Pet Insurance to Avoid? The Big-Name Policies to Think Twice About
Which big-name UK pet insurance policies to think twice about, and what to switch to instead. Time-limited cover from household brands, low lifetime limits, and co-payments that start at 4 or 5, all from the insurers' own documents.
Published 28 October 2026
Most big-name pet insurance in the UK is fine, if you buy the right policy. The ones to think twice about are Direct Line, Churchill and the Direct Line cover Aviva points you to, which only pay for each condition for 12 months; More Than's lifetime cover, which tops out at £6,000 a year; and Asda's lifetime cover, which adds a co-payment from age 5 and caps scans and cruciate treatment at £1,500. Among specialists, Lifetime Pet Cover starts a co-payment at 4 and Purely Pets at 6.
This is not about whether these companies are honest. It is about what their policies actually pay for. Every fact here comes from the insurers' own websites and policy documents, checked in October 2026, and each one comes with a better switch.
At a glance
| Brand | What to watch | Better switch |
|---|---|---|
| Direct Line | Time-limited only: £4,000 per condition, for 12 months | Any lifetime policy in our top 10 |
| Churchill | Time-limited only: £3,000 per condition, for 12 months, plus 20% of every claim from age 7 | Post Office or Animal Friends lifetime cover |
| Aviva | Points you to Direct Line's time-limited Essential cover, for pets up to 10 | As Direct Line |
| More Than | Lifetime cover only up to £6,000 a year, compulsory co-payment after age 9 | Animal Friends, up to £18,000 a year |
| Asda | 10% co-payment from age 5, £1,500 caps on scans and cruciate treatment | Post Office, up to £12,500 a year |
| Lifetime Pet Cover | Co-payment from age 4, rising to 30% at 12 | Waggel, no forced co-payment |
| Purely Pets | 20% co-payment from age 6, around 50 breeds excluded | Waggel or Petplan |
The cheap-tier trap
The biggest risk with a household name is not the brand. It is the cheapest policy on its quote page.
Tesco, Sainsbury's, the Post Office and John Lewis all sell good lifetime cover, underwritten by Pinnacle Insurance. But each also sells time-limited cover, which pays for each condition for 12 months and then stops, or maximum benefit cover, which pays up to a set amount per condition and then stops for good. Both are cheaper, and both can sit right next to lifetime cover on the quote page.
Our guide to whether lifetime pet insurance is worth it shows what that difference costs over a dog's life. For most dogs, the conditions that cost the most are the ones that last. If you buy from a big brand, check the policy name on your quote says Lifetime.
Direct Line, Churchill and Aviva: 12-month cover only
These three brands all lead to the same kind of policy, from the same group. Direct Line and Churchill are underwritten by U K Insurance Limited, part of the Direct Line group, which Aviva now owns.
- Direct Line sells one pet policy, Essential. It pays up to £4,000 for each condition, for 12 months from the first treatment, then stops. Our Direct Line review has the detail.
- Churchill sells only time-limited cover, at £3,000 for each condition, for up to 12 months. For pets aged 7 or over, you also pay an extra 20% of every vet fees claim. That is a co-payment on a policy that already stops paying after a year.
- Aviva does not sell its own pet policy. Its pet insurance page points you to Direct Line's Essential cover, for cats and dogs from 8 weeks up to 10 years old.
Time-limited cover can help with an accident or a one-off illness. It will not keep paying for arthritis, allergies, diabetes or a heart condition. Better switch: lifetime cover. If you want a big, familiar name, the Post Office sells lifetime cover up to £12,500 a year. For a higher limit at a budget price, Animal Friends goes to £18,000.
More Than: low lifetime limits
More Than is now a trading name of EUI Limited, part of the Admiral group. It sells three kinds of cover:
| Policy | Type | Vet fees |
|---|---|---|
| Basic | Time-limited, 12 months per condition | £1,500 or £3,000 |
| Classic | Maximum benefit, per condition | £4,000 or £8,000 |
| Premier | Lifetime, reset each year | £1,000, £2,000, £4,000 or £6,000 |
Its lifetime cover tops out at £6,000 a year. That is less than half the Post Office's £12,500 and a third of Animal Friends' £18,000, and a serious condition such as cancer or cruciate surgery can use most of it in a single year. A compulsory co-insurance amount starts at the renewal after your pet's 9th birthday. Better switch: Animal Friends, up to £18,000 a year, or the Post Office.
Asda: a co-payment from age 5, and low caps
Asda's pet insurance is arranged and administered by Insurance Factory Limited. Its lifetime policies run from £2,000 to £10,000 a year, and its website leads with a low headline price. The policy wording and product summary show where that price comes from:
- A 10% co-payment from your pet's 5th birthday, on every lifetime level, on top of the fixed excess. Most of the insurers we rank start at 7 or later, and some never force one.
