"What's changing with EPCs in Scotland? Scotland is overhauling how Energy Performance Certificates (EPCs) work. The new Energy Performance of Buildings (Scotland) Regulations 2025 were laid before the Scottish Parliament on 10 October 2025. EPCs are already used to show a home's energy efficiency and carbon emissions when it's for sale, rent, or newly built. The reform will introduce: New ratings for energy efficiency and heat retention. Redesigned EPCs and Property Reports with clearer guidance for homeowners and tenants."
"While EPCs exist across the UK, Scotland is taking a slightly different path: Heat Retention Rating: A new metric for homes, replacing or enhancing some older energy ratings. Calculation methods: Scotland is using new models (the Home Energy Model for domestic buildings and the Simplified Building Energy Model for non-domestic buildings) that differ from current UK methods. Property Reports: More detailed advice for homeowners on potential improvements, like insulation or heating upgrades."
New regulations, effective 31 October 2026, redesign Energy Performance Certificates and Property Reports, add new ratings, and upgrade digital systems to support energy savings and emissions reductions. The Energy Performance of Buildings (Scotland) Regulations 2025, laid on 10 October 2025, introduce a Heat Retention Rating and new calculation models: the Home Energy Model for domestic buildings and the Simplified Building Energy Model for non-domestic buildings. Property Reports will give more detailed retrofit advice such as insulation and heating upgrades. A new cloud-based EPC Register will issue and store certificates under a Scotland-specific digital system. The Scottish approach diverges from other UK systems while retaining some alignment for the assessor market.
