ESOS Compliance

We’re here to help you on your journey to compliance with the Energy Savings Opportunity Scheme (ESOS).

What is ESOS?

The Energy Savings Opportunity Scheme (ESOS) is a mandatory compliance scheme in the UK, derived from Article 8 of the EU Energy Efficiency Directive. ESOS aims to reduce EU energy consumption by 20% by 2020. ESOS occurs in four-yearly phases and introduces regular energy audits that highlight energy savings for large businesses.

These audits must cover 90% of your organisational energy and require sign-off from a qualified ESOS Lead Assessor. Routes to compliance include ESOS audits, Display Energy Certificates (DECs), Green Deal energy assessments and ISO 50001 certification.

Who needs to comply with ESOS?

Public bodies are not affected. Large organisations that must comply are classified as those with:

  • 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


Savvy businesses can save time and hassle by using our exclusive compliance package. As well as saving you time and hassle we also offer you a 10% discount if you sign up for a joint 5 year ESOS and Streamlined Energy and Carbon Reporting (SECR) package.
