Answer
Calculating Barnett consequentials of the Government's spending commitments is the responsibility of HM Treasury.
At almost £15 billion, the Warm Homes Plan is the single biggest public investment programme in energy efficiency in UK history. The Treasury has not yet confirmed the total Barnett consequential nor the specific appointment for Wales. More details on the Warm Homes Plan will be published soon.
As issues of energy efficiency, fuel poverty and heat are largely devolved Scotland, Wales and Northern Ireland have specific Net Zero strategies. We work closely with our counterparts in the Devolved Governments to ensure our strategies align.
