What is third party liability pet insurance?

Third party liability pet insurance covers you if your pet causes injury to someone else or damages their property, and you’re held legally responsible for the costs.

For example, if your dog runs into a cyclist and injures them, or damages someone’s belongings, third party cover could help pay for compensation and legal costs, depending on the policy.

It’s different from vet fee cover, which helps pay for treating your own pet.

Third party liability cover is particularly important for dog owners because, under the Dogs Act 1971, owners can be held responsible for damage or injury caused by their dogs in certain circumstances.

Some pet insurance policies include third party liability cover as standard, while others offer it as an optional extra. Check the policy limits and exclusions carefully, as the amount of cover can vary.

What is covered by third party liability pet insurance?

Third party liability pet cover can help pay for:

• legal expenses

• compensation claims

• vet bills for injured animals

• medical costs if someone is hurt

• property damage

It can also cover wider compensation, such as loss of earnings if someone is unable to work following an injury caused by your dog.

What situations would third party liability cover me for?

Third party liability cover can help if your pet causes injury to someone else or damages their property, and you’re legally responsible for the costs. Situations could include:

• Your dog bites or injures someone, such as another dog walker or visitor

• Your dog knocks someone over, causing an injury that leads to a compensation claim

• Your dog runs into a cyclist or motorist, causing an accident or injury

• Your dog damages someone’s property, such as knocking over an expensive item in their home

• Your dog escapes and causes an accident, for example by running into a road

💡Top tip: If an incident occurs, do not admit responsibility and do not offer or agree to pay any money to any person without first speaking to your insurer. Third party liability claims can be invalidated if you do this.

Do I need third party liability insurance for my dog?

You don’t usually need third-party liability insurance for your dog by law in the UK.

However, if you are renting a home, your landlord, local authority or housing association may require you to have third-party liability cover as part of your tenancy agreement. Check your contract to see whether this applies to you.

Do I need third party liability insurance for my cat?

Pet insurers do not usually offer third party liability cover for cats.

This is partly because cats are generally considered less likely to cause the kind of injury or damage that leads to liability claims, and partly because cats are treated differently to dogs under law.

Cats have a legal 'right to roam' which means their owners are not required to control them outdoors or prevent them from entering private property.

Is third party liability cover standard in all pet insurance policies?

No. Third-party liability cover isn’t standard on all pet insurance policies. It’s more commonly included with dog insurance, but the level of cover and whether it’s included at all can vary between policies.

Before buying, check whether the policy includes:

• Third-party liability as standard or as an optional extra

• How much liability cover you get

• Whether there are any exclusions

• Whether legal costs are included

• Whether the cover applies to incidents involving your pet both at home and away

If third-party cover is important to you, don’t assume it’s included just because you have pet insurance. Check the policy wording before you buy.

Does pet insurance cover my dog attacking another dog or livestock?

Third party liability insurance may cover some of the costs if your dog injures another animal or livestock and you are found legally responsible. For example, it could cover any compensation that is paid to the other owner or farmer and the associated legal costs.

However, insurers usually expect owners to have taken all reasonable precautions to stop the attack from happening. That means it may not pay out if your dog was off-lead or if it had a previous history of aggression.

Does third party liability insurance pet insurance cover fines or legal penalties?

No. Third party liability cover won’t pay fines, fixed penalty notices or criminal penalties. These costs are your responsibility.

For example, dog owners can face an unlimited fine if their dog is dangerously out of control. There are also penalties for offences such as allowing a dog to foul in public.

Fines can also be substantial if your dog worries livestock. The law allows unlimited fines for owners whose dogs attack, chase or worry farm animals.

So, when walking through farmland, always keep your dog under control and follow any local signs about keeping dogs on leads.

Does third party liability insurance pet insurance cover dogs in the workplace?

Some policies may cover your dog if they are simply accompanying you at your workplace.

If you take your dog to work, check your policy for:

• Whether your dog is covered at your workplace

• Any exclusions for business or commercial use

• Whether cover applies to incidents involving colleagues, customers or visitors

• Any conditions you need to meet

Don’t assume your dog is covered just because they have third-party liability insurance. If taking your dog to work is important, ask the insurer to confirm the cover in writing.

