Oil boiler service cost

An annual oil boiler service costs around £100—around 25% more than a gas boiler service. Oil boilers cost more to service because they are dirtier than gas boilers and require storage tanks and oil supply pipes that need to be checked for water contamination and oil leaks.

What should a boiler service include?

In short, a boiler service should include a full check of your boiler, controls, flue and ventilation to make sure there are no leaks, corrosion, damage or unsafe fumes. Your boiler service will include:

  • Inspect the boiler casing to see it’s properly sealed
  • Visual inspection for corrosion or leaks
  • Clean boiler parts inside
  • Check that all components are sealed properly
  • Check that combustion and burner pressure are within limits using a flue gas analyser (FGA) test
  • Check the ignition, heat exchange and spark electrode

The cost of the boiler service will not cover the cost to repair any issues uncovered by the inspection and service. If your boiler needs repairs, you'll need to pay extra for them. If your appliance is still under warranty, however, needed repairs may be covered.

As an alternative to paying for one-off annual boiler services, you might opt to pay for "boiler cover". This typically costs more (roughly £15 a month) and will include an annual boiler service as well as repairs, depending on the terms of your cover.

Finally, be sure that whoever comes to service your boiler is a Gas Safe engineer. You can check that your engineer is Gas Safe registered here.

Is a boiler service included in home emergency insurance?

No, boiler service is not included in home emergency insurance, whether you buy a cheap home insurance policy or an expensive one. Home emergency cover doesn't include routine maintenance. That said, many home emergency policies require that you have your boiler serviced regularly or they won't cover any emergency breakdowns.
