Understanding What You’re Really Paying For
How do you know which pet insurance policy will actually help when you need it?
What’s the real difference between “lifetime,” “per condition,” and “accident only” cover, and how do those limits work in practice?
Pet insurance can be confusing. Policies often look similar on the surface, but the details around claim limits, exclusions, and timeframes can make a huge difference when your pet becomes unwell. It’s easy to assume everything will be covered, only to discover later that a clause or time limit applies.
This guide explains what to look for, how different policy types work, and the key things to check before you buy or switch - so you can choose the right level of protection for your pet and avoid costly surprises later on.
Every company promises peace of mind, but what they actually cover can vary widely once you read the small print.
While most private human medical insurance has no upper limit on costs, all pet insurance policies include a financial cap - usually applied per policy year. The insurer agrees to cover claims up to a fixed amount during that period, and any costs above that limit must be paid by the owner.
Alongside the policy limit, there are also more subtle differences between plans, usually falling into four main areas:
How long a condition is covered for
What kinds of problems are included
How claim limits work
How the excess is applied
Understanding these points helps you choose a policy that genuinely protects your pet, rather than one that looks affordable, but lets you down when you need it most.
Lifetime Cover vs 12-Month ("time-limited") Cover
Lifetime insurance is the most complete form of cover. It provides a total yearly allowance - often between £3,000 and £20,000 per year depending on the insurer and level chosen, that resets each policy year. If your cat develops thyroid disease or your dog needs ongoing treatment for arthritis, the condition remains covered year after year as long as the policy renews without a break.
This type of policy is ideal for chronic or recurring issues. Long-term conditions such as diabetes or skin disease can easily cost £600 - £1,000 per year in medication and monitoring, so continuous cover is important. Monthly premiums are higher, but the peace of mind is worth it for most owners.
Time-limited policies work differently. They pay for the treatment of each condition for up to 12 months from the first claim, then stop paying for that problem altogether. Even if your pet still needs care, the cover ends permanently after that window. These plans can be tempting because they’re cheaper, but when a short-term issue becomes a chronic one, you’ll find yourself funding everything privately once the 12 months are up.
In short, lifetime cover renews and continues for as long as your pet needs it, while 12-month policies only help in the short term.
Accident-Only vs Comprehensive Cover
Accident-only insurance covers injuries such as fractures, road traffic accidents or swallowed objects, but not illnesses. It doesn’t include things like infections, ear problems, dental disease or cancer - the issues most owners actually claim for. Premiums are often cheap, but limits are often also low.
Comprehensive policies include both accidents and illnesses. They also cover diagnostics like x-rays, blood tests, ultrasound and lab fees, which can easily cost £500 - £800 depending on the case. Surgery, hospitalisation, medication, and sometimes dental work or acupuncture are also included. Monthly premiums are higher, but this type of cover reflects how veterinary care is actually delivered in modern practice and provides genuine protection for your pet’s health.
Maximum Benefit Per Condition, vs Maximum Overall
Some insurers offer a “maximum benefit per condition” policy, where each condition is given a set amount of money - typically £2,000 - £5,000 - and once that’s spent, cover for that condition stops permanently.
With a 'per condition' cap, if your Labrador develops hip arthritis and reaches the per-condition limit, any further X-rays, medications, or check-ups for that hip will no longer be covered by insurance. For example, even if your overall policy limit is £15,000, a £3,000 per-condition cap means you can only claim up to £3,000 for that specific issue. The remaining balance on the policy can’t be used for ongoing treatment of the same condition.
The alternative is where the policy gives you one total pot of money to use across all treatments in a given year. When the policy renews, that allowance resets in full. While these policies cost more upfront, they offer consistent, renewable cover that doesn’t run out when you need it most.
One Annual Excess vs Excess Per Condition
It may seem trivial, but it's an important distinction, given that excess is the contribution you pay towards each claim. Most policies apply a fixed excess per condition - usually £120 - £250. A few insurers will offer policies with a single excess per year - this is simpler and easier to budget for, especially if your pet has multiple health issues in a single year.
Other insurers apply the excess to each condition - a pet treated for both skin disease and cystitis might therefore incur two excesses.
In practical terms, if you're on a policy with a single annual excess (i.e. not per condition), that's the maximum you'll ever pay per year for claimable fees. Using the above example, if you claimed £300 for skin diease, with a £120 annual excess, your insurer would re-imburse you £180 for that condition. If you then went on to claim £150 for cystitis (in the same policy year), you would be re-imbursed for the whole amount (£150). Furthermore, if you then claimed, say, £90 for an eye condition, they would also re-imburse you for the full amount (£90).
