Over the past two decades, the UK taxi trade has undergone a silent structural shift — the Great Displacement. Professional, locally licensed taxis have been pushed to the margins of the market they built, not through innovation but through uneven regulation and a lack of structural protection for professional standards.
Ride-hailing is often credited with “disruption”, but the reality is simpler: policy failure created an unbalanced market in which scale and price outweighed standards and accountability. This imbalance has left the country’s most experienced drivers — those who meet the highest licensing, accessibility and safety requirements — at risk of being priced out of the profession they helped to build. Without reform, the UK risks losing a service that once set the global benchmark for reliability and trust.
Protecting the taxi trade now depends not on nostalgia or subsidy but on reconnecting Tier 1 taxis — professionally trained, locally licensed drivers operating to the highest standards — to Tier 1 work, the high-trust public-service journeys where those standards matter most.
The real imbalance
A recent BBC report highlighted proposals from London Assembly Members to protect the black-cab trade by capping the number of private-hire vehicles (PHVs). The instinct is understandable. The trade represents professionalism, accessibility and trust — qualities that have defined London’s transport system for generations.
The issue is not simply how many PHVs exist, but the structure that allows their numbers to grow unchecked under rules that do not apply to taxis. PHV licensing has been shaped by sustained industry lobbying, while taxi representation has remained fragmented. The result is a system where scale, not standards, determines success.
Across England there are around 313,000 licensed taxis and PHVs, up eight per cent in the past year, and roughly 82 per cent are PHVs, according to Department for Transport data. Taxi numbers have fallen by 15 per cent while PHVs have expanded rapidly because of lower barriers to entry — cheaper vehicles, lighter vetting and no local-knowledge requirement.
This regulatory drift has also eroded accessibility standards. Every licensed London taxi — 100 per cent of the fleet — is wheelchair accessible. Among London’s private hire vehicles, the figure is just 0.4 per cent, according to Transport for London’s Taxi and Private Hire Action Plan (2025). Yet the market has expanded in favour of the less accessible fleet. That inversion illustrates the core policy failure: regulation has rewarded volume, not value, and displaced the vehicles best equipped to serve the public interest.
Hackney carriages can be capped under Section 16 of the Transport Act 1985, but only if a council can prove that demand is “sufficiently met”. In practice, most councils no longer use this power, and London has never imposed a cap. There is no mechanism at all to limit PHVs, and that imbalance drives the distortion.
Taxis must charge metered fares set by local authorities. PHVs can charge whatever they like, often using dynamic pricing. Meanwhile, the long-standing rule that PHVs must be pre-booked has been blurred by ride-hailing apps, where an “instant booking” now feels identical to a street hail.
The problem is amplified by cross-border licensing. PHVs can obtain a licence in one area and work almost entirely in another — for example, a driver licensed in Wolverhampton operating in London through an operator also licensed there. This allows PHVs effectively to work anywhere, while taxis remain tied to their own licensing area for street work. A London taxi can take pre-booked jobs outside the capital only by switching to PHV status — losing its metered rates and Tier 1 standing in the process.
These regulatory differences are not accidental. They are the product of sustained lobbying and permissive policy that favour national, low-barrier operations over locally accountable, professional services. PHVs now function as a lightly regulated national network. Taxis remain locally accountable, held to higher standards for fairness, safety and service. The two compete on unequal terms, while most local authorities remain agnostic about who wins — since both draw from the same pool of demand
The limits of capping PHVs
Capping the number of PHVs to protect the black-cab trade is a well-intentioned idea, but it cannot work in practice. Creating a PHV cap would require primary legislation — a slow and uncertain process. Even then, enforcement would remain almost impossible while operators can use cross-border licensing to work anywhere in the country.
The problem is not the number of PHVs but the absence of local accountability. Taxis are bound to their licensing areas; PHVs are not. This imbalance cannot be corrected by numerical limits. Real reform means redesigning how work is allocated — ensuring that Tier 1 taxis connect directly to Tier 1, high-trust public-service contracts, while PHVs continue to serve low-risk, mass-mobility demand.
Tier 1 work for tier 1 taxis
Tier 1 taxis should be directly connected to Tier 1 public-sector work — the areas where high standards are essential: NHS non-emergency patient transport, SEND home-to-school travel, medical couriering, and local-authority care journeys.
Today these services suffer from spiralling costs, inefficiency, and limited transparency. Integrating licensed taxis into these networks offers immediate, measurable gains: shorter waits, better passenger experience, traceable journeys and more efficient use of public funds.
This approach does not require new law — only smarter design. It is also resilient to automation: no algorithm can replicate professional care. This model rewards professionalism and restores taxis to their rightful place within public-service transport.
Immediate benefits
Connecting Tier 1 taxis to Tier 1 work strengthens both sides of the system. For the public sector, it delivers flexibility, safety and measurable savings. For drivers, it restores a pathway to sustainable, skilled employment — work that values accreditation and accountability over price.
PHVs will continue to provide mass-market, lower-risk journeys, while professional taxis focus on the high-trust services automation cannot replace. Together, this creates a balanced, efficient two-tier market.
A practical call to action
Mobility Exchange calls on London’s policymakers, the Department for Transport, NHS commissioners and local authorities to focus reform where it counts: structure, not symbolism. A connected, transparent two-tier system — where professional, accessible taxis deliver the work that demands professionalism — is achievable now. It requires no new law, only smarter commissioning.
If implemented, this model would improve public-service outcomes, reduce waste and give the taxi trade a sustainable, dignified role within the UK’s transport mix. This is not nostalgia for what the black cab was; it is a framework for what the trade can become — Britain’s trusted Tier 1 mobility service.
