Understanding the Energy Savings Opportunity Scheme (ESOS)

The Government’s Energy Savings Opportunity Scheme (ESOS) is a mandatory energy assessment scheme (for qualifying companies), which aims to make UK businesses more energy efficient.

If your business meets the qualifying criteria, then you need to report on your energy use every four years – and look for cost-saving ways to reduce consumption.

ESOS is currently in phase 3, and the deadline to submit energy assessments is 5 December 2023.

Which businesses have to take part in ESOS?

An ESOS phase 3 energy audit is mandatory for UK and overseas companies that meet the following criteria on 31 December 2022:

  • More than 250 employees in the UK; or
  • A turnover exceeding £44.1m AND a balance sheet exceeding £37.9m; or
  • A parent company that meets either of the measures above

What's involved in an ESOS audit?

An ESOS audit measures your total energy usage across your buildings, processes and transport. It also pinpoints your highest consumption areas, helping you locate opportunities to save cost and energy.

The assessment will include:

  • Calculating your company’s overall energy consumption
  • Identifying and auditing areas of significant energy consumption
  • Creating an ESOS compliance plan
  • Appointing an ESOS lead assessor to review your report
  • Notifying the Environment Agency
  • Keeping accurate compliance records

ESOS: Your questions, answered

What are the key dates and deadlines for ESOS reporting?

The date for assessing whether you qualify for phase 3 of ESOS is 31 December 2022.

If your company meets the following criteria on 31 December 2022, then you must participate.

  • Your business has more than 250 employees in the UK; or
  • A turnover exceeding £44.1m AND a balance sheet exceeding £37.9m

Whole corporate groups also qualify if at least one UK group company meets these measures.

The deadline for complying with ESOS phase 3 is 23 December 2023.

You must submit your notification of compliance by that date – but it pays to begin your assessment now.

What parts of my business should be covered in the ESOS energy audit?

To calculate your organisation’s total energy consumption, you’re required to measure all energy use across your buildings, industrial processes and transport.

From there, you must audit the areas that account for 90% of your overall energy. You’re allowed to class 10% of your energy consumption as ‘de minimis’ and omit it from your report.

Your assessment should cover a representative sample of your operations and sites, and results should be presented in a common unit, such as pounds sterling or kilowatt-hours.

Are there penalties for ESOS non-compliance?

Yes, and they’ve become much tougher in recent years.

Failure to notify the Environment Agency can lead to an initial penalty of up to £5,000 and a daily fine of up to £500 until you comply – even if you’ve carried out your audits.

Making a false or misleading statement could lead to fees of up to £50,000.

When should my company begin its ESOS audit?

It’s wise to start your assessment well ahead of the 5 December 2023 deadline.

In previous phases, companies who put off their audit faced bottlenecks, delays and a shortage of lead assessors, risking harsh non-compliance penalties.

Early ESOS reporting lets you lock in compliance, spread the cost of energy-saving initiatives and realise their benefits sooner, rather than later.
