National Fraud Initiative

The National Fraud Initiative (NFI) is a data-matching exercise that helps detect and prevent fraud and overpayments from the public purse across the UK.

The NFI matches data across organisations and systems to help public bodies identify fraud and overpayments. Since its commencement in 1996, NFI exercises have resulted in the detection and prevention of more than £30 million of fraud and overpayments in Wales and £1.3 billion across the UK.

The NFI 2014-15, resulted in the detection and prevention of overpayments worth £4.4 million.

Forty two Welsh public sector bodies took part in the exercise, including local authorities, police authorities, fire authorities, NHS bodies, the Welsh Government, Cardiff University, the Wales Audit Office and other public sector auditors.

The main findings of the report are summarised in a short video [opens in new window].

The NFI programme is successful because of its participants, the more participants involved, the greater the amount of data that can analysed for fraud and overpayments. The Code of Data Matching Practice of the Auditor General for Wales [PDF 391KB Opens in new window] was prepared to guide all those who take part in data-matching work.
