Boiler service cost breakdown


Cost of an oil boiler service

Servicing an oil boiler involves several specific checks to ensure it runs efficiently and safely. This includes cleaning the boiler, checking the oil levels and filters and inspecting the flue and combustion releases. It also involves checking that the fuel lines are clear and in good condition. Due to the additional complexity and expertise required for handling oil boilers, the service cost is slightly higher than standard boilers. The average cost for an oil boiler service in the UK ranges from £80 to £120. It is important to hire an OFTEC-registered technician for servicing oil boilers.

Cost of a gas boiler service

Gas boiler servicing is essential for the safety and efficiency of your gas heating system. This gas boiler service involves checking the gas pressure and flow, inspecting the heat exchanger, burner, and main injector, verifying the seals and fans, and checking for any gas leaks. In the UK, the cost for a gas boiler service typically ranges from £70 to £110. Always ensure that the service is performed by a Gas Safe registered engineer to stay safe and maintain compliance with safety regulations.

Cost of an electric boiler service

If you have an electric boiler, you’ll need an electric boiler service. The service includes checking the heating elements, thermostats, wiring, and electrical connections. Furthermore, the engineer will make sure that the system is free from limescale buildup, which is a common issue in electric boilers. The average cost for servicing an electric boiler in the UK is between £70 and £100. As electric boilers have fewer moving parts than gas or oil boilers, their servicing might be less intricate. However, it is still essential for efficiency and safety.

Cost of a back boiler service

Back boiler services are necessary for some older types of boilers, typically located behind a fireplace. The service includes checking the gas connections, the heat exchanger, and the flue system, along with a general inspection of the boiler and its controls. Given their unique placement and design, servicing a back boiler often requires a fair amount of effort and time. The cost for servicing a back boiler in the UK generally ranges from £80 to £150, depending on the boiler's condition and accessibility.



How long does a boiler services take? 

The time taken to service a boiler can vary depending on the type of boiler and the complexity of the service required. Generally, a standard boiler service for a typical residential unit should take about an hour to complete. This includes a check of the boiler’s components, safety devices, and overall functionality. However, more complex or specialised boilers might require additional time due to their specific maintenance needs. Examples of these are oil boilers or back boilers. 

Here's a general timetable for different types of boiler services:

Heating engineer’s taskUsual timeframe
Standard boiler serviceApproximately 1 hour. This includes basic checks and routine maintenance tasks
Oil boiler serviceOil boilers require additional checks such as oil tank and filter inspection, which can extend the service time
Gas boiler service Around 1 hour. Involves thorough checks of gas pressure and connections, along with safety inspections
Electric boiler serviceAbout 1 hour. Given that electric boilers have fewer components, the service time is typically consistent with standard boilers
Back boiler service1 to 1.5 hours. The unique placement and complexity of back boilers often require a bit more time for a comprehensive service

It's important to note that these times are estimates. Actual service time can vary depending on the boiler's age, condition, and when it was last serviced. Also, if the engineer discovers any issues that require immediate attention, additional time may be needed to address these problems. Regular servicing, ideally once a year, ensures that your boiler remains efficient, safe, and less likely to break down, potentially saving you time and money in the long run.

  • Ask if there could be any additional costs, e.g. parts or extended labour, in case they find issues during the service.
  • If available, consider annual service plans offered by utility providers. These can be more cost-effective and provide peace of mind with regular maintenance.
  • Ensure easy access to your boiler and have any previous service records handy. This saves time and potentially reduces labour costs.
  • Set aside a contingency fund for any unexpected repairs that might be identified during the service.
  • Check if any new parts installed during the service come with a warranty, providing additional value and protection.
  • Discuss with the engineer any concerns about your boiler's efficiency and ask for tips on improving it. This will save money in the long run.
