty internal components.

Even if the problem is simple to fix, the affected area is still heavily linked to gas and will therefore require a Gas Safe Engineer to diagnose and repair the issue in a safe and professional manner.


No heating or no hot water

Last but certainly not least, 1000’s of people every year deal with having no heating or hot water at some point. It happens, and it can often rectify itself without intervention. Even so, having no hot water or heating, particularly in winter, can be troubling.

The best thing you can do is act quickly. Being without heating or hot water can cause real issues in the home, so it’s best to call a heating engineer to diagnose and fix the problem as soon as possible.

There are so many reasons why you would experience no heating or hot water. It could be:

  • A thermostat issue
  • Incorrect radiator settings
  • Faulty boiler settings
  • Faulty diverter valve
  • Broken internal component

There are so many other reasons that could be causing you issues – booking a boiler repair is always your best option.

Can I fix my boiler myself?

Now, you may be wondering, can I fix these issues myself? The chances are, you’ll need a qualified heating engineer to help diagnose and fix the issue. Working with gas and pipework can be extremely dangerous and isn’t worth the risk of causing a more serious, costly problem.

Our team of professional heating engineers are available to diagnose boiler problems and repair issues in a timely manner. In the event that your boiler can’t be fixed, we can work with you to find the best solution – this may be you taking advantage of our boiler installation payment plan and future boiler servicing plans.

What to check before calling a boiler engineer

As stated above, it probably isn’t wise to mess with your boiler too much when you encounter a problem. There are, however, a few minor checks you could make to ensure that your boiler actually has a problem that you are unable to fix.

Here are some small checks you can do before getting in touch with our professionals:

  • Check the power supply and assess whether a fuse has tripped and can be reset. We have experienced times where the boiler has been switched off by accident!
  • Check your thermostat and heating controls to see if they are working and if any settings have been accidentally changed. Have the batteries been changed in your heating control recently?
  • Reset your unit – this is sometimes a quick and simple fix, so always worth a try first. Sometimes the control can lose its radio frequency connection. Always refer to the manufacturer’s instructions for common fault finding.

If you are still experiencing issues, give us a call and we’ll be happy to help.


How Lacey Plumbing & Heating can help

Our team is well equipped to diagnose a wide range of boiler problems and make the necessary repairs to get your heating system back up and running as soon as possible.

No matter how significant or minor your boiler problem may seem, we can help provide you with peace of mind knowing that your boiler can either be fixed, or that we can offer cost-effective, simple boiler replacement plans to get you where you need to be.

Our office team are happy to talk through the issues that you have in order to assess whether or not you need an engineer visit. Please give us a call with your issue and we’ll try our best to help.

Why Boiler Servicing Is So Important

We can’t stress enough how important regular boiler servicing and maintenance really is. We attend repairs that could have been avoided through yearly servicing all too often. Annual boiler servicing doesn’t just lessen your chances of experiencing boiler damage, it also ensures that your boiler is running efficiently, keeps your running costs low and most importantly, guarantees that your boiler is safe to use in your home.

Get a boiler service quote now


It is important to keep in mind that a boiler service aims to confirm that your boiler is performing as well as it should, is safe to use and is up to date on all regulations. If there is a fault found, you will be able to book in a separate boiler repair service as soon as possible or, if the boiler is under warranty, our engineers can advise a manufacturer’s call out.

During your boiler service, our experienced Gas Safe engineers will:

  • Check that your boiler is operating correctly, that the gas pressure is correct and that you are happy with its current performance.
  • Check the overall condition of the boiler, looking for any signs of corrosion or leaking.
  • Check that the ventilation requirements are up to standard.
  • Clean where necessary, such as the heating system filter, and check that the boiler flue is clear and safe.
  • Perform a Gas Tightness test to check that your property is Gas Safe.
  • Issue you with a Boiler Service Certificate.

Once you have received your certificate to state that your boiler is working correctly, is safe and is meeting current standards and your own requirements, our office team will ensure your reminder is set for next year and will provide you with advice on our boiler service plans.

