Best Pet Insurance for Cats with Kidney Disease (UK 2026)
Best Pet Insurance for Cats with Kidney Disease (UK 2026)
Last updated: June 2026
If your cat has already been diagnosed with chronic kidney disease (CKD), that condition is pre-existing and a new standard policy will not cover its treatment. This guide is for owners insuring before kidney problems appear and for anyone assessing how cover would work if an eligible chronic condition develops later.
CKD often requires repeated tests, monitoring and medication. That makes lifetime structure and a sufficient annual limit more important than a low first-year premium. Prescription kidney food is normally excluded and needs a separate household budget.
Key facts
- A new policy will not pay for CKD already diagnosed or showing signs before cover began or during its waiting period.
- Lifetime cover resets eligible limits at renewal, allowing a covered ongoing condition to remain claimable while the policy continues without a gap.
- A higher annual limit creates more room for recurring diagnostics, medication, monitoring and flare-ups.
- Prescription kidney diets are generally excluded as food, even when recommended by a vet.
What CKD management can cost
- Diagnosis and staging: consultation, blood and urine tests, blood-pressure measurement and sometimes imaging can cost around £200 to £600 or more according to UK vet-cost guidance.
- Ongoing monitoring and medication: repeat tests every few months can total several hundred pounds a year, while medicines for blood pressure, phosphate or protein loss may recur for life.
Prescription kidney food is usually not reimbursed because policies generally exclude food and therapeutic diets. Budget for it separately and ask your vet what treatment or diet is clinically appropriate.
Compare lifetime cover and annual limits
Limits depend on the chosen tier, and age-triggered co-payments differ, so confirm both on the current quote.
| Provider | Cover style | Top annual limit | Why it matters for chronic CKD | Excess / co-pay |
|---|---|---|---|---|
| Waggel | Lifetime | Up to £15,000 a year, tiered | Eligible limits reset at renewal; upper tiers provide more headroom | £0 to £350 selectable per condition per year; optional 20% co-pay at any age |
| Petplan | Lifetime, also time-limited | £12,000, with £4,000, £7,000 and £12,000 tiers | Lifetime cover available; claiming alone does not increase the premium | Fixed excess plus automatic 20% co-pay after age 10 |
| ManyPets | Lifetime only | £20,000 on upper tiers | One excess per policy year can suit several claims | One annual excess; mandatory 20% co-pay from age seven |
| Agria | Lifetime only | £20,000, with £3,000, £6,500, £12,500 and £20,000 tiers | No upper joining age for an older cat without prior kidney signs | Fixed excess plus co-insurance set at quote |
| Napo | Lifetime only | £16,000, with £4,000, £8,000, £12,000 and £16,000 tiers | High upper tier for recurring care | £99 per condition per year plus automatic 20% co-pay from age nine |
The insurers and their chronic-care distinctions
Waggel: flexible excess and optional co-payment
Waggel's lifetime limits reset at renewal, and annual tiers rise to £15,000. The selected excess, from £0 to £350, applies per condition per policy year, so after the year's excess has been paid for an eligible kidney condition, further eligible CKD claims that policy year are not charged another excess for that condition.
The 20% co-payment is optional at every age rather than triggered automatically by a birthday. There is no maximum joining age, which can help an older cat that has no kidney signs obtain cover. Conditions are not declared upfront; medical history is reviewed at claim stage. That process does not change eligibility, and existing CKD remains excluded.
Petplan: established lifetime cover
Petplan's lifetime tiers rise to £12,000 a year, alongside a time-limited option. It states that making a claim alone will not raise the premium. An automatic 20% co-payment begins after a cat reaches age 10, so an older cat's owner will contribute a larger share of recurring eligible costs.
ManyPets: one excess per policy year
ManyPets offers lifetime cover only, with upper tiers reaching £15,000 and £20,000. Its single excess for the policy year can suit several claims arising from ongoing care. A mandatory 20% co-payment applies from age seven, which is an important cost for a condition commonly affecting older cats.
Agria: no upper joining age and a high top tier
Agria is lifetime-only, sets no upper joining age and offers annual tiers up to £20,000. That can help an older but kidney-healthy cat obtain cover before signs appear. Its contribution combines a fixed excess and co-insurance set at quote, so compare both parts with simpler excess models.
Napo: a high lifetime limit for recurring care
Napo provides lifetime-only cover with tiers up to £16,000. Its excess is £99 per condition per year, while an automatic 20% co-payment starts at age nine. The top tier offers room for monitoring and medicines, but the age-triggered contribution increases the owner's share of each eligible bill.
