The higher price of Worcester Bosch boilers reflects their quality, reliability and variety of features. Usually, Worcester Bosch models begin at around £800 at the cheaper end, rising up to around £2,500 for more expensive models.
In terms of Ideal boilers, you’ll likely be paying £600 - £1,400 for a combi boiler, with some high end models costing upwards of £2,300.

Worcester Bosch vs Ideal: Warranty
Worcester Bosch are renowned for having a guarantee instead of a warranty. What this means is that they provide parts, labour and call-out fees if you experience any issues with your boiler - all at no cost to you (assuming your guarantee is still valid)! These guarantees vary product to product, but there is a Worcester Bosch guarantee length check on their website.
Ideal heating on the other hand offers a warranty, which is a contractual agreement, more like an insurance policy (whilst a guarantee is a promise to ensure reliability). These warranties cover manufacturing issues with appliances, and vary anywhere from 2 - 12 years.
