Find out all you need to know about ESOS and the services LGE offer below

Established by the then Department of Energy & Climate Change, the Energy Savings Opportunity Scheme (ESOS) is a mandatory scheme which targets large UK businesses and is designed to increase engagement with energy management systems and reduce consumption. However, the benefits for smaller businesses are also numerous. ESOS is now in its third phase which started on 6th December 2019 and each phase runs for four years, subsequently the deadline of 5th June 2024 for phase three is fast approaching.

Participants must report on all energy consumption through buildings, industrial processes and transport over a 12-month period within certain deadlines. Reporting must be in line with ESOS standards and approved by a lead ESOS assessor. UK businesses which must partake have been defined as:

  • 250 employees or more
  • Has less than 250 employees but a turnover of more than £44 million and a balance sheet more than £38 million

Penalties for non-compliance include a variety of measures:

  • £50,000 fixed penalty for failure to conduct an ESOS assessment

  2. Survey- Examines metering equipment and where energy is consumed, reviews general energy management policies and potential improvements to building fabric, studies existing heating arrangements, appraises existing energy controls and audits electricity usage
  3. Post-Survey- An ESOS compliant report will be provided to examine all energy saving options, with clear recommendations on a spreadsheet which are divided into low-cost and medium-high cost energy saving measures
