What is ESOS?

The Energy Savings Opportunity Scheme (ESOS) is a mandatory government scheme that requires large businesses to identify energy-saving opportunities and report on least 90%* of their energy usage to the Environment Agency.

*Subject to change in either Phase 3 or ESOS Phase 4

What is the purpose of ESOS?

ESOS gives organisations the opportunity to conduct a review of their energy use and identify ways to improve energy efficiency. This allows businesses to reduce their usage and costs whilst helping to tackle climate change. Our reporting structure provides carbon savings along with energy reductions, meaning that your ESOS project can act as a means to start a carbon reduction initiative, within your organisation.

Who needs to comply with ESOS Phase 3?

Your business needs to comply with ESOS if, on 31 December 2022, it met the definition of a large business as follows:

  • Employs 250 or more people, or
  • Has an annual turnover in excess of £44m and an annual balance sheet total in excess of £38m, or
  • Is an overseas company with a UK registered establishment which has 250 or more UK employees (paying income tax in the UK)

When is the ESOS phase 3 deadline and what happens if my business does not comply in time?

ESOS runs in four-year phases and we are currently in Phase 3 of the scheme. The deadline for phase 3 is 6 August 2024. Fines can be levied by the Environment Agency for failure to meet the submission deadline. These are likely to be more severe for firms who have been involved with previous phases of ESOS, and did not meet the deadlines for that phase.

What is an ESOS Lead Assessor?

An ESOS Lead Assessor is someone who meets the approval criteria set out by the Government and is therefore qualified to sign off ESOS reports and projects.

All of our ESOS reports are completed inhouse by our team of experienced and qualified Lead Assessors. Our Lead Assessors have assisted over 100 clients in the previous phase ESOS, in complying with the scheme.

How can Earth Hub help with ESOS?

There are a number of routes to ESOS compliance. Earth Hub provides compliance via the Energy Audit route, and we will support you through every stage of the process.  

Delivery of our ESOS projects includes:

  • An onboarding call to introduce our team and get to know more about your business
  • Gathering the necessary energy consumption data of your organisation
  • Identifying sites and /or transport activities required for an Energy Audit at a convenient time/date for you
  • Conducting full ESOS compliant energy audits of applicable sites (completed to BS EN16247 standards for energy auditing)
  • Providing a detailed report on your business’s energy consumption including costed recommendations for improved energy efficiency.
  • Report sign off by our Lead Assessor (signature also required by your organisation’s Director)
  • Compliance submission to the Environment agency

What happens after my business is ESOS compliant?

We can support you to implement the energy efficiency recommendation projects outlined within your Energy Audit reports, and provide tailored advice on reducing your business greenhouse gas emissions and a net zero strategy. We also manage your ESOS evidence pack and provide support should you be called to submit this to the Environment Agency.
