We use independent audits to provide assurance that Accredited Certificate Providers (ACPs) create energy savings certificates (ESCs) in accordance with the relevant legislation.

Your audit regime is specified in your Accreditation Notice and may include an audit of any of the following matters:

  • The creation of ESCs
  • Compliance with any conditions of accreditation
  • Compliance with the requirements of the relevant legislation governing creation of ESCs.

The audit requirements of each accreditation are based on a risk assessment, which considers the nature of the calculation method, the compliance history of the ACP (or applicant) and the proposed number of ESCs involved.

We determine your audit regime at the time of accreditation and may make risk-based adjustments to it from time to time. The Compliance Guide – ACPs explains why we may adjust your audit regime, while the Application for Accreditation Guide – ACPs explains how we set your initial audit regime.
