Energy Savings Opportunity Scheme (ESOS) – 19th March 2024


MESOS Reporting System 

The Manage your Energy Savings Opportunity Scheme reporting system (MESOS) has now gone live. As detailed in our previous briefing note, MESOS will be released in two stages, with an initial release allowing all participants to register their Phase 3 user and organisational accounts, and a further release allowing participants to start filling in their notifications of compliance planned for the second half of April 2024.

The Environment Agency will confirm the exact date of the second release by the end of March 2024 and will host a webinar to support this release in early April 2024.

Compliance Notification Enforcement Extension Position Statement 

With the new IT system going live and the requirement of a two-stage compliance notification process, the Environment Agency have taken steps to help participants complete compliance in a timely manner by providing this position statement.

For organisations qualifying for Phase 3 of ESOS, the deadline for submitting a compliance notification is the 5th June 2024 and organisations should still look to meet this compliance notification deadline where possible.

However, the Environment Agency will not take enforcement action against you if you do not comply with this legal requirement provided that you meet both of the following conditions:

  • Registration of your account in the new IT system has been completed by the 5th June 2024 
  • You submit your notification of compliance by the 6th August 2024 

This regulatory enforcement extension period will cease after the 6th August 2024.
