Boiler Service Cost & Prices 2023

No one wants to have to deal with a broken boiler. They can become a particular problem during the colder months and when older and vulnerable people are involved.

A boiler service can ensure that doesn’t need to be the case. A boiler service ensures your boiler runs smoothly and works for longer so that you don’t need to pay the expensive costs involved when installing a new boiler.

Thi article will cover what you can expect to pay for a boiler service, factors that affect the cost, plus common questions around servicing a boiler.

Average Cost

We contacted 54 different companies across the UK that offer boiler services. The quotes we received were for a service of a typical gas boiler, however, most companies charge the same for oil and eelctric boilers. Quotes are a one-off price (no annual agreements) and exclude VAT.

Factors That Affect the Cost

Whether Extra Problems are Found

A boiler service doesn’t usually include extra repair work, for example if some defects or worn parts are found. If there is an issue with the boiler, then you will need to pay extra, but the boiler tradesperson who does the work shouldn’t do anything extra without confirmation from yourself first.

If the boiler already has a fault or is not operating correctly, a service may not be needed and you will just pay for the repair work. This will involve a fault diagnosis and rectification work usually at their normal hourly rates (typically £40 – £60 per hour of labour cost + cost of materials). This could be a new fan for example.

Size of Company

We received many quotes from local companies that serve a small region when compared to larger companies. Larger companies will typically charge more because they have higher overheads they need to account for. This could be anywhere from 25-50% higher.


Labour costs in London and the south of England are generally more expensive than elsewhere.

If the contractor needs to travel beyond a certain radius, then they may add an extra fee on top. Unless you live in a very rural location or want to use a boiler servicer that operates further afield, you shouldn’t need to pay extra.

Back Boiler and Fire

This is the price to service any boiler except a back boiler and fire which would be closer to £120.

Boiler Service vs Cover Plan

Boiler services can be done either as a one-off payment to an engineer or via an annual cover policy or insurance. The amount these will cost will depend on things such as the coverage level, type of boiler and any previous claims.

It may be more cost effective to  take out a plan that includes other appliances, electrical and gas supplies. It will give you pece of mind and for a boiler of more than 8 years, it is likely to be coming to the end of it’s use with many issues cropping up. Therefore, it could give you your money’s worth.

Boiler cover costs around £9-£13 per month depending on the provider.  However, a one-off boiler service is usually quite cheap overall as seen with the prices above.

How Often Should I Service My Boiler?

It’s a good idea to have an annual boiler service to ensure any issues are solved before they become a bigger problem. Many boiler manufacturers require annual servicing as part of their warranty too.

If you do it, then it’s worth having a service done in summer so you can be more confident no problems will occur over the winter months.
