When choosing dog insurance, your biggest decision is between lifetime and time-limited cover. Pick the wrong one, and you could end up facing thousands in vet bills that you thought were covered. The difference matters more than most dog owners realise.
Vet costs are rising sharply across the UK. A routine injury can easily run into hundreds of pounds, while serious conditions like arthritis treatment can cost over £2,000, an MRI scan can hit £2,000, and surgery for something like a fractured femur can reach £8,000 or more.[1] Practices in the South East, including Kent, are often towards the upper end of these ranges.
Time-limited policies look attractive because they're cheaper upfront. But they come with a catch that can leave your dog uninsured for chronic conditions. Lifetime policies cost more each month but keep covering your dog year after year, no matter what health problems develop.
This guide breaks down exactly what each type of policy offers, where the hidden traps are, and which option makes sense for your dog. For local pet insurance guidance specific to Kent, see our Pet Insurance in Folkestone guide.

This article provides general information and educational guidance only. It is not regulated financial advice, and we are not qualified to provide personalised recommendations about insurance products. Pet insurance policies vary significantly between providers in terms of cover levels, exclusions, pricing, and terms. Before making any decisions about your pet insurance, you should carefully read your policy documents, compare multiple providers, and consider seeking advice from a qualified, FCA-regulated insurance adviser who can assess your individual circumstances. Always verify current terms, conditions, and pricing directly with insurers.
Time-limited insurance covers each condition for a maximum of 12 months from when it starts, or up to a set amount of money, whichever comes first. Once you hit that 12-month mark or spend the limit, that specific condition is no longer covered. Ever.
Think of it like a voucher with an expiry date. You can use it for a year, but when it runs out, you're on your own.
The 12-month period applies to each individual condition, not to your policy as a whole. If your dog develops arthritis, the clock starts ticking from the first sign of symptoms or the first treatment visit. Keep your policy renewed during that year, and you're covered. But once those 12 months are up, any further arthritis treatment comes out of your pocket.
Here's where it gets messy. Different insurers calculate the start date differently. Some count from the first clinical signs, others from the first vet visit. That ambiguity can cut your coverage short without you realising it.
Time-limited policies are fine for one-off injuries. Your dog tears a ligament, gets treatment, recovers fully. The policy pays out, everyone's happy.
But chronic conditions are a different story. Diabetes, arthritis, heart problems, allergies—these need ongoing treatment. With a time-limited policy, you get 12 months of coverage, then you're covering all future treatment yourself. And because it's now a pre-existing condition, no other insurer will touch it.
You're locked in, paying for all treatment out of pocket for potentially years.
Many time-limited policies treat conditions affecting different body parts as the same condition. Your dog gets an ear infection in the left ear. Six months later, the right ear gets infected. Most insurers will count both as one condition, so the 12-month clock covers both ears, not each one separately.
This catches people out. You assume you have fresh coverage for a new problem, but the insurer disagrees.
Time-limited policies are a common source of complaints to the Financial Ombudsman Service.[2] Dog owners think they're covered, only to find out that their 12 months ran out months ago, or that the insurer calculated the start date differently than expected.
The cheaper monthly premium seems great until you're facing a big bill with no coverage.
The fundamental difference comes down to ongoing coverage. Time-limited policies cover each condition for a maximum of 12 months, then exclude it permanently. Lifetime policies reset your vet fee limit annually and keep covering all conditions—including chronic ones—as long as you renew.
Here's what that means in practice:
For a dog with arthritis, time-limited cover pays out for the first year of treatment—maybe £2,000–£3,000. After that, you're paying £1,500+ annually yourself. Lifetime cover keeps paying for that arthritis treatment every year, within your annual limit.
Lifetime policies cover your dog for ongoing conditions throughout their life, as long as you keep renewing the policy each year. The vet fee limit resets every time you renew, so chronic conditions stay covered year after year.[3]
Think of it like a subscription that refreshes annually. Each renewal gives you a fresh pot of money to cover vet bills, including treatment for conditions that started years ago.
Let's say your policy has a £7,000 annual vet fee limit. Your dog develops arthritis and needs £3,000 worth of treatment in year one. You claim that £3,000, and you still have £4,000 left for any other conditions that year.
When you renew for year two, your limit resets to £7,000. The arthritis is still covered, so if your dog needs another £3,000 in treatment, you're covered again. This continues every year as long as you keep the policy active.
Lifetime cover is designed for conditions that need ongoing management. Arthritis, diabetes, heart problems, skin allergies, epilepsy—all the things that require regular medication, check-ups, or specialist care.
