DECISIVE DECISION NEEDED: Why TfL faces race against time to deliver urgent black cab supply decision as taxi production gap threatens to shrink London fleet
Transport for London (TfL) now faces a potentially significant black cab supply problem created by timing rather than demand. LEVC is ending final assembly of the current TX this month, while its next-generation purpose-built taxi is not scheduled to enter the UK market until the second half of 2027.
The Licensed Taxi Drivers’ Association (LTDA) and Freenow by Lyft UKI have both argued that TfL should respond by temporarily relaxing the 12-year age limit affecting older Euro 3, Euro 4 and Euro 5 diesel taxis. Their concern is that without enough new or suitable second-hand vehicles entering the market, taxis reaching their licensing deadline will leave the fleet faster than replacements can arrive.
That would make a reduction in fleet numbers difficult to avoid during the transition period unless vehicle availability improves through another route. LEVC has confirmed that its new taxi will not launch until the second half of 2027 and has yet to disclose an exact on-sale date, production ramp-up or initial supply volumes.
The impact of a smaller pool of available cabs could increase competition among drivers looking to rent vehicles, putting upward pressure on rental rates. At the same time, limited second-hand supply could lift asking prices for used TX models as drivers compete for vehicles capable of remaining licensed for several more years.
That also becomes particularly important for owner-drivers whose existing taxi is damaged beyond economic repair or written off. Insurance settlements are normally linked to vehicle valuations, but in a distorted replacement market the practical cost of finding another suitable licensed taxi can move ahead of historical or conventional valuations. Drivers could therefore find that a settlement does not necessarily provide enough purchasing power to replace a vehicle on a like-for-like basis leaving the driver out of job through no fault of their own.
The LTDA has warned that the availability of used TX models will not be sufficient to maintain existing fleet numbers as older taxis reach their age limits. Freenow General Manager Danny O’Gorman has backed that concern, saying limited second-hand stock risks leaving drivers without vehicles and could affect both livelihoods and passenger access to London’s wheelchair-accessible taxi service.
O’Gorman said: “However, with the TX6 not available until next year and the limited stock of second-hand vehicles will not be enough to sustain fleet numbers as older cabs reach their licensing age limits. Without proactive measures, this shortage risks leaving drivers without vehicles and impacting livelihoods with direct impact on passengers as well.”
He added: “To protect London’s world-class, wheelchair-accessible black cab fleet for the long term, we support calls for a temporary suspension of the 12-year age limit until the supply of new vehicles is fully restored.”
TfL’s current policy gives Euro 3, Euro 4 and Euro 5 diesel taxis a maximum operating age of 12 years. Zero-emission-capable taxis, Euro 6 vehicles and qualifying LPG taxis can remain licensed for up to 15 years. TfL says it retains general discretion to grant exemptions in exceptional circumstances, although the current system is intended to support reductions in harmful emissions.
There is consequently a policy trade-off for TfL. The shorter age limit was introduced to accelerate the removal of older diesel vehicles, and TfL says taxi NOx emissions fell 48% between 2019 and 2022 while CO2 emissions fell 41% and PM2.5 emissions fell 86%. Its 2025 Taxi and Private Hire Action Plan links the age-limit policy directly to improving air quality and accelerating the move towards zero-emission-capable taxis.
However, the present vehicle-supply circumstances are different from those that existed when the policy was designed. The issue raised by the LTDA and Freenow is not resistance to newer vehicles, but whether sufficient replacement vehicles physically exist during the gap between one generation of purpose-built taxi ending production and the next reaching drivers.
Vehicle costs also matter to passengers. Higher purchase prices, finance costs and rental charges do not automatically change the taximeter rate because London taxi fares are regulated by TfL. TfL itself is responsible for setting regulated taxi fares. But sustained increases in drivers’ operating costs can become relevant when future fare reviews assess the economics of providing the service.
That creates a wider risk as a constrained vehicle market could simultaneously reduce the number of taxis, increase rental and second-hand vehicle prices and add pressure to driver operating costs. The impact would be felt most sharply by drivers who suddenly need a replacement vehicle rather than those able to continue operating an existing TX.
There is also a timing issue around the new LEVC model itself. A launch in the second half of 2027 does not necessarily mean large numbers of vehicles will immediately be available to every driver requiring one. LEVC has said manufacturing details and exact launch timing will be announced later.
The scale and speed of the production ramp-up will therefore be just as important to fleet availability as the launch date.
The ball is now firmly in TfL’s side of the court and they consequently face the pressure to determine how it wants to manage the transition period and how any intervention would sit alongside its existing air-quality objectives. A temporary age-limit change, targeted exemptions or maintaining the existing policy would have different consequences for fleet supply, emissions and drivers’ vehicle costs.
