Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether his Department has made an assessment of the potential merits of using hydrotreated vegetable oil as a fuel source for households in off-gas-grid areas.

The Government expects heat pumps will be the primary technology for decarbonising off-grid buildings. The Government recognises that not all off-grid properties will be suitable for a heat pump and there will be a role for alternative low carbon technologies where heat pumps cannot be used.
