Question ref. S6W-01910
Asked by: Liam Kerr, North East Scotland, Scottish Conservative and Unionist Party
Date lodged: 27 July 2021


To ask the Scottish Government how much it estimates it will cost for a typical hard-to-treat off-gas grid home rated between EPC (Energy Performance Certificate) Bands E and G to achieve EPC Band C by 2025.

Current status: Answered by Michael Matheson on 20 August 2021


Although there is no fixed definition of what a hard to treat home is, we estimate that the average cost of upgrading an off-gas grid property with an initial EPC rating between Band E and Band G to an EPC Band C could be in the region of £17,000.

As set out in our draft Heat in Buildings Strategy, the cost for an individual dwelling can differ from this average depending on the building type, materials, existing levels of energy efficiency and type of heating systems being replaced.
