The iconic black cab is a symbol of London. Drivers face high costs and intense competition. While some see the job as a way to earn a steady living, others find the overheads difficult to manage. We look at the real numbers behind the wheel.

The cost of the Knowledge

Studying for the licence is hard. It takes between two and four years of intense study because drivers must memorise 25,000 streets and thousands of landmarks. Most people cannot do this without significant mental effort.

The lost income is a massive hurdle. While a student learns the routes, they are not earning a taxi fare, so they often work other jobs to survive. This period represents a huge financial sacrifice before the first pound is ever earned from a passenger.

Training costs money too. Drivers pay for various courses and assessments throughout their study years. It is a steep entry price.

Gross income versus take-home pay

Gross earnings vary by driver. According to figures from the London Taxi and Private Hire Association (LTDA), a typical week might see gross takings between £800 and £1,200. These numbers depend on how many hours a person works in busy areas like Mayfair or Canary Wharf.

The take-home pay is much lower. Drivers must pay for vehicle rent, which typically runs £250 to £400 per week for a modern LEVC TX5 depending on the agreement. They also face high insurance premiums and National Insurance contributions that eat into their margins.

Fuel remains a heavy burden. Even with newer models, the cost of keeping a vehicle moving through London traffic is constant.

Shift patterns and working hours

The job requires long days. Most drivers work between 45 and 60 hours every week to maintain a decent standard of living. Some prefer the day shift because it offers more predictable passenger flows from hotels and train stations.

Night shifts offer a different dynamic. Drivers often earn a premium during late-night hours when demand spikes around Soho or Shoreditch, although they must deal with more difficult passengers. Many drivers split their week to catch both peak periods.

Rest is essential. If you work too much, the fatigue becomes dangerous.

The impact of Uber and electrification

Uber changed everything in 2012. Private hire vehicles flooded the streets, which increased competition for every passenger. This shift forced many black cab drivers to adapt by using apps alongside traditional street hails.

The COVID-19 pandemic caused a massive dip. During lockdowns, passenger numbers fell so sharply that many drivers had to stop working entirely for several months. The recovery has been slow but steady since 2021.

Vehicle technology is also shifting. Older diesel TX4 models are expensive to run because of fuel costs and ULEZ charges. The newer LEVC TX is a range-extended electric vehicle — an electric motor drives the wheels, supported by a small petrol generator when the battery runs low. This setup helps reduce running costs in the central London zones.

Comparing vehicle economics

The TX5 is more efficient. Because it uses a hybrid system, drivers spend less on petrol compared to older diesel engines. This change helps when moving through the heavy congestion of the City or Westminster.

Maintenance costs differ too. Electric components require different care than traditional internal combustion engines. Drivers must weigh the high upfront cost of a new LEVC against the daily savings on fuel and emissions penalties.

The choice is often financial. A driver must decide if the savings justify the debt.

Frequently asked questions

How much does it cost to rent a black cab weekly?
Rent varies significantly depending on whether you lease a vehicle or use a traditional firm. Most drivers pay between £250 and £400 per week for a TX5 model.
Can I earn more by working at night?
Night shifts often provide higher gross takings due to increased demand in nightlife districts like Hackney Wick. However, the work can be more taxing on your health.
What is the ULEZ charge for older taxis?
Older diesel TX4 vehicles may face daily charges if they do not meet Euro 6 standards. Most modern black cabs are compliant, so they avoid these specific London congestion and emissions costs.
Is the Knowledge still necessary for all drivers?
Yes, you must pass The Knowledge to drive a licensed Hackney carriage. This is different from private hire drivers who use apps but do not need to memorise the streets.
How many hours does an average driver work?
Most full-time drivers aim for 50 hours per week. Working fewer hours often makes it difficult to cover the high weekly costs of rent and insurance.
Do black cabs earn more than Uber drivers?
Black cabs can pick up passengers on the street, which provides a steady stream of work. Uber drivers rely entirely on app bookings, so the earning styles are quite different.
What is the main expense for a driver?
Vehicle rent and fuel are usually the two largest weekly outgoings. After these, insurance and maintenance take up a significant portion of the gross income.
