What is ESOS?

ESOS (the Energy Savings Opportunity Scheme) is a mandatory energy assessment scheme for organisations in the UK that meet the qualification criteria.

ESOS requires companies to carry out audits of the energy used by their buildings, industrial processes and transport every 4 years, to identify cost-effective energy-saving measures.

Who qualifies for ESOS?

  • Employs 250 people or more, or
  • Has an annual turnover in excess of €50 million (approx £40m), and an annual balance sheet total in excess of €43 million (approx £35m)
  • An overseas company with a UK registered establishment which has 250 or more UK employees (paying income tax in the UK).
