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.
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.
ESOS applies to large UK undertakings and their corporate groups. A large undertaking is defined as:
- 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)
The deadline for compliance with Phase One of ESOS was 5th December 2015. Phase 2 is now underway and the deadline is 5th December 2019.
