Quick answer: Switching pet insurance is usually safe if your pet has never had anything more than routine care, and it can save you money at renewal. It is usually a mistake if your pet has an ongoing or recurring condition, because any condition your pet has been treated for will normally be excluded by the new insurer as pre-existing. Before you switch, get in writing what the new insurer would exclude, check its waiting period, and never cancel your old policy until the new one has started.
A big renewal price is the most common reason owners think about moving insurer. This guide shows when switching makes sense, the traps that catch people out and how to switch without a gap in cover.
The main risk: pre-existing conditions
A new policy is a new contract. Your new insurer will look at your pet’s vet history and exclude anything that has already happened. As Scratch & Patch explains, a condition your pet developed while insured with your current provider may be treated as pre-existing when you take out a new policy.
On a lifetime policy, that is exactly the cover you have been paying for. If your dog has arthritis and your current insurer pays for it every year, a new insurer will almost certainly exclude it for good. Our guide to pet insurance and pre-existing conditions explains how insurers decide.
Should you switch? A quick check
| Your pet’s situation | Switching is… | Why |
|---|---|---|
| Young, only routine vet visits | Usually safe | Nothing to exclude, so you can compare freely |
| Had a one-off problem that fully resolved | Possible, with care | Ask the new insurer in writing whether it will exclude it |
| Has an ongoing, recurring or lifelong condition | Usually a bad idea | You lose cover for the condition most likely to cost you money |
| Is older, with any health history | Rarely worth it | New exclusions, age limits and co-payments; see pet insurance for older dogs |
Waiting periods start again
Most new policies won’t cover illness for the first days. Waggel, for example, applies a 14-day warm-up period, and conditions that appear in that time may later be treated as pre-existing.
Some insurers remove the waiting period for customers switching from another insurer, as long as there is no gap in cover:
- ManyPets waives its 14-day waiting period if you switch straight from an insurer you’ve been with for 12 months or more, excluding bilateral conditions and pregnancy.
- Sainsbury’s Money waives its initial 14-day exclusion period if you are currently insured elsewhere with no gap, though you may need to show evidence of your previous policy.
These terms can change, so confirm them before you buy.
Don’t overlap policies
It can seem sensible to run both policies for a couple of weeks to cover the waiting period. ManyPets warns against it: if you claim during an overlap, it can void both policies. Line up the dates instead, so the new policy starts the day the old one ends.
How to switch pet insurance safely, step by step
- Get your pet’s vet history. Ask your practice for the clinical notes so you know what a new insurer will see.
- Get quotes and compare like for like. Match the policy type, vet fee limit, excess and co-payment, not just the price. See lifetime vs time-limited vs maximum benefit cover and excess and co-payment explained.
- Ask in writing what would be excluded. Name any past condition and get a clear answer before you commit.
- Check the waiting period and whether it is waived for switchers.
- Send any outstanding claims to your current insurer first. Treatment that happened while your old policy was active is its responsibility.
- Set the new start date to the day your old policy ends. Switching at renewal is simplest.
- Cancel the old policy or turn off auto-renewal only once the new documents have arrived.
- Read the new documents in the cooling-off period. Under UK consumer law you have 14 days from the start of the policy, or from receiving the documents if later, to cancel for a refund.
Switching mid-policy
You can usually cancel before the end of the policy year. If you paid annually, most insurers refund the unused portion, but if you have made a claim during the year, the insurer may keep part or all of the refund. Some policies also require notice or charge a cancellation fee. In most cases it is simpler and cheaper to switch at renewal.
Alternatives to switching
If the main problem is price and your pet has a health history, try these first:
- Raise your voluntary excess to lower the premium without losing cover.
- Pay annually if you can; monthly instalments can include interest or fees.
- Review the vet fee limit carefully; see how much vet fee cover you need.
- Ask your insurer to explain the increase. Our guide on why pet insurance goes up covers the usual reasons.
Frequently asked questions
Can I switch pet insurance if my pet has a condition?
Yes, but the new insurer will usually exclude that condition, and possibly related ones. For many owners that makes switching a bad deal.
Does switching pet insurance affect my claims history?
The claims history itself stays with your old insurer, but your new insurer can see your pet’s medical history and will use it to decide what to exclude.
When is the best time to switch?
At renewal, with the new policy starting the day the old one ends. It avoids cancellation fees and refund problems.
Will I be covered straight away?
Not always. Most new policies have a waiting period for illness, although some insurers waive it for customers switching with continuous cover.
How do I know what a new policy will cost?
Get quotes for your own pet. Our guide to pet insurance cost in the UK explains what drives the price.
Key takeaways
- Switching is usually safe for young, healthy pets and risky for pets with a health history.
- Past conditions normally become exclusions with a new insurer.
- Waiting periods restart, though some insurers waive them for switchers.
- Never overlap policies and never cancel before the new cover starts.
