Most pet travel is non-commercial: you move your own dog, cat or ferret for personal reasons. Different rules apply when a pet is being sold, rehomed or handed to a new owner. And under the 5-day rule a pet can travel on a different day from its owner. This guide explains the difference in plain words, based on GOV.UK guidance (last checked 5 November 2026).

The Short Answer

  • Non-commercial: your own pet, travelling for personal reasons, with you or with someone you authorise.
  • Commercial: a pet that is being sold, rehomed or transferred to a new owner, or more than 5 pets travelling for something other than a competition, show or sporting event.
  • The 5-day rule: your pet can travel with someone else, before or after you, as long as it is within 5 days of your own journey to the same destination and you have given permission in writing.

What Counts as Non-Commercial Pet Travel

A non-commercial journey is an ordinary personal trip: a holiday, a move, a visit to family. The pet is yours, the owner is named on the pet travel document, and the pet is not going to be sold or rehomed.

  • The declaration: when your vet issues the Animal Health Certificate for leaving Great Britain, you also get a declaration to sign. It confirms that you will not sell or re-home the pet while you are abroad.
  • Coming back to Great Britain: you fill in a declaration if you are not going to sell or transfer ownership of the pet.
  • How many pets: you can take up to 5 pets in a private vehicle to an EU country, or up to 5 as a foot passenger. More than 5 is only allowed for an event (a competition, show or sporting event) or when exporting for commercial purposes.

The documents do not change: microchip, rabies vaccination, the right pet travel document and, for dogs entering Great Britain, tapeworm treatment. See our Animal Health Certificate guide and pet passport guide for the details.

What Counts as Commercial

GOV.UK treats a move as commercial, or as needing extra rules, in these cases:

  • the pet is going to be sold, rehomed or have its ownership transferred;
  • you are bringing more than 5 pets and are not attending or training for a competition, show or sporting event;
  • when entering Great Britain, the pet arrives more than 5 days before or after you.

For Great Britain these cases fall under extra rules known as Balai rules, on top of the microchip, rabies and tapeworm requirements. If you are exporting a dog, cat or ferret for commercial purposes, such as a change of ownership, check the rules of the country you are exporting to. Our guide to importing a pet to the UK from the EU covers the UK side.

A pet going to a buyer, to an adopter or to a new home through a rescue is a sale, a rehoming or a transfer of ownership, so it falls under the cases above. Plan those moves with the official rules for the country concerned.

The 5-Day Rule Explained

The 5-day rule is how GOV.UK describes a pet travelling with someone other than its owner, for example a friend or a family member. The journey must be:

  • Within 5 days of your journey, either before or after it;
  • To the same destination as your own journey;
  • With your permission, given in writing.

How the permission works

You give permission by signing a declaration that names the person who will travel with your pet. Only the owner named on the pet travel document can give it. The person travelling with the pet must carry two things: the signed declaration, and proof that you are travelling within 5 days of the pet.

When your dates are further apart

If you are not travelling within 5 days of your pet, GOV.UK points to the Animal and Plant Health Agency (APHA) Pet Travel helpline for advice. When entering Great Britain, a pet that arrives more than 5 days before or after you is covered by the extra Balai rules mentioned above, so it is worth fitting your dates inside the window.

Not the same as the tapeworm window

Dogs entering Great Britain also need tapeworm treatment between 24 hours and 5 days before arrival. That is a separate 5-day period, and it does not move the 5-day rule for the pet's journey.

When a Pet Travels Apart From Its Owner

Under the 5-day rule there are a few common situations where an owner and a pet do not travel on the same day:

  • You fly on a Friday and your pet goes by road earlier in the week or the Monday after, to the same destination.
  • You are moving house and the removal dates do not match your own travel dates.
  • A family member drives to the same destination and takes the pet with them.

In all of these the move stays non-commercial: the pet is yours, it is not being sold, adopted or rehomed, and you or an authorised person reach the same destination within the 5 days. The documents are the same as for any other journey.

Checking the Transport Company: DEFRA Authorisation

If a transport company drives your pet while you travel separately, the journey can be a long one, and the company needs the right authorisation. GOV.UK (Transporting animals in Great Britain) says that you must have a UK-issued transporter authorisation to transport animals over 65 km by air, road, rail or sea:

  • Type 1 for journeys over 65 km and up to 8 hours;
  • Type 2 for journeys over 8 hours.

The transporter must carry a copy of the authorisation and show it on request, so ask to see it before you book. For longer journeys GOV.UK also lists a certificate of vehicle approval, and many UK to Europe pet journeys run longer than 8 hours door to door. Ask the company which authorisation it holds and keep a copy with your pet's documents.

How a Pet Taxi Fits In

At PetVoyageUK you normally travel with your pet in the same vehicle, door to door. When you, or someone you authorise, travel to the same destination within 5 days before or after your pet, your pet can also go by road on its own days, always as a non-commercial move. We do not move pets for sale, adoption or rehoming. When you ask for a quote, tell us both sets of dates and we will check that they fit the rule.

Quick Checklist

  • The pet is yours and is not being sold, adopted or rehomed.
  • No more than 5 pets, unless you are attending or training for an event.
  • Microchip, rabies vaccination and the right pet travel document are in order, plus tapeworm treatment for dogs entering Great Britain.
  • If the pet travels apart from you: your journey and the pet's are to the same destination and within 5 days of each other.
  • You have signed a declaration naming the person who travels with the pet, and that person carries it with proof of your own travel.
  • You have checked the transport company's authorisation (type 1 or type 2) and seen a copy.

Frequently Asked Questions

Can my pet travel without me?

Yes, in some cases. Under the 5-day rule your pet can travel with someone you authorise if the journey is to the same destination as yours, within 5 days before or after it, and you have given permission in writing. The move must be non-commercial.

Can a friend or family member take my pet abroad?

Yes. They need the signed declaration that names them and proof that you are travelling within 5 days of the pet. Only the owner named on the pet travel document can give that permission.

How many pets can I take?

Up to 5 pets in a private vehicle to an EU country, or up to 5 as a foot passenger. More than 5 is only allowed if you are attending or training for an event, or exporting for commercial purposes.

What if my journey is more than 5 days apart from my pet's?

For travel out of Great Britain, GOV.UK points you to the APHA Pet Travel helpline. For a pet entering Great Britain, arriving more than 5 days before or after you brings the extra Balai rules into play. Fit your dates inside the window if you can.

Can I send my pet to a new owner or a rescue?

That is not a personal trip. Selling, rehoming or transferring ownership are on the list of cases that need extra rules, so check the rules for the country involved before you plan the move.

Does the 5-day rule change the vet paperwork?

No. Microchip, rabies vaccination, the pet travel document and, for dogs entering Great Britain, tapeworm treatment still apply. The 5-day rule only decides whether the journey counts as the same non-commercial trip as yours.

Which official pages should I read?

Taking your pet dog, cat or ferret abroad, Bringing your pet dog, cat or ferret to Great Britain and Transporting animals in Great Britain. Rules change, so check them close to your travel date.
