ESOS MESOS Update

Energy Saving Opportunity Scheme Compliance Update - MESOS

20th March 2024

Large organisations in the UK, take note – the Energy Saving Opportunity Scheme (ESOS) has updated its compliance terms. All organisations are now required to register on the Manage Your Energy Savings Opportunity Scheme reporting system (MESOS) by the deadline of 5th June 2024, though will not need to submit their compliance documentation until 6th August 2024.

What does this mean for my organisation?

Organisations that have completed ESOS previously should have already received a notification from the Environmental Agency detailing changes, and what actions are required, but organisations new to the scheme will be required to register on the MESOS system before 5th June 2024.

Users can begin filling in their notifications of compliance in April, and the Environment Agency will be publishing additional information in the coming weeks. To help organisations comply with the new MESOS system, an extension has been granted, and they must submit proof of compliance before 6th August 2024.

What information is required?

Clients who wish to register must provide the following information:

  • Responsible undertaking name
  • Responsible undertaking registration number
  • Standard industrial classification code
  • Responsible undertaking registered address
  • Primary contact first name and surname
  • Primary contact company email address
  • Secondary contact first name and surname
  • Lead assessor first name and surname

I haven’t registered on the ESOS portal – what should I do?

We’d recommend registering as soon as possible. Simply navigate to the Environmental Agency’s website and submit your details. Need help? Our team of ESOS experts supports our help you with submission of the required pre -information and guide you through the registration process.

I’m not sure if my organisation needs to comply with ESOS.

  • 250 employees or more
  • An annual turnover greater than £44,000,000 and an annual balance sheet greater than £38,000,000
