The cost to have your boiler serviced in the UK in 2024 will normally be between £90£120.

Our research for this article includes a range of sources including British Gas, Checkatrade, and Moneysupermarket plus several well-established and local, independent boiler servicing companies.

British Gas Boiler Service Cost

Checkatrade Average Boiler Service Prices

Checkatrade aligns with British gas, estimating that the average cost to service a gas boiler in the UK currently stands at £100

They also provide estimates for other types of boiler including oil and electric combi:

Myjobquote & Moneysupermarket

Both these sites suggest that the average cost for a boiler service is lower than the figures we have already seen, it being £75£80 respectively.

Whilst it may be possible to find companies willing to service your boiler at this price level, our research suggests they are no longer realistic price ranges.

The consensus among a number of local and independent gas boiler services companies places the current range to be between £90£125.

What Factors Will Affect the Cost of Servicing a Boiler?

Factors that might affect how much you have to pay to have your boiler serviced include (but are not limited to):

  • Where you live: The cost of having your boiler serviced is likely to cost more than the UK average if you live in London or other parts of South East England. 
  • The type of boiler you own: Servicing a combi boiler is a much quicker and simpler process than servicing a system or an oil boiler, and is therefore likely to be significantly cheaper as a result. 
  • The number of local engineers: If you live in a rural or remote location with few local engineers you will likely have to pay a higher premium to have your boiler serviced. 
  • Time/Day of the week: Like many service professionals gas safety engineers have peak and off peak times – if you require that your boiler service takes place during peak times this will likely incur a higher cost.

Always make sure you get a range of quotes for your annual boiler service to make sure you are getting the best possible deal. 

What Does a Full Boiler Service Include?

A boiler service in the UK is an essential inspection and maintenance process conducted by a certified Gas Safe engineer that takes place once every year.

The key goal of this service is to maximise the boiler’s performance, safety, and efficiency. 

A full boiler service is comprised of the following elements:

1. Visual Inspection

  • Examination of the boiler and its control settings.
  • Checking for signs of wear or damage.
  • Ensuring proper installation and no visible leaks.

2. Inspection of Internal Parts

  • Removal of the boiler casing to access internal components.
  • Detailed check of the heat exchanger for blockages or damage.
  • Inspection of the burner for efficient combustion.
  • Evaluation of the main injector and its condition.

3. Flue Check

  • Verification of secure flue installation and proper termination.
  • Checking for obstructions or leaks in the flue system.
  • Ensuring the flue is correctly taking away harmful gases.

4. Gas Pressure Check

  • Measurement of gas pressure to verify it aligns with manufacturer specifications.
  • Adjustment of gas pressure if necessary for optimal performance.

5. Boiler Firing Up

  • Operation of the boiler to check for any startup issues.
  • Monitoring for unusual noises or operational glitches.
  • Assessing overall performance during active operation.

6. Clean Up

  • Thorough cleaning of components like the heat exchanger, burner, and fan.
  • Removal of any debris or sediment that could impair efficiency.
  • Reassembly of the boiler after cleaning and checks.

After these steps, the engineer will provide a detailed boiler service report or certificate. 

This report is essential for homeowners, not only for warranty purposes but also as a record of the boiler’s condition and maintenance history. 

Regular servicing can significantly contribute to the boiler’s longevity, efficiency, and safety. 

Moreover, in the UK, for rented properties, it is legally required to conduct these checks annually to ensure tenant safety and compliance with gas safety regulations.

Frequently Asked Questions (FAQs)

Is it worth getting a boiler serviced?

Absolutely. Servicing your boiler is a smart investment for several reasons. 

It ensures your boiler is running safely and efficiently, which can save you money on energy bills in the long run. 

Regular servicing also helps in identifying potential issues early, avoiding more expensive repairs down the line. And, importantly, your boiler’s warranty may be invalid if you do not have it serviced annually.

While the cost for a boiler service, such as the average cost or specific fees like British Gas’ boiler service cost, may vary, the long-term benefits of maintaining your boiler’s health and efficiency are significant.

How often should a boiler be serviced?

It is recommended to service your boiler annually. 

Regular servicing ensures it operates at peak efficiency and identifies potential issues before they become major problems.

Is there a benefit to getting a boiler service and gas safety certificate together?

Getting a boiler service and gas safety certificate together can be beneficial, especially for landlords or property managers. 

It not only ensures the boiler is functioning efficiently and safely but also complies with legal requirements for rental properties. 

Often, packages that include both services can be more cost-effective than getting them separately.

Are there any hidden costs in boiler servicing?

Typically, a boiler service quote should be all-inclusive, but it’s important to check with your service provider. 

Some might charge extra for replacement parts or for extensive cleaning if your boiler is particularly old or hasn’t been serviced in a while. 

It’s advisable to ask for a detailed breakdown of the service cost beforehand.


Regular servicing not only prolongs your boiler’s life, but also ensures optimal performance, potentially lowering long-term expenses. 

For homeowners and landlords alike, staying on top of these annual checks is crucial for maintaining warranties and legal compliance, making boiler servicing a necessary and valuable aspect of property upkeep.

However, despite how well we look after our boilers, ensuring we never miss their annual service, eventually the time comes when they need replacing. 

If you are coming towards that time, you can start identifying your perfect replacement boiler right now.
