Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what steps he is taking to encourage the installation of smart-enabled hot water cylinders.

The Government intends to introduce a smart mandate, which will require heat pumps, storage heaters and heat batteries to have smart functionality, from the mid 2020s. The Government is also considering whether to extend the scope of the mandate to include other appliances, such as hot water cylinders.

The Government is also seeking to improve standards regarding hot water cylinder efficiency and has sought feedback on possible options for achieving this in the recent consultation “Improving Boiler Standards and Efficiency.”
