When the premium goes up

The UK's largest money forum has a pet-insurance thread most months, and the titles say the same thing in different voices: "Pet insurance keeps increasing significantly and I'm not sure whether to just self insurance at this point"; "Pet Plan dog insurance nearly £200 a month for 11 year old"; "Is pet insurance worth it? Nothing I need now is covered?" This page is for the renewal letter. Why the number went up, which consumer rule does not protect you, what "lifetime" actually promises, the self-insure sum done honestly, and the one free route of appeal.

Why it goes up

Three things, and only one of them is about your dog. The first is age. Our calculator runs the premium for a standard-colour French Bulldog in the North West with a £100 excess from £42 a month at eight weeks to £66 at three, £100 at six and £150 at nine; the baseline curve behind it, from aggregated UK broker figures, reaches £230 a month at twelve. That is the shape of every lifetime policy for this breed, whether or not you ever claim. The second is the vet's bill. The Competition and Markets Authority's investigation into veterinary services found that "Between January 2016 and December 2023, average prices at veterinary businesses across the sector grew by 63%", and premiums follow claims. The third is the breed and your dog's own history: insurers price by breed, and a dog that has claimed is a dog that is expected to claim again.

The rule that does not apply

Since 2022 a home or motor insurer has not been allowed to charge a renewing customer more than it would charge a new one for the same policy. That rule is chapter 6B of the FCA's insurance conduct rules, and its title is its scope: "Home insurance and motor insurance pricing". Pet insurance is not in it. So the renewal price on your letter is not tested against a new-customer price, and if a quote for the same dog as a new customer comes out lower, nothing in the rulebook says it should not. Ask for the new-customer price. The answer is information, not a lever, because of the next section.

What "lifetime" means

The Financial Ombudsman's definition is the one that matters, because it is the one a complaint gets judged against: lifetime policies are those "providing cover for the lifetime of the pet, as long as the policy is renewed each year." Read the second half. The cover is for the dog's life; the price is for one year at a time, and the promise holds only while you keep paying whatever the next letter says. What you cannot do is take the promise elsewhere. The commonest reason the Ombudsman lists for a declined claim is that "your pet was already suffering from a condition before you took out the policy", and a dog that has claimed for BOAS or a disc has that condition for life on any new policy. The insurance guide says never switch, and this is why: the negotiating position at year six was decided at year one.

The self-insure sum, done honestly

Add up the baseline curve from eight weeks to twelve and it comes to £18,588 in premiums. Over a median 9.8-year life, that same North West dog pays £10,513, against an expected vet spend of £2,496, weighted by how likely each of the breed's conditions is. On average, insurance for this breed costs about four times what it is expected to pay out. That is not a scandal; it is what insurance is. The question it does not answer is the only one that matters: can the household pay one bill of £3,000 to £9,000, which is our estimate for a disc operation, or £1,800 to £4,500 for airway surgery, in the month it arrives.

The pot

A pot works if it starts at eight weeks, gets the premium paid into it every month, and the dog stays well for the first two or three years. It fails when the first bill lands in year two, which for the breed that gets disc disease youngest is not rare. And a pot has one property a policy does not: it is still yours if the dog is well. The honest middle course is the one the money-forum threads arrive at on their own. Keep lifetime cover through the years the pot is small. Put the difference between what you pay and what you would pay for a cheaper policy into the pot anyway. Review at the age when the pot exceeds the largest single bill, which on our numbers is somewhere past six for most households, and remember that a dog with a claimed condition is a dog that stays insured, because the decision to leave has already been made for you.

The Ombudsman route

The Financial Ombudsman Service is free, and its pet-insurance page lists the grounds it will take a complaint on. Among them: "the price of the policy has significantly increased"; "exclusions have been added onto the policy either at the outset, or mid-term – that is after you bought it and before renewal – and then backdated"; "the deductions for policy excesses, co-payments, or policy limits have been unfairly applied to the claims settlement"; and "the terms and conditions of a lifetime policy have changed."

The process

Complain to the insurer first, and "If they don't send you a final response within eight weeks – or you're unhappy with their response – you can complain to us." What the service weighs is fairness and what you were told: "whether the policy was described as 'lifelong' or 'lifetime'" and "how much information your insurer gave you when you took out the policy". It does not set prices. A rise that the insurer explains and that the policy allowed is a rise; a rise that came with a changed limit, a new co-payment or an exclusion you were not told about is a complaint. Keep every renewal letter.

At renewal, in this order

1. Ask the insurer in writing what changed: age band, claims, a general repricing, or a change to the policy terms.
2. Put the new schedule beside last year's. The per-condition limit, the excess, any co-payment percentage, and any new exclusion are the four lines that matter more than the premium.
3. Get a new-customer quote for the same dog from the same insurer. No rule prevents the gap, but you are entitled to know it.
4. If the dog has claimed for anything that could recur, stay. A new policy will exclude it.
5. If the dog has never claimed and is under about five, compare lifetime policies on the per-condition limit, and never let the old one lapse before the new one starts.
6. If the terms changed and you were not told, or the rise came with a new exclusion, complain, wait eight weeks, then use the Ombudsman.
7. Whatever you decide, the difference goes in the pot.

What we did not read

The Association of British Insurers' claims statistics, the insurers' own pages on why premiums rise, MoneyHelper's guidance and the Ombudsman's uphold rates for pet insurance all refused automated reads on 12 September 2026, so none is quoted. The premium curve and the expected-spend figures are our model's, sourced and labelled in the calculator. Post titles from the money forum are public; nothing here identifies anyone.
