The Electricity and Gas (Energy Company Obligation) (Amendment, Saving and Transitional Provisions) Order 2025

This Order extends to Great Britain. Standard Assessment Procedure (“SAP”) and Reduced Data Standard Assessment Procedure (“RdSAP”) are methodologies used in both the Electricity and Gas (Energy Company Obligation) Order 2022 (“the 2022 Order”) and the Electricity and Gas (Energy Company Obligation) Order 2023 (“the 2023 Order”) to evidence the starting and finishing SAP ratings of existing domestic premises. Both SAP and RdSAP are published by the Building Research Establishment and have undergone updates. Therefore, the 2022 Order and the 2023 Order are being updated to align with the wider industry updates.
