DWP has robust control and assurance arrangements in place to guard against fraudulent claims being made by providers. Before payment, every job outcome claim is checked to ensure that the programme participant has left benefit. A sample of claims is further checked to ensure that the participant has not only left benefit but is also in employment. In addition, the Department requires all providers to have robust and effective controls in place to mitigate the risk of internal manipulation, and to operate whistleblower facilities to enable staff to report any concerns. Programme providers are regularly inspected to ensure that their internal processes and controls are operating effectively. Errors can and do occur in the claims process for legitimate reasons, and the Department will recover any monies paid in these circumstances. However where the Department identifies, or are notified of, allegations of contractor fraud, these cases are investigated thoroughly by DWP's professionally trained and experienced investigators.
