We will ensure your sustainability audit and report is created in accordance with the International Standard on Assurance Engagements (ISAE) 3000. The Renewables Obligation specifies points that must be addressed as part of the audit process which include the need for the auditor to consider:

Whether the systems used to produce the relevant sustainability information are likely to produce information that is reasonably accurate and reliable

Whether there are controls in place to help protect the relevant sustainability information against material misstatements due to fraud or error

The frequency and methodology of any sampling carried out for the purpose of obtaining or checking the data on which the operator relied in preparing the relevant sustainability information

The robustness of the data on which the relevant sustainability information was produced
