How to choose pet insurance: the 8 questions to ask

This guide gives you the eight questions to work through, in order, before you buy any UK pet insurance policy. Get them right and the right brand for your pet will be obvious. Skip them and you’ll buy on price and discover the gaps at the worst possible moment.

1. Cover type: lifetime, annual, maximum benefit, or accident-only?

This is the structural decision that determines everything else. Lifetime is the only cover that pays for chronic conditions for life. Annual (time-limited) pays for 12 months and then permanently excludes the condition. Maximum benefit gives a one-time pot per condition with no time limit. Accident-only excludes every illness.

For any young, healthy pet you intend to keep for life, lifetime is the right answer in nine cases out of ten. The other one (genuinely catastrophic-savings owner with high tolerance for variable spend) is rare.

Read lifetime vs annual vs accident-only before going further.

2. What vet fee limit do you actually need?

The headline marketing limit is annual. The question is what fits the worst case for your pet.

Approximate worst-case bills in 2026 UK vet pricing:

• TPLO surgery for cruciate rupture: £3,500 to £5,500 per knee
• Six-month chemotherapy protocol for lymphoma: £6,000 to £12,000
• IVDD surgery and rehab in a Dachshund: £6,000 to £9,000
• Cataract surgery in a diabetic dog: £4,000 to £6,000 per eye
• Long-stay ICU for severe pancreatitis: £4,000 to £8,000

A £4,000 vet fee limit is exhausted by a single one of those. £7,000 covers most. £10,000+ is recommended for high-risk breeds (Frenchies, Bulldogs, Goldens, large breeds prone to bone tumours) or anyone with a low tolerance for “out of cover” surprises.

Doubling the vet fee limit typically adds 30% to 50% to the premium, not 100%, so the marginal cost is usually justifiable.

3. What excess and co-payment are you signing up to?

The excess is the fixed amount you pay per condition, per policy year. The co-payment is the percentage of each bill you also pay, usually introduced when your pet hits 8 (dogs) or 10 (cats).

Combinations to look for:

• Best: £75 to £150 excess, no co-payment, no automatic increase as the pet ages
• Acceptable: £150 to £200 excess, no co-payment, or £100 excess with 10% co-payment from age 10
• Avoid: 20% co-payment, 25% co-payment, co-payment from age 6, or excess north of £250

Why this matters: a £6,000 claim with £200 excess and 20% co-pay leaves you £1,360 out of pocket. With £100 excess and no co-pay, the same claim leaves you £100 out of pocket. The premium difference between those two policies is rarely more than £20 a month, which is £240 a year.

4. Is dental properly covered?

Three categories of dental cover, broadly:

• Dental from injury (covered by everyone). A fractured tooth, jaw injury, or oral foreign body falls here.
• Dental disease (covered by some, often with conditions). Periodontal disease, gingivitis, tooth root abscesses. Requires you to keep up with annual dental check-ups.
• Routine cleaning (covered by no one).

For a young pet, the dental disease question is genuinely important. Most pets develop some level of periodontal disease by age 6. A full dental treatment with extractions can run £600 to £1,500. A policy that excludes dental disease will not pay any of that.

Brands that handle dental well in our testing: ManyPets, Petplan Covered For Life, Napo, Agria. Brands that exclude dental disease entirely: most accident-only and budget annual policies.

5. Is behavioural therapy covered?

Behavioural problems are a real and growing area. Separation anxiety, noise phobias, reactive behaviour, and compulsive disorders all benefit from referral to a clinical animal behaviourist (typically £400 to £1,200 for a full work-up plus follow-up).

Modern UK insurers (ManyPets, Napo, Waggel, Agria, Petplan Covered For Life) include behavioural therapy by a vet-referred clinical animal behaviourist, with inner annual limits typically £500 to £2,500. Older or budget policies exclude it entirely.

Don’t add this on at age 6 when you suddenly need it. Build it in at start.

6. Is complementary therapy covered?

Hydrotherapy after orthopaedic surgery, physiotherapy for arthritis, acupuncture for chronic pain. These are mainstream parts of veterinary care now. A 12-week post-op hydro programme is typically £600 to £1,200.

Modern lifetime policies include complementary therapy when vet-referred, with annual limits of £500 to £1,500. Older policies often exclude it. Worth checking.

7. How does the claims process actually work?

Three things to ask:

Direct vet pay or reimbursement? Direct vet pay (the insurer pays the vet directly) means you only handle the excess and any co-payment at the desk. Reimbursement means you front the bill and claim it back. For a £6,000 surgery, the difference matters.

Average claims processing time? Reputable insurers process straightforward claims in 5 to 14 working days. Anything routinely slower than that is a flag.

App-based claims or paper forms? Modern insurers (ManyPets, Napo, Waggel, Everypaw) handle claims through an app with photo upload of the invoice. Older insurers still use paper forms or PDF email. The app route is faster.

8. What does renewal pricing look like?

The first-year premium is the marketing number. The renewal pricing is the real cost of the relationship. Most UK insurers raise renewal premiums by 15% to 30% a year for older pets even with no claims, because they price assuming the pet is statistically more likely to claim.

The insurers with the most stable renewal pricing in our long-term tracking: Petplan Covered For Life, Agria, Animal Friends. The insurers with the steepest renewal climbs: many price-comparison-focused brands that win on first-year cost and recover margin at renewal.

Ask before buying: “What was the average renewal premium increase for a healthy 5-year-old dog at this address in the last 12 months?” Most will give you a range. The ones that won’t are the ones to be wary of.

Putting it together

Work the eight questions in order. The first three (cover type, vet fee limit, excess) eliminate roughly two-thirds of the market. Questions 4 to 6 (dental, behavioural, complementary) narrow the remainder to a shortlist of five or six. Questions 7 and 8 (claims process and renewal pricing) pick the winner.