Without lifetime cover, you'd be paying for all this treatment yourself once your time-limited policy expires. That can mean thousands of pounds a year for the rest of your dog's life.
Most lifetime policies include more than just vet fee cover. You'll typically get third-party liability cover (if your dog causes an accident or injury), death benefits, and sometimes cover for theft or loss.
The exact extras vary by insurer, but lifetime policies generally offer the most comprehensive package.
A pre-existing condition is any illness or injury that showed signs before your new policy started or during the waiting period. Once something counts as pre-existing, no insurer will cover treatment for it. This rule applies across the entire industry.
Let's say your dog develops recurring ear infections. Your time-limited policy covers it for 12 months, then stops. You shop around for a new policy, hoping to get coverage again.
Every insurer you approach will ask about your dog's medical history. When you mention the ear infections, they'll classify them as pre-existing. Your new policy won't cover any future ear problems. You're stuck paying for treatment yourself.
This applies to minor conditions too. Allergies, skin problems, digestive issues—once they're on your dog's record, switching insurers means losing coverage for those conditions.
The best time to get lifetime insurance is when your dog is young and healthy. Before anything goes wrong. Once a condition develops, your options narrow dramatically.
If you start with a time-limited policy to save money, you're gambling that your dog won't develop any chronic conditions during that first year. If they do, you'll either need to switch to a lifetime policy with that new insurer (and pay whatever premium they charge) or keep paying out of pocket.
Starting with lifetime cover from day one means you're protected no matter what develops. You don't have to worry about losing coverage or being unable to switch.
Some dog owners assume they can upgrade from time-limited to lifetime cover with the same insurer. While that's sometimes possible, the insurer will still treat anything diagnosed under the time-limited policy as pre-existing when you switch to lifetime.
You might get lifetime cover, but not for the conditions that actually need it.
Time-limited policies cost significantly less than lifetime policies—sometimes 20% to 50% cheaper. That price gap is tempting, but it's worth understanding what you're trading off.[4]
For a young, healthy mixed breed dog, time-limited policies typically start around £10-£12 per month. Lifetime cover for the same dog might cost £12-£15 per month.
The difference seems small at first. Over a year, that's maybe £50-£80 more for lifetime cover. But the coverage gap is huge.
Both types of policy get more expensive as your dog gets older. Dogs over seven years old are more likely to develop age-related conditions like arthritis, kidney disease, or heart problems. Insurers adjust premiums to reflect that risk.
Premiums can easily double by the time your dog reaches eight or nine years old. Some insurers won't even offer new lifetime policies to dogs over a certain age—usually around eight years.
If you've had lifetime cover since puppyhood, you can keep renewing it. But if you're trying to switch from time-limited to lifetime when your dog is older, you might not have that option.
If the monthly cost feels steep, you have options to bring it down:
These adjustments can make lifetime cover more affordable without giving up the long-term protection. For more strategies on managing insurance costs effectively, see our guide on cost reduction without compromising coverage.
Time-limited policies seem cheaper, but they shift the risk onto you. If your dog develops a chronic condition, you'll pay for treatment out of pocket after 12 months. Ongoing arthritis treatment might cost £1,500-£2,000 a year. Diabetes management can run £1,000+ annually.
Suddenly that £50 annual saving looks very different against thousands in vet bills.
Both lifetime and time-limited policies exclude certain treatments, and these exclusions are pretty standard across the industry. Knowing what's not covered helps you avoid surprises when you claim.
These are excluded by virtually every pet insurer, regardless of policy type:
These are things you budget for separately as part of normal dog ownership.
Dental treatment is where policies differ significantly. Routine cleaning isn't covered by anyone. But treatment for dental disease, extractions, or accident-related damage might be covered depending on your policy level.
Basic policies often exclude dental altogether. Mid-tier policies might cover illness-related dental work. Top-tier policies usually include more comprehensive dental cover. For a detailed breakdown of what different insurers include, see our guide to pet insurance with dental cover.
Check your policy documents carefully if dental cover matters to you. The Insurance Product Information Document (IPID) should spell it out clearly.
Most policies don't cover behavioural problems like anxiety, aggression, or destructive behaviour. Some top-tier plans include it if a vet refers your dog to a certified behaviourist, but it's rarely included in standard cover.
If your dog has behavioural issues, you'll likely be paying for training or behaviour therapy yourself.
