02What happened, and where it sits

London Borough of Hammersmith and Fulham received an ICO reprimand on 16 May 2025. The Commissioner acted under the UK General Data Protection Regulation, citing UK GDPR Article 5(1)(f) and UK GDPR Article 58(2)(b). A formal criticism on the public record. A reprimand carries no fine and no order, but it is published and the ICO expects the shortcomings named in it to be fixed.

No sum is attached to this action. Reprimands are corrective, not financial, which is why London Borough of Hammersmith and Fulham appears on the register without a figure beside it.

GDPRFine.com is an independent tracker of ICO enforcement. It is not affiliated with, endorsed by or connected to the Information Commissioner's Office, and it uses no ICO branding. Where the ICO's own wording is reproduced it is quoted and attributed; everything else on these pages is our own summary of the published record.

The ICO's register held 222 entries on that date. 6 of them are prosecutions of named individuals, with ages and home towns in the ICO's own summary. This tracker indexes organisations, so those 6 are excluded and every count on these pages is out of 216. They remain on the ICO's own register.

An entry says what the Commissioner did on the date shown. It is not a statement about the organisation today, and the ICO can amend or remove a register entry at any time. Amounts and provisions are as published by the ICO; where the published notice does not state a figure or name a provision, these pages say so rather than filling the gap.
