The Chartered Institute of Building (CIOB) has analysed three UK government housing reforms concluded in 2025. Energy Performance Certificate (EPC) reforms will introduce four headline metrics from 2026, replacing single ratings and requiring certificates at marketing stage, alongside secondary measures on delivered energy and carbon emissions, an expanded scope covering additional property types, and continued ten-year validity, with the aim of improving consumer information and aligning with Minimum Energy Efficiency Standards. The government has also established a revised Decent Homes Standard to apply to all rented housing from 2035, enforced by local authorities and the Regulator of Social Housing, requiring homes to be safe, in reasonable repair, adequately equipped, thermally comfortable and free from damp and mould, while allowing proportionate exemptions and linking thermal comfort to energy efficiency requirements. In addition, the Future Homes and Buildings Standards will take effect from March 2027, requiring new homes to be zero carbon ready through high fabric efficiency, low carbon heating systems and renewable energy generation, supported by Home User Guides and existing performance metrics with optional reporting on delivered energy. Further detail on implementation and enforcement is expected in 2026, with the reforms collectively integrating energy efficiency, safety and housing quality within a single regulatory framework.
