How to claim on UK pet insurance: step-by-step guide

The claims process is where pet insurance either works or it doesn’t. This guide explains how UK pet insurance claims actually work in 2026, what the insurer needs from you and your vet, and what to do if a claim is refused.

The two ways a claim is paid

Direct vet pay

The insurer settles the bill with the vet. You pay only the excess and any co-payment at the practice. This is the lowest-stress, fastest route.

Three things to know:

1. The vet practice has to agree. Most do for bills above £500 or so. A few don’t engage with direct vet pay at all.
2. The insurer has to authorise it. Modern insurers (ManyPets, Napo, Waggel) often pre-authorise treatment based on the vet’s estimate. Petplan and Agria handle it case-by-case but generally accept.
3. It works best for planned procedures. Surgery scheduled a few days in advance is straightforward. Emergency same-day treatment sometimes can’t be set up in time, in which case it reverts to reimbursement.

If direct vet pay matters to you, ask your vet practice in advance which insurers they routinely settle with. Some are easier than others.

Reimbursement

You pay the vet upfront, then claim back from the insurer. The insurer pays you (minus excess and co-payment) typically within 5 to 14 working days for routine claims.

Most claims still go through this route, especially smaller ones. The downside is cash flow — you might be £4,000 down for a couple of weeks.

What you need to claim

Five things, most of which the vet provides:

1. Itemised invoice

Not just a total. The insurer wants the line items: consultation fee, medication, lab work, surgery, hospitalisation. UK vet practices generate itemised invoices as standard.

2. Claim form

Online or app for modern insurers. PDF or paper form for older ones. The form asks about:

• Pet details (name, breed, date of birth)
• Policy number
• The condition being claimed for
• When symptoms first appeared
• The vet practice handling treatment

3. Vet clinical notes

For the specific visit being claimed, the vet’s clinical notes confirming what was done and why. Most practices supply these as a printout on request.

4. Full clinical history (for larger or complex claims)

For claims above a few thousand pounds or for any chronic condition, the insurer usually wants the pet’s full history from the vet. This is where claims slow down — practices vary widely in how quickly they generate full histories. Following up the practice can shave a week off the claim.

5. Original or photo of receipts

Modern insurers accept photos. Older ones sometimes still want originals (rare in 2026 but not unknown).

Step-by-step: a typical reimbursement claim

A worked example: your dog has a £600 ear infection treatment.

Day 1 (treatment day).

• Pay the vet at the practice
• Take a photo of the itemised invoice on your phone
• Ask the vet to send the clinical notes for the visit

Day 1 evening.

• Open the insurer’s app or portal
• Start a new claim, fill in the basics
• Upload the invoice photo and clinical notes
• Submit

Days 2 to 5.

• Insurer acknowledges receipt
• For straightforward claims, no further information needed
• For more complex claims, insurer might request full clinical history from the vet (this is where delays start)

Days 5 to 14.

• Claim assessed
• Decision and payment

Day 7 to 21.

• Payment lands in your bank account

For most routine claims under £1,000 with no pre-existing question, the whole process is closer to 5 to 7 days. For chronic conditions or anything where the insurer needs to validate the full history, it can stretch to 4 to 6 weeks.

How to speed up a claim

Five practical tips:

1. Photograph the invoice immediately

Don’t wait to get home. Photograph the itemised invoice in the practice waiting room. The clearer the photo, the faster the assessment.

2. Use the app

If your insurer has one (ManyPets, Napo, Waggel, Bought By Many, Petplan, Animal Friends), use it. Email submissions are slower than app submissions at every insurer that offers both.

3. Submit clinical notes upfront

Don’t wait to be asked. If the vet can give you the clinical notes for the visit on the day, upload them with the invoice. Saves a follow-up cycle.

4. Chase the vet for full history if needed

If the insurer requests full clinical history, ring the vet practice rather than email. Most can generate the history in a few days when prompted. Some take weeks if left to their own schedule.

5. Use direct vet pay where possible

Removes the cash flow problem entirely and usually settles faster than reimbursement. Ask both the vet and the insurer in advance.

What to do if a claim is refused

UK pet insurers must give a written reason for any claim refusal. Common reasons:

“Pre-existing condition”

If you believe the condition isn’t pre-existing, gather:

• Vet records showing the first time the condition was diagnosed (after policy start)
• Any earlier vet visits where the condition was specifically ruled out
• A letter from your vet stating their clinical opinion on whether the current condition relates to anything in the historic record

Submit these as a formal complaint to the insurer.

”Condition arose during waiting period”

Same approach. The key date is the first time symptoms were noted. If the vet’s notes are clear that symptoms started after the waiting period ended, you have a case.

”Treatment not covered by policy”

Read the policy schedule carefully. If the wording is genuinely ambiguous, the FOS often interprets it in favour of the policyholder. If the wording is clear and the treatment is excluded, the refusal will stand.

”Missing documentation”

The easiest fix. Get the missing item, resubmit.

How to escalate a refused claim

Three steps:

1. Formal complaint to the insurer

Every UK insurer has a formal complaints process. Use it. Set out:

• The claim reference
• The refusal reason
• Why you disagree
• Supporting evidence

The insurer must respond within 8 weeks under FCA rules.

2. Escalate to the Financial Ombudsman Service

If the insurer’s response is unsatisfactory, you can escalate to the Financial Ombudsman Service (FOS) free of charge. Submit within 6 months of the insurer’s final response letter.

The FOS is genuinely independent and decides cases on what’s fair and reasonable. They uphold a meaningful proportion of pet insurance complaints, especially around ambiguous wording and pre-existing definitions.

3. Consider seeking advice from Citizens Advice

For complex cases or if you’re unsure how to present your complaint, Citizens Advice can help.

Summary

UK pet insurance claims work through apps or portals at most modern insurers. Direct vet pay is the fastest, lowest-stress route for larger bills. Reimbursement is the standard for smaller claims and typically takes 5 to 14 working days.

If a claim is refused, you have a formal right to complain and escalate to the Financial Ombudsman Service. Don’t accept a refusal that you genuinely believe is wrong.
