Energy Savings Opportunity Scheme (ESOS)

Ensure compliance with the creation of an energy audit and consumption report to meet the UK Legislation.

Professional Energy Services can help your organisation ensures ESOS Compliance.

Our energy consultants have a wealth of industry experience in carbon compliance and coupled with our energy management software, we can perform the required energy audits to generate a consumption report and act as the required lead Assessor for ESOS compliance.

What is ESOS?

The Energy Savings Opportunity Scheme (ESOS) is a UK energy legislation for meeting the EU Energy Efficiency Directive Article 8. ESOS came into force on 17 July 2014.

ESOS is a mandatory compliance scheme for large organisations that met qualifying criteria with the goal of reducing EU energy consumption by 20% by 2020. ESOS compliance occurs every 4 years in four yearly phases and requires regular energy audits that help large businesses conserve energy. We are currently in ESOS Phase 3.

Does my Organisation Need to comply to ESOS?

The criteria for ESOS compliance are for large organisations that met the following:

  • More than 250 employees or
  • A turnover of more than €50,000,000 and an annual balance sheet total of more than €43,000,000

Organisations include corporate bodies and partnerships, and any unincorporated body that is conducting trade whether for profit or otherwise, are all subject to ESOS.

Public sector organisations are not subject to ESOS, although some universities with significant private funding may well be.

What does ESOS Require?

ESOS compliance requires the production an energy audit of the entire operation’s energy consumption for the four year period. The first report for ESOS Phase 3 must be lodged with the Environment Agency by 5 December 2023.

The required energy audit must cover 90% of your organisations energy and be reviewed and approved by a qualified ESOS Lead Assessor. To aid your ESOS Compliance we recommend you also gain:

  • Display Energy Certificates (DECs)
  • Green Deal Energy Assessments
  • ISO 5001 certification

Avoid Serious Penalties

The Environment Agency (EA) will not hesitate to impose penalties for organisations who are mandated to comply with ESOS but did not participate or failed to meet the required standards. For each separate breach of the ESOS regulations expect the following penalties:

  • Failure to notify: £5,000 plus £500 for each working day an organisation remains in violation regardless of whether the organisation has undertaken an energy audit.
  • Failure to maintain records: £5,000, plus a “sum representing the cost to the compliance body of confirming that the responsible undertaking has compliance complied with the scheme,” which must be resolved.
  • Failure to undertake an energy audit: £50,000 plus £500 for each working day an organisation remains in violation. There is more leniency for new entrants with a reduced of £5,000.
  • Failure to comply with an enforcement/penalty notice: £5,000 plus £500 for each working day an organisation remains in violation
  • False or misleading statement: £50,000.
  • Non compliance being made public: the name of your organisation and the amount you were fined will be published on the EA to website.

Frequently Asked Questions on ESOS

Is ESOS a carbon tax?

No. ESOS helps to discover energy inefficiencies and waste with the goal of ensuring businesses to change behaviour to reduce energy consumption. It is not a direct tax on CO2 emissions.

Is the Public Sector affected by ESOS?
ESOS largely excludes the public sector such as institutions which must adhere to the 2006 UK Public Contracts Regulations (England, Wales, and Scotland). Universities with significant private funding may be required to perform ESOS.
What if my organisation is part of a group?

A smaller “undertaking” or organisation shall not be excluded from ESOS participation if it is part of a larger organisation containing at least one qualifying “large undertaking.”

For corporate groups that participate in ESOS, the highest UK level of that entity will be responsible for ensuring the group as a whole is ESOS compliant.

