Master the ESOS Action Plan

The Energy Savings Opportunity Scheme (ESOS) is a compulsory energy assessment programme for eligible organisations in the UK.


Managed by the Environment Agency, ESOS mandates that qualifying organisations evaluate their energy consumption every four years. This includes conducting audits of energy usage in buildings, industrial processes, and transportation.


Phase 4 is currently in progress, with the initial reporting deadline set for 5th December 2024—just six months following the Phase 3 reporting deadline.


In contrast to previous ESOS phases, which only required one compliance submission every four years, businesses must now submit an annual progress report to the Environment Agency (EA). The organisation in charge is also required to establish an action plan outlining future energy-saving initiatives.
