Pet Insurance for Pre-Existing Conditions UK
Most UK pet insurers exclude pre-existing conditions — but you can still get cover for everything else, and some conditions may eventually become covered again. Here's the honest picture.
Key Takeaways
- ✓No UK insurer covers a condition your pet already has at point of sign-up.
- ✓You can still insure your pet — the pre-existing condition is simply excluded.
- ✓Moratorium policies may reinstate cover for a condition after 2 symptom-free years.
- ✓Declaration-based policies explicitly list what's excluded — more certainty at claim time.
- ✓Structural conditions (hip dysplasia, luxating patella) are almost never reinstated.
The Direct Answer
No UK pet insurer will cover a condition your pet already has. This is true across all insurers — Agria, Petplan, ManyPets, John Lewis, and every other UK provider. Pre-existing condition exclusions are standard across the industry and are not a loophole or unfair practice — they reflect how insurance risk works.
However, this doesn't mean insurance is useless for a pet with health issues. Your pet is still insurable — they're just insured for everything except the pre-existing condition. A dog with a known hip problem can still be insured against cancer, heart disease, cruciate injuries to the other leg, gastrointestinal problems, and hundreds of other conditions.
What Counts as a Pre-Existing Condition?
The definition is broader than many owners realise. A pre-existing condition includes any:
- !Illness or injury your pet had before the policy start date
- !Condition your pet was examined for — even without a formal diagnosis
- !Symptom noted in the vet records at any point before you signed up
- !Condition that developed during the policy waiting period (typically 14 days for illness)
- !Related or connected condition — e.g., arthritis in the opposite hip if one hip has been treated
Moratorium vs Declaration-Based Exclusions
UK insurers handle pre-existing conditions in two main ways. Which approach you choose affects both your premiums and your certainty at claim time.
| Approach | How It Works | Pros | Cons |
|---|---|---|---|
| Moratorium (most common) | You don't declare conditions upfront. If a claim arises, the insurer reviews vet records and excludes anything in the last 2–5 years. | Simpler to apply. Conditions CAN be reinstated after 2 symptom-free years. | Uncertainty — you don't know what's excluded until you claim. Risk of surprise rejections. |
| Declaration-based | You declare all health history upfront. Insurer specifies exactly what's excluded before cover starts. | Certainty — you know your exclusions from day one. No nasty surprises at claim time. | More admin upfront. Exclusions are fixed and rarely reinstated. |
Which UK Insurers Use Which Approach?
| Insurer | Approach | Moratorium Period |
|---|---|---|
| Agria Pet Insurance | Moratorium | 2 years symptom & treatment-free |
| Petplan | Moratorium | 2 years symptom & treatment-free |
| ManyPets (ManyPets) | Moratorium | 2 years symptom & treatment-free |
| John Lewis Finance | Declaration-based | N/A — exclusions listed at inception |
| Animal Friends | Moratorium | 2 years symptom & treatment-free |
| Waggel | Declaration-based | N/A |
Conditions That Are Almost Never Reinstated
Even under moratorium policies, some conditions are structural or hereditary and are considered permanent exclusions regardless of symptom-free periods:
- ✗Hip dysplasia (and related osteoarthritis)
- ✗Elbow dysplasia
- ✗Luxating patella
- ✗Brachycephalic Obstructive Airway Syndrome (BOAS) in flat-faced breeds
- ✗Intervertebral disc disease (IVDD) in predisposed breeds (Dachshunds, Shih Tzus)
- ✗Hereditary eye conditions (PRA, cataracts)
Our Recommendation
If your pet already has a diagnosed condition, the most important thing is to still get cover — for everything else. Don't assume insurance is worthless because one condition is excluded. Compare policies on the basis of what they do cover, not just the exclusion.
If your pet is young and healthy right now, get lifetime cover immediately — before any conditions develop. The moratorium window works in your favour: conditions that arise after you have cover are covered by the active policy.
❓ Frequently Asked Questions
Can I get pet insurance for a dog with pre-existing conditions UK?
Yes — the pre-existing condition will be excluded, but you can still insure your pet for all other conditions. Most UK insurers use a moratorium approach, meaning the excluded condition could become eligible for cover again after 2 consecutive symptom-free years.
What counts as a pre-existing condition in pet insurance UK?
Any illness, injury, or symptom your pet had before the policy start date — or during the waiting period. This includes conditions noted in vet records even without a formal diagnosis. Related conditions (e.g. arthritis in the leg adjacent to a known injury) may also be excluded.
Will pet insurance cover a condition that came back after 2 years?
Under a moratorium policy, yes — if your pet has been completely symptom-free and received no treatment or medication for the condition for 24 consecutive months, it may become eligible for cover on future claims. Contact your insurer to confirm before assuming coverage.
Should I disclose all health history when getting pet insurance?
Yes, always — this is a legal requirement under insurance law. Failure to disclose known conditions constitutes non-disclosure and can result in claims being denied or your policy being voided entirely. Honesty protects you.
Is it worth insuring a dog with hip dysplasia?
Yes. Hip dysplasia affects one joint system. Cancer, heart disease, diabetes, cruciate ligament injuries (opposite leg), gastrointestinal problems, and hundreds of other conditions are entirely unrelated. Insurance still protects against the vast majority of what could go wrong.