Does all of my organisation’s energy consumption need to be audited?
An accurate ESOS assessment requires an evaluation of 90% of an eligible organisations’s total energy usage. This figure can be presented in a number of ways, whether by fuel type, site, organisation, etc., provided that a fair approach is used for analysis. The energy you are choosing to exclude is referred to as your ‘de minimis energy consumption.’
What types of transport energy consumption are included in ESOS?
ESOS includes transport energy usage only where the organisation has purchased the fuel directly and claiming on the cost of fuel. Therefore, company travel by rail or air is excluded, but company cars would be included where employees claim the cost of fuel from their employer.
How is ESOS Implemented?
A lead assessor will conduct an energy audit by reviewing your organisation’s energy data over the course of the relevant 12 month ESOS phase period. Your sites will be surveyed using energy consumption profiling (typically energy management and consumption software), to understand where energy is used and wasted. This generates a report that your lead assessor will use to create a plan for compliance with strategies to reduce energy consumption.
How Can I Reduce My ESOS Costs?

There are two ways to decide how to perform ESOS with their own costs of either:

  • In-house – performing the energy audit and obtaining an approved lead assessor certification via a professional registered body.
  • Outsourcing – working with an energy consultant like PES

Both of these methods have their own costs, outsourcing may have a higher cost but comes with the security of knowing an expert will be efficient and able to create the task correctly. Conducting ESOS in-house may be cheaper but comes with more complications of gaining approval of your lead assessor from the registered bodies and also your own team may be more prone to errors as not as experienced as a consultant and the cost of your own time to conduct your ESOS assessment.

However, regardless of cost if your organisation follows the energy-saving recommendations that an audit brings, your cost reductions on your energy bill will likely outweigh the cost of performing ESOS. The UK government has estimated organisations performing ESOS could save 13.5 times the actual cost of the energy audit.

When is the next ESOS deadline?
We are currently in phase 3 of ESOS compliance with a deadline of 5th December 2023.
How often do I need to perform ESOS?

An ESOS assessment must be conducted every 4 years and we are now in phase 3 of the four yearly cycle.

The original timeframes of the ESOS are in the table below when the scheme was launched in 17 July 2014.

Who regulates ESOS?

Though the Environment Agency administers the scheme for the entire UK, it only regulates the scheme in England. For other UK territories, other bodies are responsible for overseeing regulation. For example, the Scottish Environment Protection Agency, Northern Ireland Environment Agency, and Natural Resources Wales regulate ESOS separately.

Offshore, the Secretary of State for Business, Energy and Industrial Strategy regulates ESOS.

Can anyone in my organisation conduct the ESOS assessment?

No. An approved Lead Assessor should oversee the ESOS process. Approval comes from gaining membership by an approved professional body register. An in-house employee will either need to apply to qualify for this role, or a company will need to work with an external consultant.

Will details of my company’s energy use be made public?

No, an organisations’s ESOS report will not be made public.

Will I be fined if I don’t implement energy-savings recommendations?

No, penalty fees do not apply if an organisation fails to implement recommendations. Only the assessment itself is mandatory. However, implementing the energy consumption reducing strategies in place will reduce your energy spent and help an organisation recoup the cost of the ESOS assessment.

How does ESOS apply if I supply energy to another organisation?

ESOS participants are responsible for all energy they consume, but not for energy that they supply to a separate third party such as a tenants renting part of a site/property that is metered. However, the landlord would be responsible for energy usage in common shared areas of a building.

Does every site need to be surveyed for ESOS?
No, If your organisation has similar sites then a few sample sites can be surveyed and the finding used for the other similar sites.
Will the current ESOS standards change?

Potentially. The government is currently working on several changes that will strengthen the ESOS scheme, including requiring organisations to publicly disclose their ESOS data and carry out a net zero assessment. These changes are still in consultation after the chance to provide feedback closed in September 2021.

How does my participation in other energy legislation affect my ESOS compliance?

You still need to comply to ESOS but you can potentially be efficient with the data from the energy audit and consumption report and reuse it for other carbon compliance schemes such as Streamlined Energy and Carbon Reporting (SECR).

Do I need to perform ESOS if I’m already ISO 50001 certified?

You do not need to perform ESOS if your organisation is covered by ISO 50001 but ensure you submit a notification to the regulator.
