Your right to a copyWhere the footage identifies you, UK GDPR obliges the operator to release a copy. One calendar month from receipt is allowed for the answer; where the request is complex, or one of several from the same person, the operator may take up to two months more, and must say so within the first month. Anyone else appearing is blurred beforehand, and a fee is charged only in unusual circumstances.
Put the hold in writingAn email on the day is worth more than a solicitor's letter a fortnight on. Say which camera and which half hour, then ask — in writing — that the footage be held.
When the police askAn officer asks, the operator says yes, and that informal route is how most footage reaches a Thames Valley Police enquiry. Refusal turns it formal — a data-protection request first, then an application to the court.
Where we fit inA disk formatted by accident. A recorder that stopped on the night in question. An export somebody removed from an office PC. Those normally come back, at £400 + VAT, and on most jobs there is no fee if nothing does. Footage the loop has covered comes back for nobody.
