New Energy Performance Certificate Rating System Proposed for Scotland

The Scottish Government has proposed significant changes to the Energy Performance Certificate (EPC) system to improve transparency and align with efforts to reduce emissions from homes and buildings. Key changes include the introduction of a new EPC rating system that will provide clearer information on a property’s energy efficiency, heating system emissions, efficiency, running costs, and overall energy costs. The new EPC format will be easier to understand, and the validity of certificates will be reduced from 10 to 5 years to ensure more up-to-date information. The revised system is expected to be implemented by 2026, subject to parliamentary approval.
Additional proposals include the development of a dynamic EPC user interface, strengthened operational governance for assessors, and the introduction of a new calculation methodology (UK Home Energy Model) to replace the Standard Assessment Procedure. A consultation on the level of EPC lodgement fees will follow. Experts from industry have expressed support for the changes, noting the improvements in clarity, energy performance metrics, and alignment with energy standards across the UK. The new system is also expected to provide better comparison between non-domestic buildings, making it easier to evaluate their energy efficiency.
