Most passengers give licensing no thought at all until something goes wrong, and by then the question has become an expensive one. Yet the system that governs every pre-booked car in the capital is neither secret nor complicated. Transport for London licenses private hire in three separate parts, and understanding what each of them covers tells you a great deal about the company you are dealing with before you ever step into a vehicle. It also explains a number of things that puzzle people: why a chauffeur cannot pick you up if you wave at the car, why you are asked for details in advance that a black cab would never request, and why the price can be fixed before you travel. This guide sets out how the three licences work, what each one demands, how long they last, and how you can check any of them yourself in a couple of minutes. It is written for passengers rather than for the trade, so there is no jargon that is not explained on the spot.
Three licences, not one
The single most useful thing to know is that there is no such thing as one private hire licence. Transport for London issues three, and all three must be valid at the same time for a journey to be legal. The operator is licensed to accept the booking and keep a record of it. The driver is licensed as an individual, after checks on their background, their health and their command of English. The vehicle is licensed in its own right, inspected and insured for carrying passengers for hire and reward. Take away any one of the three and the journey is not a licensed private hire journey, whatever the website says. This matters because a company can look entirely convincing while missing one leg of the stool. A smart car and a courteous driver tell you nothing about whether the paperwork behind them exists. The three licences do, and each one is checkable.
The operator licence
The operator is the business that takes your booking, and it carries the legal responsibility for it. To hold a licence, an operator must have suitable premises, keep records of every booking and every driver and vehicle used, hold the right insurance, and satisfy Transport for London that the people running it are fit and proper to do so. Records are not a formality: an operator must be able to show who accepted a booking, which driver was assigned, and which vehicle went. That audit trail is precisely why a pre-booked journey can be traced afterwards and a street hail cannot. Operator licences run for a set term rather than indefinitely, and are renewed only after the operator satisfies the same tests again. Every licensed operator has a number. Ours is 73850301, and you will find it published on this site rather than buried, because a number nobody can find is not much of a reassurance. Any operator that will not give you theirs is telling you something.
The driver licence
A private hire driver licence is personal to the individual, and it is considerably harder to obtain than a standard driving licence. An applicant must hold a full driving licence, have held it for at least three years, and prove the right to work in the United Kingdom. Beyond that, the requirements are the ones that matter to a passenger.
There is an enhanced check through the Disclosure and Barring Service, which reveals far more than a basic criminal record check and is the same standard used for people working with children and vulnerable adults. Drivers are required to remain enrolled with the update service so their status can be rechecked periodically rather than once at the start of a career. There is a medical examination to professional driving standards, the same category applied to lorry and bus drivers, which is repeated as a driver gets older. There is an English language requirement, introduced so that a driver can read a safety notice, understand a passenger and communicate in an emergency. Each of these is a hurdle, and each removes a proportion of applicants.
The vehicle licence
The car itself is licensed separately, and it must pass an inspection to be granted that licence. The vehicle must meet age and condition requirements, carry insurance for hire and reward rather than ordinary private cover, and display its licence discs. Inspections are more frequent than a standard annual test, because a car doing high mileage with passengers aboard wears differently from a family runabout. Emissions rules also apply, and they have tightened considerably: newly licensed private hire vehicles in London have been required to be zero emission capable since January 2023, which is steadily changing what the trade drives. If you are curious about where that leads, we have written separately about the shift towards electric chauffeur travel and what it means for passengers. The practical point for now is simple: a licensed vehicle has been examined by someone whose job is to fail unsafe cars.
Private hire and black cabs are different trades
London runs two licensed trades side by side, and they are not variations of the same thing. A hackney carriage, the black cab, may be hailed in the street or picked up at a rank, and its drivers complete the Knowledge, the celebrated examination in London's streets and routes. A private hire vehicle may not be hailed at all. It must be booked in advance through a licensed operator, and that single rule shapes everything else about how it works. Because the journey is arranged beforehand, the operator knows the route, which is why the fare can be agreed in advance instead of accruing on a meter. Because a specific driver is assigned to a specific job, that driver can be briefed, and the vehicle can be matched to the number of passengers and cases. Neither trade is superior; they solve different problems. A black cab is unbeatable when you need a car this minute. Pre-booking wins when you need certainty about the price, the vehicle and the person driving it.
Why you cannot flag down a chauffeur car
This surprises people, and occasionally offends them, so it is worth being plain. If you stop a private hire car in the street and ask for a lift, the driver is required to decline. Accepting would breach the terms of their licence and the operator's, and it would invalidate the insurance that covers you as a passenger. It is not standoffishness and it is not a sales tactic. A chauffeur waiting outside a hotel is there for the person who booked them, and cannot take you instead however empty the car looks. The same rule explains why we ask for details before a journey rather than at the kerb. Those details are the booking record, and the booking record is what makes the journey lawful. Our own London chauffeur service is built entirely around pre-booked work for that reason.
What licensing actually buys a passenger
Strip away the administration and the three licences deliver four things that matter when you are in the back of a car late at night. You know who the driver is, because they have been identified, background checked and licensed as an individual. You know the car has been examined and insured for the job it is doing. You know there is a record of your journey held by a licensed business, so the trip is traceable if anything goes wrong. And you know there is a regulator to complain to, which is a meaningful difference from an informal arrangement where your only recourse is the goodwill of the person who took your money. None of this guarantees a pleasant journey. It does establish a floor below which a licensed operator cannot fall without consequences, and that floor is the whole point of the system.
