Does Pet Insurance Cover Pre-Existing Conditions?

What is a Pre-Existing Condition for Pet Insurance?
Broadly speaking, a pre-existing condition for pet insurance is an injury or illness that occurred or showed signs before your pet insurance becomes effective. It's important to note that policies often don't become effective right away—that is, a new pet insurance policy officially starts after an initial waiting period that can last for days or weeks and usually differs for accidents vs. illnesses. As a result, an injury or illness is considered to be pre-existing if it affected your pet:
- Before you purchased the policy, or
- During the initial accident or illness waiting period, as appropriate
Additionally, an injury or illness may be considered pre-existing if it is "related to, caused by or shows the same signs of" another previous injury or illness. For instance, bilateral conditions (conditions that occur to a body part of which your pet has a second, such as an ear, eye or hip) are typically treated as one condition by insurers. For example, a previous left ear infection could exclude cover for infections in both ears (i.e., all ear infections would be considered pre-existing).
Does Pet Insurance Typically Cover Pre-Existing Conditions?
The vast majority of UK pet insurance companies do not cover pre-existing medical conditions. If your pet has a pre-existing condition, most companies will either refuse to insure your pet or offer cover that excludes treatment related to the condition. As a result, customers may think they're trapped with the same insurer, unable to change even if faced with rising, higher-than-expected premiums.
That said, we're very glad to report that a few pet insurance companies offer cover for pre-existing conditions in the UK, and hope more follow suit.
Why are pre-existing conditions restricted on pet insurance? If pet insurance companies covered pre-existing illnesses and injuries without restriction, then pet owners might be tempted to keep their pet uninsured until an injury or illness occurred. In that situation, however, insurance companies would surely suffer financially and premiums would rise for all pet owners. By setting some rules around pre-existing conditions, pet insurance premiums are kept lower for everyone.
Does any Pet Insurance cover Pre-Existing Conditions?
As of 2026, we have identified two primary UK pet insurance providers that offer specialized cover for pre-existing conditions, provided your pet has been symptom or treatment-free for a set period (usually three months to two years depending on the condition). These providers—ManyPets and Petgevity (formerly Petsure)—are the current market leaders in offering protection for pets with medical histories.
Note that both Lifetime Pet Cover and Muddy Paws (formerly VetsMediCover) have shifted their underwriting focus and no longer offer dedicated cover for new pre-existing condition applications in the 2026 market.
ManyPets pet insurance remains a standout option in 2026 for its 'Pre-existing' policy, which is specifically designed to cover conditions that have been stable (no treatment, medication, or advice) for at least three months.
Petgevity (previously Petsure) is the primary alternative, utilizing a sophisticated online medical screening system to assess your pet’s unique history. By answering a series of health questions, you can often secure cover for chronic or historic conditions that standard insurers would exclude entirely. We recommend checking both providers, as their 'waiting periods' and condition definitions can vary significantly.
