Energy Savings Opportunity Scheme

Our Qualified Lead Assessors can help you with ESOS compliance

The Energy Savings Opportunity Scheme (ESOS) is a mandatory UK government designed to reduce large private sector organisations energy consumption and carbon emissions.


What is the Energy Savings Opportunity Scheme (ESOS)?

  • ESOS Phase 1 was launched in 2011 as the implementation an EU directive.
  • Qualifying companies have a four-year window in which to comply.
  • The criteria changes for each phase.
  • It is a legal requirement for qualifying organisation and they must demonstrate they have assessed their energy use and identified whether energy-savings improvements can be made.
  • ESOS is all about identifying energy efficiency measures that would result in significant reduction in energy consumption, carbon emissions, and energy cost savings.
  • It is an opportunity to strategically assess your energy management policies and make positive changes to the way your business uses energy.

Does the scheme apply to your company?

A large private organisation is defined as having:

  • At least 250 employees OR an annual turnover of more than £44 million
  • An annual balance sheet total in excess of £38 million

If your company meets these criteria on the 31 December 2022, then you must complete an ESOS Phase 3 assessment.

What are the penalties for non compliance?

Your environmental regulator is responsible for compliance and enforcement activities. The regulator may issue civil sanctions including financial penalties if your organisation doesn’t meet the ESOS obligations.

When is the ESOS Phase 3 deadline?

ESOS phase 3 has already begun. The deadline has been extended to 5 June 2024 (previously 5 December 2023).

Although the deadline has been extended, don't delay and start working on your energy audits and identification of energy savings opportunities now.
