Scheme
(ESOS)

What is ESOS?

ESOS is an energy auditing and assessment scheme introduced by the UK government, to encourage large undertakings in the UK to focus on being more energy efficient. Phase 3 of the ESOS has just concluded and we are now in Phase 4 which runs until 2027.  

ESOS is mandatory for any UK company that either employs 250 or more employees; or has an annual turnover of £44 million or more and an annual balance sheet total in excess of £38 million.  If your company qualifies, it must undertake an energy assessment and audit every four years and identify ways to save energy, with the next compliance deadline of 5 December 2027. 

Phase 3 has seen the introduction of action plans, which qualifying companies must submit by 5 March 2025, with annual progress updates then required in 2025 and 2026.

What happens if we
don't comply?

The ESOS Phase 3 compliance deadline was 5 June 2024.  For Phase 4 the deadline is 5 December 2027, with the qualification date set at 31 December 2026. 

Failing to comply, maintain records, or notify of ESOS compliance by the deadline can result in civil sanctions and hefty fixed penalty fines of up to £50,000 being issued by the Environment Agency. You company’s details are also published online which does not promote your business in a positive light.
