Hackney carriage vs private hire: what's the difference?

In the UK, "taxi" and "private hire" are not the same thing in law, even though passengers often use the words interchangeably. The difference matters enormously if you are deciding how to start driving for a living. It changes how you find work, how your fares are set, what vehicle you can use, and which licence you apply for. This guide explains the two routes in plain terms so you can choose the one that fits your area and your plans.

The two types of licensed vehicle

There are two distinct categories of licensed passenger vehicle in England and Wales: the hackney carriage (the legal name for a "taxi") and the private hire vehicle (a "PHV" or "minicab"). Both are licensed by a local council, and in London both are regulated by Transport for London rather than a borough. The crucial legal difference between them comes down to one phrase: plying for hire.

Hackney carriages (taxis)

A hackney carriage is the only type of vehicle that is allowed to ply for hire. In practice that means a taxi can:

• Be hailed in the street by a passenger raising their hand;
• Wait on a designated taxi rank and pick up the next customer in the queue;
• Use a taximeter to calculate the fare based on time and distance;
• Also accept pre-booked journeys, just like a private hire car.

Because a taxi can be hailed or picked up at a rank, it can earn from passing trade without any prior booking. Hackney carriages are usually identified by a roof sign, a council plate on the rear and, in many areas, a distinctive colour scheme.

Private hire vehicles (PHVs / minicabs)

A private hire vehicle works very differently. By law a PHV must be pre-booked through a licensed private hire operator before the journey begins. A private hire car cannot ply for hire, which means it cannot be hailed in the street and cannot wait on a rank for passengers. Picking up someone who has not made a booking is a serious offence and can put a driver's licence and insurance at risk.

Private hire therefore depends on three licences working together: the driver's licence, the vehicle's licence, and the operator's licence that takes and records the bookings. Apps and phone-based firms are the modern face of this system, but the legal structure is the same.

Licensing differences

To drive either type of vehicle you must apply to the relevant council and satisfy them that you are a "fit and proper person". Many of the core checks are shared, including an enhanced criminal record check and a medical to a recognised standard. You can read the detail in our companion guide on the DBS check and medical for taxi drivers.

Where the routes diverge:

• Knowledge and assessments. Some councils ask hackney carriage applicants to sit a more demanding local knowledge or topographical test, on the basis that taxi drivers pick up strangers without a route planned in advance. Private hire applicants are often assessed too, and in London PHV drivers sit the SERU assessment. You can prepare for these with our practice tests.
• Vehicle standards. Hackney carriages often face stricter rules on wheelchair accessibility, signage and liveries, because they serve the public on demand.
• Separate licences. A driver's badge for one category does not automatically allow you to work in the other. Requirements differ from one council to the next, so always check the rules where you intend to work.

How fares are set

Fares are one of the clearest practical differences:

• Hackney carriage fares are capped by the council. The local authority sets a maximum tariff, and a taximeter applies it for any street or rank job. A driver cannot charge more than the metered fare for those journeys, although passengers can sometimes agree a lower price.
• Private hire fares are agreed at the point of booking. Because the journey is arranged in advance through an operator, the price is usually quoted by the operator or app. Private hire vehicles are not required to use a council tariff in the same way, and many do not carry a meter at all.

This means a taxi has a guaranteed pricing framework for hailed work, while private hire pricing is more flexible and is shaped by the operator's commercial model.

Which route should a new driver choose?

There is no single right answer; it depends on your area and how you want to work.

• Consider hackney carriage if you want the freedom to pick up at ranks and hails, you are based somewhere with strong passing trade such as a city centre, transport hub or nightlife district, and you are willing to meet the often stricter vehicle and knowledge requirements. Note that in many towns the number of taxi plates is limited, so they can be hard to obtain or expensive to lease.
• Consider private hire if you prefer to start through an established operator or app, you want a lower-friction route into the trade, and you are happy to rely on booked work rather than street hails. This is the most common entry point for new drivers.

Whichever path you take, the first step is the same: contact the right authority. Use our directory to find your council and check its specific rules, fees and tests.
