Energy Savings Opportunity Scheme (ESOS) compliance

ESOS Action Plan Progress Update support

Action Plan Progress Updates are new to ESOS, and require you to report on Action Plan implementation by 5th December 2025. You’ll need to confirm:

What progress you’ve made on Action Plan measures
If you’ve implemented any new measures
What energy consumption reductions you’ve achieved

Need advice? Concept’s accredited ESOS lead assessors can help you get started. Get in touch.

ESOS Phase 4 compliance

The compliance period for ESOS Phase 4 started on 6th December 2023, so you can start preparing now, ahead of the 5th December 2027 deadline.

Progress against Action Plan commitments must be included in the ESOS assessment, and organisations will be required to provide explanations if Action Plan commitments have not been met. Read more about what’s happening in ESOS Phase 4 and 5.

We can help you prepare for Phase 4, so get in touch for advice.

Missed the ESOS Phase 3 deadline? Act now to avoid enforcement action

The deadline for ESOS Phase 3 passed on 6 August, and the Environment Agency is now contacting non-compliant organisations.

Our qualified ESOS Lead Assessors are supporting organisations with late submissions, and we may be able to help you minimise the penalty cost.

We’ll also use the report findings to create a roadmap that will significantly reduce your energy consumption, both now and in the long run.
