Boiler service cost UK 2026
If you’re looking for current boiler service prices in the UK, then the following figures provide an up-to-date guide:
| Service | Typical 2026 price |
| Domestic gas boiler | £80–£120 |
| Domestic oil boiler | £75–£110 |
| Domestic electric combi boiler | £70–£110 |
| LPG boiler | £90–£125 |
As you can see from the table above, the benchmark for a typical domestic gas boiler is £80-£120.
That’s considerably less than you’ll pay for an emergency repair if your boiler breaks down.
What does a boiler service include?
A boiler service begins with a visual inspection, but that isn’t where it ends.
A qualified Gas Safe engineer will inspect and test the appliance to establish that it’s safe, efficient, and operating correctly.
The precise procedure they follow depends on your boiler’s manufacturer, the model, and any specific servicing instructions.
However, a typical gas boiler service includes:
- Visual inspection of the boiler
- Inspection of the flue
- Checking ventilation
- Checking gas pressure and flow
- Testing combustion
- Checking carbon monoxide levels
- Testing safety controls
- Inspecting electrical connections
- Checking the burner
- Inspecting the heat exchanger
- Checking seals and gaskets
- Inspecting accessible pipework
- Cleaning relevant components where required
- Checking condensate arrangements
- Recording the results of the service
The engineer should also identify any faults or concerns that require further attention.
Note though that a service doesn’t normally include the repair itself, nor the replacement of any faulty components.
If these are required, you should be quoted separately.
At Bumblebee, we provide a thorough boiler service.
We don’t only check the appliance to make sure it’s safe and working correctly; we also look for any developing problems. Addressing these early on can prevent breakdowns and save you money.

Which factors affect boiler service cost?
There are several factors that impact a boiler service price, including:
Boiler type
A standard domestic gas combi boiler is usually a straightforward service.
However, if your hot water and heating are running on oil or LPG, then a boiler may require different or extra checks.
For comparison, Checkatrade’s 2026 figures are:
-
- Gas: £80–£120
- Oil: £75–£110
- Electric combi: £70–£110
- Commercial boiler service up to 40kW: £95 minimum call out fee
Boiler size and complexity
The size of the boiler as well as the complexity of the overall heating system will affect the amount of time an engineer may need to complete the work.
A small boiler in a one-bedroom flat will take less time to service than a large boiler serving a fully occupied five-bedroom home.
Multiple appliances, pumps, controls, and associated equipment will all add extra time to the service and potentially extra costs.
Location
Where you live will impact on the cost of your service.
Boiler service costs are generally higher in London and the south of England, with data from Checkatrade and Check The Quote suggesting prices are around 10% above the national average.
Boiler condition
A well-maintained boiler is usually straightforward to service.
When an engineer finds corrosion, damaged seals, leaks, faulty components, or irregular combustion readings, additional work may be required.
Extra work isn’t normally included in the boiler service cost.
Accessibility
Boilers can be located in difficult to reach locations, particularly in older properties.
When that’s the case, additional panels may need to be removed or extra work carried out to safely access components, all of which adds to the extra cost.
Does a boiler service include repairs?
No, repairs aren’t normally included in the price of a standard boiler service.
As explained above, boiler service prices in the UK covers the cost of the engineer’s inspection, servicing, and testing work.
If an engineer discovers the fault, they should explain the nature of the problem and recommend the repair that might be required.
Any parts or additional labour will be charged separately.
Checkatrade’s 2026 figures put boiler repairs at £120–£750, with an average of around £300.
While servicing doesn’t guarantee that your boiler won’t break down, it does give the engineer the opportunity to identify any faults. These can be addressed before they become serious.
If your boiler makes unusual noises, regularly loses pressure, or switches off, don’t wait for your next annual service.

Boiler service plans: Are they worth it?
Boiler service plans allow you to spread the cost of your annual boiler service and can provide some additional protection in the event of your boiler breaking down.
Depending on the level of cover, a plan may include:
- Annual boiler service
- Boiler breakdown cover
- Parts and labour
- Emergency callouts
- Central heating cover
Plans are structured differently and will have different levels of cover and exemption.
Before committing to cover, check:
- Whether the annual service is included
- Whether parts are covered
- Whether labour is covered
- Whether there is an excess
- Whether older boilers are excluded
- Whether there is a waiting period
- Whether there are limits on claims
The cost of a plan also needs to be compared with simply paying for an annual service.

How much does a commercial boiler service cost?
There is greater variation of price when it comes to commercial boiler servicing compared to domestic equivalents.
That’s because a small commercial boiler and a large commercial heating installation are very different jobs.
The final price will depend on:
- Boiler output
- Number of appliances
- System complexity
- Plant room layout
- Accessibility
- Controls and associated equipment
- Required testing
- Whether repairs are necessary
Checkatrade currently gives a minimum call-out fee of around £95 for a commercial boiler up to 40kW.
This is a call-out benchmark rather than the typical total service price. For larger, more complex installations, the cost may be significantly higher.
If you have a commercial heating system that’s due a service, you should request a quote.

How to save money on your boiler service
If you’re looking to save money on your boiler service, it’s important not to simply opt for the cheapest engineer.
Make sure you’re getting a thorough service at a competitive price to reduce the likelihood of expensive problems occurring later.
Compare like-for-like quotes
Ask whether the price includes:
- VAT
- Labour
- Standard service checks
- A service record
- Call-out charges
A £70 service isn’t necessarily cheaper than a £100 service if the cheaper price doesn’t include everything you need.
Book annually
Regular servicing gives an engineer an opportunity to identify developing problems before they become major faults.
Annual servicing may also be necessary to maintain your manufacturer’s warranty or guarantee.
Book before winter
Heating engineers tend to be busiest when the weather turns cold and boilers start failing.
Having your boiler checked before winter also gives you time to arrange repairs if any problems are identified.
Don’t ignore small issues
If a boiler is making unusual noises, repeatedly losing pressure or switches itself off, this shouldn’t be ignored. Small faults can sometimes develop into a more expensive breakdown.
Consider a service plan carefully
If your boiler is older and has a history of breakdowns, the additional repair protection can make a service plan more economical than a one-off annual service. Work out the annual costs and check what it includes.
