Update on the Energy Savings Opportunity Scheme (ESOS)
 Energy Savings Opportunity Scheme amending regulations from 2024
ESOS is a mandatory energy assessment scheme for qualifying UK organisations (those defined as ‘large undertakings’) and administered by the Environment Agency (EA). New ESOS Amending Regulations have just been issued, which are set to become effective by the end of 2023.
 ESOS Requirements and deadlines
Organisations that qualify for inclusion in ESOS must carry out ESOS assessments every four years. These audits - of energy use in buildings, processes and transport – should identify applicable, cost-effective measures to save energy and thus achieve cost/carbon savings. ESOS is now entering its third compliance period (‘phase 3’). Organisations that qualify for ESOS must meet the requirements of the new Amending Regulations and, for phase 3, must notify the EA by 5 June 2024 that they have complied with their ESOS obligations;
According to ECA Director of CSR Paul Reeve “Following requests from industry stakeholders, to help provide a sensible timeline for participants to meet the newly amended legislative requirements (and for assessors to carry out ESOS assessments) phase 3 participants have until 5 June 2024 to provide their notification of compliance – a six months extension from the previously expected (and now imminent) date of 5 December”.
 New Amending Regulations
The Energy Savings Opportunity Scheme Regulations 2014 were amended on 27 November 2023 by the Energy Savings Opportunity Scheme (Amendment) Regulations 2023 (SI 1182) (the ESOS Amendment Regulations). These Amending Regulations introduce changes to ESOS that aim to make the scheme more effective. The new Regulations are at: www.legislation.gov.uk/uksi/2023/1182/note/made
EA guidance also shows/signposts to what is required to achieve and notify ESOS compliance at: www.gov.uk/guidance/energy-savings-opportunity-scheme-esos
