Average Cost of an Annual Boiler Service

The average cost of a boiler service is £100 including VAT in the UK. Prices vary depending on where you live, the type of boiler and other factors. For example, an annual gas boiler service in London costs around £124 including VAT, while Manchester residents pay around £95 and those in Birmingham pay around £82 for their boiler service (note, firms in Manchester and Birmingham are less likely to be VAT registered).

Why is London so much more expensive than other cities? The answer lies in the VAT.

Note that cities like Manchester and Birmingham have loads of small, independent non-VAT-registered engineers. Because you aren't paying that extra 20% tax to a local "man-with-a-van," the real-world price stays lower, averaging around £70–£85.

But because a bulk of London firms are large enough to be VAT-registered, you are almost always paying the 20% tax, pushing the average to £124.

When you average the expensive South (£124) with other areas like the North/Midlands (£75), the geographical average lands right on £100.

Type of Provider

The average cost of a boiler service from a national provider (including energy companies, manufacturers, plumbing companies, etc.) is around £100, which is around 18% more than the average of £85 charged by local independents for a gas boiler service. Using a national service such as British Gas, Home Serve or Scottish Power usually costs more than using a local independent service.

British Gas charges £109 for a boiler service, while SSE charges £95, Scottish Power charges £115 and Home Serve charges £120—excluding VAT.

Oil boiler service cost

An annual oil boiler service costs around £150—around 50% 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:

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.
