About

Ofgem is seeking an audit contractor to perform technical site audits for the Non-Domestic Renewable Heat Incentive (NDRHI) and the Green Gas Support Scheme (GGSS). The contractor will check the accuracy of data provided to Ofgem, including data in reports; secure assurance of compliance with Ofgem’s published guidance and any procedures or schemes agreed with participants; detect non-compliance and fraud by auditees or their contractors; and identify departures from good practice that have resulted, or may result, in incorrect information being supplied to Ofgem. The successful tenderer must fully understand NDRHI and GGSS requirements and apply mechanical services expertise during site visits to determine whether installations or participants are complying with the relevant legislation.
