A standard combi-to-combi swap starts at £2,100 including the boiler, parts, and a day's labour. System and regular boiler installs are quoted individually because the pipework and cylinder work varies.

Between £2,100 and £3,500 for most domestic installs, including a quality A-rated boiler, a magnetic filter, and a power flush if needed. The price varies with boiler brand, flue routing, and any system upgrades.
