ESOS energy audit
ESOS Energy Audit methodology can vary depending on the type of business to be audited and agreed objectives with the Lead Assessor.
Government guidance recommends several methodologies (see below) that can be implemented to achieve the required compliance levels.
Upon notification of compliance to the Environment Agency, the participant must be in possession of a ESOS Audit Summary Report and ESOS Audit Evidence Pack, signed off by the appointed Lead Assessor and a board level Director.
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.
ESOS legislation requires participants to:
1. Appoint a Lead Assessor
2. Measure your total energy consumption across your buildings, transport and industrial activities over a 12 month period (must include December 31st 2018).
3. Identify areas of significant consumption, accounting for at least 90% of your total consumption.
4. Conduct energy audits on areas of significant consumption and produce reports that identify cost-effective energy efficiency recommendations (based on life cycle cost analysis where possible).
5. Report compliance to the Environment Agency By 5 December 2023, You must ensure that your ESOS Assessment has been reviewed by a Board-level Director and approved by a Lead Assessor.
