What Affects a Boiler Engineer’s Price?

Gas Safe registration. By law, anyone working on gas appliances in the UK must be on the Gas Safe Register. That qualification is part of why a boiler engineer costs more than a general plumber for gas work.

Service vs repair. A service is a fixed, predictable cost; a repair depends entirely on the fault and which part has failed.

Boiler brand. On a new install, the boiler unit itself is a big share of the price — premium brands cost more but often carry longer warranties.

Region and out-of-hours. London and the South East run higher, and a no-heat emergency in winter carries a premium call-out.

Frequently Asked Questions

How much does a boiler service cost in the UK?

An annual boiler service typically costs £70–£120. It is worth doing every year — most boiler warranties require an annual service to stay valid, and it catches small faults before they become a winter breakdown.

How much does a new boiler cost installed?

A new combi boiler supplied and fitted typically costs £1,800–£3,500. The exact price depends on the boiler brand and output, whether the flue and pipework need moving, and the condition of the existing system.

How much is a landlord gas safety certificate (CP12)?

A landlord gas safety certificate (CP12) typically costs £60–£120 depending on the number of gas appliances. It is a legal requirement for rented homes in the UK and must be renewed every 12 months by a Gas Safe registered engineer.

How we work out these figures

Figures are typical 2026 UK price ranges, not a single measured GeraHome price. They are compiled from publicly published UK tradesperson rate surveys and standard hourly/day-rate conventions, then expressed as a low–to–high band because real quotes vary with region, job complexity, access, materials, time of day, and whether the trade is independent or an agency. London and the South East typically run 20–40% above the national average; the North, Midlands, Wales and Northern Ireland typically sit below it. Always get an upfront, itemised quote before work begins.

These are typical ranges, not a single GeraHome-measured price. We publish honest bands rather than invent a precise per-city number we do not have.