If any problems are detected, we can work with you to book in a boiler repair or call out the manufacturer. Whatever happens, we’ll ensure your boiler is up and running to standards as soon as possible.



Boiler servicing is a complex process that should be completed thoroughly with due care and attention – our heating engineers however, are experienced and efficient and can complete boiler services in 45 minutes to 1 hour.

How often should a boiler be serviced?

We get asked this question a lot, and we always give an honest answer to our customers. Annual boiler servicing should, in most cases, be more than sufficient if you want to keep your boiler performing at its best and keep the usage of it safe for you and your family.

Our boiler service plans do include a pay monthly option which allows for your boiler service to be paid in smaller, more manageable instalments. It also provides extra checks on your heating system above what we would do on a standard boiler service.

If you notice any issues with your boiler before or after your service, please let us know and our team can advise you on the best remedy that’s available for you.


When is the best time to book a Boiler Service?

You need to have your boiler serviced every year, on or around the anniversary of its installation. However, it is best to try and have it carried out before winter due to the extra pressure it will be under during this time.

It also makes sense to book a service during the spring to autumn months because of the extra workload for heating engineers during the Winter. They will unfortunately have to prioritise boiler breakdowns and replacements at this time, so scheduling your work during the summer is much easier.

Ready to book your annual boiler service? Get in touch

Why should you get your boiler serviced?

A lot of people struggle to understand why boiler servicing is important and see it as an unnecessary, additional cost. We’re here to help people see how important boiler servicing really is and how it often helps people save a lot of money.


Keep your warranty valid

A lot of boiler manufacturers require you to have your boiler serviced annually in order to keep your warranty with them valid. If you cannot provide documentation to prove that you have had your boiler serviced annually, most boiler brands are within their rights to void your warranty and refuse to pay out for any repairs should you need one.

Our small, monthly payment plan allows you peace of mind knowing that your boiler service is planned in and that you can maintain a secure warranty with your boiler manufacturer.Some home insurance policies also insist that you have your boiler serviced annually, so have a read of the small print.


Maintain boiler efficiency

Having our expert engineers inspect your boiler on an annual basis ensures that your boiler is working efficiently and fulfilling requirements. Regular maintenance and cleaning allows you to utilise the full benefits of your heating system and keeps costs down.


Reduce your heating costs

If your boiler has a clogged filter, blocked flue or even a minor leak, it’ll have to work 10 times harder just to perform at a minimal level. When your boiler has to use more energy, your heating bills will naturally increase.

Having our heating engineers inspect and clean your boiler annually allows the boiler to run at its optimum level with no additional effort, therefore keeping costs down and performance high.

Not only this, but if our engineers suspect a potential issue, you can have this repaired before it becomes a major problem. The cost of repairing a small leak, for example, is far less than forking out for a full boiler repair, burst pipe replacement and the replacement of water damaged flooring and goods!


Ensure complete boiler safety

The number one priority for all households with a boiler is ensuring that they are safe. Our boiler services check every element of your boiler and heating system to be certain that it is safe to use.

It is never worth the risk of allowing an unsafe boiler in your home, so speak to our team today to find out which service package would suit you best.

What happens if a boiler is not serviced?

You are not legally under an obligation to have your boiler serviced annually. You may however, lose any guarantee you have with your boiler manufacturer and your warranty will be void. You may run the risk of using an unsafe boiler, as boilers sometimes present no obvious signs of damage, leakage or blockage. You also increase your chances of having a boiler breakdown.

Servicing ensures that a boiler is cleaned, is safe and if there are signs of any parts deteriorating, these can be highlighted before a breakdown happens. Allowing our boiler engineers to thoroughly inspect your boiler yearly can prevent larger, potentially dangerous issues from happening over the course of the year, costing you far more than the service itself and putting your home and its residents at risk.

FAQs about Boiler Servicing

We understand that you may have a lot of questions about boiler servicing and how we carry out this service. If we haven’t answered your question by the end of this article, and neither has our boiler servicing page, please get in touch.


Is it a legal requirement to have your boiler serviced every year?

