Its long and comples and the best thing to do would be to call DEFRA and ask about your specific case but basically.
There is a list of approved countries from which you can get a pet passport and as long as they are up to date on all shots (which you have to be to get the passport) they rarely quarantine unless your animal comes into contact with another animal which may have diseases en route - but they will still have to have a full check up on arrival.
For other countries, the animal will be quarantined for up to 6 months, particularly if they are not rabies free countries etc.
There are also limits on some carriers on how many animals you can bring with you so check that too if you have more than one animal. The Uk will allow no more than 5 animals to be brought in as well.

Basically to skip quarantine you need to (in this order!!!)
- Have your pet microchipped
Before any of the other procedures for pets are carried out, your pet must be fitted with a microchip so that it can be properly identified.
- Have your pet vaccinated
After the microchip has been fitted your pet must be vaccinated against rabies. There is no exemption to this requirement, even if your pet has a current rabies vaccination
- Arrange a blood test
After your pet has been vaccinated, it must be blood tested to make sure that the vaccine has given it a satisfactory level of protection against rabies.
- Get pets documentation
For animals being prepared in an EU country, you should get an EU pet passport. If you are preparing your animal in a non-EU listed country you will need to obtain an official third country veterinary certificate although note that Gibraltar and Switzerland are also issuing passports.
Animals can also enter the UK using a pets certificate issued before 1 October 2004 until its â€œvalid untilâ€ date. Certificates issued on or after that date will not be acceptable for entry to the UK.
- Before your pet enters the UK, it must be treated against ticks and a tapeworm
Your pet must be treated against ticks and a tapeworm between 24 - 48 hours before it is checked in with an approved transport company for its journey into the UK.
- Arrange for your animal to travel with an approved transport company on an authorised route
Your pet must enter the UK from a listed country travelling with an approved transport company on an authorised route.
