How Much Does It Cost to Service a Boiler?
£60 – £120
per service
A boiler service costs £60 to £120 and should be carried out annually by a Gas Safe registered engineer. The service includes checking the heat exchanger, burner, flue, seals, and controls. Annual servicing maintains the manufacturer warranty, improves efficiency, and reduces the risk of a breakdown during cold weather.

Prices vary by region, property type and tradesperson. Always get at least two quotes.
What affects the price?
Boiler type - combi boilers are most commonly serviced; system and conventional boilers with separate cylinders take slightly longer
Engineer location - rates vary significantly by region, with London and the South East typically 20-30% higher
Service plan vs one-off - annual service plans bundling servicing with breakdown cover cost less per service
Remedial work identified - if the service reveals a failing part, additional repair costs will apply on top of the service fee
Labour vs materials
A boiler service typically takes 45-75 minutes. The cost is almost entirely labour, as no parts should be required for a routine service.
