How long we keep your information

For the purposes of engagement, contact emails and names where available, will be kept on our stakeholder database, which is a live document that will change and evolve over time as and when stakeholder details change. We will keep this information for as long as is necessary or until you inform us it is no longer valid, or until you opt out, at which point we will then dispose of your information in the most secure manner possible.

We will retain engagement information until our work on the subject matter of the consultation or engagement is complete.

We generally retain Survey Data which is personal data for no longer than 6 months after we have completed any quality control checks.  In some instances, data may be retained for longer periods where the processing purpose requires this.

We may anonymise your personal data (so that it can no longer be associated with you) for research or statistical purposes in which case we may use this information indefinitely without further notice to you.

Data Matching and Auditing

We are required by law to protect the public funds we administer. We may use the information you provide to us for the prevention and detection of crime. We may also share this information with other bodies that are responsible for auditing or administering public funds including the Department for Work and Pensions, other local authorities, HM Revenue and Customers and the Police.

The council uses data matching as a way of processing large volumes of information. While this can be a useful way of detecting fraud, it also enables us to identify information that is inaccurate or out of date, helping us comply with Data Protection law, while improving service provision.

As part of the council’s fraud prevention and detection activities, the council participates in the National Fraud Initiative (NFI). The data matching exercise is run by the Cabinet Office. More information  is available online.
