ESOS Energy Audits

ESOS Energy Audits

Large businesses that are required to comply with the Energy Savings Opportunity Scheme must carry out an ESOS Energy Audit every four years. An energy audit reviews the organisation’s total energy usage, including buildings, industrial processes and transport. These assessments are then used to identify cost-effective energy saving measures.

You will need to appoint an approved ESOS Lead Assessor to oversee and sign-off on the audit – they will create an ESOS Audit Summary Report and ESOS Audit Evidence Pack. The audit must also be signed off by a board-level director before it is submitted to the Environment Agency.

How can I comply?

The ESOS Energy Audit is one of the four routes to compliance identified by the Government:

  • ESOS Energy Audits
  • ISO 50001 certification
  • Display Energy Certificates (DECs)
  • Green Deal Assessments (GDAs)

The actual audit methodology can vary depending on the organisation and the agreed objectives with your Lead Assessor. As long as 90% of your total energy consumption is covered, you can use elements from other approaches to gather the relevant data and meet the requirements for compliance.

An ESOS compliant energy audit must meet these criteria:

  • It must be based on 12 months’ verifiable data
  • It must analyse the participant’s energy consumption and energy efficiency
  • It must identify energy saving opportunities

An ESOS Energy Audit is the bespoke method to compliance. The actual audit methodology can vary depending on the organisation and the agreed scope and goals of the assessment.

The ESOS Energy Audit is one of the four routes to compliance identified by the Government:
• ESOS Energy Audits;
• ISO 50001 certification;
• Display Energy Certificates (DECs); and
• Green Deal Assessments.

It is important to note that the ESOS Energy Audit can use elements of the other routes to compliance. For example, part of your ESOS Energy Audit could contain Display Energy Certificate Operational Ratings for your buildings.
