One-off boiler servicing’s are usually cheaper than a boiler plan. However, paying for a cover plan will cover you for multiple services in a calendar year.

Each boiler type will require a different service, so the cost can vary due to the amount of work required to complete the service.

The age of your boiler will affect the price of servicing, as older boilers will require a bigger service than newer boilers.

Service costs for different boiler types

Your location in the UK and your choice of heating engineer are the biggest deciding factors for the cost of a boiler service. That said, the type of gas boiler you have can also play a part in determining the price. Here, we’ve outlined the typical service costs for different boiler types.

Combi boiler service costs

Combi boilers are compact, cost-effective and energy efficient and are ideal for homes where space is precious.

System boiler service costs

System boilers are common for homes that have more than one bathroom due to it being able to provide a constant hot water source with the help of a hot water cylinder.

Regular boiler service costs

Regular boilers (also known as heat only, open vent and conventional boilers) are common in homes that are in low water pressure areas, where you will have a hot water cylinder and water storage tank to provide hot water to multiple bathrooms.

The price of servicing the different boiler types in 2025 are all very similar with the price estimated to stay between £109-120, despite the different sizes of the systems.

How often should I have my boiler serviced?

Boiler servicing should be an annual task carried out by homeowners. Having your boiler checked regularly by a specialist ensures:

Boiler service vs boiler repair

It’s important to note that a boiler service is different from a boiler repair – a service should be carried out once a year to check for any issues, whereas a repair will only need to be carried out in the event that you experience problems with your boiler.
