ESOS Phase 1

The ESOS Phase 1 compliance deadline has passed.

If you still need to comply we can help.

ESOS compliance enforcement notices

The Energy Savings Opportunity Scheme (ESOS) is a mandatory compliance scheme in the UK, derived from Article 8 of the EU Energy Efficiency Directive.

ESOS Phase 1 compliance

Have you put off ESOS compliance for so long that now you’re worried about the consequences?

The ESOS Phase 1 compliance deadline passed in December 2015. Even so, many companies are still yet to comply.

If you qualify for ESOS Phase 1 and haven’t yet taken action, the Environment Agency (EA) will have been in touch with you.


It’s likely you’ve received a compliance note or Enforcement Notice from the EA. At December 2017, the EA has brought 240 companies into compliance via this method.

In the ultimate worst-case scenario, non-compliant companies face up to a £90,000 fine, injunctions, civil actions or prosecution. Those who have received a fine will still need to comply with ESOS.