How a CKD claim works when the condition is eligible
If kidney disease first shows signs after cover starts and after the waiting period, an eligible lifetime policy may pay for the investigations and treatment listed in its wording. This can include consultations, blood and urine tests, blood-pressure checks, imaging, medication and clinically necessary monitoring. The insurer will review the medical record to confirm that earlier symptoms did not make the condition pre-existing.
The annual limit is shared with other eligible veterinary claims unless the wording says otherwise. A cat that uses £3,000 for CKD care and £2,000 for an unrelated injury has used £5,000 of a single annual allowance. If the limit is exhausted, the owner pays further bills until renewal. On a continuously renewed lifetime policy, the allowance then resets, although the excess may be charged again for the new policy year.
Costs that may remain with the owner
Cover does not make treatment free. You may still pay a fixed excess, a senior co-payment, anything above the annual limit and items specifically excluded. Prescription kidney diets are usually treated as food rather than medicine. Routine health checks, vaccinations, supplements and non-veterinary purchases are also normally outside the policy.
A worked example shows why the contribution matters. On a £1,200 eligible bill, a £100 excess plus a 20% co-payment can leave a substantial balance for the owner, with the exact calculation set by the policy wording. Ask for an illustration and budget for several claims, not just one appointment.
Why changing insurer after symptoms appear is risky
Switching does not transfer cover for an existing illness. A new provider can treat earlier increased thirst, weight loss, abnormal urine results or kidney investigations as pre-existing even if CKD was diagnosed later. Keeping an existing lifetime policy may preserve cover for an eligible condition, subject to renewal terms, while moving for a cheaper premium may lose it.
Before renewal, compare the new premium, annual limit, excess and co-payment with the likely value of continued CKD cover. Also check inner limits for complementary treatment and whether the insurer can pay the vet directly. Do not cancel the old policy until the consequences for ongoing claims are clear.
What to check for a chronic condition
- Lifetime structure. Confirm that eligible limits reset at every renewal, allowing a covered condition to remain claimable from one policy year to the next while cover remains continuous.
- Annual limit. Select enough headroom for repeat blood and urine tests, medication, consultations and a possible bad year, while recognising that a higher tier usually costs more.
- Pre-existing and waiting-period rules. CKD present or showing signs before cover, or during the initial waiting period, will normally be excluded. Waggel's waiting period is 14 days, and its claim-stage history review does not convert earlier disease into covered disease.
- Prescription-food exclusion. Kidney diets are generally treated as food rather than insured treatment, so include them in the ongoing budget outside any annual vet-fee allowance.
How recurring CKD claims use the policy
Lifetime cover does not create an unlimited fund. Each policy year has a selected allowance, and eligible consultations, blood tests, urine tests, imaging, medication and monitoring draw down that year's figure. At renewal, the allowance resets if cover continues, but the premium and terms can change. An inner limit for a particular benefit can also be lower than the headline vet-fee limit.
The owner's contribution depends on the excess model. A per-condition annual excess is normally paid once for that eligible condition in the policy year, whereas one annual excess may cover claims more broadly. A percentage co-payment then leaves the owner responsible for part of eligible costs after the excess is applied according to the wording. For repeated CKD bills, a 20% contribution can become significant even where the annual limit is high.
Before choosing a tier, compare the cost of initial diagnostics with a full year of stable management and the possibility of a more expensive flare-up. The £200 to £600 diagnostic range is only an indication, and repeat tests plus medication can add several hundred pounds over a year. A higher limit offers more room but usually costs more, so the useful choice is the highest sustainable level rather than the largest advertised number at any price.
Keep clinical records and invoices together, and submit claims according to the provider's process. A claim-stage medical-history review may identify blood results or symptoms predating cover. That review cannot make existing CKD eligible, but a policy can still protect against unrelated new illness and injury. Never delay testing or treatment to influence insurance eligibility; decisions about the cat's health belong with the vet.
Frequently asked questions
Can I insure a cat already diagnosed with kidney disease?
You can usually buy insurance for other risks, but the existing kidney disease will be excluded. A new policy may still cover unrelated illnesses or injuries arising later, subject to its waiting period, terms and exclusions.
Does pet insurance cover CKD treatment?
A comprehensive lifetime policy can cover eligible kidney disease first arising after cover and the waiting period. Subject to the annual limit and excess, this may include diagnostic work, blood and urine tests, medication and ongoing monitoring. Accident-only insurance will not cover an illness developing over time.
Waggel is FCA-regulated and its policies are underwritten by Red Sands Insurance Company (Europe) Limited.
