What Does a Boiler Service Cost in the UK?
An annual boiler service keeps your boiler running efficiently, reduces breakdown risk, and keeps your warranty valid. Most Gas Safe engineers charge between £60 and £120 for a standard boiler service.
Typical Boiler Service Prices
- Standard gas boiler service: £70 to £120
- Service through a national provider (British Gas, Homeserve, etc.): £90 to £150
- Oil boiler service: £100 to £180
- LPG boiler service: £80 to £130
What a Boiler Service Includes
- Checking the flue and combustion gases
- Inspecting the heat exchanger, burner, and ignition system
- Checking gas pressure and flow
- Testing safety devices and controls
- Checking the condensate trap and expansion vessel pressure
- Visual check of pipework and fittings
At the end of the service, the engineer completes a service record and advises you of any issues. Parts needed are quoted separately.
Why Annual Servicing Matters
Under most boiler warranties, an annual service by a Gas Safe registered engineer is a condition of the cover. Skipping a service can invalidate the warranty and leave you facing full repair costs. Carbon monoxide is also a serious concern — all homes with a gas boiler should have a CO alarm (£20 to £50).
Gas Safe Registration: Non-Negotiable
By law, all gas work in the UK must be carried out by a Gas Safe registered engineer. Verify any engineer at gassaferegister.co.uk. You can also ask to see their Gas Safe ID card when they call.
Boiler Cover Plans vs One-Off Service
National providers offer annual cover plans including a service plus breakdown repair, typically £20 to £50 per month. For a boiler under five years old, a one-off annual service from a local independent Gas Safe engineer usually offers better value. As boilers age beyond 10 years, cover becomes more worthwhile given the likelihood of repairs.
