The short answer
- Buy lifetime cover while your dog is young and healthy, because anything that shows up before the policy starts is usually excluded for good.
- Check whether the vet-fee limit is per year overall, per condition per year, or both, since a single expensive condition can hit a per-condition cap fast.
- Find the age at which a co-payment starts (commonly 8 or 10, earlier for some breeds) and budget for paying roughly a fifth of every claim from then on.
- Renew without a break: a lapse of even a day can turn your dog's ongoing conditions into pre-existing ones with a new insurer.
- Treat the renewal letter as a decision point and complain to the insurer, then the Financial Ombudsman, if a rise looks unexplained.
Lifetime pet insurance in the UK is a policy whose vet-fee limit resets every time you renew, so an ongoing condition such as arthritis, allergies or diabetes can keep being claimed for the rest of your dog’s life. The catch is that you have to keep renewing without a gap, the premium will almost certainly climb as your dog ages, and most policies start asking you to pay a share of each claim somewhere between ages 8 and 10.
It is the type Which? describes as the most comprehensive, and every one of its Best Buy pet policies is a lifetime policy. That does not make every lifetime policy good, or the same.
How lifetime cover differs from the other UK policy types
UK insurers sell four broad types of dog insurance, and the difference comes down to what happens to a condition after the first year.
| Policy type | What happens to an ongoing condition | Who it suits |
|---|---|---|
| Accident-only | Illness is never covered | Budget cover for injuries only |
| Time-limited | Covered up to a cap, usually for 12 months from the start of the claim, then excluded | One-off problems such as a broken leg |
| Maximum benefit | Covered until a fixed amount for that condition is used up, then excluded for good | Short-lived illnesses |
| Lifetime | Limit refreshes at each renewal, so the condition stays covered while you keep the policy | Dogs likely to develop long-term conditions |
Which? warns that a maximum benefit policy stops covering a condition once its limit is reached, even if you renew, and that time-limited cover typically excludes a condition 12 months after the claim begins. The Financial Ombudsman Service (FOS) adds that those 12 months usually start when a vet first recommends investigation or treatment, not when you send the claim form.

The three ways lifetime limits are built
“Lifetime” describes how the limit renews, not how big it is. Which? sets out three structures:
- One annual limit for everything, for example £5,000 a year across all conditions.
- A limit per condition, per year, for example £2,000 a year for a single condition.
- Both together, for example £10,000 a year overall with no more than £2,000 for any one condition.
The third type catches people out. A dog with five unrelated problems could claim £2,000 for each, but a single expensive one, such as a cruciate ligament repair followed by physiotherapy, stops at £2,000 that year. Which? says overall cover on UK policies typically runs from £1,000 to £25,000.
Two real examples, as published when we checked in November 2026:
- Petplan Covered For Life offers £4,000, £7,000 or £12,000 of vet fees, refreshed every year as long as you renew with no break in cover.
- Animal Friends Lifetime policies range from £1,000 to £18,000 per policy year depending on the level chosen, and some levels also cap each condition at £1,000 to £6,000 per year.
Big numbers matter more than they used to. The Association of British Insurers (ABI) says its members paid out a record £1.23bn on pet claims in 2024, with dogs accounting for £933m of it, according to Which?. Which? also reports that the Competition and Markets Authority found UK vet prices rose 60% between 2015 and 2023, against 35% for general service inflation, and that treating elbow dysplasia can exceed £50,000. A £4,000 annual limit buys less each year.
Why the premium rises, and by how much
Lifetime premiums go up for two separate reasons, and both apply even if you never claim.
Your dog gets older. Which? says insurers generally treat dogs over eight as older pets and charge more to cover them, because they are more likely to fall ill or be injured.
Vet fees keep rising. Petplan states plainly on its Covered For Life page that premiums will rise over the life of the policy, because of rising vet costs and advances in treatment. It also says it will never charge more because you have claimed. Not every insurer makes that promise, so look for it.
Nobody publishes a standard yearly increase, and we won’t invent one. What we can say is that the wider market has been moving the other way lately. Insurance Business UK, reporting the Defaqto pricing index in November 2026, says average premiums for the top five lifetime policies fell 14% in the 12 months to September 2026. The same report warns that insurers seem to be protecting margins through product design instead, with co-payments, higher excesses and inner limits, and that Defaqto expects selective price rises to return.
In practice, a falling headline price can hide a policy that now pays less of each bill.
The co-payment that arrives at 8 or 10
A co-payment (some insurers call it an age-related excess) is a percentage of every claim you pay on top of your fixed excess. On UK lifetime policies it usually switches on at a set birthday.