What happens when a licence is suspended
Licences are not only granted, they are removed, and the possibility of removal is what gives the system its teeth. Transport for London can suspend or revoke a driver's licence, an operator's licence or a vehicle licence, immediately where public safety requires it. Convictions, complaints, failing to maintain a vehicle, poor record keeping and dishonesty in an application can all trigger action. A driver whose licence is revoked cannot simply keep working, and an operator that loses its licence cannot lawfully take a booking. For a company with staff, vehicles and a reputation, that is an existential risk, and it is the reason a serious operator treats the paperwork as seriously as the driving. From a passenger's point of view this is the part that turns a set of rules into a real deterrent. Standards that carry no penalty are advice. Standards that can end a business overnight are enforcement, and the difference shows in how carefully a licensed operator behaves when nobody is watching.
Licensing and the corporate traveller
Companies booking travel for their people have a further reason to care, because duty of care does not stop at the office door. An employer sending a colleague across London late at night is expected to have taken reasonable steps over how that person travels, and "we used an app" is a thinner answer than a named licensed operator with records of every journey. This is why procurement teams increasingly ask for a licence number, insurance details and a policy on driver checks before opening an account, and why we publish ours rather than waiting to be asked. If you are setting up travel for a team, our corporate chauffeur accounts exist partly to make that documentation straightforward, with consolidated billing and a record of who travelled where. The licensing framework is doing useful work here beyond passenger safety: it gives an employer something concrete to point at.
How to check a licence yourself
You do not have to take anyone's word for any of this, and checking takes very little time. Every licensed private hire vehicle displays licence discs, usually in the front and rear windows, showing the licence number and expiry. Every licensed driver carries a badge with their photograph and licence number, and is required to produce it on request. Transport for London publishes an online checker where a licence number can be verified directly. If you want to be thorough before travelling rather than at the kerb, ask the operator for their licence number when you book and check it then, calmly, rather than trying to inspect a windscreen in the dark with your luggage in your hand. A legitimate operator will not mind being asked. In our experience the request is rare, which is a shame, because it is the single most effective thing a passenger can do.
Warning signs worth taking seriously
A few things should give you pause. A quote that is dramatically below everyone else's is usually a signal that a corner is being cut somewhere, and licensing is one of the more expensive corners. An operator who will not give a licence number, or who becomes evasive when asked, has answered the question. A vehicle with no licence discs is not licensed, whatever the driver says about them being renewed. A driver who cannot produce a badge is not a licensed driver. And an unsolicited approach in an airport arrivals hall or outside a station, offering a car there and then, is by definition not a pre-booked private hire journey, whatever the person is holding. Illegal plying for hire is the trade's persistent problem, and it exists because passengers in a hurry rarely stop to think. The safest habit is simply to book in advance, from a company whose number you have seen.
What is a private hire vehicle licence?
It is the permission that allows a vehicle to carry passengers on pre-booked journeys. It is granted only after the car passes inspection and is insured for hire and reward, and it is displayed on discs in the vehicle's windows. It is separate from the driver's own licence and from the operator's, and all three must be valid for the journey to be legal.
Is a private hire vehicle the same as a black cab?
No, they are separate licensed trades. A black cab is a hackney carriage and may be hailed in the street or taken from a rank. A private hire vehicle may only be booked in advance through a licensed operator and cannot legally accept a street hail. The difference in how the journey is arranged is why one uses a meter and the other can quote a fixed price.
What checks does a private hire driver go through?
An enhanced Disclosure and Barring Service check, a medical to professional driving standards, and an English language requirement. Applicants must also hold a full driving licence, have held it for at least three years, and prove their right to work in the United Kingdom. The licence is renewed periodically rather than granted for life, so the checks recur.
How long does a licence last?
Each of the three runs for a fixed term and must be renewed. Vehicle licences are the shortest and involve regular inspection, driver licences run for a period of years subject to continuing checks, and operator licences run longer again. None of them is permanent, which is the point: a licence granted once and never revisited would be worth very little.
Can I check whether a company is licensed?
Yes, and it takes a couple of minutes. Ask the operator for their licence number, then verify it with Transport for London's online checker. You can also inspect the licence discs displayed in the vehicle and ask the driver to show their badge. Any operator unwilling to give you a number is worth avoiding on that basis alone.
Does licensing mean the price is fixed?
Not automatically, but it is what makes a fixed price possible. Because a private hire journey is booked in advance, the route is known before the car moves and can be priced up front. A hackney carriage hailed in the street cannot know where it is going, which is why it runs a meter instead. Fixed pricing is a consequence of pre-booking rather than of licensing itself.
What insurance covers me as a passenger?
Hire and reward insurance, which is a different product from ordinary private car cover. A licensed vehicle cannot be licensed without it, and ordinary personal insurance would not respond to a claim arising from paid passenger work. This is one of the practical reasons an unlicensed lift is a poor idea however friendly the offer.
What should I do if a driver approaches me at the airport?
Decline, and use a car you booked in advance. An unsolicited offer in an arrivals hall is not a pre-booked private hire journey, and accepting it means travelling with no booking record, no assigned driver and no certainty about insurance. If you have booked with an operator, your chauffeur will be waiting inside with a board bearing your name.
Do these rules apply outside London?
The structure is similar, but the licensing authority is different. Outside the capital, private hire is licensed by local councils rather than by Transport for London, and the details of requirements vary between areas. The three-part principle of operator, driver and vehicle is common across England and Wales, so the checks a passenger can make are much the same wherever you travel.
Does a licensed chauffeur have to take an assistance dog?
Yes. Licensed drivers and operators have duties under equality law to carry assistance dogs, and refusing is a serious matter that can affect a licence. Guide dogs and other assistance dogs travel with their owner at no additional charge and no notice is required, although telling us in advance simply lets the driver prepare the vehicle sensibly.
