Get cover for pets with pre-existing conditions

What is a pre-existing condition for pet insurance?

A pre-existing condition in pet insurance terms is likely to be an illness, injury, or symptom your pet showed signs of, was diagnosed with, or received treatment for before your latest policy started.

It isn't necessarily something that was diagnosed by your vet before you bought insurance. It can include signs or symptoms of an illness or injury that existed before your cover began.

Most insurers will consider a condition to be pre-existing if your pet:

  • Was showing symptoms of a condition before the policy started,

    such as limping, itching, vomiting, or ongoing ear irritation

  • Has already been diagnosed by a vet before you took out the policy

    with a skin allergy, diabetes, arthritis, or heart condition, for example

  • Has a condition relating to a previous injury or illness,

    such as ongoing joint problems following a ligament injury

Can I get pet insurance for pre-existing conditions?

Yes, you can often get pet insurance if your pet has a pre-existing condition

With standard pet insurance, your insurer is unlikely to pay for treatment related to the existing condition, though should pay out for unrelated health issues. Some insurers may consider covering a previous condition if no treatment has been needed for a specified period of time.

However, if you want the condition itself to be covered, you will most likely need to take out a specialist policy.

Even these policies may still have exclusions or limits on how much you can claim, so it’s important to understand these restrictions, checking if any elements of your pet’s future care are still excluded. Also be aware that these types of policies tend to be more expensive.

Note that different insurers may vary in how they assess medical history and some may also include recurring or related conditions within their definition of pre-existing. Always check the policy wording carefully so you understand how your insurer defines pre-existing conditions before buying or switching cover.

What can pet insurance for pre-existing conditions cover?

Chronic or long-term conditions

Conditions requiring ongoing medication, treatment or monitoring are more likely to need specialist cover, such as arthritis, diabetes, epilepsy or asthma.

Recurring conditions

A condition that has happened more than once, or where symptoms continue to come and go, such as recurring ear infections, skin problems or allergies, may be treated as pre-existing even if your pet isn't currently being treated.

Hereditary conditions

Some insurers may restrict cover for conditions that are inherited or present from birth, such as hip dysplasia or certain conditions common to specific dog or cat breeds.

Bilateral conditions

Some conditions, like cruciate ligament injuries, can affect both sides of your pet’s body, or a new injury could be deemed related to an existing condition, and this may not be covered under standard insurance.

Undiagnosed conditions

If you sought advice from the vet in the past for a particular issue or set of symptoms, even if they didn’t give a formal diagnosis, some insurers may judge the ‘new’ condition as pre-existing.

How does pre-existing pet insurance work?

It works in a similar way to standard pet insurance, but may provide cover for some existing health conditions that standard policies would typically exclude:

  • Tell your insurer about your pet

    Give your insurer details about your pet and its health, including any pre-existing conditions, making sure you understand what conditions are covered.

  • Select cover that meets your needs

    Insurers offer a broad range of cover from the most comprehensive lifetime cover to the lowest cost accident-only policy. Pick the one that suits you and your pet best.

  • Waiting periods may apply

    Many policies include a short waiting period (often around 14 days) before illness cover starts. Any treatment needed during this time usually won’t be covered.

  • Choose how to pay

    Paying for your policy annually can often slightly reduce the cost of your insurance.

  • Know your claim limits

    Claims for pre-existing conditions may be excluded or have lower or separate claim limits than those in standard policies, meaning there may be a cap on how much you can claim each year or per condition.

  • Review when you renew

    Insurers may review premiums, limits, or exclusions at renewal, especially if claims have been made, so check the cover still suits your needs.

How much does pet insurance for pre-existing conditions cost?

The average cost of pet insurance is £23.63^. However, this does not include pets with a pre-existing condition.

Specialist pet insurance for pre-existing conditions is likely to be more expensive – significantly more in some cases.

It depends on factors including your pet's age, breed, medical history and the type of condition they have, as well as your level of cover.

Some breeds are more likely to suffer with certain conditions, and this could push the price up.

How do I get the cheapest pet insurance policy with a pre-existing condition?

Shop around

Each insurer will consider the level of risk differently, as some specialise in older pets or complex histories. With others, the price of insurance for pre-existing conditions can be significantly higher or excluded entirely.

Comparing insurance from a range of providers can help you avoid paying over the odds for insurance while still ensuring the right level of cover.

Check how insurers view the condition

Insurers look closely at how severe the condition is, whether it's ongoing, and how recently symptoms occurred.

Some insurers may consider a condition ‘historic’ if your pet has been symptom-free and hasn't needed treatment for a set period. The criteria vary between insurers, so check the policy carefully.

