Question reference: S6W-22661

  • Asked by: Brian Whittle, MSP for South Scotland, Scottish Conservative and Unionist Party
  • Date lodged: 2 November 2023
  • Current status: Answered by Patrick Harvie on 16 November 2023


To ask the Scottish Government what assessment it has made of the suitability of (a) whole-house renewable heating systems and (b) other renewable solutions for retrofitting on existing housing stock, and how many existing homes it estimates there currently are that are not suitable for retrofitting these systems.


On behalf of the Scottish Government, Element Energy conducted analysis of the technical suitability of low-carbon heating technologies in Scottish domestic buildings. A copy of this report is available here: Scottish Government (2020). Technical Feasibility of Low Carbon Heating in Domestic Buildings, .

We have recently published research by ClimateXchange that considers options for a methodology to assess the suitability of whole-building heating systems and we are currently undertaking work to develop options for such a methodology for further consideration.

We will consult during 2023 on proposals for a Heat in Buildings Bill to phase out polluting heating systems in Scotland’s homes and buildings and move to clean heating systems. Any regulations introduced will be technology-neutral since different homes and buildings will require different clean heat solutions (including heat pumps, heat networks and direct electric heating systems).
