How we write our boiler guides
Each boiler guide starts from the question people actually search for and answers it in the first paragraph. We read the manufacturer or official page for every rule, code or scheme before we write about it, and we link to it so that you can check. Figures such as prices, grant amounts and warranty lengths come from our data and sources, never from memory, and each page carries a review date.
If you are choosing a boiler, start with boiler types and the combi boiler prices page. If you already have quotes, our compare tool and quote checker help you weigh them, and you can get free quotes from Gas Safe installers. Read about us for who writes the guides and how the site is paid for.
