Energy Performance Certificates: Wales
The question
To ask the Secretary of State for Energy Security and Net Zero, with reference to pages 37 and 38 of 'Improving the energy performance of privately rented homes: impact assessment', for what reason there is no specific data for Wales.
Answered by Martin McCluskey
The analysis in the impact assessment is produced using the Department’s National Buildings Model, which is based on the English Housing Survey and therefore covers England only. The results are scaled to reflect the number of dwellings in Wales, with Wales assumed to follow the overall average. Further details on the modelling approach and the National Buildings Model are set out in Annex B of the Impact Assessment.
The UK government has worked closely with the Welsh government to develop the policy.
