Evidence & investigations · video a claim can stand on

CCTV evidence for a claim, Cardiff. A clip alone proves little; what surrounds it does the work.

Before a claims handler or an investigating officer will rely on a recording, they need to be satisfied it is what you say it is, and that case gets made at the recorder rather than afterwards. A written hold goes in while the machine can still reach the half-hour you need. Your rights under data-protection law are used properly. What we release then carries hash values and a dated record of everyone who held it. Lifting the video off the disk is the lesser part of the job.

How the footage comes out.

Subject access firstIf you can be picked out on the footage, UK GDPR puts the operator under a duty to hand you a copy. They get a calendar month, everyone else in shot is masked first, and charging is the exception.
A hold in writingAn email out that same afternoon — the date, the half-hour, the camera — carries further than a solicitor's letter arriving once the recorder has looped.
The police routeUsually an officer simply asks the operator for the recording and is given it — that is how most footage ends up in an investigation. If they refuse, the pressure has to come formally: a data-protection request first, an order from the court after that.
When the call reaches usGone round the loop before anybody exported a thing; a disk formatted in the meantime; a recorder that died that night — that is where we come in.

Two clocks, both running down.

01

A case number, and a diagnosis at no cost Free

The diagnosis costs you nothing. Every item that arrives is logged under a case number of its own, and an engineer works out what has actually failed — then tells you plainly which files can come back and which cannot. The price follows that: one fixed figure, in writing, and no work begins until you have read it and said go ahead.

Diagnosis at no chargeOne fixed figure in writingNothing owed yet
02

Stop the overwriting first

The first thing out is a written hold to whoever owns the system. Then we work out what the recorder actually retains — a figure that falls out of camera count and frame rate, not out of the handbook.

Hold notice out on day oneTrue retention calculated
03

Always two files

Two files come out of the image: an MP4 anything will play, and the recorder's own format — a .dav, say, or another maker's wrapper — packaged with the software that reads it.

MP4 and the native filePlayer supplied

The paperwork that travels with it

A SHA-256 value goes with each file, along with a written account of how it was made, and a dated log of every hand it passed through. Those three separate a clip forwarded by email from material a court or a loss adjuster can use.

SHA-256 values plus a noteReady for a claim or court
05

You approve it, then it goes back

Nothing is billed while you are still deciding. A complete listing of what came off the drive reaches you first, and the invoice only follows your yes. Files travel back on media bought new for the job, return postage ours, and we do not close it here until every one of them opens on the machine you will use.

Notes from the workbench

  • The cheapest thing you will ever send is one email — give the camera, the date and thirty minutes either side, put in writing that it must be kept, and no operator can later say the recorder had got there first.
  • A blurred face is not a blocked request — a shop hiding its other customers before it answers is meeting a duty it has to them under the same law you are using, not editing out the helpful part.
  • A camera at a front door is inside the rules — in 2021 a county court ruled on a video doorbell dispute and found that where the field of view reaches a neighbour's property or the pavement, its owner carries data-protection duties like anyone else.
  • The code for councils is not the code for a corner shop — the surveillance camera code binds forces and local authorities; a privately owned system is regulated instead by the ICO under data-protection law, and that is the standard our exports are built to.

What the insurer is looking at: ABI figures published in November 2025 put detected claims fraud at £1.16 billion for 2024, with 51,700 motor cases accounting for £576 million. Good video pays a genuine claim quicker and kills a staged one, but only if it arrives documented rather than forwarded.

Straight out of the casebook.

The deleted export that settled a two-van claim

The insurer wanted proof that two vans had collided in a yard. By then the recorder had gone round the loop several times and that day was long gone. One export survived — made by a manager at the time, then deleted from an office PC. We carved it back off that machine, hashed it, set the method down in writing, and the claim settled without a hearing.

Claim upheldCourt-ready export

Before you send it off.

Start with these

  • Send the preservation request today
  • Record the date, time, camera and who owns it
  • On the recording yourself? Use a SAR
  • Pass files on exactly as they came — no renaming, no cuts

What to avoid

  • Leave it to the insurer to chase
  • Hold a phone up to the screen and call it proof
  • Edit the clip down before passing it on
  • Take the manual's '30 days' on trust

The things people ask on the phone.

A shop's camera recorded me. Can I get a copy?

Yes. Once you are identifiable in the frame, that footage is your personal data and a subject access request reaches it. The operator has one calendar month, must obscure anyone else who can be recognised, and rarely charges.

What if the camera's owner refuses?

Start by asking politely — plenty of operators just hand over a copy. If the answer is no, two formal routes remain: a data-protection request, and beyond that an application to the court.

How long before the recorder overwrites it?

Sooner than the owner expects. No statute sets a retention period; data-protection law asks only that nothing is kept longer than needed, and 31 days became the habit. A busy system with several cameras laps itself well inside that.

What does a finished export need to include?

It must open on an ordinary machine and withstand a challenge, so an export leaves here as four things: an MP4, the original recorder format, SHA-256 values, and a signed note describing how each was made.

That recorder is still writing over it.

While that recorder keeps writing, the clip you need is being covered over — and your deadline has not moved. Book it in. The first look is free, and it stays private.