If you are a landlord, you are legally required to have your gas appliances checked  annually in your properties with tenants in. You are not required to have an annual boiler service, but we do advise this to ensure you avoid boiler breakdowns and unhappy tenants.

If you own your own home, you are under no legal obligation to have your boiler serviced. We would always recommend that you do get your boiler serviced yearly however – if you need more convincing, perhaps read over our above points again! Need more? Just give us a call and we’ll be happy to chat you through the benefits.


Which boiler brands do you service?

We service most of the common boiler brands, such Worcester Bosch, Baxi and Ideal. Simply let us know what brand of boiler you have and we can advise you on whether our engineers can service it or not.

We often service older style boilers, so don’t hesitate to get in touch even if your boiler is a different brand or a conventional, older boiler.


Can I pay for my Boiler Service by monthly payment?

Yes, at Lacey Plumbing & Heating, we offer a convenient and simple way for you to pay for your boiler service through our Boiler Service Plans. We aim to keep payments low and remind you when your next service is due, taking all of the pressure away from you.

Our bespoke boiler service packages offer an affordable way for you to ensure that your boiler is inspected and cleaned frequently, helping to reduce potential problems before they turn into larger, more costly and dangerous issues.

Combi Boiler vs Conventional Boiler: Should you convert?

If you currently have a conventional boiler, it’s likely that you have thought about how a more modern, more efficient combi boiler could benefit your household.

Get A Boiler Service Quote Now

A lot of larger homes require a conventional boiler, but the average UK home can easily be powered by a combi boiler, providing cost-effective  instant hot water.. Learn more about whether you should convert from a conventional boiler to a combi boiler in our detailed guide.

What is a Combi Boiler?

A combination or ‘combi’ boiler acts as both a water heater and a central heating system in one compact unit. The water you use around your home is heated directly from the mains when a tap is turned on, without the need for a bulky water storage tank.

A combi boiler is a great space saver and fits well into smaller homes or in homes with no additional storage space for a water cylinder. The water is also powered through the mains, so you can have high water pressure in important areas such as the shower.

A combi boiler can be either gas or electric, although the most common combi boiler uses either natural gas or LPG.

What is a Conventional Boiler?

A conventional boiler, also known as a regular boiler, has a separate hot water cylinder and cold water storage tank. The cylinder system will provide hot water for the central heating system and the boiler will be fed cold water from the tank to heat for daily use in taps and showers.

The cold water storage tank is usually placed as high up as possible to help increase the water pressure, so is often found in the attic. The hot water storage cylinder is usually stored in an airing cupboard.

If a lot of hot water is used in a home, often when the home is on the larger side, a conventional boiler usually works best. In this case, you need to consider the time taken to reheat your hot water cylinder.


What is the difference between a Combi Boiler and a Conventional Boiler?

The main difference between a combi boiler and a conventional boiler is that a combi boiler provides both heat and hot water through one unit and a conventional boiler has a separate hot water cylinder and cold water storage tank.

With a combi boiler, you have access to unlimited hot water and heating but with a conventional boiler, you’d need to wait for water to re-heat once you use it all. A regular boiler will be able to deal with high water usage better than a combi boiler would and is usually better for properties with more than two bathrooms or where there is low water pressure.

Can you replace a Conventional Boiler with a Combi Boiler?

Yes, you can replace a conventional boiler with a combi boiler. Often, homeowners want to modernise their heating systems to save space and costs and increase efficiency.


What is involved in a Combi Boiler upgrade?

The process of an upgrade to a combi boiler can vary hugely depending on your current heating system. Factors involved in this process include:

  • The removal of the old hot water cylinder
  • The removal of the old cold water storage tank
  • Draining the water from the old system and pipework
  • Removing the old boiler
  • Upgrading the gas run
  • Converting the full system to a combi system
  • Installing the new combi boiler
  • Configuring the new thermostat controls where applicable

Options that may alter the process include:

  • Whether the boiler is being moved to a new location
  • Whether a new hole for the flue needs to be drilled
  • Whether new heating controls need to be installed


Is it a big job to change a Conventional Boiler to a Combi Boiler?

