Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if he will make an assessment of the effectiveness of his Department's policy on periodic hydraulic balancing of hydronic domestic heating systems for ensuring that consumers’ fuel bills are minimised; and if he will make a statement.

The Government is clear that hydraulic balancing is an expected practice to be completed by heating engineers when a heating appliance, including a natural gas boiler, is installed in a wet central heating system.

The Government is seeking views on how to ensure hydraulic balancing and other installation practices take place at the time of install and how and whether to encourage hydraulic balancing as part of heating system servicing, through the consultation on Improving Boiler Standards and Efficiency, which closes on 21 March.
