Law & Compliance

Making your Building Compliant with Energy Legislation

The Energy Savings Opportunity Scheme (ESOS) is a mandatory energy assessment scheme for organisations in the UK that meet the qualification criteria. Organisations that qualify for ESOS must carry out ESOS assessments every 4 years. These assessments are audits of the energy used by their buildings, industrial processes and transport to identify cost-effective energy saving measures.

Key points to note:

  • Captures all Non-SME’s with either:
    • more than 250 employees or
    • a turnover in excess of €50m and
    • an annual balance sheet total of €43m.
  • The Environment Agency will publish the names of any businesses that fail to comply and will issue fines appropriate to the level of non-compliance.
  • Every ESOS compliance submission must be managed by an approved ‘Lead Assessor’ and Low Carbon Alliance’s own Lead Assessors are ready to assist your business ahead of the Phase 3 deadline.
  • ESOS Phase 3 qualification date is 31st December 2022. The deadline for submitting a phase 3 notification of compliance  is 5 June 2024 (previously 5 December 2023)  Organisations that qualify for ESOS in phase 3 will be required to comply with the Energy Savings Opportunities Scheme (Amendment) Regulations 2023.
  • ESOS Phase 4 has been confirmed:
    • the compliance period will begin on 6 December 2023,
    • the qualification date is 31 December 2026, and
    • the final compliance deadline is 5 December 2027

Streamlined Energy & Carbon Reporting (SECR) came into force on April 1st 2020, and qualifying organisations are required to report on energy use and resulting carbon emissions annually via the SECR framework, this is in addition to the ESOS reporting every 4th year.

The scheme forms part of the UK Government’s Clean Growth Strategy, which calls on businesses to improve energy productivity by at least 20% by 2030.   This has effectively replaced the reporting element of the CRC Energy Efficiency Scheme.

SECR covers all large companies with:

  • more than 250 employees
  • an annual turnover of more than £36m
  • a balance sheet of £18m or more

This includes LLPs and unregistered businesses and you will be covered if you meet two out of three from the above criteria.

Firms that use less than 40,000kWh of energy across a year are exempt,

Who Qualifies?

The SECR framework applies to companies registered under the Companies Act 2006.  This means that organisations which are not registered as companies, for example, public sector organisations, some charities, and some private sector companies such as certain partnerships, may not be in the scope of the SECR framework.

What and How do I report?

You will be required to report energy use and carbon emissions for a 12 month period that can match your financial year. The results are required to be reported in the following way:

What happens if we do not comply?

There will be legal and financial implications for companies not complying. LLPs that fail to comply with the requirement to prepare an Energy and Carbon Report risk prosecution and a potential fine for all Companies House registered members of the LLP. Company secretaries from quoted companies will be liable for prosecution under the existing terms of the Companies Act.

With regards to enforcement, Companies House may not accept reports that do not meet the requirements of the Companies Act.