In general, changing a conventional boiler to a combi boiler takes around 2 days as it’s a more complex heating job and requires a lot of expert installation, intricate structural pipework changes and the removal of large equipment.

Despite the fact that this process is a relatively large one when compared to other heating jobs, it’s a process that we are very familiar with and are well equipped to do in a timely, efficient manner. We regularly carry out system conversions.

Should I convert to a Combi Boiler?

There are a few factors that you should consider when thinking about upgrading your heating system. One of the main things to take into consideration is the size of your home. Combi boilers come in a range of sizes and capacities to suit most average homes with 1-2 bathrooms.

Even if you have more bathrooms, use a lot of hot water or have a lot of radiators, there is still likely to be a suitable combi boiler for you. Combi boilers in general are more efficient, cost-saving and space-saving, so it is well worth seriously considering the upgrade.

Let’s take a look at some of the pros and cons of both the combi boiler and the conventional boiler.

Pros & Cons of a Combi Boiler

For the average small to medium sized home, the combi boiler is a great option.

  • Efficient: Combi boilers provide hot water on demand as opposed to heating then keeping a cylinder of water constantly hot, making it far more efficient.
  • Energy-saving: Having hot water on demand means that less energy is used to heat that small amount each time.
  • Space-saving: Combi boilers consist of just one unit – the standard sized boiler can fit into most sized kitchens and can be concealed behind a cupboard.
  • Cost-effective: Heating water on demand uses less energy and therefore, helps to keep costs down.
  • Easier to Repair: Spare parts are often easier to source for more modern combi boilers, making boiler repair easier and quicker.

A combi boiler however:

  • Isn’t suitable for larger homes that use a significant amount of hot water;
  • Isn’t suitable for homes that have weak mains water pressure.


Pros & Cons of a Conventional Boiler

For the larger home, or home that has a significantly high demand for hot water and heating, a conventional boiler will work more effectively.

  • Meets high demand: The conventional boiler can supply multiple areas of the home with hot water simultaneously, keeping up with high demand for hot water.
  • Well suited to larger homes: If a larger home already has a conventional boiler system installed, it is sometimes best to keep this system in place rather than replacing it. This is because the system is better suited to the size of the home and will be easier and cheaper to maintain.

A conventional boiler however:

  • Requires a lot of storage and installation space;
  • Will mean that you may have to wait for water to heat before having access to it (if you use up all the heated water in the cylinder and still require more);
  • Requires a well insulated space to keep water hot, otherwise heat will be lost.
  • There are a lot more components and controls to maintain and a leak from the tank can cause significant damage.


Costs of a Combi Boiler vs a Conventional Boiler

The cost to convert from a conventional to combi would be around £3000 to £4000 – this is when you’re installing a reputable brand of boiler, such as Worcester Bosch.

A good brand of boiler will come with a 10 to 12 year warranty. Although the cost is front-heavy, you will reap the benefits in the long run with a more efficient heating system and boiler which will lower energy bills over time.

Understanding Boiler Pressure: The Complete Guide

Our complete guide runs through everything you need to know about boiler pressure. We can provide clear instructions for diagnosing and fixing low or high boiler pressure, or alternatively, our heating engineers are ready to help you should you require our assistance.



Boiler pressure, measured by a pressure gauge inside or underneath a boiler, maintains effective water flow around the home and ensures that hot water can flow through the entire heating system.

Your heating system may not work correctly if you are experiencing boiler pressure issues. Too low and hot water may not reach all areas of the heating system. Too high and the system may fail due to overload. Many of these problems can be diagnosed and fixed with relative ease, but sometimes an engineer is required.


Pro Tips

  • Don’t confuse boiler pressure with water pressure!
  • Boiler pressure is the pressure of the hot water in your system.
  • Water pressure is how fast the water comes out of your shower and taps.


Why is boiler pressure important?

Your heating system is pressurised and relies on pressure stability to move water around your home efficiently.

Your boiler heats cold water and pumps this through the pipework in your home. It is important that the right pressure level is maintained in order for your heating system to compensate for pipes expanding and contracting as water heats and cools.