Once your pet reaches a certain age, many insurers also add a percentage-based co-payment (effectively an additional excess) - typically 10 - 20% of each claim - on top of the fixed excess. A £2,000 claim with a 15% co-payment and a £99 excess would leave the policy-holder paying around £399.
While per-condition excesses make premiums look cheaper, they can quickly add up when your pet has more than one ongoing issue or as they age. A single annual excess offers more predictability and fewer surprises.
Should I consider anything else?
It’s also important to understand a few other aspects of how pet insurance works, especially when it comes to switching insurers or managing longer-term conditions.
Switching insurers and pre-existing conditions
Whilst you can often get a better deal by switching your car or home insurance, medical insurance (both for pets and humans) works differently. When you change insurers, the new company will usually exclude anything your pet has been treated for before - even possibly for a single episode. This is called a pre-existing condition. Car insurers will take your driving history into account, but normally only go back 3-5 years - and even then they'll still offer insurance, it just costs more. Medical insurers will go back right to the start of your pet's life.
For example, if your dog was treated for an ear infection last year, a new insurer might exclude the ears from future cover. Vets have to submit the entire medical history when a claim is made, so the insurer will know about pre-existing conditions, even if you haven’t mentioned them before. For pets with ongoing or recurring issues, it’s best to stay with the same insurer, even if premiums rise, as switching almost always resets exclusions.
Some insurers might consider cover for a pre-existing condition if there have been no symptoms, treatment, or noted clinical signs for a certain period - usually in the preceding 6 months to 2 years, depending on the policy. It’s worth checking the small print carefully, as each insurer applies its own time frame and definition of what counts as “symptom-free.”
Claim time limits
Most insurers require claims to be submitted within a specific time frame - often between 3 and 12 months from the date of treatment. Claims received after this window are automatically declined, even if the treatment would otherwise have been covered. Always check your policy wording and keep copies of invoices so nothing gets missed.
Continuation claims and multiple clinics
Many health problems need repeated visits or care from different clinics. For example, your pet might see their GP vet for initial treatment and then be referred to a specialist for scans or surgery. In these cases, all treatment related to the same diagnosis is classed as a continuation claim.
Only one excess is payable per condition per policy year - you don’t pay a new excess each time you visit the vet or referral centre for the same problem. However, all clinics involved must record the same diagnosis so the insurer recognises it as one ongoing claim. If the condition is described differently on separate invoices (for instance, “lameness” at one clinic and “cruciate injury” at another), the insurer may treat them as separate conditions and charge an additional excess.
How is the premium likely to change over time?
It's worth asking insurers how your premium is likely to change - either as you claim or as your pet gets older. This is an important consideration, especially given that once you've chosen an insurer, switching can be risky as we've explained. We frequently see clients cancelling unaffordable policies in older pets.
Insurers assume that the likelihood of you making a claim in the future is higher if you've already claimed - and some will increase the price of your policy as a result. Some clients have told us that relatively small claims have significantly increased their premiums, sometimes more than the actual amount claimed for.
It's also worth considering how your premiums will increase as your pet ages. Again, insurers know that the highest likelihood of making a claim is from around 7 years of age upwards. With some insurers, the premiums can increase steeply.
What actually matters?
In our opinion, these are the 4 most important things to get right in a policy:
Lifetime Cover
Comprehensive Cover, not accident-only
Adequate Cover extending to several thousands of pounds. More extensive policies might also include dental disease and complementary therapies such as acupuncture or physiotherapy.
Non-Excluded Cover - bear in mind pre-existing conditions, especially if you're taking out insurance on an adult pet, or if you're considering shopping around at the point of renewal.
Policies that only cover accidents, exclude illness after 12 months, or set an overall limit below £3,000 tend not to offer real financial protection. And remember, it’s best to start your pet’s cover early, before any symptoms or diagnoses appear in their medical record.
Making the Decision
Pet insurance is really about preparation. The question isn’t whether you can afford a monthly premium, but whether you could comfortably manage a sudden £4,000 (or more) bill if your pet needed urgent surgery tomorrow.
A lifetime, comprehensive policy with a clear annual limit and one manageable excess gives you the freedom to make the right choices for your pet without hesitation.
At Battersea Square Vets, we see every week how good insurance makes treatment easier, faster, and far less stressful for owners. It allows us to focus on care, not costs.
We're not financial advisors so can't tell you which policy to take, but if you’re comparing policies or unsure what’s realistic for your pet’s breed and age, we’re always happy to explain the small print.
Choosing the right cover now can save you enormous worry later - and it’s one of the most important things you can do for your pet’s lifelong wellbeing!
