DESNZ publishes 2025 post implementation review of Energy Savings Opportunity Scheme
The Department for Energy Security and Net Zero (DESNZ) has published its 2025 post implementation review (PIR) of the Energy Savings Opportunity Scheme (ESOS) Regulations 2014, SI 2014/1643. The review draws on the Phase 3 notification of compliance data from the Environment Agency, as well as unpublished interim data from Phase 3 action plans and follows the 2020 PIR. It recommends that no major changes be made to SI 2014/1643 until the conclusion of a full evaluation of the scheme in May 2026, after which a comprehensive PIR will be completed. The research aims to evaluate the effectiveness of energy audits and reporting in identifying and delivering energy efficiency savings across organisations.