How do I check my boiler pressure?

So, you’ve read and understood how important boiler pressure is for your heating system, particularly in those bitter winter months! Now it’s time to diagnose the issue at hand.

Modern, popular combi boilers will have a built-in pressure gauge for easy reading. Your boiler pressure will more than likely be displayed on one of the following:

  • A dial
  • A hydraulic pressure gauge
  • A digital display

One of these modes of measurement should simply display your boiler pressure and alert you if any problems are present.

Boiler pressure will naturally fluctuate as the heating is used and water subsequently heats and cools. The pressure should stabilise itself once the system is switched off, so don’t worry if you see changes like these occurring.

What pressure should my boiler be?

Normal boiler pressure should be around 1.5 bars as standard. Your pressure gauge should indicate when there is an issue. This is usually shown by:

  • A needle on a dial pointing to a red, amber or green zone.
  • A digital gauge displaying an error message, code or symbol.

Low boiler pressure

You may be able to fix low boiler pressure yourself. Firstly, run through these 2 initial steps:

  1. Check the pressure gauge to be certain that your boiler pressure is low
  2. Consult your boiler manufacturer manual if you have it (it may inform you of certain checks you need to make or steps you need to take that are brand specific)

Signs and common causes of low boiler pressure

Your boiler pressure is likely to be too low if:

  • The pressure gauge reads low
  • You have no heating or hot water
  • Your radiators aren’t heating up correctly

Common causes of low boiler pressure include:

  • Boiler has naturally lost pressure over time
  • Boiler is leaking
  • Pipe/pipes are leaking
  • Radiator/s needs bleeding

How to increase boiler pressure

Great news! It’s likely that you can increase your boiler pressure yourself in just a few simple steps.

*Tip: Increasing boiler pressure is sometimes referred to as ‘re-pressurising your boiler’.

If your boiler pressure is low, follow these steps:

  1. Turn off your boiler.
  2. Locate your boiler’s filling loop. This is usually directly underneath the boiler and will have either:a) A keyless filling link which is two water pipes with valves on the ends, linked by a small braided hose; b) A keyed filling link which is internally located, meaning that you will need to consult your boiler’s manual to find it, orc) Standard external filling loop which looks like a silver braided hose.
  3. Open the valves by turning them to allow cold water to fill the boiler. You should be able to hear the water running and see the pressure gauge rising.
  4. Wait for the pressure gauge to display a normal range and shut off the valves at around 1.5 bars. You may have to press reset on some boilers.
  5. If the boiler pressure maintains normal levels and no water is leaking (that you can clearly see), you can now turn your boiler back on.
  6. Allow the boiler to run and then cool down again. Re-check the pressure to ensure that it hasn’t dropped significantly.
  7. Grab a lovely hot shower or cosy up with the radiators on! You’re all set.

You shouldn’t have to worry about increasing your boiler pressure all that often. If your pressure drops more than twice a year, consider thoroughly checking for leaks.

If you do find a leak, or continue experiencing low pressure, book an engineer visit  as soon as possible.


Is low boiler pressure dangerous?

No, low boiler pressure isn’t dangerous.

Low boiler pressure may indicate a leak, which on a large scale may be damaging, but these leaks are far more likely to be minor and can be easily repaired. Just be careful of water leaking near any wires or electrical connections.

High boiler pressure

High boiler pressure is a slightly more difficult issue to fix on your own, though through some research on our blog beforehand, you may be able to repair it yourself. Run through the 2 initial steps again first:

  1. Check the pressure gauge to be certain that your boiler pressure is high
  2. Consult your boiler manufacturer manual if you have it

Signs and common causes oh high boiler pressure

Your boiler pressure is likely to be too high if:

  • The pressure gauge reads high or is in the red zone
  • Your boiler is making a banging noise
  • A small copper directly outside your property from the boiler may be discharging water

Common causes of high boiler pressure include:

  • Too much water was added to the boiler in a previous attempt to correct low boiler pressure
  • Valves on the filling loop are open or broken, allowing water to continuously flow in
  • The expansion vessel may have failed on your boiler

How to reduce boiler pressure

Firstly, you’ll need to diagnose the specific issue that is causing you to have high boiler pressure. By running through some simple steps, you can usually figure out what’s causing the problem and work to resolve it.

