Scheme participant compliance timeline

See below the compliance timeline for the 2025 Energy Savings Scheme (ESS) and 2025-26 Peak Demand Reduction Scheme (PDRS) compliance periods. This includes key dates you must meet as a scheme participant in line with your obligations.

We will maintain a similar compliance timeline for the 2026 ESS and 2026-27 PDRS compliance periods. 

The Compliance Guide - Scheme Participants provides guidance on how to comply with key reporting deadlines.