Check whether the condition is covered

A cheaper policy isn't necessarily better if it excludes the condition your pet already has. Check whether the insurer will cover the condition itself, as well as any related or recurring conditions.

Decide your level of cover

You could opt for a lower level of cover, but be sure to get the coverage your pet needs at a price you can afford.

Increase your excess

This is the amount you agree to pay before the insurer covers the rest of the claim. The higher the excess is, typically the lower your premiums. Just be sure you could pay it if you had to claim.

Check policy limits

Even if all the conditions you’re concerned about are covered, how long this lasts and the maximum amount you can claim per condition can vary between insurers

Understand what's covered

Make sure you understand exactly what is included, particularly whether the pre-existing condition itself is covered.

Check for exclusions for related or recurring conditions, as well as benefits such as vet bills, boarding fees if you're taken ill, third-party liability and advertising costs for missing pets.

Check the excess, claim limits and exclusions, as these can make a cheaper policy more expensive if you need to claim.

Check policy limits

Even if all the conditions you’re concerned about are covered, how long this lasts and the maximum amount you can claim per condition can vary between insurers.

Do I need to declare pre-existing medical conditions?

Yes. You need to declare your pet's pre-existing conditions to your insurance firm and always answer questions about your pet’s medical history accurately. Failing to do so could mean your policy no longer covers you, so your claim could be rejected.

However, that doesn't mean that you will need to tell them every detail of your pet's vet appointments.

Most will want to know of any health problems your pet has had in the past few years, so you don't need to worry about trying to remember every trip you've taken to the vet. Some may only need to know whether your pet has a pre-existing condition without needing you to specify.

Our expert says…

Don’t assume you can’t get cover if your family pet has a medical past, but be prepared for it to cost more than the standard cover.

Always check the small print, regardless of your pet’s health to date, to be sure you are clued up on what is and isn’t covered. And never omit the truth when asked about your pet’s medical history in a bid to save a few pounds, you could end up voiding your cover just when you need it.

Is it worth getting pet insurance for pre-existing conditions?

  • It could be worth it if:

    • You have an older pet: insurance can still help with new illnesses or injuries in an older pet, like cats or dogs, even if existing conditions are excluded

    • Your pet has stable or historic conditions: if your pet has been symptom-free for a long period, some insurers may offer limited cover, which can reduce future vet costs

    • You want protection against high vet bills: even partial cover can help with expensive treatments, medication, prescribed diets or therapies

    • You need peace of mind: insurance can reduce the financial stress if your pet’s condition worsens or they develop unrelated health issues

  • It may not be worth it if:

    • Your pet has an ongoing or chronic condition: if your pet has a long-term condition like arthritis, allergies or hip dysplasia, insurers may exclude it or limit claims, reducing the value of cover

    • Premiums are unaffordable: policies covering pets with medical histories usually cost more, so you need to weigh up the cost of insurance with estimating how much you may pay in vets’ bills

    • If cover is heavily restricted: some policies only cover pre-existing conditions for a short time or up to a low limit, or don’t cover every associated cost, meaning you could still face high vet bills

How long does a pre-existing condition last for pet insurance?

A pre-existing condition doesn’t have a fixed time limit in pet insurance. How long it lasts depends on the insurer and your pet’s medical history.

In general, insurers define a pre-existing condition as any illness or injury your pet showed symptoms of, or received advice, treatment or medication for, before the policy started.

Some may look at a specific period of time and only review any illnesses, treatment or diagnoses your pet had during that time.

Insurers may reconsider whether a condition is pre-existing if your pet has been symptom-free and treatment-free for a set period.

In these cases, the condition may be covered again or the claim limit for it may increase.

However, this usually doesn’t apply to chronic, ongoing or recurring conditions, which are often excluded permanently.

Always check the insurer’s definition and confirm what’s covered before you buy.

Are allergies considered a pre-existing condition for pet insurance?

Allergies are often treated as a pre-existing condition for pet insurance, but this depends on whether they’re ongoing or fully resolved.

If your pet needs regular medication, prescription food or repeat vet visits to manage their allergies, most insurers will class them as a chronic pre-existing condition and are unlikely to offer cover for allergy-related treatment.

However, if your pet had allergy symptoms in the past but has been symptom-free and treatment-free for a set period, some insurers may view the allergy as historic rather than ongoing.

In these cases, limited cover may be available, depending on the insurer’s rules.

Because definitions vary, it’s important to check how each insurer treats allergies and confirm in advance whether past symptoms or treatments would affect cover before you buy a policy.

What’s the difference between pre-existing, hereditary and chronic conditions?

Pet insurers use different terms to describe long-term health conditions, and each can affect whether you’re covered and how much you pay.

