Vet fees for a serious illness or injury can run into thousands of pounds, and the NHS safety net has no equivalent for animals. This guide explains the main types of pet insurance policy, what they typically exclude, and how premiums behave as your pet ages.
Accident-only — the cheapest tier, covering injury from accidents but not illness
Time-limited (maximum benefit) — covers a condition up to a set amount or for 12 months, whichever comes first, then excludes it permanently
Lifetime (annual limit) — the vet fee limit renews each year you continue the policy, so ongoing conditions stay covered indefinitely
Lifetime (per-condition limit) — a variant of lifetime cover with a separate, renewing limit for each different condition rather than one shared annual pot
Common Exclusions
Nearly all policies exclude pre-existing conditions (anything showing symptoms before the policy started or during any waiting period), routine and preventative care such as vaccinations, flea/worming treatment, neutering, and dental cleaning, and breeding-related costs. Many policies also exclude or cap cover for hereditary and congenital conditions common to certain breeds, so if you own a breed prone to a specific condition, check the wording for that condition by name before relying on the policy.
How Premiums Change With Age
Pet insurance is priced year to year based on your pet's current age and claims risk, not fixed for life, so premiums typically rise as your pet gets older — sometimes steeply once a cat or dog reaches its senior years. Some insurers also increase the co-payment percentage on claims once a pet passes a certain age, which effectively reduces the payout even if the premium and cover limit look unchanged.
Excess and Co-Payments
Most policies charge a fixed excess per condition per year, often in the £100–£250 range, plus an age-related co-payment percentage on top — for example 20% of the vet bill once your pet reaches a certain age, in addition to the fixed excess. Always compare the combined effect of the excess and co-payment, not just the headline premium, when shopping around.
Choosing a Policy
Decide how much ongoing protection you want against chronic conditions before comparing price
Check the vet fee limit per year (or per condition) and whether it is enough for specialist treatment in your area
Read the exclusions list for your specific breed, especially hereditary conditions
Consider staying with the same lifetime insurer long term, since switching can turn an ongoing condition into an excluded pre-existing one
Factor in Insurance Premium Tax and any optional add-ons (routine care, third-party liability, travel cover) when comparing total cost
Self-Insuring Instead
Some owners choose to set aside their own savings instead of paying rising premiums, particularly for older pets where age-loading makes insurance expensive. This only works as protection if the fund is actually built up before an emergency and is large enough to absorb a serious illness or surgery; many owners find a hybrid approach — insuring while young, then reviewing at renewal each year — helps balance cost against risk.
What is the difference between lifetime and time-limited pet insurance?
Lifetime cover renews your vet fee limit each year for as long as you keep renewing the policy with the same insurer, so an ongoing condition like diabetes can keep being claimed for year after year. Time-limited (or "maximum benefit") cover pays out up to a set amount for a condition, but once that limit is reached or 12 months pass, that condition is permanently excluded from future claims, even if you keep paying premiums.
Is lifetime pet insurance always the best option?
For most owners, lifetime cover gives the strongest ongoing protection because chronic conditions in older pets are excluded far less often. It is usually more expensive than accident-only or time-limited policies, so cost-conscious owners sometimes choose a lower level of cover while their pet is young and healthy, accepting the risk that a serious chronic diagnosis later would not be covered for life.
Why do pet insurance premiums go up as my pet gets older?
Insurers price pet insurance on a rolling annual basis reflecting your pet's current age and claims risk, not a fixed rate for life. As pets age they are statistically more likely to need vet treatment, so premiums typically rise each renewal, sometimes sharply once a pet reaches its senior years, even with no claims made.

Are pre-existing conditions ever covered?
Almost never on a new policy taken out after a condition first shows symptoms — this is standard across the market, not specific to one insurer. Some providers offer limited "pre-existing condition cover" if the condition has been symptom-free and untreated for a defined period, but this is the exception rather than the rule, so check the policy wording carefully before assuming a past issue will be covered.
Does pet insurance cover routine and preventative treatment?
Standard vet fee policies generally do not cover routine costs like vaccinations, flea and worming treatment, neutering or annual health checks — these are considered predictable running costs, not insurable events. Some insurers offer an optional add-on or a separate wellness plan for routine care, usually at extra cost.
Is Insurance Premium Tax charged on pet insurance?
Yes. Pet insurance is subject to standard-rate Insurance Premium Tax like most general insurance in the UK, which is built into the premium you are quoted rather than added separately at checkout.
What excess will I have to pay per claim?
Most policies combine a fixed excess (for example £100–£250) with a co-payment percentage that can also increase with your pet's age — for example 20% of the claim on top of the fixed excess once your pet passes a certain age. Always check both the fixed excess and any age-related co-payment percentage, not just the headline excess figure.
Should I insure an older pet or self-insure by saving instead?
It depends on your risk tolerance and savings discipline. Insuring an older pet is expensive because of age-loading, but a single serious illness or injury can cost thousands in vet fees. Self-insuring (setting aside a dedicated savings pot) only works if you actually build the fund before an emergency arises and are comfortable carrying the full financial risk yourself.
What happens if I switch insurer partway through my pet's life?
Switching to a new insurer generally means any ongoing or historic condition becomes a "pre-existing condition" for the new provider and is excluded from cover, even if your previous lifetime policy was still covering it. This is one of the main reasons owners stick with the same lifetime insurer for years despite rising premiums.
Does pet insurance cover third-party liability if my dog injures someone?
Some pet insurance policies include third-party liability cover as standard or as an add-on, which can help with legal costs and compensation if your dog injures a person or damages property. This is separate from vet fee cover, so check whether your policy includes it, particularly for breeds where liability risk may be higher.
