We started BoilerBlog because we were frustrated by boiler advice that was really just a sales funnel. Every article, calculator, and comparison on this site is written to help you make the best decision for your home — not to earn us a commission.
We don't sell boilers and we don't take referral fees from boiler installers. Our income comes from display advertising, which means our advice stays unbiased.
Boiler advice varies by country. Everything on BoilerBlog is written for the UK — our climate, our grants (ECO4), our Gas Safe requirements, our typical home types.
ECO4 eligibility, boiler prices, and energy tariffs change regularly. We review and update every article at least twice a year so the numbers you read are real.
BoilerBlog was founded in 2024 by a team of UK homeowners who had been through the boiler replacement process and found it needlessly confusing. Most online resources were either too generic, too technical, or quietly trying to sell you something.
We built the resource we wished had existed — starting with a complete cost breakdown, a plain-English guide to ECO4 boiler grants, and a calculator that accounts for realistic UK installation costs based on home type and region.
Today BoilerBlog covers everything from understanding boiler costs and grants to installation, brands, and choosing the right system. If there's a topic we haven't covered yet, let us know.
