  • Asked by: Sarah Boyack, MSP for Lothian, Scottish Labour
  • Date lodged: 2 November 2023
  • Current status: Answered by Paul McLennan on 14 November 2023


To ask the Scottish Government what information it holds on how many (a) public sector buildings, (b) privately-owned homes and (c) housing association homes have double glazing that was installed before 2002.


The Scottish House Condition Survey (SHCS) provides a snapshot of the Scottish housing stock in each survey year including the construction age and built form of Scottish domestic buildings. The SHCS records double glazing for occupied dwellings, however this is recorded as installed pre or post 2003, when higher requirements for double glazing were introduced. The SHCS does not record data on all public sector buildings, just Local Authority owned homes, therefore complete information requested is not available in this form.

The most recent estimates of households with double glazing installed pre 2003 broken down by privately owned, local authority and housing association is presented in the table below.

2. The SHCS is a sample survey and therefore all figures are estimates which lie at the midpoint of a confidence interval which depends primarily on sample size. A statistical tool for calculating 95% confidence intervals around these estimates can be found at Scottish House Condition Survey: Local Authority Analysis 2017-2019 - ( .

We will shortly consult on proposals for a Heat in Buildings Bill. This will include proposals to set a minimum energy efficiency standard for homes in Scotland - ensuring they are better insulated and driving down emissions to meet our targets.
