Ride-sharing, ride-hailing and private hire: what UK law calls them

Founders and journalists use "ride-sharing" and "ride-hailing" loosely. The Acts that license these services use neither word. If you're planning an app, you need the words the law uses, because they decide which licence you need. Here's the vocabulary, where each term is defined, and where ride sharing vs ride hailing lands in it.

Does UK law use the words ride-sharing and ride-hailing?

No. The Acts talk about taxis or hackney carriages, private hire vehicles, operators, public service vehicles, hire or reward, and separate fares. Every app-based service falls into one of those boxes.

Of all these, the private hire vehicle definition is the one most founders need. Fewer than nine passenger seats, a driver, and provided for hire: that's a ride-hailing car.

What's the difference between a taxi and a private hire vehicle?

A taxi can be hailed in the street or picked up at a rank. A private hire vehicle can't. The Supreme Court's summary of its 2025 Uber Britannia judgment says PHVs cannot ply for hire on the streets and are booked in advance through an operator.

Plying for hire turns on the vehicle being on show for hire to the public. Apps tested the line. In Reading Borough Council v Ali in 2019, the High Court held that a private hire driver parked up and waiting for bookings through the Uber app wasn't plying for hire. The app showed cars on a map, but it didn't let a passenger pick out that particular car; the booking still went through the operator.

So ride-hailing, in legal terms, is fast pre-booking. However quickly the car arrives, the booking goes through a licensed operator first. Our guide to hackney carriage vs private hire covers the taxi side.

Where does ride-hailing fit in the law?

Ride-hailing is private hire, and the company running the app is the operator. In Uber BV v Aslam in 2021, the Supreme Court rejected the argument that Uber was only a technology company and booking agent. It found that Uber London contracts with passengers and engages drivers to carry out the bookings.

The contract model now differs by place:

• London: in December 2021 the High Court declared that a licensed operator who accepts a booking must contract with the passenger as principal to provide the journey.
• Outside London: in July 2025 the Supreme Court held that the 1976 Act imposes no such requirement, so agency models remain lawful.
• Everywhere outside London: section 56(1) of the 1976 Act deems every contract for the hire of a licensed private hire vehicle to be made with the operator who accepted the booking, whether or not that operator provided the car.

Software doesn't change the category. Dispatch AI is booking and dispatch software for taxi and private hire firms, and the jobs a private hire firm books through it are private hire bookings under these Acts, with the same record-keeping duties. For the licence itself, see the operator licence for a ride-hailing app.

What does hire or reward mean?

Hire or reward means someone pays for the passengers to be carried. Section 1(5) of the 1981 Act spells out how wide that is: payment counts whoever it's made to, it still counts as a fare if it also pays for other things, and paying for a right to be carried counts even if the passenger never uses it.

That width matters for apps. For the 1981 Act's purposes, a booking fee paid to the platform, a subscription that includes rides, or a fare paid to the driver all count. Insurers draw the same line: the Association of British Insurers says that if you carry passengers who are charged a fare, you need hire and reward insurance.

When are shared rides at separate fares legal?

In a licensed car, when every passenger booked in advance and agreed, when booking, to share the vehicle with others on the basis that each pays a separate fare. That's section 11 of the Transport Act 1985, and it applies to licensed taxis and to licensed hire cars, which include private hire vehicles licensed under the 1976 Act or the London Act.

Under those conditions the car doesn't become a public service vehicle and stays under the private hire rules. Outside them, a car carrying passengers at separate fares in the course of a business is a public service vehicle under section 1 of the 1981 Act.

Taxis have a second route in section 10 of the 1985 Act: schemes, made by the licensing authority, that let taxis be hired immediately at separate fares from authorised places. An authority must make one if the holders of at least 10% of its taxi licences ask in writing. Private hire has no equivalent.

Where does cost sharing fit?

Cost sharing is the lift-share exception, and it sits in the bus and insurance laws, not the private hire Acts.

The private hire Acts have no cost-sharing exemption. Section 75 of the 1976 Act exempts things like weddings and funerals, but not lift sharing. Liftshare, the UK carpooling service, tells its members that overcharging could be viewed as operating a taxi service without a licence. So the safe reading is the one both Acts give: costs only, agreed in advance, and no profit for the driver. The practical rules for apps are in our guide to carpooling and lift-share apps.
