Assistance dogs: the legal position
Licensed taxi and private hire drivers in the UK have a legal duty to carry assistance dogs, and to do so at no extra charge. This sits under equality legislation rather than transport rules, and refusing is discrimination. There is no requirement for the dog to wear a jacket, carry documentation or be from a particular organisation, though many owners find those things reduce arguments in practice.
There is one narrow exception. A driver with a medical condition, most commonly a severe allergy, can apply to their licensing authority for an exemption certificate. If granted, they must display it in the vehicle. That is the only lawful basis for refusal, and it must be evidenced by the certificate, not asserted verbally.
If you are refused, the practical response is to note the vehicle licence number, the time and the location, and report it to the licensing authority and to the operator. In London that is Transport for London. Complaints of this kind are taken seriously because a driver's licence depends on it.
When you book, you do not need to ask permission for an assistance dog. Telling the operator is still worth doing, because it lets them allocate a vehicle with suitable footwell space and brief the driver, which makes the pickup smoother for everyone.
Pets in taxis and private hire vehicles
Ordinary pets are different. There is no legal right to bring a pet into a licensed vehicle, and a driver may decline. In practice most operators will carry pets if you arrange it in advance and the animal is appropriately contained, but turning up unannounced at 5am with a cat in your arms is how a booking gets refused.
What operators generally want is straightforward. The animal in a secure carrier or crate for anything cat-sized or smaller. Larger dogs restrained properly, since an unrestrained animal in a moving vehicle is both a safety risk and a Highway Code issue. A blanket or cover for the seat or boot. And honesty about size, because a vehicle allocated for a spaniel will not work for a great dane.
Expect a cleaning or handling supplement with some operators. Ask about it when booking rather than discovering it afterwards.
Bringing a pet into the UK: start months ahead
This is the part that catches people relocating, and it cannot be rushed. The UK operates a pet travel scheme with requirements that typically include microchipping, rabies vaccination with a waiting period before travel, and health documentation issued within defined timescales. Dogs entering from most countries also require treatment against a specific tapeworm within a set window before arrival. The exact requirements depend on which country you are travelling from and the current rules.
Two structural points matter more than the detail. First, pets generally cannot arrive in the UK as cabin baggage. With the exception of assistance dogs, animals normally have to travel as manifested cargo on an approved route with an approved carrier, which is a separate booking from your own ticket and is often the most expensive part of a relocation. Second, arriving with paperwork that is even slightly out of date can mean the animal is placed into quarantine at your expense, so the timescales are not advisory.
Check the official UK government pet travel guidance and speak to a vet experienced in export documentation. Start at least four months before you fly.
Animals arriving as cargo are usually collected from an animal reception centre rather than from the passenger terminal. At Heathrow this is a separate facility with its own address and opening hours, so factor it into your arrival day and tell your driver, because it is not where they would otherwise take you.
Making the transfer work on the day
Tell the operator everything when you book: species, size, carrier dimensions, whether the animal is an assistance dog, and whether you are collecting from an animal reception centre rather than arrivals. Ask for a vehicle with genuine boot space, because a carrier plus three suitcases does not fit in a saloon. Keep water and a lead accessible rather than packed. Do not open a carrier in the car, however distressed the animal sounds. And if the journey is long, tell the driver in advance if you may need to stop.
