Combi Boiler Service


combi boiler service and repair

Combi boilers (also known as combination boilers) have become more and more popular over the past few years, with many homeowners electing to replace older, more complicated central heating systems with a smaller, more compact combi boiler system. In fact, it is estimated that over half of new boiler installations in the UK are combi boiler installations.

Why Do You Need to Service Your Combi Boiler?

Considering how hard these compact boilers work to heat your home, it is important to get your combi boiler serviced at least once a year by an OFTEC or Gas Safe registered engineer.

As well as making sure your boiler is in good, working condition, an annual combi boiler service can:

  • Help you save money by making your boiler more efficient.

  • Reduce the chance of expensive maintenance issues or breakdowns.

  • Make your boiler more reliable.

  • Protect your family from lethal carbon monoxide leaks.

What Is Included in a Combi Boiler Service?

While combi boiler servicing can differ slightly depending on whether you have a gas combi boiler or an oil combi boiler, you can generally expect the engineer to do the following things during the service:

  • Carry out a visual inspection of the boiler and all related areas, to make sure that they adhere to current safety standards and legislations.

  • Complete a ‘firing test’ to make sure that the boiler is functioning correctly.

  • Check that the flue is providing adequate ventilation for the boiler, and is not blocked by debris.

  • Carry out a flue gas analysis test to check for carbon monoxide.

  • Clean away any dirt or debris in the system, and repair or replace any damaged parts.

  • Carry out an inspection of the internal components (e.g. heat exchanger, burner).

  • Remove and clean the boiler casing (if required).

  • Turn the boiler on, to make sure that it is working properly.

A combi boiler service usually takes around one hour to complete. When the engineer is finished, they should present you with a completed service report, which will contain details of their work.  

How Much Does a Combi Boiler Service Cost?

Typically, oil combi boiler service costs are slightly higher than gas combi boiler service costs. It can be difficult to estimate exactly how expensive a service will be though, as prices can be affected by a number of factors.  

As the ‘best' combi boiler service price can differ radically from town to town, the easiest way to get an accurate idea of how much your service will cost is to compare quotes from engineer based in your local area.
