The quality of changes made has met expectations

2.2  Before any payment is made for a change, public sector contract managers check to ensure that work has been completed to an agreed standard. Around 90 per cent of contract managers responding to our survey were satisfied or very satisfied with the quality of work done to implement change requests (Figure 6). PFI contractors have an incentive to minimise the risk of a poorly executed job impacting on core elements of service provision. If, for instance, additional wiring was faulty and resulted in a whole room becoming unavailable, the SPV could face a reduction to the unitary charge. We did not find any examples of the public sector refusing to pay for work on the basis that it was not completed to a sufficient standard or had not been rectified when brought to the attention of the contractor involved.
