NDRHI & GGSS Statistical and Targeted Audits
Authority: Ofgem (Public body)
What is being bought
Published requirement descriptionThis procurement is for the provision of an audit contractor to perform technical site audits as part of the Non-Domestic Renewable Heat Incentives programme and the Green Gas Support Scheme on behalf of Ofgem. The overarching requirements of the audit site visit, regardless of Scheme, include the successful tenderer’s auditors to:
- Check the accuracy of data provided to Ofgem. This includes data provided in any reports;
- Securing assurance of compliance with Ofgem’s published guidance and with any procedures or Scheme that Ofgem may have agreed with the participant;
- Detecting non-compliance and fraud, either on the part of the Auditee or those parties with whom they have a contract for delivering their obligations; and
- Detecting departures from good practice that have resulted, or that may result in the incorrect supply of information to Ofgem. The successful tenderer will be expected to have a full understanding of the NDRHI and GGSS requirements and expect that they can apply their mechanical services expertise during site visits to understand when installations or participants are not complying with the relevant legislation.
