If you work in the world of taxis and private hire in the UK, the rules can seem confusing.
You’ll hear people talk about black cabs, hackney carriages, minicabs and private hire vehicles PHVs. Many passengers think they’re all the same, but in the eyes of the law, they’re very different.
This guide explains taxi vs private hire vehicle PHV in clear terms, so you know exactly what each can and can’t do, and what that means for you as a driver or passenger.
What Is a Taxi (Hackney Carriage)?
A taxi, also known as a hackney carriage, is the only type of vehicle that can legally ply for hire. That means:
- It can be hailed on the street by a passenger.
- It can wait on taxi ranks, ready for immediate hire.
- It normally has a roof sign and a licence plate attached at the back so you can see it’s a genuine licensed vehicle.
Inside, there will be a meter. When you get in, the driver starts the journey and you can see the amount showing on the meter during the trip. At the end, you pay the amount showing, based on the local tariff set by the licensing authority.
In many cities, taxis are the classic black cabs you see with a clear roof sign and prominent licence plates. Some councils require an extra badge or sticker in the front windscreen so passengers can easily check that the taxi is properly licensed and insured.
Because taxis can be hired without a prior booking, they have strict standards for vehicle condition, accessibility and motor insurance. The driver must hold the correct driver licence for hackney carriage work, and the vehicle must be insured for taxi use, not just social or private hire.
What Is a Private Hire Vehicle (PHV)?
A private hire vehicle (PHV), sometimes called a minicab, works differently:
- It cannot be hailed on the street.
- It cannot wait on taxi ranks.
- Every journey must be a prior booking through a licensed operator.
That means the passenger must contact the operator (by app, phone or website) before the trip starts. The operator then sends details to a private hire driver who will carry out pre‑booked journeys only.
Like taxis, PHVs must display a licence plate attached to the rear of the vehicle, and often a smaller sticker or plate in the front windscreen, so enforcement officers and passengers can see it’s properly licensed. However, PHVs won’t usually have a taxi‑style roof sign.
The driver carrying passengers in a PHV must hold the correct private hire driver licence.
Their motor insurance must cover them for private hire, not just normal social driving. Using a standard policy while carrying paying passengers would almost certainly invalidate cover.
How to apply for licences for a taxi or private hire vehicle
According to the Government website you can apply to the licensing authority where you plan to work through either:
- the local council if you want to work outside of London
- Transport for London (TfL) if you want to work in London
If you want both a taxi and PHV driver licence, you might need to apply separately for each.
Taxis vs Private Hire Vehicles PHVs: Key Differences at a Glance
How you book
Taxis
Can be hailed on the street or taken from taxi ranks, as well as pre‑booked.
PHVs
Must have a prior booking via a licensed operator, they cannot ply for hire.
Signs and plates
Taxis

PHVs

Payment
Taxis

PHVs
Price is agreed in advance or displayed in the app at the time of booking.
Legal permissions
Taxis
Can ply for hire, use ranks and accept immediate hires.
PHVs
Can only carry out pre‑booked journeys, enforced by licensing rules and insurance conditions.
Why the Difference Matters
For passengers, knowing the difference helps you stay safe and avoid unlicensed vehicles. Always check for licence plates and, with PHVs, make sure your trip appears in the app or is confirmed by the operator before you get in.
For taxi drivers and private hire drivers, the distinction is critical:
- Your licence type, vehicle plate and motor insurance must all match the work you do.
- A taxi driver working a street rank needs hackney carriage insurance; a PHV driver taking app jobs needs private hire insurance and operator records to show the booking.
- If a private hire driver accepts a street hail, that journey may be treated as illegal plying for hire, and their insurance may not cover the trip.
Put simply: taxis and private hire vehicles PHVs are both important parts of the transport system, but they play by different rules. Understanding those rules protects drivers, passengers and operators and keeps you on the right side of the law.
