The iconic black cab is a staple of Londonโs streets, a symbol of the city as recognisable as a red bus. For many visitors and residents, it is the preferred mode of transport for its convenience and direct service. Yet the method behind the cost of a journey can appear enigmatic, governed by the quiet tick of the meter. This system, however, is built on a foundation of clear regulation and straightforward calculation.
Understanding the principles that determine the cost of a licensed London taxi demystifies the process entirely.
How are London Taxi Fares Calculated?
The fare shown on a licensed London taxi meter is calculated based on distance travelled, time taken, and the time of day. The meter applies different โtariffsโ depending on when you travel, ensuring the total cost reflects both how far you go and how busy the roads are.
Here is a simple table showing how fares are worked out under current fare rules by Transport for London (TfL):
| Tariff | Rate per Mile | Times when Tariff Applies |
| Tariff 1 (up to 6 miles) | ยฃ4.00 | Monday to Friday, 05:00โ20:00 |
| Tariff 2 (up to 6 miles) | ยฃ4.83 | Monday to Friday, 20:00โ22:00 Saturday and Sunday, 05:00โ22:00 |
| Tariff 3 (up to 6 miles) | ยฃ5.12 | Every night 22:00โ05:00 Public holidays |
| Tariff for journeys over 6 miles | ยฃ4.83 | At all times for journeys over 6 miles |
Insights into the Fare Structure of the London Black Cab
When you step into a licensed London taxi, the cost of your journey is not decided by the driverโs mood. Instead, there is a regulated system overseen by Transport for London (TfL) that sets clear rules for how fares are worked out. A meter begins when you hire the cab and records a running total.
Passengers often ask, Do London taxis charge by time or distance? The answer includes both factors. The fare is calculated based on a combination of distance travelled, time spent (especially when traffic is slow or in heavy congestion), and the time of day or day of week.
1. Distance-Based Fares in London Black Cabs
One part of the London black cab fare structure relies on distance travelled. The meter calculates the cost per mile based on the applied tariff. Short journeys up to six miles are charged under Tariff 1, 2, or 3, depending on the time and day. For longer trips exceeding six miles, a slightly different per-mile rate is applied, ensuring fares remain fair over extended distances.
The more miles the cab covers, the higher the fare. The meter automatically records each unit of distance and multiplies it by the current tariff rate.
2. Time-Based Fares in London Black Cabs
The other component of the London black cab fare structure depends on time. When the taxi moves slowly due to traffic congestion, stops at signals, or waits for passengers, the meter switches to a time-based charge. This ensures the driver is fairly paid while passengers pay proportionally for delays.
Tariffs adjust based on the time of day, with higher tariffs applying during evenings, nights, weekends, and public holidays. Being aware of this can help passengers understand why fares fluctuate even on similar routes at different times.

What This Means for You as a Passenger
Understanding the fare system helps you make smart choices.
- If you travel in offโpeak hours and roads are clear, the fare will likely be close to the lower end of the typical range.
- If traffic is heavy or you travel late at night, expect to pay more per mile or per minute.
- For longer journeys, the perโmile rate might change mid-ride, so the final fare could differ from a simple โdistance ร rateโ estimate.
- Using a licensed taxi meter ensures you pay a fair fare; you can check it during the ride.
- If you need a rough idea of cost before you travel, knowing the typical fares for 1, 2, 4, or 6 miles helps you approximate.
