What is an energy efficient boiler?
Energy efficient boilers are boilers which use less fuel, therefore less energy, than a regular non-efficient boiler. As it uses less fuel, it means it will save you more money on your hot water and heating bills.
What is a good efficiency rating for a boiler?
Boiler efficiency is used to show how well the boiler turns fuel into usable energy, such as heat and hot water.
All boilers now must be condensing, meaning they run on either gas or oil. Because of this, most modern boilers now have very similar efficiency ratings, also known as ERP ratings, ranging from A+++ down to a G.
The higher the score, the more efficient the boiler is, and most modern boilers are highly efficient so will typically have an A+ rating.
As well as the letter graded ratings, boilers have a space heating efficiency rating which comes in the form of a percentage. Modern boilers will have a rating of around 94% to 92%.
What type of boiler is cheapest to run?
Depending on the size of your home, condensing natural gas combi boilers and system boilers are the cheapest to run, which is why they are the most popular boilers across the country.
Electric boilers are on the more expensive side, but you can make your electric boiler cheaper by adding renewable energy in the form of solar panels to your home.
The solar energy can be turned into electricity which is then used to power appliances around your home, including electric boilers.
What is the most energy efficient boiler?
Combi boilers are compact heating systems, meaning you don’t need to fit them with a cylinder. They deliver hot water on demand. They have very quickly become the top heating choice for UK homeowners, making the market competitive.

Energy efficient boiler systems
Condensing boilers are fitted with two internal heat exchangers to ensure that less heat is lost. This means that it uses less energy, and doesn’t have to work as hard.
This means that condensing boilers are far more efficient than non-condensing boiler units. If you have an old non-condensing boiler, upgrading to a new condensing boiler could save you up to £300 on your annual bills.
Most new gas condensing combi boilers come with an energy percentage of 98%. This can decrease over time, but on average the efficiency rating remains higher than conventional boiler systems.
System boilers usually achieve an efficiency of around 90% at optimum conditions.
How energy efficient is my boiler?
As a customer, you don’t need to know all the technical details of how efficient your boiler is. We can advise on the most energy efficient boiler when we survey your current heating system. However, it is worth understanding the basics as it can have a large impact on your annual spendings.
To calculate the boiler efficiency, we need to divide the energy output by the total energy input, multiplied by 100 to get a percentage.
How much can an energy efficient boiler save?
If you upgrade your old boiler to a new energy efficient one, you are likely to save between 20-35% on your gas bills.
This means you could save up to £350 per year by simply changing your boiler to a higher efficiency rated model.
