As part of the mandatory requirements for ESOS Phase 3 compliance, large businesses must submit their action plan alongside two progress reports. While there were initially no financial penalties for non-compliance, the Environment Agency (EA) has updated its stance—failure to meet these requirements on time can now result in fines.
Here are the key deadlines:
- Action Plan: 5th March 2025
- Progress Report 1: 5th December 2025
- Progress Report 2: 5th December 2026
You’re not required to use your current ESOS Phase 3 Lead Assessor to meet the ESOS reporting obligations. You can use alternative ESOS energy specialists, like Brownlow Utilities, giving you a the ability to review, simplify and centralise ALL of your energy, water and sustainability activities. All we need is your previous compliance report and we can have a discussion to identify your opportunities – both short and longer-term.
