Low and high are the model midpoint × 0.70 and × 1.45. This intentionally broad planning range is a model assumption, not a measured confidence interval or a promise of available quotes.
These are published market observations, not outputs invented by this calculator. MoneySuperMarket describes its figures as the 51st and 10th percentiles of one-pet quotes created from April to June 2026; check its current methodology notes before comparing them with a live quote.
| Pet and cover | Monthly “from” | Average monthly |
|---|---|---|
| Dog — accident-only | £3.95 | £3.96 |
| Dog — time-limited | £6.30 | £13.24 |
| Dog — maximum-benefit | £7.35 | £15.46 |
| Dog — lifetime | £6.28 | £13.76 |
| Cat — accident-only | £3.02 | £3.02 |
| Cat — time-limited | £4.18 | £7.40 |
| Cat — maximum-benefit | £4.64 | £8.24 |
| Cat — lifetime | £3.87 | £8.17 |
In the same MoneySuperMarket data, average dog premiums rose from £8.76 at age 1–2 to £22.74 over age 7; cats rose from £5.72 to £12.44. This model uses those age relationships, but a renewal increase is not predicted.
The ABI reported an average pet-insurance claim of £685 in 2024, while treatment after a pet swallowed a harmful substance or object could cost around £4,000. ABI data covers participating member firms, not the whole market.
Accident-only excludes illness. Time-limited cover restricts how long a condition can be claimed. Maximum-benefit sets a total per-condition pot. Lifetime cover can renew a vet-fee allowance each policy year while the policy remains active.
A modest consultation may sit below an excess; a £1,500 investigation may trigger excess and co-pay; a recurring condition can exhaust a time-limited or per-condition pot. Always compare the policy wording, not price alone.

Inputs: England, lifetime cover, £5,000 limit, £150 excess, 80% reimbursement.
Premium: about £7–£15 a month; midpoint about £10.
£1,500 bill: £100 uncovered → £1,400 eligible → subtract £150 excess → insurer pays 80% (£1,000) → owner pays £500.
Inputs: Scotland, lifetime cover, £8,000 limit, £150 excess, 80% reimbursement.
Premium: about £10–£21 a month; midpoint about £15.
Age is the largest uplift. A live quote may add an age-related co-pay even if the selected model scenario does not.
Inputs: England, lifetime cover, £12,000 limit, £100 excess, 90% reimbursement.
Premium: about £28–£58 a month; midpoint about £40.
A £4,000 fully eligible bill with no prior limit use gives: £3,900 after excess × 90% = £3,510 insurer payment; owner pays £490.
Worked premium figures are rounded outputs from model UK-PI 2.0. Claim examples assume the excess applies before reimbursement and ignore any other policy sub-limits.
Policies commonly cover eligible veterinary treatment for new accidents or illnesses. Routine care, elective procedures, pregnancy, grooming and preventable treatment may be excluded. Dental, complementary treatment, diagnostics and prescription food can have special definitions or sub-limits.
New policies usually exclude conditions or symptoms that existed before cover. Check whether hereditary and congenital conditions are unrestricted. A bilateral-condition clause can treat a problem on one side of the body as related to a later problem on the other side.
Cover normally starts after a waiting period, which can differ for accidents and illnesses. Entry-age caps, higher excesses and compulsory percentage co-pays may apply to older pets. Renewal is not the same as guaranteed unchanged price or terms.
An excess might apply once a year, once per condition, or to every claim. A co-pay is your percentage after the excess. Confirm whether the vet-fee limit is annual, per condition, or a total pot, and whether smaller sub-limits apply.
Premiums commonly rise as a pet ages and veterinary costs change. If a condition is diagnosed, a new provider may exclude it as pre-existing. Do not cancel existing cover until you understand what replacement cover accepts and excludes.
Savings avoid exclusions and premiums but may not absorb a large early or recurring bill. Insurance can transfer part of that risk but never covers everything. Compare the annual premium, realistic owner share, maximum payout and savings you could access immediately.

Market, sample and period: United Kingdom, GBP only. Cover/species/breed/age anchors use MoneySuperMarket one-pet quotes created from April to June 2026; its “average” figures are described as the 51st percentile and “from” figures as the 10th percentile. Regional coefficients use Go.Compare quotes collected 1 January–18 May 2025. The model was last reviewed 18 July 2026.
pre-tax midpoint = (species + cover average ÷ 1.12) × breed × age × region × excess × reimbursement × limit × add-ons
premium midpoint = pre-tax midpoint × 1.12
low = midpoint × 0.70; high = midpoint × 1.45; annual = monthly × 12
MoneySuperMarket average monthly anchors including IPT: dog £3.96 accident, £13.24 time-limited, £15.46 maximum-benefit, £13.76 lifetime; cat £3.02, £7.40, £8.24 and £8.17 respectively. HMRC's standard Insurance Premium Tax rate is 12%. Currency cannot be changed: replacing “£” with “$” or “€” would not convert or localise the underlying data.

eligible = max(0, bill − uncovered charges)
excess due = excess already met ? 0 : min(excess, eligible)
after excess = eligible − excess due
available limit = max(0, selected limit − limit already used)
insurer reimbursement = min(after excess × reimbursement rate, available limit)
owner payment = bill − insurer reimbursement
remaining limit = available limit − insurer reimbursement
annual cost in this scenario = annual premium midpoint + owner payment
Limitations: The model does not use medical history, exact postcode, insurer appetite, promotions, multi-pet discounts, pet sex, neutering, weight or prior claims. Those inputs were deliberately removed because this model lacks reliable coefficients for their precise pricing effect. Cover averages come from comparison visitors rather than a representative census of all UK policies. Results can therefore differ materially from live quotes.
UK-PI 2.0 — 18 July 2026: replaced currency relabelling and the £22 universal baseline with UK sources; added cover types, real breed choices, age/area calibration, planning ranges, claim mode, progressive disclosure, examples and accessible results. This is the first version with a published claim formula.
MoneySuperMarket's April–June 2026 quote data showed a published average of £12.84 a month across dog policies in its one-pet sample. Cover type, age, breed, area, excess and policy limits can move an individual quote far above or below that figure.
MoneySuperMarket's April–June 2026 quote data showed a published average of £7.39 a month across cat policies in its one-pet sample. Older cats, some breeds and more comprehensive cover can cost more.
Often yes, but fewer insurers may accept a new older pet, premiums and co-payments can be higher, and age limits vary. Check entry-age and renewal terms before buying.
Common factors include species, breed, age, postcode or region, cover type, vet-fee limit, excess, co-payment and the insurer's own pricing and eligibility rules.
Usually not on a new policy. A new insurer may also treat a condition diagnosed under an old policy as pre-existing, so switching after a diagnosis can remove cover for that condition.
The excess is the eligible amount you pay before the insurer contributes. Reimbursement is the insurer's share after that excess; a 20% co-pay means 80% reimbursement.
Lifetime cover can fund ongoing conditions while the policy remains in force and is renewed. Its vet-fee limit normally refreshes each policy year, but premiums, excesses and terms can change at renewal.
It depends on your savings, risk tolerance and the cover offered. An emergency fund is flexible but may be exhausted by a large or recurring bill; insurance transfers some risk but has premiums, limits and exclusions. Some owners use both.
