Bertie Editorial · Updated 27 July 2026
Comparing pet insurance properly is easier than it looks. Six lines in the documents do nearly all the deciding, and an hour with them beats any amount of scrolling. The premium is real and easy to sort by, but it just isn’t where the differences between policies live.
We spend our working days around insurance products, and this is the comparison we’d run for our own dogs, in the order the lines will actually matter to you.
1. Policy type, before anything else
Lifetime, time-limited, maximum benefit or accident-only. This one choice outweighs everything below combined, because it decides whether chronic conditions, the expensive kind, stay covered. It has its own guide, so settle it first and then compare only within the type you chose. Once you’re comparing like with like, everything else on this list gets much easier.
2. The annual limit, and its shape
Two policies can both say “£7,000 a year” and behave completely differently. Per condition, per year is the strong shape, because each problem gets its own refilling pot. For scale, the average claim came to £685 in 2024 according to the Association of British Insurers, but limits exist for the bad years, not the average ones. One shared pot across all conditions runs down faster in a bad year with two problems. Whatever the number, picture a realistic bad year, say surgery plus months of aftercare on one condition, and check it would cope.
3. The sub-limits, where policies quietly diverge
The headline limit gets the marketing, but the sub-limits decide claims, and they’re quick to check once you know where to look.
- Complementary treatment (physiotherapy and hydrotherapy) varies enormously between policies, and it matters for exactly the conditions in our health library.
- Dental is often accident-only unless stated, and dental illness is common.
- Diagnostics like MRI and CT scans are four-figure items, and some policies cap them separately.
- Death, boarding and third-party liability are the smaller print, and occasionally valuable.
4. Excess structure, especially with age
A flat excess per condition per year is simple and fine, and choosing a higher voluntary excess is a perfectly good way to bring the premium down if you can absorb small bills. The one to spot early is the percentage co-payment that some policies add once the pet passes a certain age, commonly worded as the excess plus 20 per cent of the remaining bill. Found now, it’s just a factor in your comparison. Found at claim time, it’s the biggest number on the page. Two minutes with the policy document settles it.
5. Exclusions and definitions
The pre-existing conditions rules do the heavy lifting here, and they differ between insurers more than people expect, from lookback windows to bilateral clauses to how signs and symptoms are defined. Also worth a glance are the waiting periods at the start of the policy, any breed-specific exclusions, and what the policy asks of you, like keeping vaccinations current, for cover to hold.
6. Renewal behaviour, the hardest to see
A lifetime policy is a multi-year relationship, and its value depends on premiums you can’t see yet. You can still read the signals. Look at how the insurer is rated for renewals and claims by existing customers, whether the excess or co-payment changes with age by design, and how long they’ve been in the pet market. Lifetime cover works by you happily staying for the whole of your pet’s life, so an insurer with a good renewal reputation is worth a few pounds more at the start.
Where should you run your quotes?
No single comparison site covers the whole market, and a few insurers don’t appear on any of them, so the thorough version takes two or three stops. This is the round we’d do:
| Where | Worth knowing |
|---|---|
| MoneySuperMarket | One of the biggest panels, good multi-pet quotes |
| Compare the Market | Big panel, but doesn’t do multi-pet quotes |
| Confused.com | Solid panel, worth the third data point |
| Go.Compare | Fourth opinion if prices are varying wildly |
| Direct-only insurers | Some well-known names don’t appear on comparison sites at all, so check one or two insurers directly before deciding |
Treat every result as shortlist material, not a verdict. The documents still decide, which is what the six lines above are for.
None of these links currently pays Bertie anything. If that ever changes, the links will be clearly marked, as our editorial standards promise.
The honest workflow
Decide the type. Shortlist three or four policies of that type, using a comparison site for the list and nothing more.
Then download the actual policy documents. That’s the whole trick. Read them against the six lines above, with your pet’s breed and your worst plausible year in mind. Then buy while your pet is young and the history is clean, and hold your nerve at renewal after any diagnosis, for the reasons the pre-existing guide explains.
That’s the whole method. An hour of reading, once, and it keeps paying you back at every renewal for the rest of your pet’s life.

Your questions, answered
- Are comparison sites a good way to buy pet insurance?
- They are a good way to build a shortlist and a poor way to make the final choice, because they sort by premium while the real differences live in the policy documents. Use them to find candidates, then compare the actual limits, exclusions and excess structures yourself before buying. Note also that some insurers do not appear on comparison sites at all.
- Why is one policy half the price of another?
- Usually because it is a different product wearing the same name: time-limited rather than lifetime cover, a smaller annual limit, a shared pot rather than per-condition limits, a higher excess, or a co-payment percentage. Cheaper is fine when you know which of those made it cheaper and you accept the trade. Cheaper as a surprise is how bad claim stories start.
- Should I just self-insure by saving instead?
- It works until it doesn't: savings handle routine costs and one modest incident, but the point of insurance is the outlier, a surgery-plus-complications year that can run into five figures, arriving before the savings pot has had time to grow. Honest middle ground: insure against the outliers with a decent lifetime policy and self-fund the small stuff via a higher excess, which also lowers the premium.
