National data matching exercise 2016/17

By law, South Gloucestershire Council is required to protect the public funds we administer. This includes sharing information provided to us with other bodies responsible for auditing or administering public funds in order to prevent and detect fraud. As such, each year we participate in the Cabinet Office’s anti-fraud initiative, known as the National Fraud Initiative.

As part of this initiative, we are required to share personal details previously provided to us so that they can be compared to information provided by other public bodies. This will ensure that payments are only being made to those who are entitled to receive them.

If you have any queries about this process, please contact

Fair Processing-Level 3 full text

Those taking part in the National Fraud Initiative must tell individuals that their data is being processed. Providing this information is known as a fair processing notice: this gives the full text.

Please note: a minor amendment has been made to one sentence of the full text as it is produced on this page, but not as it appears in the Code. The amendment is to the second paragraph (below) and is shown below in square brackets:

Where a match is found it [may] indicate that there is an inconsistency that requires further investigation.

This amendment was made to align the full text more fully with the relevant text in the Code, which states at paragraph 2.2.2. that:

Where a match is found, it indicates that there may be an inconsistency that requires further investigation.


The Cabinet Office conducts data matching exercises to assist in the prevention and detection of fraud. This is one of the ways in which the Minister for the Cabinet Office takes responsibility within government for public sector efficiency and reform. The Minister for the Cabinet Office is also the Chair of the Fraud, Error and Debt Taskforce, the strategic decision-making body for all fraud and error, debt and grant efficiency initiatives across government.

Data matching involves comparing sets of data, such as the payroll or benefits records of a body, against other records held by the same or another body to see how far they match. The data is usually personal information. The data matching allows potentially fraudulent claims and payments to be identified. Where a match is found it may indicate that there is an inconsistency that requires further investigation. No assumption can be made as to whether there is fraud, error or other explanation until an investigation is carried out.

The processing of data by the Cabinet Office in a data matching exercise is carried out with statutory authority under its powers in Part 6 of the Local Audit and Accountability Act 2014. It does not require the consent of the individuals concerned under the Data Protection Act 1998.

All bodies participating in the Cabinet Office’s data matching exercises receive a report of matches that they should investigate, so as to detect instances of fraud, over- or under-payments and other errors, to take remedial action and update their records accordingly.

Legal basis

From 1 April 2015 the National Fraud Initiative will be conducted using the data matching powers bestowed on the Minister for the Cabinet Office by Part 6 of the Local Audit and Accountability Act 2014 (LAAA). Previous exercises were conducted by the Audit Commission under Part IIA of the Audit Commission Act 1998.

Under the LAAA powers:

    1. A relevant minister (meaning a Secretary of State or the Minister for the Cabinet Office) may carry out data matching exercises or arrange for them to be conducted for the purpose of assisting in the prevention and detection of fraud.
    2. A relevant minister may require certain persons to provide data for data matching exercises. Currently these are a relevant authority (as defined in section 2 of LAAA); a best value authority (as defined in section 1 of the Local Government Act 1999) which is not a relevant authority; and an NHS foundation trust.
    3. Other bodies and persons may participate in its data matching exercises on a voluntary basis where the relevant minister considers it appropriate. Where they do so, the statute states that there is no breach of confidentiality and generally removes any other restrictions in providing the data to the relevant minister.
    4. The requirements of the Data Protection Act 1998, however, continue to apply.
    5. A relevant minister may disclose data provided for data matching and the results of data matching exercises where this assists in the prevention and detection of fraud, including disclosure to bodies that have provided the data and to auditors that they appoint.
    6. A relevant minister may disclose both data provided for data matching and the results of data matching to the Auditor General for Wales, the Comptroller and Auditor General for Northern Ireland, the Auditor General for Scotland, the Accounts Commission for Scotland and Audit Scotland, for the purposes of assisting in preventing and detecting fraud or in connection with audit functions of those bodies.
    7. Wrongful disclosure of data obtained for the purposes of data matching by any person is an offence and liable on summary conviction to a fine not exceeding level 5 on the standard scale.
    8. A relevant minister may prescribe a scale or scales of fees in respect of data matching.
    9. A relevant minister must prepare and publish a Code of Practice. All bodies conducting or participating in its data matching exercises, including the relevant minister himself, must have regard to the Code.
    10. A relevant minister may report publicly on his data matching activities in a manner the relevant minister considers appropriate for bringing it to the attention of those members of the public who may be interested.
