Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the impact of the absence of a statutory requirement for an annual service on the efficiency of domestic heating systems in non-rented properties.

Annual servicing of heating systems is recommended to ensure safety, more efficient heating and higher consumer comfort. Heating system warranties are often tied to an annual service and may be invalid if an annual service has not taken place.

The Government is seeking views on how regular heating system servicing can be encouraged or whether it should be mandatory through the consultation on Improving Boiler Standards and Efficiency, which closes on 21 March.