| Insurer and policy | When it starts | How much |
|---|---|---|
| Animal Friends Lifetime (where a co-payment applies) | Age 8 | 20% of each vet fee claim |
| Petplan Covered For Life | Usually the 10th birthday, 7th for some breeds | 20% of each claim, plus the fixed excess, with at least a year’s notice |
| Market-wide, per Which? | Older pets, generally dogs over 8 | Can be as high as 25% |
This is becoming more common, not less. The Defaqto figures reported by Insurance Business UK show 41% of policies carried a co-payment in 2026, up from under a third at the start of 2025.
Here is what that does to a claim, using invented round numbers. Your 10-year-old dog runs up a £3,000 bill. Your fixed excess is £150, leaving £2,850. A 20% co-payment on that is £570, so you pay £720 in total and the insurer pays £2,280. Check your own wording for whether the percentage is taken before or after the fixed excess, because insurers differ.
One rule works in your favour. The FOS says excesses and co-payments should be deducted before the policy limit is applied. It does not think it fair to apply the limit to the claim before those deductions are made.
Is a co-payment at 10 fair?
The FOS looked at exactly this in a final decision dated May 2024 (DRN-4732288). A dog had been insured with Petplan since 2012, and at the 2023 renewal a 20% co-payment was added because the dog had turned 10. The owner said she hadn’t known it would happen.
The ombudsman found that the documents at the original sale could have been clearer, but that renewal paperwork since 2019 had flagged the change, and she had been given 12 months’ notice. Adding the co-payment didn’t change the cover itself, so it wasn’t a fundamental change to a lifetime policy. The ombudsman also noted that a co-payment for older pets is “very common”, saying most, if not all, policies have one. The complaint was not upheld. Petplan had already paid £100 for the distress caused.
Expect a co-payment, then, and find the trigger age in your documents now, not in the renewal letter that introduces it.
Renewal: the rules that protect you, and the ones that don’t
Most UK pet policies renew automatically, and Which? says you should get a renewal notice showing what you paid last year, with many insurers giving at least 21 days to cancel. A new policy also comes with a 14-day cooling-off period.
What you don’t get is the renewal price protection that applies to some other insurance. The Financial Conduct Authority’s ban on charging renewing customers more than new ones, which took effect on 1 January 2022, was introduced for home and motor insurance. Its announcement does not extend it to other products, so don’t assume a pet renewal quote is matched to a new customer’s price.
There is still a backstop. The FOS says it won’t tell insurers what price to charge, but it does check whether a premium was set fairly. That includes the reasons for an increase and whether future rises were disclosed. A complaint is likely to be upheld if a rise is aimed at profiting unfairly from a customer or group, or is designed to push them into not renewing. It also says that where a policy is sold as lifetime cover, insurers normally can’t reduce its core cover at renewal.
The process is to complain to your insurer first, then take it to the FOS if you are unhappy with the answer.
The switching trap
With car insurance, shopping around every year is good advice. With lifetime pet insurance, it can quietly cost you the cover you have been paying for.

A new insurer will usually treat anything your dog has had signs of, advice for or treatment for as pre-existing and exclude it. Which? says some insurers cover pre-existing conditions after a symptom-free period, such as two years, or after a medical screening, but that isn’t the norm. Law firm Browne Jacobson made the same point in 2024: owners of older pets can’t easily shop around when premiums rise, because other insurers won’t cover what the current one already does.
There are age limits as well. Petplan, for example, only starts new Covered For Life policies up to age 8 for most breeds, or 5 for certain breeds.
If your dog is young and has a clean history, switching is low risk. If your dog has had ear infections, skin flare-ups or a limp, compare the new policy’s exclusions line by line first. Our guide to pre-existing conditions explains how insurers decide what counts.
What lifetime cover still won’t pay for
Lifetime does not mean everything. Policies still exclude:
- Pre-existing conditions, and illness that starts in the first 10 to 14 days of a new policy, which Which? says most insurers won’t cover.
- Routine care such as vaccinations, neutering and flea and worm treatment.
- Anything above your annual or per-condition limit in a given year.
The FOS expects insurers to point out pre-existing condition exclusions at the point of sale and in the policy summary, known as the Insurance Product Information Document (IPID). Pointing to the full wording isn’t enough. It also says a claim refusal is unlikely to be fair if the owner couldn’t reasonably have known about the problem, especially if a vet had said there wasn’t one.
Five questions to ask before you buy or renew
- Is the vet-fee limit per year, per condition per year, or both, and how much?
- At what age does a co-payment or extra excess start, and does it start earlier for my breed?
- Will claiming raise my premium?
- What happens to my dog’s conditions if I miss a payment or the renewal lapses?
- Is the fixed excess likely to change at renewal? Petplan, for one, says it can.
If you are weighing whether cover is worth the cost at all, our dog cost calculator can help put the premium next to everything else you spend.
The bottom line
Lifetime pet insurance is the only common UK policy type that keeps paying for the same long-term condition year after year, which is why it suits most dogs. The trade-off is a premium that rises with age and vet inflation, plus a co-payment of about 20% that usually starts between 8 and 10. Choose a limit structure that can cope with one expensive condition, buy before problems appear, and never let the policy lapse. When the renewal letter arrives, read it line by line, and use the Financial Ombudsman if a change looks unfair.
Questions owners ask
What is the difference between lifetime and time-limited pet insurance?
Lifetime cover resets its vet-fee limit every year you renew, so a condition like arthritis can keep being claimed for as long as the policy runs. Time-limited cover usually stops paying for a condition 12 months after the claim began, and maximum benefit cover stops once a fixed amount per condition is used up.
At what age do UK pet insurers add a co-payment?
It varies by insurer and breed. Which? says dogs over about eight are generally treated as older pets. Animal Friends applies a 20% co-payment from age 8 on policies that carry one, and Petplan's Covered For Life usually adds a 20% excess at the 10th birthday, or the 7th for some breeds.
Will my lifetime premium go up if I claim?
Premiums on lifetime policies tend to rise over time because of vet fee inflation and your dog's age, whether or not you claim. Some insurers, Petplan among them, state they will not charge more because you claimed, so check your insurer's wording.
Can I switch lifetime insurer when my dog is older?
You can, but a new insurer will usually exclude anything your dog has already had signs of or treatment for, and some stop accepting new dogs at a set age; Petplan, for example, starts new Covered For Life policies only up to age 8, or 5 for some breeds. For a dog with ongoing conditions, switching often means losing cover for exactly the things most likely to cost money.
Can an insurer cancel or downgrade my lifetime policy?
The Financial Ombudsman Service says that where a policy is sold as lifetime cover, insurers normally can't cut back its core cover at renewal, and it may step in if they do. Changes such as adding a co-payment with enough notice have generally not been treated as a fundamental change.
