In November 2023 Which? released the Priority Places for Insulation Index which shows places around the UK which are most in need of insulation.

In partnership with Which? the Priority Places for Insulation Index data is now available to researchers via CDRC Data.

The index is novel because it incorporates both aspects of housing stock and household circumstances which exacerbate the need for insulation.

It is a composite index which considers the condition of properties in each area, as well as features of the local population including age, level of fuel poverty, and health conditions.

The index ranks geographical areas within each nation of the UK across eight different indicators relating to insulation needs and is produced by weighting and combining the eight indicators to construct an overall ranking of Priority Places for Insulation within each nation. It has been produced at three levels: local authorities, parliamentary constituencies and small local areas.

It was constructed using open data and web-scraped data from the publicly accessible Energy Performance Certificate (EPC) register for Northern Ireland as well as relevant sites where installers can be found or listed.
