How much does a boiler service cost in 2022?

All boiler service costs in this article are correct as of 2022

We all rely on boilers to keep our homes warm and toasty, and our water piping hot.

But, like our cars and other pieces of complex machinery, our boilers need regular servicing to make sure they’re working at their best, and don’t have any underlying problems that can cause you headaches in the future.

This article breaks down boiler service costs so you know what to expect.

Does my boiler need a service?

Experts recommend that you have a boiler inspection every year to make sure it’s running as it should be.

If it’s been more than 12 months since your boiler was last serviced, it’s a wise move to get one booked in.

If you’ve just moved into a new home, you should schedule a boiler service to make sure there are no problems with the boiler - the last thing you need is to be surrounded by unpacked boxes without any heat or hot water.


The other time to get a boiler serviced is if you have any concerns about how it’s performing, or if you’ve spotted any particular issues.

If the boiler is making unusual noises, has leaks from any surrounding pipes, then you should have an expert take a look. Similarly, if the boiler is turning itself off, or is unable to hold pressure, it’s wise to get it looked at to see if there are any serious issues.

Issues in your wider heating and water system, such as low pressure through your taps, water not getting hot, and radiators having cold spots could also be signs of underlying issues with your boiler.

Remember, you should only hire Gas Safe Registered tradespeople to work on your boiler.


How much does a boiler service cost?

The average cost of a boiler service is around £80, though prices usually begin at around £70 and go up to around £100.

This does not include the cost of any extra repairs that the tradesperson may need to do if they find a fault that needs fixing.

Large, national firms will probably have a set fee for boiler servicing, excluding extra costs for parts and repairs, which is likely to be higher than that of independent tradespeople.

Pricing in London often tends to be higher than elsewhere in the country.

You can pay this is a one-off payment to the tradesperson, but many people prefer to pay for longterm coverage packages either with their boiler manufacturer, home insurance or utility supplier which includes an annual service.

Some suppliers will insist upon annual services to maintain the warranty on the boiler.

Combi boiler service costs

Although combi boilers can cost more than gas boilers to purchase up front, servicing is usually priced very similarly.

An inspection will usually cost around £75 to £100. Pricing is similar for system boilers as well.

What does a boiler service cover?

An engineer will check several things when they service your boiler. As standard, they will usually inspect the controls, the pressure, the main internal components, the safety devices, the water and gas pipework, the electrical connections and all the seals.


MyBuilder Top Tip

Many people only think about their boilers when cold weather sets in and they have to fire the heating up. Don’t leave it too late though - as the dead of winter is the last time you want to find out your boiler does have a problem.

Gas engineers will typically have lighter schedules in the summer as they deal with fewer emergency calls, so get it booked during warmer months to have peace of mind all year round.

They will also check the flue, which removes all the waste products from the boiler, and clean anything that needs be cleaned.

How long does a boiler service take?

Assuming your boiler is working as it should be, a service can be done in less than an hour. Boiler inspections are usually a major part of a gas engineer’s job, so they’ll have the process down to a fine art.

If there are specific repairs to carry out, or processes such as performing a power flush, this will take extra time.

Considering how quick the process can be, there’s no excuse not to get it done - especially when it can save you the hassle and cost of buying a new boiler.