Hydrotherapy, acupuncture, physiotherapy, and other alternative treatments are sometimes covered, but often with limits. You might get a set number of sessions per year (like six hydrotherapy sessions), or a capped amount (like £500 for complementary therapy).
If your dog needs regular physiotherapy for arthritis, check what limits apply before assuming it's fully covered.
Dogs used for business purposes—racing, breeding, security work, or anything commercial—are often excluded. Banned breeds under the Dangerous Dogs Act are also typically excluded, though some specialist insurers will cover them with restrictions.
If you have a working dog or a breed that's sometimes restricted, check with the insurer before buying a policy.
For most dog owners, lifetime cover is worth the extra cost. The protection it offers against chronic conditions outweighs the higher monthly premium. Time-limited policies save money upfront but leave you exposed to potentially thousands in vet bills if something goes wrong.
Choose lifetime cover if:
Lifetime cover is particularly important for breeds with known health risks. Labradors and hip dysplasia, Cavalier King Charles Spaniels and heart disease, French Bulldogs and breathing problems—these are expensive conditions that need ongoing management.
Time-limited cover might be acceptable if:
Even then, it's a risk. You're betting that nothing chronic develops during the coverage period.
Before committing to any policy, get clear answers to these questions:
Always read the Insurance Product Information Document (IPID) and the full Terms and Conditions before buying. The IPID summarises the key features, exclusions, and limits in plain language. The full T&Cs contain all the detail about how claims work, what's excluded, and how coverage changes over time.
It's boring reading, but it could save you thousands in rejected claims.
Time-limited policies are cheaper, but they don't protect you where it matters most. Chronic conditions are common in dogs, and once your coverage runs out, you're on your own. Lifetime cover costs more each month, but it means ongoing conditions stay covered for your dog's entire life.
For most dog owners, the extra £30-£50 a year for lifetime cover is money well spent. It's the difference between being covered for a condition that might cost thousands over your dog's lifetime and having to pay for everything yourself after 12 months.
Get lifetime cover when your dog is young and healthy, keep renewing it, and you won't have to worry about losing coverage when something goes wrong.
Time-limited policies cover each condition for up to 12 months (or until a monetary limit is reached), after which that condition is permanently excluded. Lifetime policies reset the vet fee limit every year when you renew, continuing to cover all conditions—including chronic ones like arthritis or diabetes—throughout your dog's life as long as you maintain the policy.
Lifetime cover typically offers better long-term protection, especially for chronic conditions that need ongoing treatment. While time-limited policies are cheaper upfront, they leave you financially responsible for any condition after the 12-month coverage period ends. For most dog owners—particularly those who couldn't afford thousands in annual vet bills—the extra £30–£50 yearly for lifetime cover is worthwhile. However, the "best" option depends on your budget and willingness to self-fund treatment if needed.
Most time-limited policies cover each condition for 12 months from when it first shows symptoms or from the first vet visit—definitions vary by insurer. Some policies also impose a monetary limit (for example, £1,000 or £2,000 per condition). Once you reach the 12-month mark or the monetary cap, whichever comes first, that specific condition is excluded from all future coverage. Different insurers calculate start dates differently, so check your policy documents carefully.
For many dog owners, yes—especially if your dog develops a chronic condition that needs ongoing treatment. Conditions like arthritis, diabetes, allergies, and heart problems often require £1,000–£2,000+ in annual vet care. Lifetime cover keeps these costs insured year after year. Dogs from breeds prone to hereditary issues (hip dysplasia, heart disease, breathing problems) benefit particularly from lifetime cover. The extra monthly premium is typically offset by avoiding large out-of-pocket vet bills over your dog's lifetime.
You can switch insurers, but new policies will not cover conditions your dog already has. Pre-existing conditions—any illness or injury with symptoms before the new policy starts or during the waiting period—are universally excluded across the UK pet insurance industry. This means if your dog develops a chronic condition under a time-limited policy and you try to switch to another insurer, that condition will remain uninsured. You'll either need to stay with your current insurer or pay for that condition's treatment out of pocket going forward.
Nearly all policies exclude routine care, pre-existing conditions, and breeding-related costs. Standard exclusions include vaccinations, neutering, microchipping, flea/worm treatments, grooming, nail clipping, pregnancy, and administrative fees. Dental cover varies widely—basic policies often exclude it entirely, while premium policies may cover illness-related dental work. Behavioural treatment is rarely covered unless a vet refers your dog to a certified behaviourist. Complementary therapies like hydrotherapy or physiotherapy are sometimes included but usually with annual session or monetary limits.
