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 potential merits of integrating hybrid-fuelled boilers with (a) electric air-source heat pumps and (b) smart technology to help decarbonise residential properties.

Hybrid heat pumps, a heating system comprised of a fossil fuel boiler and a heat pump, have the potential to play an important role in heat decarbonisation over the coming years.

The Government will continue to consider their potential and is consulting further through the ‘Raising product standards for space heating’ consultation, which is open until 25 March 2025.

The previous Government consulted in April 2024 on a proposal to require smart functionality for electric heating appliances with high flexibility potential and to extend this to hybrid heat pumps. A response to that consultation will be published in due course.
