ESOS – What is it?

ESOS is the UK Government's mandatory legislation in response to implementing Article 8 of the EU Energy Efficiency Directive.

The Regulating Body is the Environment Agency. 

For full Environment Agency Guidance please visit the site and download the "Complying with the Energy Savings Opportunity Scheme" document.


Does it affect me?

ESOS applies to you if any Company within your UK Group of companies has:

More than 250 employees


An annual turnover of €50m and a balance sheet exceeding €43m


What do you have to do?

  • Identify your full Organisation energy usage: gas, electricity, oil, any other fuels and transport.
  • Undertake appropriate energy audits to identify opportunities to save costs.
  • By the 5th December 2015 you needed to confirm compliance to the Environment Agency.
  • This is repeated on a 4 yearly cycle.
  • If you qualify but have missed the compliance deadline above, you must notify the Environment Agency.
