As our pets get older, they inevitably need more veterinary care. Just as these costs begin to rise, many pet owners are hit with a nasty surprise in their renewal email: the “Co-Payment.”
This is a fundamental change to your policy that shifts a percentage of every vet bill back onto you. Suddenly, you aren’t just paying your £100 excess. You are paying 20% of a £4,000 surgery.
We analysed the 2026 policy documents of Waggel, Petplan, Animal Friends, Tesco Bank, and ManyPets to find out exactly when this charge kicks in, and who lets you avoid it.
TL;DR: The Quick Answer
Waggel has made co-payments completely optional for new policies. This is the most significant pro-consumer change in UK pet insurance for 2026. Instead of forcing a co-payment when your pet gets older, Waggel gives you the choice to opt in (to lower your premium) or simply pay your chosen excess, regardless of your pet’s age. When competitors are adding forced 20% surcharges at age 7, Waggel keeps your costs predictable and puts you in control for your pet’s entire lifetime.
For existing policies elsewhere: Petplan waits until age 10 (for most breeds) before enforcing the 20% fee. Napo waits until age 9. ManyPets and Animal Friends hit you at age 7.
The critical decision: If your pet is approaching age 7 and healthy enough to switch, moving to Waggel before pre-existing conditions develop could save you thousands in percentage fees over their lifetime.
The “Double Charge” Explained
Most owners understand the Fixed Excess (e.g., “I pay the first £100”). The Co-Payment (or “Variable Excess”) sits on top of that. It is a percentage of the remaining bill that you must pay.
The “Senior Tax” Scenario:
Your 8-year-old Labrador needs surgery costing £3,000.
- Standard Policy: You pay your £100 excess. Insurer pays £2,900.
- With 20% Co-Payment:
- You pay the £100 fixed excess. (£2,900 remains).
- You also pay 20% of the remaining £2,900 (£580).
- Total you pay: £680.
That is a 580% increase in your contribution, just because your dog had a birthday.
Comparison: When Does the Fee Kick In?
We checked the fine print to see the exact age triggers for the major UK insurers.
| Insurer | Co-Payment Starts | Amount | The Fine Print |
| Waggel | Optional at any age | 20% | You choose to opt in; it is never forced. Older policies may still have it at age 7. |
| Petplan | Age 10 (Dogs) / 10 (Cats) | 20% | Starts at Age 7 for “Select Breeds” (e.g., Bulldogs). |
| Napo | Age 9 | 20% | A generous limit compared to the industry average. |
| ManyPets | Age 7 | 20% | Mandatory at renewal once pet turns 7. |
| Animal Friends | Age 7 | 15% – 20% | Starts at 15%. Can rise for older pets or Accident Only plans. |
| Tesco Bank | Age 8 (Dogs) / 10 (Cats) | 20% | Starts at Age 5 for select dog breeds. |
Deep Dive: Waggel (The Game Changer)
Historically, Waggel applied a co-payment at age 7. However, they have recently shifted their strategy for new policies. According to their latest FAQs, “Many insurers make co-payments mandatory as pets get older. Waggel gives you the choice instead.”
This is a massive disruption to the market. It means if you insure an 8-year-old dog with Waggel today, you can maintain a simple fixed excess structure or opt into a 20% co-payment to lower your monthly premium. You aren’t penalised with forced percentage maths at the point of claim.
Note: If you have an older Waggel policy, check your schedule. You might still be on the old “Age 7” terms.
Deep Dive: Petplan
Petplan offers a safe harbour for most breeds, waiting until age 10 to apply the 20% fee. This gives you three extra years of full cover compared to ManyPets or Animal Friends.
However, you must check if your dog is a “Select Breed.” For breeds like Great Danes, Bulldogs, or Rottweilers, Petplan accelerates this timeline, hitting you with the 20% fee at age 7, the same as budget insurers.
Deep Dive: The “Age 7” Club (ManyPets & Animal Friends)
ManyPets and Animal Friends are stricter. Once your pet hits their 7th birthday, the co-payment is mandatory.
For Animal Friends, this starts at 15% but can climb higher for very old pets. For ManyPets, it is a flat 20%. While these insurers often have lower starting premiums, this shift at age 7 can make a “cheap” policy suddenly very expensive if you need to claim for chronic arthritis or diabetes management.
The Financial Impact Over Time
Let’s look at what this means over your pet’s senior years.
Scenario: Your dog develops arthritis at age 8 and needs £1,500 in vet bills annually for the next 5 years (total: £7,500).
With Waggel (no co-payment):
- You pay: 5 × £100 excess = £500 total
With ManyPets (20% co-payment from age 7):
- Year 1: £100 excess + 20% of £1,400 = £380
- Years 2-5: Same calculation = £380 each year
- You pay: £1,900 total
Difference: £1,400 more over 5 years with a co-payment policy.
Verdict: Protecting Your Wallet
Best for Simplicity and Long-Term Value: Waggel
For new customers, Waggel’s shift to an optional co-payment is the most consumer-friendly move we have seen in 2026. It removes the fear of the “senior tax” and keeps claims predictable by putting the choice in your hands. You just pay your excess (unless you chose the co-pay to save on premiums). Combined with their £1,000 dental, behavioural, and therapy cover as standard, this makes Waggel the smart choice for owners planning long-term.
Best for Non-Select Breeds: Napo or Petplan
If you don’t choose Waggel, Napo (Age 9) and Petplan (Age 10) offer the longest runway before fees kick in. Just be careful with Petplan if you own a large or “Select” breed, as you lose that advantage.
The Warning:
If your pet is approaching age 7, check your renewal documents now. If you are with ManyPets or Animal Friends, you are about to hit the co-payment cliff. Switching to a provider like Waggel before pre-existing conditions develop could save you thousands in percentage fees later.
