Annual boiler service by a heating engineerAnnual boiler service by a heating engineer

An annual boiler service keeps your boiler running safely and efficiently — and it's usually required to keep your manufacturer's warranty valid. It's one of the cheapest and smartest ways to avoid a costly winter breakdown.

Why an annual service matters

  • Keeps your warranty valid (most makers require it)
  • Catches small problems before they become expensive
  • Keeps the boiler running efficiently, lowering bills
  • Confirms the boiler is safe and not leaking carbon monoxide

What's included in a boiler service

A Gas Safe engineer will inspect and test the boiler's operation, check the flue and combustion, test gas pressure and safety devices, clean key components, and check for leaks or corrosion. They'll finish with a service record for your files.

How much does a boiler service cost?

A standard boiler service typically costs £70–£120. Many engineers offer it as part of an annual cover plan. Booking in late summer or early autumn avoids the winter rush.
