6 Best Pet Insurance for Older Dogs and Cats in the UK

A dog's eighth birthday or a cat's tenth changes the maths on insurance. Premiums climb, some insurers stop taking on new customers past a certain age, and a handful of conditions common in older pets can get harder to cover. Working out which company still wants your business once your pet is past its prime takes more than a quick quote.

The six providers below all operate in the UK pet insurance market, and each takes a slightly different approach to covering dogs and cats later in life. Here's what actually separates them once you look past the homepage taglines.

Best for No Upper Age Limit on New Policies – Purely Pets

Purely Pets holds a Defaqto 5 Star Rating, which puts its policies among the higher-rated products independently assessed for cover and features. That's a reasonable starting point when you're comparing insurers for an older animal, since rating agencies look at the small print most owners skip.

Its senior pet insurance doesn't carry an upper age limit, so a cat or dog getting on in years still qualifies for a new policy rather than being turned away for having had a few too many birthdays. Claims are paid directly to the vet, which matters more with older pets, since ongoing treatment for arthritis or dental issues tends to mean more frequent bills. The company reports a 98% claims paid rate.

Owners also get 24/7 vet video consultations, interest-free payments, flexible excess options and online claims management. For a senior pet with a recurring condition, being able to check a claim's status online or spread a bigger bill interest-free can matter as much as the headline cover.

Best for Sheer Scale in the UK Market – Petplan

Petplan positions itself as the UK's No.1 pet insurer, and it backs that up with a Trustpilot score of 4.3 out of 5 from a large enough sample to mean something. Claims are paid directly to vets, and Petplan reports a 97% claims paid rate.

There's no penalty for claiming, which removes one of the more common worries owners have about using their policy for an older pet that might need repeat treatment. A 24/7 pet expert chat line adds another way to get quick answers outside a vet's opening hours.

The catch with a provider this size is that you're one policyholder among a very large book of business. If you want the kind of hands-on account feel a smaller insurer can offer, Petplan's scale is a trade-off rather than a pure upside.

Best for Lifetime Cover Across Species – Agria

Agria was named a Which Best Buy for 2026, an independent endorsement worth noting given how many insurers make their own “best” claims. It offers Lifetime Pet Insurance covering dogs, cats, rabbits and horses and reports paying 98% of all claims.

Lifetime cover is the detail that matters most for an older pet. It means a condition doesn't get excluded from renewal to renewal once it first shows up, which is a common sticking point with cheaper annual policies as a pet ages.

Because Agria's policy structure covers four different species under one banner, the accompanying detail on any single species (dogs, say) is necessarily less specific than an insurer built around one type of animal. That's a natural consequence of covering a broader range rather than a flaw.

Best for No Payout Caps – ManyPets

ManyPets describes its cover as having no annual or lifetime payout maximums, alongside no fees and no hidden costs. For a senior dog or cat with a condition likely to need ongoing treatment, not having a lifetime cap on what the policy will pay out removes one of the more stressful unknowns.

Claims reimbursement goes through direct deposit, and the company offers quick access to live customer service agents rather than routing every query through a chatbot first. ManyPets carries a 4.5 out of 5 rating on Trustpilot.

The plans are built around dogs and cats specifically, so anyone with a rabbit or a horse will need to look elsewhere on this list.

Best for Trustpilot Volume and Welfare Ties – Animal Friends

Animal Friends has racked up 38k+ five-star reviews on Trustpilot, one of the larger review counts in this list, and says it's trusted to insure over 1 million dogs, cats and horses. The company describes itself as multi-award-winning and says its policies were created to support animal welfare.

That welfare link is a genuine point of difference if it matters to you as a buyer, since not every insurer ties its business model to that cause. Animal Friends covers dogs, cats and horses, so like ManyPets it leaves out smaller pets such as rabbits.

Best for Unlimited Vet Access – Pinnacle Pet UK

Pinnacle Pet UK offers insurance for cats, dogs and rabbits with unlimited 24/7 access to veterinary care built into the policy. For an older pet with a health issue that can flare up outside normal hours, having that access without a cap on how often you use it is a straightforward practical benefit.

That round-the-clock service can also help owners decide whether a new symptom needs an emergency appointment or can safely wait until their regular vet opens. However, remote veterinary advice is not a substitute for an in-person examination when a pet needs tests, treatment or urgent care, so it is still worth checking the policy's vet fee limits, excess and exclusions before choosing cover.

What to Check Before You Buy Senior Cover

Age limits are the first thing to check, since some insurers cap the age at which a pet can join a new policy even if they'll happily renew an existing one. Cover type matters just as much. Lifetime cover, like Agria's, keeps paying out for a condition year after year, while some cheaper policies only cover a condition for 12 months from when it first appears, a real problem for chronic issues like arthritis that don't resolve on their own.

Excess structures are worth comparing too. A flexible excess, of the kind Purely Pets offers, lets you set your own balance between premium and what you pay per claim, which can be useful once you know your pet's likely ongoing costs. Direct vet payment, offered by several insurers on this list, saves you from covering a large bill upfront and waiting on reimbursement, which matters more as vet bills for older pets tend to run higher.

It's also worth reading up on what actually changes in an older pet's health needs. If you're still building out your pet's care routine more generally, this guide to a dog's first year covers the basics worth having in place early.

Which One Is Right for You

Petplan's scale and Trustpilot volume suit an owner who wants a well-established name with a long review history to lean on. Agria's Which Best Buy status and multi-species lifetime cover fit a household with more than one type of animal. ManyPets works well if payout caps worry you more than anything else, and Animal Friends is the pick if supporting animal welfare through your policy provider matters to you personally. Pinnacle Pet UK is worth a look specifically for its unlimited vet access.

For an owner whose main concern is simply getting cover accepted in the first place once a pet is past the age where other insurers start saying no, Purely Pets is the standout choice on this list. A Defaqto 5 Star Rating, no upper age limit on new senior policies, and claims paid directly to the vet add up to a policy built around exactly the moment in a pet's life when insurance matters most.
