What is a hackney carriage driver licence?

A hackney carriage driver licence allows a person to drive a hackney carriage — commonly known as a taxi — that can be hailed in the street or can wait on a taxi rank for fares. This is the key difference from a private hire vehicle, which must be pre-booked.

What it allows

With a hackney carriage driver licence you can:

  • Pick up passengers who hail you in the street.
  • Wait on a taxi rank and pick up fares.
  • Take pre-booked jobs where permitted.

Who issues the licence

Hackney carriage driver licences are issued by the local licensing authority. In London, the equivalent is the London taxi driver licence administered by Transport for London, which requires the Knowledge of London. Smart Taxi Solutions does not issue these licences.

Common requirements

Requirements vary by council but commonly include:

  • Minimum age (often 18 or 21).
  • A full driving licence held for a qualifying period.
  • An enhanced DBS check.
  • A medical assessment.
  • A knowledge test (in London, the Knowledge of London).
  • Safeguarding awareness.

Requirements vary by council. Always confirm the current requirements with the relevant licensing authority.

Hackney carriage vs private hire

The main practical difference is how fares are obtained: hackney carriages can be hailed and use ranks; private hire vehicles must be pre-booked. Some councils issue a dual driver licence combining both. See What Is a Dual Taxi Driver Licence?

How long does it last?

Hackney carriage driver licences are normally granted for a fixed period, often three years, but this varies by council.
