Frequently Asked Questions
How much does a boiler service cost?
A boiler service typically costs £70 – £150 inc VAT, with £100 – £120 the most common spend across the UK. A full central heating service — covering the whole system rather than the boiler alone — sits in the same £70 – £150 band, and an unvented cylinder service runs £100 – £180 a year.
What is the most expensive heating job?
Boiler replacement: a new combi, supplied and fitted, costs £1,800 – £3,000, a system boiler runs £2,500 – £5,000, and complex installations reach £6,000. Whole-house underfloor heating at £70 – £120 per m² installed also adds up quickly across larger floors.
Why are heating prices higher in London?
Gas engineers' labour rates, travel and parking push London and South East prices roughly 20–30% above the rest of the UK — a boiler repair moves from £150 – £400 to £200 – £500 in the capital.
Does boiler work have to be done by a Gas Safe engineer?
Yes — any work on a gas boiler, fire or pipework is illegal unless the engineer is on the Gas Safe Register, so always check the ID card before work starts. Landlords must also hold a current CP12 gas safety certificate, at £60 – £90 for a boiler plus one appliance, renewed annually.