Check the fill valves

  1. Turn off the boiler and let it cool if needs be.
  2. Check that your filling loop valves, or keyed filler, are shut tight and fully closed.
  3. Check if your pressure gauge has returned to displaying a normal reading. If your pressure is still too high, move on to the next possible issue.

Bleed your radiators

If the above has failed to work, you may need to bleed your radiators. You can do this yourself, but take care in doing so as it is easy to make mistakes. If you run into an issue or are uncertain about this task, contact a professional such as ourselves.

  1. Turn off the boiler and let the system cool down.
  2. Use a radiator key to gently open each valve on your radiators, one at a time.
  3. Release any trapped air in your radiators in its entirety.
  4. Repeat this for each radiator, then re-check your pressure gauge. If it is still too high, you may need to repeat the bleeding process one by one, ensuring that you go back and check the pressure gauge after each bleed.
  5. Continue checking the gauge until it reads normal again, between 1 and 2 bars or in the green zone. If your boiler pressure ends up too low, repeat the above procedure on increasing pressure.
  6. Take a lovely hot bubble bath! You’ve earned it.

If your boiler pressure is still too high, you should arrange a boiler repair and have a Gas Safe Registered engineer diagnose and fix the problem.

Is high boiler pressure dangerous?

No, high boiler pressure isn’t typically dangerous.

A boiler pressure relief valve in your boiler will protect the system, preventing significant damage by allowing water to escape when pressure is too high. Your system may also shut itself off for safety if it detects seriously high pressure. You may also see water discharging to outside which is a safety feature.

As a Worcester Approved Installer we have made a pledge and signed up to their ‘Safe In Your Home’ Commitment. This means we are following best practice safety measures in order to carry out installations and maintenance work.

By following the practical guidance set out by the UK Government, you, our customers, will remain protected while plumbing and heating work is completed.

This way of working begins with following the current government guidelines which is currently – STAY ALERT. This isn’t all and we have updated our processes accordingly to consider all potential risks to our customers and team.

All customers will be asked if anyone if the house has any symptoms of Covid-19 or if they are vulnerable, so we can assess before we go. All customers will have the process of how we are currently working explained to them.

Our engineers will call you from outside your property so that you can open the door for our team. Our engineers will be wearing appropriate PPE as they would at any site. They are not obliged to wear a face mask in a domestic property but we have supplied them if an engineer feels that they would prefer to wear one.

Our engineers will wash their hands on arrival at the property, carry out the work/diagnosis, and then clear up their work area with disinfectant paying particular attention to areas that they might have touched – such as door handles.

If they need to talk to a customer they will either do this outside, at a distance inside or from their mobile phone while the customer is in another room. It’s entirely up to you and what you feel most comfortable doing.

If you are shielding or are still unsure about having engineers in your house, we’re continuing to offer video calls. During a call we can provide contactless advice over the phone if you have any questions about a potential emergency repair, including leaks and breakdowns. And as an added bonus you’ll get face time with the famous Most Wanted Plumbers!

If a video call isn’t an option for you, we’re also here at the end of the phone line and you can email photos to us, so that we can review them in a similar way.

All Lacey Plumbing and Heating Ltd quotations are free, so contact us today on 0161 884 1108.

Unfortunately no matter what time of year it is a boiler can break down, which forces you to think about the cost of trying to repair a boiler compared to the installation of a new one.

This week, one of our customers had to make this exact choice and although the weather is mild right now, the prospect of being without any heating or hot water was concerning.

Even more so at the moment during the Covid-19 Crisis, when we all need a reliable boiler for access to hot water so we can quickly shower after we’ve been to the supermarket or get home after working in a front line or key worker role.  For this particular Lacey’s customer it made sense to have the peace of mind that came with a new boiler installation, rather than risking multiple boiler part changes and heating engineer visits. It was also unlikely to have been cost effective to have a repair carried out, given the age of this customer’s existing boiler.

