Benefits-record anonymisation is the removal of claimant PII from a welfare or benefits file. Once it is truly anonymous, UK GDPR Recital 26 takes it out of scope. anonym.plus does this on your own device, so the data stays useful for reporting.
When this applies
An oversight body or a researcher asks for benefits data. The file names claimants and holds their IDs, addresses, and award amounts.
How anonym.plus handles it
- Open the benefits file in anonym.plus on your device.
- The tool flags claimant names, IDs, and contacts.
- Swap each one for a non-reversible label.
- Keep no re-link key if you want it outside scope.
- Confirm the award figures still read clearly.
- Save the anonymous file on your machine.
What you need to provide
- The benefits file (CSV, XLSX, PDF, or DOCX).
- Replace, with the reversible map turned off.
- Optional language setting for the records.

Limitations & cautions
True anonymity is a high bar. If you keep a reversible map, the file is pseudonymous, not anonymous, and stays in scope. A rare award plus a small area can still re-identify. Weigh the residual risk before you treat the data as anonymous.
Frequently asked questions
Anonymous or pseudonymous — what is the difference?
Pseudonymous output keeps a key that can re-link it, so it stays personal data. Anonymous output drops that key for good. Only then does Recital 26 take it out of scope.
Can I keep the award amounts?
Yes. The figures stay for reporting. Only personal IDs are removed, so trends and totals are still analysable.
Does it read a benefits spreadsheet?
Yes. CSV and XLSX files are scanned column by column, and free-text fields get the same review as documents.
