By 2026 new tenancies must have an Energy Performance Certificate (EPC) rating of C or better, and all tenancies by 2028. EPCs are also required when properties are built or sold.
The heata unit is expected to improve the EPC rating by 4-8 points. Heata is undertaking the Standard Assessment Procedure (SAP) to trial the units and calculate the improved energy performance. The Building Research Establishment (BRE) will then add the heata unit to its database of products used to calculate EPCs.
