Why Do You Need to Service Your Oil Boiler?

Although boiler servicing is often seen as an 'unnecessary expense', having your boiler serviced regularly is important for three key reasons:

  1. Safety:  If your boiler is not combusting properly it could be giving off lethal carbon monoxide fumes. During your service an engineer will check the boiler for these leaks, to make sure that it is safe.

  2. Reliability:  Un-serviced boilers are more likely to breakdown or develop problems. By regularly servicing your boiler, you will reduce the chance of expensive maintenance issues.

  3. Efficiency: If oil boilers are not serviced annually they can “soot-up”. This means that your boiler will be less efficient, as it will need to use more fuel to maintain a regular temperature. During the service an engineer will clean out the soot, making your boiler more efficient and cost-effective.

WARNING:  When booking a oil boiler service, always check that your engineer is registered with OFTEC.

What Is Included in an Oil Boiler Service?

During your service, the engineer will check that your boiler is in good working condition, as well as testing the safety and efficiency of your system. Oil boiler servicing usually takes around one hour, during this time the engineer will:

  • Visually inspect the boiler and all associated pipes or areas (including your oil tank and supply pipe), to make sure that they comply with current safety regulations.

  • Inspect and clean out the flue.

  • Replace the boiler nozzle.

  • Check for water in your oil tank.

  • Use a flue gas analyser to check combustion.

  • Check the supply pipe for any signs of leakage.

  • Remove the boiler casing and clean internal components (like the heat exchanger and burner).

  • Test all safety systems to make sure that they are functioning correctly (this includes any thermostats, pressure relief valves and burner lockout devices).

  • Ask if you have experienced any issues with the boiler.

  • Turn the boiler on to check that it is working correctly.

Once your service is complete the engineer will give you an OFTEC CD/11 form which lists everything that has been done as part of the service.

How Much Does it Cost to Service Your Oil Boiler?

Oil boiler servicing costs tend to vary across the UK, as engineers in England, Scotland, Wales and Northern Ireland often use different pricing structures. For this reason, the best way to get an accurate idea of how much an oil boiler service will cost you, is to compare actual service quotes from engineers in your local area.