The installation of choice was a Worcester 8000 Life 30kw system boiler with a Worcester Greenstar system filter and a Gledhill Unvented cylinder. The customer who lives in Unsworth, Bury, already had this type of system set up and opted to stay with the same brand but with modern products.

The benefits of this type of Worcester system is the supply of hot water from the unvented cylinder. For instance, if the central heating side of the system stopped working you would still have hot water and vice versa. Although with a brand new boiler installation it’s unlikely to suffer a breakdown any time soon!

This installation benefitted from a 12 year manufacturer’s guarantee with Worcester Bosch for parts and labour; that’s complete peace of mind until 2032! Since Lacey Plumbing & Heating is a Worcester Accredited Installer we’re part of a network of approved installers who can provide these exclusive guarantees.

We’re chuffed to bits to have another very happy Lacey’s customer who had a quality installation and complete peace of mind for their heating and hot water.

To comply with social distancing we now offer boiler surveys by video call and photographs. We’re also following all government guidelines, by physically distancing ourselves from customers and using the correct PPE. Our team is carrying out thorough hand washing, using sanitizing hand gel and are wearing face masks and gloves. On arrival to all emergency home visits, we call from outside and customers are asked to stay at a safe and suitable distance.

If you’ve suffered a boiler breakdown or are looking to replace your boiler before it breaks down then contact us to discuss how Lacey’s Most Wanted team can help you at this time.

This week we were delighted to be able to restore hot water and heating to one of our amazing frontline staff’s homes. We are currently continuing to provide emergency plumbing repairs and work to homes that need it, so it was great to be at the forefront of this local key-worker’s mind in her time of need.

We carried out a new combination boiler swap for an NHS midwife – her boiler had broken down and it wasn’t cost effective to repair it due to the model of boiler and its age.

The customer needed to be able to shower before and after her long hospital shifts to keep herself and her family as safe as possible during the current crisis. Thankfully our Most Wanted team were able to come to the rescue and sort a fix within less than 24 hours.

Our engineer arrived on site first thing in the morning and the new combination boiler was fitted the same day. Of course we provided a service that adheres to current government social distancing guidelines and as we always do, we cleaned up after ourselves. We left the customer with a fully functioning boiler.

The boiler that we installed was a Worcester 30i combination boiler with a Worcester Greenstar system filter. This brilliant boiler comes with a 10 year guarantee, since Lacey Plumbing and Heating Ltd is a Worcester Accredited Installers.

Following the installation, our office team will register the boiler warranty with Worcester Bosch and the installation with Gas Safe. Given that this customer work was carried out at a rental property, a landlord gas safety certificate was also issued as part of the installation.

We received a follow up message from the customer which we were extremely chuffed to read! The midwife wrote: “I just want to say thank you –  the engineer was a true hero today.” Well to us this is just the job we do and as an NHS worker, she is the true hero!

If you’re looking for a new boiler installation from a friendly team that truly cares then give us a call today – 0161 884 1110. Our office may be closed but we are still here to help and calls are being diverted so we can still chat with you from home.

You can also email us on or complete the ‘contact us’ form right here on the website. We look forward to helping you in the near future.

So what happens if you have an emergency leak or breakdown? Are we still able to attend your property and make necessary repairs? We currently can only attend your house to carry out emergency plumbing, heating or gas work such as no heating or hot water or a major leak of water or gas. To do this will must follow current guidelines on social distancing.

If you need us call us on 0161 884 1109 as normal and someone will be in touch.

Even though things are a little different it doesn’t mean we can’t plan in work for the future for once the lockdown is lifted. We can offer advice over the phone if you have any questions about a potential emergency repair, including leaks and breakdowns.

To do this we are offering video appointments via WhatsApp and providing video quotes. We can video call you at a time and day that’s convenient to you and chat to you about your requirements, see your house and assess any potential issues, with zero risk. We know this is a new way of working for many people but it’s actually really effective and is proving very popular!

If a video call isn’t an option for you, we are still here at the end of the phone line and you can email photos to us so we can review them in a similar way.
