UK taxis (also called hackney carriages or black cabs) can be flagged down on the street or hired from taxi ranks. Private hire vehicles (minicabs, Uber, Bolt, FreeNow) must always be pre-booked through a licensed operator. That single rule drives most of the other differences between the two, including pricing, licensing, vehicle type, and insurance.
This guide breaks down the differences UK drivers and passengers should understand, with a particular focus on the insurance side, since the cover each type of driver legally needs is distinct.
What's the difference between a taxi and a private hire vehicle?
Hackney carriages (taxis) and private hire vehicles (PHVs) are both licensed to carry passengers for payment in the UK, but they operate under different rules.
How they're hired
- Taxis / hackney carriages can be flagged down on the street, hired from a taxi rank, or pre-booked. This is called "plying for hire" and it's the defining legal difference between a black cab and a minicab.
- Private hire vehicles must always be pre-booked through a licensed operator or ride-hailing app. They cannot legally be flagged down on the street or wait on a taxi rank for passengers.
Fare pricing
- Taxis use a meter set by the local council, charging a fixed rate per mile plus time standing in traffic. Rates vary by area and time of day, and longer journeys may be quoted upfront.
- Private hire fares are agreed in advance through the operator or ride-hailing platform. Drivers can't legally charge more than the quoted amount.
Licensing
Both types of driver need separate licences.
Taxi drivers in London need a TfL Taxi Driver Licence, famously requiring passing "the Knowledge", a comprehensive test of London streets that can take drivers years to complete. Outside London, local councils issue taxi licences with varying local knowledge requirements.
Private hire drivers need a Private Hire Driver Licence (PHL), or a PCO licence in London, issued by TfL or the local council. For the full step-by-step walkthrough, our guide on how to become a UK private hire driver covers the four-step licensing route (eligibility, council or TfL application, joining an operator, vehicle registration and insurance). For the taxi route specifically, our guide on how to get a UK taxi licence walks through the application.
Understanding taxis: the role of hackney carriages
Hackney carriages have a UK history going back to the 17th century. You can typically identify them by their roof sign, the taxi licence plate attached to the rear, and a licence card displayed in the front windscreen. In London, the iconic "black cab" is purpose-built to meet TfL's Conditions of Fitness standards, including the tight turning circle required for the capital's historic streets.
Passengers can hail a taxi on the street, pick one up from a taxi rank, or pre-book one. The meter starts when the journey begins, and the final fare reflects distance travelled plus time spent in traffic.
Private hire vehicles and ride-hailing apps
Private hire vehicles can be any make or model that meets local licensing requirements, but they must always be pre-booked. They display their licence details clearly, usually on a disc inside the vehicle or on a licence plate at the rear.
The rise of ride-hailing apps like Uber, Bolt and FreeNow has changed how most UK passengers interact with private hire. The apps connect drivers and passengers directly, with fares quoted and agreed upfront. Drivers on these platforms still need to hold a full PHL or PCO licence and meet all the usual private hire regulations.
Earnings also differ between the two. UK private hire drivers on ride-hailing platforms typically earn around £13.54 an hour on average per Talent.com's 2026 data, with wide variation by city, shift pattern and platform. For the full breakdown of Uber driver salary in the UK, our earnings guide walks through hourly, weekly and annual figures after costs. Black cab earnings vary differently thanks to metered fares and the mix of street-hail and pre-booked work.
What's the difference in insurance between a black cab and a private hire vehicle?
Insurance is where the two worlds diverge most. Both types of driver need specialised hire and reward (H&R) motor insurance, because a standard personal policy (social, domestic and pleasure, or SD&P) doesn't cover carrying passengers for payment. But the specific cover each needs is different.
Black cab (hackney carriage) insurance
Taxi insurance is underwritten specifically for drivers who can be hailed on the street. Because black cabs typically operate in dense urban areas and accept passengers without advance booking, the risk profile is higher than private hire. That typically reflects in:
- Higher public liability limits on many policies, to reflect the volume of varied passengers.
- Cover for plying for hire (street-hail pick-ups), which private hire policies don't include.
- Higher base premiums than equivalent PHV cover in many cases.
- Specialist policy wording for London's Conditions of Fitness vehicles and meter-based fares.
Zego offers private hire insurance but does not currently underwrite hackney carriage (black cab) insurance. Black cab drivers typically use specialist taxi insurance brokers who underwrite hackney carriage risk directly.
Private hire insurance
Private hire insurance covers pre-booked passenger work only. It's a legal requirement for any UK driver carrying fare-paying passengers on a pre-booked basis, including Uber, Bolt and FreeNow drivers.
Typical private hire insurance includes:
- Hire and reward commercial passenger work.
- Social, domestic and pleasure personal driving (on combo policies).
- Third party or fully comprehensive cover levels.
- Cover for pre-booked fares through licensed operators, including ride-hailing apps.
The cost varies by driver age, area, vehicle, claims history and cover level. Our guide on what insurance UK taxi drivers need covers the detail for both taxi and private hire drivers.
Why are the two treated differently?
The split comes down to risk. A black cab picks up unknown passengers from the street, sometimes late at night, sometimes in high-volume central urban zones. Private hire drivers typically know who their passenger is before pick-up (name, pick-up address, drop-off), which materially reduces several types of underwriting risk. Insurers price those two profiles differently, which is why the products are sold separately.
Save on private hire insurance with Zego Sense
Traditional insurance typically prices on industry averages and the behaviours of other drivers, not on how well you personally drive. That's not always the fairest way to set a premium.
Zego Sense is different. It's Zego's app-based cover for safe drivers. The Zego Sense app uses your smartphone's sensors to measure how you drive and builds a driver rating over time. The higher your rating, the more you can save at renewal.
Here's how it works:
Download the app. Install the Zego Sense app on your phone to start a Sense policy. You'll get a discount upfront to get you started.
Build your driver rating. The app measures your driving over time and gives you a rating based on acceleration, braking, cornering, speeding and rest. Safer driving means a higher rating.
Drive well, save at renewal. Your renewal price reflects your driver rating, so the better you drive, the better your chance of unlocking Zego's lowest prices.
For UK Uber, Bolt and FreeNow drivers, UK private hire insurance from Zego combines H&R cover for your paid work with SD&P cover for personal driving on one policy.
