Navigating London's bustling streets often involves hopping into a taxi, whether it's the iconic black cab or a pre-booked private hire vehicle. Yet, for many, the cost determination of these essential services remains a bit of a mystery. Understanding how your fare is calculated can empower you to make informed travel choices, avoid unexpected charges, and appreciate the value of the service you receive. This guide aims to demystify London's taxi fare structures, offering clarity on both traditional and specialised transport options.

London's taxi landscape is primarily divided into two main categories: licensed London Black Cabs and Private Hire Vehicles (PHVs), often referred to as minicabs. Each operates under a distinct pricing model regulated by Transport for London (TfL), and understanding these differences is crucial for any passenger.
How Black Cab Fares Are Determined
Black Cabs, known for their distinctive shape and the 'for hire' light, operate on a strictly metered system. This means the fare is calculated by a regulated taxi meter that combines both the distance travelled and the time taken for the journey. TfL sets the maximum fares, which are displayed on a tariff card inside the cab. These tariffs vary based on the time of day, day of the week, and public holidays.
Understanding the Tariff System:
- Tariff 1 (Day Rate): Typically applies from 05:00 to 20:00, Monday to Friday. This is the base rate for standard daytime travel.
- Tariff 2 (Night/Weekend Rate): Applies from 20:00 to 22:00, Monday to Friday, and from 05:00 to 22:00 on Saturdays and Sundays. This rate is slightly higher to reflect the increased demand and operational costs during these times.
- Tariff 3 (Late Night/Public Holiday Rate): Applies from 22:00 to 05:00, Monday to Sunday, and all day on public holidays (including Christmas and New Year's Eve). This is the highest tariff, acknowledging the significant operational challenges and demand during these peak periods.
The meter continuously calculates the fare based on the current tariff. If the taxi is moving, it charges by distance; if it's stationary or moving very slowly (e.g., in traffic), it switches to a time-based charge. This ensures that drivers are compensated fairly, regardless of traffic conditions, and passengers receive a transparent fare based on the actual journey. There is also a minimum fare charge for all journeys, regardless of how short they are.
Additional Charges for Black Cabs:
While the meter covers the primary journey cost, certain surcharges may apply:
- Booking Fees: If you pre-book a black cab, the operator may add a small booking fee, which should be clearly communicated at the time of booking.
- Heathrow Airport Surcharge: A specific charge is usually added for journeys originating from Heathrow Airport, contributing to the costs of the taxi ranks and facilities.
- Credit/Debit Card Surcharge: While many black cabs accept card payments, some may still levy a small surcharge for this service, though this is becoming less common due to regulations encouraging card payments.
- Congestion Charge/ULEZ: Drivers of licensed taxis often factor these costs into their overall business expenses and do not typically add them as a separate line item to the passenger's fare, unlike some other private vehicles.
It's important to note that black cab drivers are legally obliged to take any fare up to 12 miles (or 20 miles if originating from Heathrow) and cannot refuse a fare based on its length or destination within the Greater London area, provided it's within their operating hours.
How Private Hire Vehicle (Minicab) Fares Are Determined
Unlike black cabs, Private Hire Vehicles (PHVs) are not permitted to use a meter on public roads to calculate fares. Instead, their fares are usually agreed upon before the journey commences. This means you should always obtain a quote from the operator or driver prior to getting into the vehicle. This pre-agreed fare can be fixed or based on an estimated distance/time.
Common PHV Pricing Models:
- Fixed Price: The most common method. You are given a set price for your journey when you book, regardless of traffic or minor route variations. This offers excellent fare transparency and predictability.
- Estimated Price: Some operators might provide an estimate, especially for longer or more complex journeys, with the final price subject to variations. Always clarify if this is an estimate or a fixed quote.
- Hourly Rate: Less common for point-to-point journeys, but often used for executive hire, airport transfers with waiting time, or bespoke tours where the vehicle is hired for a block of time.
Factors influencing PHV quotes include:
- Distance and Estimated Time: The primary determinants.
- Time of Day/Week: Similar to black cabs, PHVs often have higher rates during peak hours (e.g., rush hour, late nights, weekends, public holidays) due to increased demand and potential for traffic.
- Booking Method: Online bookings or app-based services might offer different rates or promotions compared to phone bookings.
- Vehicle Type: Larger vehicles, executive cars, or specialist vehicles (like those for wheelchair access) will naturally have higher rates.
- Additional Services: Waiting time (if not pre-agreed), multiple stops, or specific pick-up/drop-off requirements can add to the cost.
It is illegal for a PHV driver to charge a fare that was not agreed upon prior to the journey, or to use a meter to calculate a fare on the street. Always book a minicab through a licensed operator to ensure your safety and fair pricing.

Understanding Your Fare: Tips for Passengers
Armed with this knowledge, here are some practical tips to ensure a smooth and cost-effective taxi experience in London:
- For Black Cabs: Trust the meter. It's legally regulated. Familiarise yourself with the basic tariff times (day, night, public holiday) to have a general idea of potential costs. Don't be afraid to ask the driver if you're unsure about any potential surcharges, though most are straightforward.
- For Private Hire Vehicles: ALWAYS get a quote before you book and before you start your journey. Confirm that the price is fixed, especially for airport transfers or longer trips. Be wary of any PHV driver who approaches you on the street offering a ride, as this is illegal and unregulated.
- For Specialised Services (like A91 Taxi’s): Clearly communicate all your requirements when booking. This includes the number of passengers, specific mobility needs (e.g., wheelchair dimensions, need for a ramp/lift), and any additional equipment. This ensures they dispatch the correct vehicle and provide an accurate quote for the tailored service.
- Payment Methods: Confirm accepted payment methods (cash, card) before starting your journey, especially for PHVs. Most black cabs now accept card payments.
Frequently Asked Questions (FAQs)
Are London taxi fares negotiable?
No, black cab fares are strictly regulated by TfL and are calculated by the meter; they are not negotiable. For private hire vehicles, the fare is agreed upon before the journey, so while you can compare quotes from different operators, the agreed price for that specific booking is generally not negotiable once set.
Do Black Cabs charge extra for luggage?
Generally, black cabs do not charge extra for standard luggage. However, very large or excessive items that significantly impede the driver's space or require special handling might be subject to a small additional charge, though this is rare and should be communicated by the driver.
How are airport surcharges applied?
For black cabs, a specific surcharge (e.g., for Heathrow) is automatically added by the meter or as a fixed charge when departing from the airport's designated taxi ranks. For private hire vehicles, any airport-related charges (like parking fees or drop-off/pick-up charges) would typically be included in your pre-agreed fixed quote.
What's the key difference between a minicab and a black cab's pricing?
The key difference is regulation and transparency. Black cabs use a visible, regulated meter, so the fare accrues during the journey. Minicabs operate on a pre-agreed fixed fare, meaning you know the exact cost before you even start the trip. Minicabs cannot use meters on public roads.
How can I ensure accessibility with A91 Taxi’s?
To ensure A91 Taxi’s can meet your specific accessibility needs, it is crucial to clearly outline them when you make your booking. Specify if you require a wheelchair-accessible vehicle, if you need a ramp or lift, and any other particular assistance. This allows them to dispatch the most appropriate vehicle and driver for your comfort and safety.
Is there a minimum fare for London taxis?
Yes, black cabs have a minimum fare regardless of the distance travelled. This covers the initial cost of engaging the taxi. Private hire vehicles also typically have a minimum charge built into their fixed quotes.
Understanding the nuances of London's taxi fare determination empowers you to choose the best transport option for your needs, whether it's a spontaneous black cab ride or a pre-booked, specialised service like A91 Taxi’s.