- £1,500 caps on CT and MRI scans, on cruciate ligament treatment (per leg), and on complementary treatment (per condition), whichever lifetime level you choose.
- The excess is charged again if your pet is referred to another vet.
- Dental illness is only covered on the £6,000, £8,000 and £10,000 levels.
- Specialist diets are capped at £250, and behaviour treatment is only covered after an accident.
- Death from illness cover ends at 7.
- If you cancel after a successful claim, the rest of the year's premium is still due.
Better switch: the Post Office sells lifetime cover up to £12,500 a year, and we found no low caps on scans or cruciate treatment in its wording. Our guide to pet insurance co-payments shows what a co-payment from age 5 adds up to.
Specialists with early co-payments
Two smaller insurers we have reviewed in full also start charging a share of every claim much earlier than most.
- Lifetime Pet Cover charges 15% of each claim from age 4, 25% from 7 and 30% from 12, on top of a £199 excess per condition every year. It also takes no new dogs aged 12 or over, and excludes agility.
- Purely Pets charges 20% of every claim from your dog's 6th birthday, and it never comes off. It excludes around 50 breeds, including Staffies and Rottweilers, and caps cruciate cover per leg for life.
Better switch: Waggel never forces a co-payment at any age, and Petplan waits until 10 for most dogs.
The big names that checked out
To be fair to the household names, several are good on the facts:
- Post Office, underwritten by Pinnacle: lifetime cover up to £12,500 a year, 12 months to claim, and a place in our top 10.
- Tesco, underwritten by Pinnacle: lifetime cover up to £11,000 a year, a Which? Best Buy on its lifetime policies above £5,000.
- Sainsbury's, underwritten by Pinnacle: lifetime cover up to £10,000 a year, and Defaqto's Pet Insurer of the Year two years running.
- John Lewis, underwritten by Pinnacle: lifetime cover is the only type you can buy direct. Time-limited and maximum benefit cover are sold only through comparison sites.
- Admiral: lifetime cover up to £10,000 a year, and its website states no co-payment.
The same rule applies to all of them: buy the lifetime policy, not the cheapest one on the page.
How we judged this
We used the same method as our ranking of the best pet insurance: what the policy pays when you claim, when you start paying more of each bill, and what the small print excludes. We did not use Financial Ombudsman complaint figures to judge individual insurers. The Ombudsman publishes them per firm across every kind of insurance a firm sells, not for pet insurance alone, so they cannot fairly be pinned on a firm's pet policies.
If you are already with one of these
Do not cancel in a hurry. If your dog has been treated for anything, a new insurer will almost certainly exclude it, and you could lose cover for the very thing you most need. If your dog has a clean history, switching to lifetime cover is usually safe, and several insurers, including the Post Office, Petgevity and Everypaw, drop their waiting periods if you switch with no gap in cover. Line the new policy up to start the day the old one ends.

Common questions
Which pet insurance should I avoid?
For most dogs, avoid any policy that only covers each condition for 12 months, because it stops paying for long-term problems like arthritis or allergies. Direct Line, Churchill and the Direct Line policy Aviva points you to only sell that kind of cover. Also think twice about lifetime policies with low limits or early co-payments, such as More Than's lifetime cover, which tops out at £6,000 a year, and Asda's, which adds a co-payment from age 5.
Is supermarket pet insurance any good?
Some of it is very good. Tesco, Sainsbury's and the Post Office all sell lifetime cover underwritten by Pinnacle Insurance, with limits of £10,000 to £12,500 a year and strong claims records. The catch is that each one also sells cheaper time-limited or maximum benefit policies, so check the quote is for lifetime cover. Asda's lifetime cover is weaker, with a co-payment from age 5 and low limits on scans and cruciate treatment.
What is the worst type of pet insurance?
For most dogs, time-limited cover. It pays for each condition for 12 months from the first treatment, or up to a set amount, and then stops. Accident-only cover is narrower still. Both are cheaper, but they leave you paying for the conditions that cost the most over a dog's life.
Is Direct Line pet insurance good?
It is a short-term policy, not lifetime cover. Direct Line Essential pays up to £4,000 for each condition for 12 months, then stops. It can help with an accident or a short illness, but not with a condition your dog has for life. That is why it is not in our top 10.
Should I switch pet insurance if my dog already has a condition?
Be careful. A new insurer will almost always exclude anything your dog has already had, so switching can leave the condition you most need covered with no cover at all. If your dog has a clean history, switching to better cover is usually safe. Petgevity's Lifetime Plus and ManyPets' pre-existing plan are the main exceptions that may cover some existing conditions.