Third party liability pet insurance will generally cover incidents that happen in other people's workplaces, for example if you take your dog into a cafe or pub where you are a customer.

However business use is usually excluded. Working dogs, such as those used for security or therapy purposes, are generally not covered at all by standard pet insurance. You will need specialist cover.

Does third party liability cover apply if my dog injures me or members of my household?

Usually, no. Third-party liability cover generally protects you if your dog injures someone outside your household, rather than you or people who live with you.

It almost always excludes:

• the pet's owner

• anyone who lives in the pet's household, including tenants or roommates in shared accommodation

• anyone who is visiting the pet's household

• immediate members of the pet owner's family

• dog-sitters (including unpaid dog sitting by friends and family)

• business contacts of the pet owner, including employees

💡Top tip: Most home insurance policies won't cover pet damage either. So if your dog rips up your sofa or pees on your carpet, you're almost certainly going to have to swallow the cost yourself.

How much third party liability cover do I need?

Pet insurance policies often include third party liability cover of around £1 million to £2 million, although the exact limit varies by insurer.

These cover limits are so high because claims can involve serious injury, legal action or significant property damage. Compensation and legal costs can quickly run into tens or even hundreds of thousands of pounds, so higher limits help protect you against these risks.

How much does third party pet insurance cost?

The average cost of pet insurance for dogs is £12.33^[1] per month, but this will vary depending on specific factors about your pet and policy such as the breed, age, type of policy, health history and past claims.

What will third-party liability cover for dogs not cover?

Third party liability cover for dogs will generally not cover:

• Dogs with known aggressive behaviour

• Banned dog breeds

• Incidents that happen while your dog is being used for business purposes

• Injury or damage to you, your family, members of your household, guests, employees, or anyone handling your dog with your permission

• Damage to property owned by you or people connected to you, such as your home or belongings

• Fines, compensation or prosecution costs following criminal proceedings, although it may cover the legal costs of defending those proceedings

• Incidents that result from a deliberate act by you, or from something you could reasonably have prevented.

Does third party liability pet cover dangerous dogs?

No, standard third party liability pet insurance (and pet insurance generally) will generally not cover dogs classed as dangerous or banned in the UK.

These banned breeds include:

• Pit Bull Terrier

• Japanese Tosa

• Dogo Argentin

• Fila Brasileiro

• American XL Bully

A Certificate of Exemption lets you keep a banned dog as long as it does not behave dangerously, and you follow certain rules. It is valid for the life of the dog.

Your dogs must be:

• neutered

• fitted with a microchip

• kept on a lead and muzzled at all times when in public

• kept in a secure place so it cannot escape

As the owner, you must:

• be aged over 16

• show the Certificate of Exemption when asked by a police officer or council dog warden, either at the time or within 5 days

• let the Index of Exempted Dogs know if you change address, or your dog dies

Up until 30 June 2026 you needed third party liability insurance for banned dogs, but you don’t anymore. The government changed the rules as insurance companies were not willing to offer third party cover for banned breeds.

However, it is important to note that even though the insurance mandate is gone, owners remain entirely responsible for any damage or injury caused by their dogs.

Can I buy standalone liability insurance for my dog?

Yes, although standalone third-party liability insurance for dogs can be hard to find. In most cases, third-party liability cover is included as part of a wider pet insurance policy.

Standalone cover is designed to help if your dog injures someone or damages their property and you’re legally responsible. It can cover costs such as compensation claims and legal fees, subject to the policy terms and limits.

It may suit you if you don’t want full pet insurance but still want protection against liability claims. Before buying, check the level of cover, the liability limit and any exclusions, including restrictions on certain breeds or types of dog.

The Insurance Emporium is one provider that offers standalone third-party liability cover for dogs.

You may also already have some liability protection through your pet insurance, home insurance or membership of a dog owners’ organisation, so check what cover you have before buying a separate policy.
