Combi Boiler Prices

We’re going to compare gas combi boiler prices in 2018 on over 63 models from all the main manufacturers. We’ll list deals and prices of all new boilers including Worcester Bosch, Viessmann, Vaillant, Potterton, Main, Ideal, Glowworm, Ferroli and Baxi.

The aim of this guide is to help you find the most suitable boiler for your properties size and your budget. We’ve therefore included budget boilers, mid-range boilers and premium boilers on our list. We’ve categorised them into small, medium and large boilers depending on their heat output and hot water flow rates.

We’ve only considered wall hung boilers so floor standing boilers have been excluded. All boilers compared are A-rated and the ‘Best Buys‘ in each category have been scored 10/10. How did we work out this score?

We questioned 3,100 homeowners on how happy they were with the combi boiler brand they have at home. Specifically, we asked questions about the number of breakdowns in the first 5 years of ownership, value for money and ease of use.

Homeowners were asked 3 questions, the answers were weighted in the order shown and the results were compiled:

How many times has your combi boiler broken down in the first 5 years?
Do you think £XXX for your combi boiler is good value?
Do you find your combi boiler and controls easy to use?

Prices are correct as at 13th April 2018.
