Energy Savings Opportunity Scheme

If your organisation is fully covered by ISO 50001, you don’t need to carry out an ESOS assessment.

The Energy Savings Opportunity Scheme (ESOS) applies to large UK undertakings and requires organisations to audit their energy usage and identify energy saving measures. A large undertaking is:

  • any UK company that either:

- employs 250 or more people, or

- has an annual turnover in excess of 50 million euro (£38,937,777), and an annual balance sheet total in excess of 43 million euro (£33,486,489)

  •  an overseas company with a UK registered establishment which has 250 or more UK employees (paying income tax in the UK)

Businesses must take part in ESOS if the undertaking is part of a corporate group which includes another UK undertaking or UK establishment which meets these criteria.

Where a corporate group participates in ESOS, unless otherwise agreed, the highest UK parent will act as a ‘responsible undertaking’ and be responsible for ensuring the group as a whole complies

Organisations that qualify for ESOS must carry out ESOS assessments every 4 years. These assessments are audits of the energy used by their buildings, industrial processes and transport to identify cost-effective energy saving measures.

If you qualify for ESOS and your organisation is fully covered by ISO 50001, you don’t need to carry out an ESOS assessment. Find out more about ISO50001.
