How to Document an Insurance Claim: The Evidence That Gets You Paid

Two near-identical claims; one paid in full, one refused. The difference is almost always the evidence. Exactly what to gather, the photos that win claims, and the mistakes that sink them.

By Alice T · ClaimPilot editorial team

Two people make almost identical insurance claims. One gets paid in full within a fortnight. The other gets a request for "further information," then a partial offer, then a flat refusal. The difference usually isn't the policy, the insurer, or luck. It's the evidence. A claim is, at its heart, a story you're asking the insurer to believe — and evidence is what turns your word into a fact they can't argue with.

This guide is the practical version: exactly what evidence to gather, what wins claims, and the mistakes that quietly sink them. Get this right and you remove the insurer's easiest reason to say no.

Why evidence decides claims

When you claim, the insurer's assessor is asking three questions: did this actually happen the way you say, did you really own and value the items at what you state, and does the policy cover it? Strong evidence answers all three before they can be used against you. Weak evidence leaves gaps — and gaps are where claims get reduced or refused. The burden is on you to prove your loss, not on the insurer to disprove it.

The evidence every claim needs

Whatever you're claiming for, these form the backbone:

Proof the event happened — a crime reference number for theft or vandalism, a police report for an accident, a plumber's or electrician's report for damage, dated photos taken at the time.
Proof of ownership and value — receipts, bank or card statements, order confirmation emails, photos of you with the items, original packaging, serial numbers, valuations for jewellery or watches.
A clear, dated account — a written timeline of what happened and when, including when you first noticed the loss and when you reported it.
Your policy documents — the wording and schedule, so you can point to the exact cover that applies.

Photos: the evidence that wins claims

For damage and contents claims, photographs are the single most persuasive thing you can provide — if you take them properly.

Photograph immediately, before you clean up or make repairs. Insurers are wary of claims where the scene has already been "tidied." If you must make emergency repairs to prevent further damage, photograph thoroughly first.
Capture wide and close. Wide shots show context (the whole room, the whole vehicle); close-ups show the detail of the damage.
Show the cause if you can — the burst pipe, the broken window, the fallen branch. Linking damage to a sudden, covered event is what separates a payout from a "wear and tear" refusal.
Get serial numbers and labels in shot for electronics and appliances.
Date everything. Most phones embed the date automatically; keep the originals rather than screenshots so the metadata survives.

A good rule: photograph as if you'll have to prove every detail to someone who wasn't there. Because you will.

Build a "claim file" before you ever need it

The best time to assemble evidence is before disaster strikes. A simple home inventory — a folder of photos and receipts for your valuable possessions — turns a stressful, memory-based claim into a quick, documented one. Walk through your home filming each room, open drawers and cupboards, capture serial numbers, and store it somewhere safe (cloud storage, or emailed to yourself). For a few minutes' work, you remove the single hardest part of any contents claim: proving what you actually owned.

Claim-specific evidence

Motor claims: photos of all vehicles and damage at the scene, the other driver's details and registration, witness contact details, a sketch or note of how it happened, and the police reference if reported. Dashcam footage, if you have it, can settle a disputed claim instantly.

Home claims (escape of water, storm, fire): photos of the damage and the source, a tradesperson's report on the cause, receipts for damaged contents, and evidence of maintenance (to defeat a "lack of maintenance" argument).

Theft and burglary: the crime reference number is essential — report to the police first. Photograph any point of entry, and provide proof of ownership for everything stolen.

Travel claims: medical reports and receipts, a police report for stolen items abroad, proof of travel and dates, and original receipts for anything you're claiming back.

The evidence mistakes that get claims refused

Reporting late. Even great evidence loses force if you waited weeks to report. Notify the insurer first, gather details after.
Throwing things away. Don't dispose of damaged items until the insurer confirms they don't need to inspect them. The damaged item is itself evidence.
Repairing before documenting. Fix what you must to prevent further loss — but photograph first.
Vague valuations. "It was worth about £800" invites a low offer. A receipt or valuation gets you the real figure.
Inconsistent accounts. Your written timeline, your phone call, and your form should all tell the same story. Contradictions are a red flag to assessors.
Exaggerating, even slightly. Rounding "two years old" up to "nearly new," or adding an item you can't prove you owned, can void the entire claim under the policy's fraud condition. Claim exactly what you lost.

When the insurer asks for "more information"

A request for further evidence is normal — it's not a refusal, and it's not personal. Respond promptly, in writing, and provide exactly what's asked plus anything that strengthens your case. Keep copies of everything you send and a note of every call. The claimant with the organised, complete file almost always gets a better, faster outcome than the one sending fragments weeks apart.

The bigger picture: evidence is won before the claim

Here's the pattern worth internalising. The strongest claims are the ones where the evidence already existed — the receipts kept, the inventory filmed, the photos taken at the moment of damage. By the time you're claiming, you either have the proof or you don't. The households that get paid in full are usually the ones that documented as they went, not the ones scrambling to reconstruct a loss after the fact.

That's exactly the gap ClaimPilot is built to close. Before you submit, it checks your claim the way an assessor would — telling you which evidence is missing, which photos you still need, and where the gaps are that would let an insurer say no. Fix those gaps while you still can, and you turn a claim you're hoping gets paid into one that's hard to refuse.
