An annual boiler service is one of the cheapest ways to avoid expensive breakdowns, keep your boiler running efficiently and protect your manufacturer's warranty. Here's what's involved and what to expect to pay.
What does a boiler service cost?
As a rough guide, a standard boiler service in the UK typically costs in the region of £70–£120 for a single appliance, though prices vary by area, boiler type and engineer. Be wary of very cheap 'services' that are really just a quick visual check. We'll always tell you exactly what's included and give a clear price before we start.
What's included in a proper boiler service?
- Visual inspection of the boiler and its components
- Checking the gas pressure and flow
- Inspecting the flue and combustion (often with a flue gas analyser)
- Checking seals, the heat exchanger and key components
- Testing safety devices and controls
- A written report of the results
Why service your boiler every year?
- Catches small faults before they become expensive breakdowns
- Keeps the boiler running efficiently, which lowers your gas bills
- Required to keep most manufacturer warranties valid
- Confirms the boiler is safe and not producing carbon monoxide
Service vs gas safety check
A boiler service and a landlord gas safety check (CP12) aren't the same thing, though they're often done together. A service focuses on keeping your boiler running well; a gas safety check confirms gas appliances are safe and is a legal requirement for landlords.
