Pet insurance for older dogs with pre-existing conditions

Q: What is a co-payment on older dog insurance?

A co-payment is a percentage of each claim, often around 20 percent, that you pay in addition to the fixed excess once your dog reaches a certain age. It is the insurer sharing the higher cost of treating older pets. A small number of premium policies waive it.

Insuring an older dog that already has a health problem is the hardest case in the pet market: age pushes the premium up and adds co-payments, while the existing condition is usually excluded outright. A few specialist insurers still help, on terms. Here is what cover is realistically available in the UK in 2026, and how to weigh it against self-funding.

Quick answer

Can you insure an older dog with pre-existing conditions?

Yes, but with important limits. Almost every standard UK policy permanently excludes any condition your dog already has or has shown symptoms of, and most mainstream insurers also refuse new customers once a dog is around 8 to 10 years old, or apply a compulsory co-payment on top of the excess. A small number of specialist insurers — ManyPets and Petgevity (formerly Petsure) are the best known in 2026 — have no upper age limit and can cover conditions that have been stable and treatment-free for a set period, typically at least three months. Cover for the existing illness will always cost more, not less, so many owners of an older dog with a known condition weigh a specialist policy against setting money aside to self-fund.

Standard policies exclude the existing condition and anything clinically linked to it, usually for life.
Age adds cost on top: higher premiums, a co-payment (often around 20%) once a dog is older, and many insurers close to new joiners past 8 to 10.
Specialist insurers can help if the condition has been stable for the required symptom-free period; expect a higher price and careful medical screening.
If you already hold a lifetime policy, keep it — switching insurer turns today’s covered conditions into tomorrow’s exclusions.

Four realistic routes for an older dog with a condition

There is rarely a perfect answer. Each route trades price against how much of the existing problem is actually protected.

Route	What it does	The existing condition
Keep your existing lifetime policy	Renew the cover your dog already holds, without switching insurer	Stays covered
Specialist pre-existing insurer	New policy that can include stable conditions after a symptom-free period	May be covered
Standard new policy	Fresh cover for new, unrelated illnesses and accidents only	Excluded
Self-fund with a savings pot	Set aside a regular amount to meet vet bills yourself	You pay

Indicative routes for orientation only — not a quote or a recommendation. The right choice depends on the condition, your dog’s age and your budget.

Why it is difficult

How insurers treat older dogs and existing conditions

Two separate rules stack up against an older dog with a health history, and it helps to see them apart.

Age. Vet bills rise steeply in a dog’s senior years, so insurers price accordingly. Many mainstream providers stop accepting brand-new customers once a dog is around 8 to 10 years old, though they will keep renewing a policy started earlier. Once a dog passes a set age, most insurers also apply a co-payment: a percentage of every claim — commonly around 20 percent, sometimes rising with age — that you pay on top of the fixed excess. A handful of specialist insurers set no upper age limit at all, and one or two premium tiers waive the age co-payment entirely.

The pre-existing condition. A pre-existing condition is any illness or injury your dog has shown signs of before cover starts. Standard policies exclude it, and usually anything clinically related, for the life of the policy. Insurers often split conditions into curable and incurable: a one-off, fully-resolved problem may be reconsidered after your dog has been symptom-free and treatment-free for a period — two years is a common threshold — whereas an ongoing condition such as arthritis or diabetes typically stays excluded. Specialist pre-existing insurers work differently, covering conditions that have been stable for a shorter window, often at least three months, after an online medical screening.

Where cover still exists

Insurers that may cover older dogs with a condition

A short list of UK insurers is built specifically for pets that mainstream policies turn away. They cost more than standard cover, and each assesses your dog individually, so treat the notes below as a starting point for your own research rather than a recommendation.

ManyPets offers a pre-existing option designed to include conditions that have been stable — no treatment, medication or advice — for at least three months, with no upper joining age on its senior cover.
Petgevity (formerly Petsure) specialises in older pets and pre-existing conditions, sets no upper age limit, and uses an online medical screening to price each pet; its top tier can waive the age-related co-payment.
Mainstream lifetime insurers such as Petplan, Agria and others remain the best home for a condition you are already claiming for — but only if you never let that policy lapse or switch insurer.

Insurer names, terms and symptom-free windows change; always read the current policy wording and key facts document before buying, and check exactly how a condition is defined.

Making the decision

Practical steps for an older dog with a condition

Never cancel a policy that already covers the condition. The moment you switch insurer, that illness becomes pre-existing and is excluded by the new one. Continuity is worth more than a small saving.
Budget for the co-payment, not just the premium. On a large claim, a 20 percent co-payment plus the excess can be a meaningful sum, so factor it into whether the cover pays off.
Match the vet-fee limit to real risk. Older dogs are the pets most likely to need it, so a higher lifetime limit is usually worth the extra premium.
Compare a specialist quote against self-funding. If premiums plus co-payments plus excess approach what you would spend on treatment anyway, a dedicated savings pot can be the more rational choice for some conditions.
Get the full clinical history to hand. Specialist insurers screen medically, so an accurate vet record speeds the decision and avoids a claim being refused later.

Common questions

Older dogs and pre-existing conditions FAQs

Can I get pet insurance for a dog that already has a health condition?

You can still insure the dog for new, unrelated illnesses and accidents with almost any insurer, but the existing condition will normally be excluded. A few specialist insurers, such as ManyPets and Petgevity, can cover conditions that have been stable and treatment-free for a set period, usually at least three months.

Is there an age limit for insuring a dog?

Many mainstream insurers stop taking brand-new customers once a dog is around 8 to 10 years old, but they will keep renewing a policy that began earlier. Some specialist insurers set no upper age limit, so a senior dog can still be covered if you start with the right provider.

What is a co-payment on older dog insurance?

A co-payment is a percentage of each claim — often around 20 percent — that you pay in addition to the fixed excess once your dog reaches a certain age. It is the insurer sharing the higher cost of treating older pets. A small number of premium policies waive it.

When does a condition stop being pre-existing?

It depends on the insurer and whether the condition is curable. Some mainstream insurers will reconsider a one-off, fully-resolved problem after your dog has been symptom-free and treatment-free for two years. Ongoing conditions such as arthritis or diabetes usually remain excluded on standard cover.

Should I switch insurer to get a cheaper premium for my older dog?

Be very careful. If your current policy already covers a condition, switching insurer will turn that condition into a pre-existing exclusion on the new policy. For a dog with a health history, keeping continuous cover with the same insurer is usually more valuable than a lower headline price.

How much does insurance for an older dog cost in 2026?

There is no single figure. Lifetime cover for a healthy dog rises from roughly £150 to £240 a year at age one to well over £640 a year by age 11, and a pre-existing condition or specialist policy adds further cost. These are indicative ranges for orientation, not quotes.

Is it worth insuring an older dog, or should I self-fund?

Both can be sensible. If premiums, co-payments and excess together approach the likely treatment cost, a dedicated savings pot may be the more rational route for a specific condition. If your dog faces the risk of a large, unpredictable bill, insurance still spreads that risk. This is general information, not advice for your situation.
