How Much Does a Boiler Service Cost in 2026?
A standard boiler service in the UK varies by company and location. AR Heating & Gas charges from £80 + VAT for an annual gas boiler service across our main North East service area. The useful question is not just the headline price, but what the engineer actually checks for it.
What is included in a proper boiler service?
A proper service should be more than a quick visual check. It normally includes a combustion and safety inspection, with the engineer checking the appliance against the manufacturer's requirements.
- Visual inspection of the boiler and flue
- Flue gas analysis with a calibrated analyser
- Gas pressure and gas-rate checks where required
- Ignition, burner and flame checks
- Controls and safety-device checks
- Heat exchanger, seals and gaskets inspected
- Condensate trap and route checked
- System pressure checked
- A written service record for your paperwork

Why boiler service prices vary
Price depends on the appliance, the work included, travel, and whether the company uses fixed published pricing or quotes individually. The cheapest visit is not good value if the important combustion and safety checks are skipped.
Service plan or one-off service?
A one-off annual service suits many newer boilers. A membership plan can make more sense if you value priority booking and ongoing cover. AR Heating's membership plans start from £8 + VAT per month; see the membership plans for exactly what each level includes.
Why the annual service matters
Safety: the visit checks that combustion and the flue are operating safely.
Warranty: manufacturers commonly require regular servicing in line with their warranty terms, so keep your service record.
Reliability: catching a worn seal, blocked condensate trap or early combustion issue is cheaper than waiting for a breakdown.
