The short version
- On the insurers we checked, illness waiting periods ranged from 14 to 28 days. Most had no waiting period for accidental injury.
- Longer waiting periods often apply to cruciate ligament conditions (90 days to 6 months on the plans we checked) and some breed-related conditions.
- A condition that first shows signs during a waiting period is commonly treated as pre-existing.
- Some insurers waive the stand-down when a policy is renewed rather than newly taken out.
They are counted to the hour
The Financial Services Complaints Ltd (FSCL) dispute scheme has published a case where a dog became ill about 12 hours before a 21-day illness stand-down ended. The claim for $1,738.90 was declined, and the decline was upheld. FSCL noted that an insurer “is entitled to restrict cover under its policy wording.”
The practical point is to know the exact start time on your certificate, not just the date.
Why insurers use them
Waiting periods stop cover being bought only once a pet is already unwell. The trade-off for owners is that cover is not fully in place on day one, so the timing of starting a policy matters.

- Annual limits, excess and co-paymentThree numbers decide how much of a vet bill comes back to you. They interact, and most people only look at one.
- Pre-existing conditionsWhy a condition your pet already has is usually not covered, and what “already has” means.
- Age limits for starting coverMost policies have a youngest and an oldest age to start. The oldest age is the one that catches people out.
