Boiler service cost
by
Checkatrade

Regular maintenance is the best way to keep a boiler running safely and efficiently, but how much does an annual boiler service cost?

When the summer is in full swing, it’s easy to put an annual boiler servicing on the backburner. When the colder months creep in, we realise once more the importance of keeping our boilers in good working order.

A professional heating engineer can identify any problems early on, saving you costs and preventing unexpected breakdowns. Use our handy search bar to find a qualified heating engineer in your area or read on to discover the average prices you can expect for this job.

Average boiler service costTop reasons to service your boiler

Heating engineers recommend an annual boiler service for several reasons, including:

  • To minimise the risk of Carbon Monoxide poisoning
  • Keeping your running costs reasonable
  • To prevent breakdowns
  • To  lengthen the lifespan of your boiler
  • Validating manufacturer warranties

Of course, there are times in which a boiler service will be required to fix an urgent issue. If the thermostat isn’t responding, the boiler switches off for no reason, your utility bills are higher than normal or your radiators are cold, it’s time to call in the professionals.

Average boiler service cost

An annual boiler service cost can either come in the form of a one-off fee of around £80 for a 30-minute service or an annual charge for insurance.

Type of coverUnitCost+VAT (Range low - high)Average cost
Boiler & central heating coverAnnual fee£180-£300£240

On average, boiler and central heating cover costs fall between £180-£300, but this will cover you for any breakdowns. Paying a one-off fee should work out cheaper, but the yearly cover will give you full peace of mind. If you have home insurance, speak to your provider about adding boiler insurance to the package. This should cost less than taking out a separate policy.

If your boiler is broken beyond repair, a new boiler will need to be fitted. Head on over to our new boiler cost guide to get an idea of prices.

How much does a gas boiler service cost?

A one-off gas boiler service can cost anything between £60 and £100, with £80 being the average that homeowners pay for gas boiler servicing. During a gas boiler servicing, a specialist Gas Safe engineer will inspect the boiler and controls to check for functionality. They will also check for leaks to ensure the pressure is correct and test the flue in case of toxic fumes.

How much does an oil boiler service cost?

Since oil fired boilers are “dirtier” than gas or combi boilers, regular servicing is essential to ensure maximum fuel efficiency and prevent the boiler from emitting harmful fumes. Prices can vary greatly depending on your location as well as the make and condition of the boiler, with average costs sitting between £50 and £180.

How much does a combi boiler service cost?

The average price of a combi boiler service is around £72, although the work can cost anywhere between £60 and £100. Large national firms tend to charge around 25 to 50% more for a boiler service than local businesses. Generally speaking, combi boilers are less prone to breakdowns than gas and oil boilers, so service costs may be cheaper in the long run.

If you’re thinking about replacing a gas boiler with an electric boiler, familiarise yourself with the average costs in advance.

Commercial boiler service cost

It isn’t only residential units that need maintenance. For a commercial boiler of 40 kW or under, the cost for service is a call-out fee of £79. Alternatively, you can choose to pay extra as part of your insurance plan to have call-out fees included as part of your cover.

FAQS

Combi boiler service costHow often should a boiler be serviced?

It’s worth getting your boiler serviced every 12 months at least. Doing so in summer can ensure it’s working properly ahead of the colder months and prevent you from tapping into your Christmas funds for an urgent repair.

How do you service a boiler?

How you service a boiler will depend on the type of boiler (i.e. gas, electric, oil.) For a gas boiler service, a visual check should be performed to ensure the boiler and pipework are correctly positioned.

The boiler casing should then be removed to clean the internal components and check for any problems. Unless you are qualified to do so, it’s essential you have your boiler serviced by a qualified engineer. They will be able to ensure your boiler is working safely and carry out any potential repairs.

Is it worth getting a boiler serviced?

Getting your boiler serviced does come with an upfront cost, but doing so will give you peace of mind that your boiler is running efficiently and isn’t at risk of breaking.