Pre-existing conditions are illnesses or injuries your pet had symptoms of, or received advice, treatment or medication for, before the policy started.

These are usually excluded from new policies or only covered in limited circumstances, which can make insurance harder to find or more expensive.

Hereditary conditions are genetic conditions that are more common in certain breeds, such as hip dysplasia in dogs.

Many insurers will cover hereditary conditions, but usually only if you take out the policy before the condition develops. If symptoms appear before cover starts, the condition is likely to be treated as pre-existing and excluded.

Chronic conditions are long-term illnesses that need ongoing or lifetime management, such as diabetes, arthritis or allergies.

Because they often require regular treatment, medication or monitoring, chronic conditions are the hardest to insure. Insurers may exclude them entirely or charge higher premiums to reflect the ongoing cost.

In general, the earlier you insure your pet, before symptoms develop, the more likely you are to get broader cover at a lower cost.

Can I change pet insurance with a pre-existing condition?

Yes, you may be able to change pet insurance even if your pet has a pre-existing condition, but it’s important to compare carefully before switching and don’t cancel an existing policy before you've established exactly what a new policy will cover.

Switching shouldn’t simply be about finding a better price. Also look at other factors including which existing conditions are covered, what is excluded, claim limits, and the level of excess.

If you’ve already made a claim, most new insurers will treat the condition you claimed for as pre-existing.

This usually means it will be excluded from cover, even if it was covered under your previous policy. In many cases, a new insurer won’t match the level of cover you already have for that condition.

That said, switching can still make sense in some situations. Your current insurer may have a limit on how much you can claim per condition or per year, and once that’s reached, further treatment may no longer be covered.

In these cases, a new policy could still offer better value by covering new illnesses or injuries, even if existing conditions are excluded.

When comparing policies, don’t just look at cover for pre-existing conditions. Pet insurance can also include benefits such as third-party liability cover, awareness campaigns and rewards for lost pets, boarding fees if you’re taken ill, and cover for death by accident or illness.

Before switching, always check exclusions carefully and confirm in writing what a new insurer will and won’t cover, especially if your pet has a medical history.

Does pet insurance cover my pet immediately?

No, cover isn’t immediate. Pet insurance policies don’t cover health conditions as soon as you take them out, and most insurers apply a waiting period of around 14 days before cover begins.

During this time, you won’t be able to claim for illnesses or conditions that show symptoms, require treatment or are diagnosed. Some insurers may apply longer waiting periods for specific conditions or types of cover.

The waiting period for accident cover may be shorter.

Always check the policy terms so you understand when cover starts and what is excluded during the waiting period, especially if your pet has a medical history.

What if my pet develops a different condition that could be related to a previous problem?

It depends on the terms of your policy. An insurer may consider a new condition to be related to a previous illness, even if your pet has not been treated for the original condition recently. If it is considered related, treatment for the new condition may be excluded from cover.

For example, if your dog has previously suffered from a joint condition and later develops a problem affecting the same area, your insurer may consider the two conditions connected.

Some policies may provide cover for a related condition if your pet has been free from symptoms or treatment for a specified period, but this varies between insurers. Check the policy's definition of a pre-existing condition and any exclusions for related, recurring or bilateral conditions before buying.

What can I do if I disagree with my insurer's decision about how they define ‘pre-existing’?

If an insurer has classed your pet’s condition as pre-existing, but you disagree, your first step is to make a complaint to the company itself.

Written evidence from your vet could be helpful in supporting your case, as part of a range of evidence which the insurer should look at.

If you don’t get a satisfactory response within eight weeks, and you still believe your insurer is in the wrong, you can take your case to the Financial Ombudsman.

They will investigate and decide whether they feel you have been treated unfairly or not. If they feel you have lost money, they may ask your insurer to put things right and may ask them to pay compensation.

What if I can't afford insurance for my pet's pre-existing condition?

Once you have researched and compared the prices from different insurers, comparing the different types of cover, you may decide that the cost of insurance outweighs the benefits, or that you simply cannot afford to take out a specialist policy.

In that case, you have a few options.

It would be a good idea to build a specific savings pot for your animal’s care. This would give you something to fall back on if you had to pay a vet’s bill.

You should also be honest with your vet as they may be able to suggest a lower-cost or phased treatment plan, as well as writing prescriptions for your pet that you can then use in online pharmacies which may be cheaper than buying directly from the clinic.

If you are still struggling, animal charities may be able to support you. The PDSA, RSPCA and Blue Cross offer free or lower cost care, but you have to meet certain criteria to be eligible. You may also be able to find a local independent charity that can help.
