About BoilerReplacementCost.com

Why this site exists

UK boiler replacement information online is dominated by installer-affiliate content sites (Heatable, BoilerCentral, MyJobQuote, Checkatrade, BOXT) whose commercial interest is to funnel readers to a quote form. Their content structure follows that interest: a single long-form "here is how much a boiler costs" article with a quote CTA. The user is not given the prior decision: do I actually need a new boiler, and if so along which of four different paths?

This site takes a different shape. It assumes the reader is at the start of the decision, not the end. We map the four options (repair, like-for-like swap, conversion, heat-pump alternative) with calibrated UK 2026 cost ranges at each branch, then go deep on the most-likely scenarios for UK homes. There is no quote form, no booking commission, no affiliate funnel. The site is the editorial guide; the user's next step is finding a Gas Safe registered engineer independently via gassaferegister.co.uk.

What this site covers

Editorial principles

Methodology in brief

UK boiler unit prices are 2026 RRPs published by each manufacturer, cross-checked against Heatable and BOXT installer-direct pricing and against Which? Best Buy Boilers retail data. Installed cost ranges add typical UK labour + flue + magnetic filter + powerflush + Building Control budget on top of unit price. Regional cost variation is calibrated against Gas Safe engineer labour rate surveys. Grant data is from gov.uk and Ofgem published terms. Running cost figures use Energy Saving Trust 2026 calculations and assume UK average gas usage and unit cost. See methodology for the full source ledger and refresh cadence.
