Executive Summary
Transport for London (TfL) is the statutory licensing authority for London’s black cabs. It regulates taxis by setting driver and vehicle standards, running the Knowledge of London test, issuing licences, enforcing compliance, and managing a formal passenger complaints process to protect safety.
Step into any black cab in the capital, and you’re not just booking a ride, you’re stepping into a system built on decades of standards, testing, and quiet oversight. Behind that iconic black exterior sits a rigorous framework most passengers never think twice about, until something goes wrong or they simply wonder how it all works. That framework belongs to Transport for London.
Best known for the Tube map and red buses, TfL is also the unseen hand shaping who drives you, how well they know the city, and what happens if things go sideways. Knowing how this authority operates puts both passengers and future drivers firmly in control.
What Is TfL and What Does It Do for London Taxis?
Transport for London is the statutory body responsible for transport across the capital, established under the Greater London Authority Act 1999. Beyond running buses, trains, and river services, TfL is the official licensing authority for taxis and private hire vehicles, licensing every taxi driver, every taxi vehicle, and overseeing the standards that keep passengers safe.
TfL does not operate London’s black cabs itself. Instead, it licenses and regulates the taxi trade, sets requirements for drivers and vehicles, monitors compliance and takes enforcement action where appropriate.
How Does TfL Regulate Taxis in London?
It can be broken down into four main functions that shape the regulator’s day-to-day approach:
- Setting standards for drivers, vehicles, and operators
- Running the licensing process, including background checks and medical assessments
- Carrying out enforcement, spot checks, and compliance reviews
- Managing the complaints system to protect passengers
TfL’s Conditions of Fitness set requirements for London taxis, including accessibility and vehicle design. All licensed London taxis are designated as wheelchair accessible and must be equipped to approved standards so wheelchair passengers can be carried.
TfL carries out checks on vehicles and drivers to monitor compliance with licensing requirements. Where drivers or vehicles do not comply with applicable licensing requirements, TfL can take enforcement or licensing action. The action taken depends on the nature and circumstances of the breach.

What Is the TfL Taxi Licensing Process?
Becoming a licensed taxi driver in London is a long process, and few people realise just how many stages sit between application and badge. Understanding the licensing process helps explain why black cab drivers are held in such high regard. Broadly, the journey includes the following stages:
A driver must meet TfL’s applicable licensing requirements and hold a valid taxi driver’s licence before working as a licensed London taxi driver.
What Are the TfL Knowledge Test Requirements?
This is the part most people find fascinating. The Knowledge of London is a detailed qualification process that tests a taxi driver’s knowledge of London’s roads, routes and points of interest. For the All London Knowledge, applicants must learn 320 routes, known as runs, along with destinations within a six-mile radius of Charing Cross. They must also learn additional suburban routes, including routes to and from Heathrow and London City airports.
How Long Does It Take?
The time required varies between applicants. TfL says candidates can organise their study around their other commitments, while the Knowledge itself is completed through a series of stages and examinations.
Key Elements of the Test
- Learning 320 core routes, known as “runs”
- Learning relevant roads, routes and points of interest
- Completing the required Knowledge examinations and assessments
- Attending the required verbal “Appearances” before TfL examiners
Successful All London Knowledge candidates receive a green badge, while successful Suburban Knowledge candidates receive a yellow badge.
What Is the TfL Taxi Complaints Process?
Even with strong standards, things occasionally go wrong, and passengers deserve a clear way to raise concerns. The TfL taxi complaints process is designed to be straightforward and accessible.
How to Make a Complaint
- Note the taxi’s licence plate or other identifying vehicle details
- Record the driver’s badge number if possible
- Submit details through TfL’s official complaints form or contact its Surface Transport customer service team
- TfL will investigate the complaint and may contact you for further information
- TfL may take appropriate action based on the circumstances and available evidence
TfL uses information from complaints and reports to investigate potential breaches of its taxi licensing requirements.
