The Energy Savings Opportunity Scheme (ESOS)


Organisations must take part in ESOS if on 31 December 2014 they, or at least one of their group members, were a 'large undertaking'.

A 'large undertaking' is an organisation which:

  • is registered in the UK and employs at least 250 people; or
  • is registered in the UK and has an annual turnover above €50 million (£38,937,777) and an annual balance sheet total above €43 million (£33,486,489); or
  • is an overseas company with a UK registered establishment which has 250 or more UK employees (paying income tax in the UK)

ESOS does not apply to the public sector or organisations subject to an insolvency procedure.

The ESOS assessment must cover all UK operations over a twelve month period including 31st December 2014. The assessment must include the following steps:

  • Appoint a ‘Lead Energy Assessor’ to oversee the ESOS Assessment
  • Measure the total energy consumption for buildings, industrial processes and transport
  • Identify areas of significant energy consumption that account for at least 90% of total energy consumption
  • Identify practical energy efficiency recommendations for areas of significant energy consumption and assess and report on the cost-effectiveness of each (based on a life-cycle cost analysis where practical)
  • Report compliance to the Environment Agency1 by December 5th 2015, after having had the ESOS Assessment reviewed by a Board-level Director (or senior manager where no Directors exist) and approved by a Lead Energy Assessor

As a minimum, energy assessments need to use 12 months of energy consumption data and produce practical recommendations for the area being assessed, or confirm that there is no scope for cost-effective energy efficiency improvement.

EKM Energy has helped six companies achieve ESOS compliance, through delivering energy audits and acting as Lead Assessor. These companies include an industrial gases manufacturer, an agrochemical supplier, a grain distillery, an edible oil refiner, a structural steel manufacturer and a retail distribution company. These companies are now able to plan for future-proofing their ESOS strategy and have an energy plan that will deliver cost savings over the next compliance period.

  • Have you reported compliance?


  • If so, you will have a list of opportunities. Don't let them wither on the vine - they will save energy, carbon and costs.


  • ESOS is not a once in four years event like the Olympics. Keep on top of your energy plan and you will find compliance much easier in 4 years time.


  • Contact EKM Energy now for support with implementing your energy plan and make sure that you future-proof ESOS compliance for 2019.
