London taxi passengers could see fares rise by around 4% from April 2026, as inflation and increased operating costs put more pressure on the capital’s cab trade.
According to Transport for London’s (TfL) latest ‘cost index’, which reviews annual changes in operating expenses and average national earnings, a 4.01% fare rise could be introduced next spring. The data combines an estimated 0.91% increase in operating costs with a 3.10% rise in national average earnings, producing the projected figure.
The cost index plays a key role in determining future taxi tariff adjustments. It considers several factors including fuel prices, insurance, vehicle maintenance, and general economic conditions.
A public consultation on the proposed changes is expected later this year, with the final decision to be made ahead of the start of the new financial year in April 2026.
Previous Fare Rises
The potential 2026 increase would follow the 5.6% fare rise approved in April 2025, which TfL said was necessary to support drivers amid soaring costs. At that time, many drivers and unions argued that even higher rises were justified due to record inflation and the push towards zero-emission capable (ZEC) taxis, which remain significantly more expensive to buy and maintain.
In 2025, there were suggestions that some tariffs could have risen by as much as 7.5%, particularly for longer journeys, but TfL ultimately settled on a lower figure to balance driver income and passenger affordability.
Impact on Drivers and Passengers
While a 4% increase may appear modest, it reflects ongoing challenges faced by the London taxi trade. Drivers are dealing with:
- Higher insurance premiums
- Rising vehicle purchase and maintenance costs
- Increased electricity and fuel prices
- Tougher environmental and licensing standards
For passengers, it means fares will once again edge upwards, continuing the trend of annual increases driven by inflation and the cost of living.
What Happens Next
TfL is expected to begin its formal consultation on the 2026 fare adjustment later this year. Once reviewed, the TfL Board will make the final decision on whether to approve the proposed 4% increase or make further adjustments based on updated economic data.
If approved, the new tariffs would come into effect in April 2026, affecting all London taxi meters across the city.
