Back to basics


What is it?
ESOS, the Energy Savings Opportunity Scheme, was introduced by the Government to promote energy efficiency. The scheme was designed to ensure large enterprises are regularly assessing their energy usage every 4 years and, most importantly, to highlight energy savings opportunities as a mandatory practice.

How long does it take?
Each ESOS audit is different, Enistic offer a free scoping meeting in order to fully understand the size and the needs of the organisation. The length of the project can vary from one another.

With over 10,000 companies needing to comply, it’s important to stay ahead of competition and begin the route to compliance early. Failure to comply in time can lead to fines of up to £50,000.

How do I know if I need to comply?
To fall into ESOS, an organisation must:

  • Have over 250 members of staff.
  • Or turnover of over 50 million Euros (£38,937,777) and an annual balance sheet total in excess of 43 million euro (£33,486,489).
  • Or be a part of a larger organisation that falls into either of these categories.


What's required?
  • 90% of energy consumed by the organisation has to be accounted for across all sites, including transport.
  • Must use 12 months’ verifiable data.
  • ESOS Assessments must be reviewed and signed off by a Board-level Director, and approved by a Lead Assessor and then reported to the Environment Agency.
  • Energy audits need to be conducted and data submitted every 4 years.
  • Failure to comply with ESOS can lead to fines of up to £50,000 and public disclosure of noncompliance.
