To ask the Scottish Government whether it will provide (a) an updated estimated cost to decarbonise homes and workplaces and (b) the methodology behind that estimate, which it calculated to be "in the region of £33 billion" in its Heat in Buildings Strategy, published in October 2021, in light of increased levels of inflation and other increased costs since publication.
Information setting out the requested methodology is in the public domain: Heat in building strategy modelling: EIR release - gov.scot (www.gov.scot) .
We are committed to delivering a just and fair transition to net zero, where the distribution of costs and impacts protects those in the most vulnerable circumstances while also optimising benefits for everyone. This means continuing to take account of changes in the external environment so that our modelling of funding and support remains appropriate. We are currently reviewing our cost estimates to deliver the heat transition on this basis, and will provide a further update in due course.
