Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government which energy efficiency measures are included in the "fabric-first approach to decarbonising buildings" set out in the Heat and Buildings Strategy (CP 388).

The Heat and Buildings Strategy is based on a 'fabric first' approach to decarbonising buildings by focusing on upgrading the building fabric before making changes to heating systems, to ensure the transition to low-caron heating is cost-effective and resilient.

Current schemes allow the installation of measures which improve the energy performance of a dwelling within the scope of the “Standard Assessment Procedure” (SAP) – which assesses the energy performance of dwellings. This can include measures such as solid wall insulation, cavity wall insulation, loft insulation, underfloor insulation, draught-proofing, air source heat pumps, ground source heat pumps, high heat retention storage heating, low energy lighting, solar PV, solar thermal and heating controls.
