Urban mobility is a cornerstone of economic vitality, social inclusion, and environmental sustainability in the United Kingdom. With over 80% of the population living in urban areas, the way people move within and between cities directly affects productivity, quality of life, and the nation's ability to meet net-zero emissions targets. At the heart of this challenge stand the country's mayors — directly elected leaders in combined authorities such as Greater Manchester, the West Midlands, and London. These figures are increasingly central to securing the resources needed to build and maintain robust public transportation systems. Their ability to navigate complex funding landscapes, forge political consensus, and champion long-term investment strategies determines whether urban residents enjoy efficient, affordable, and green transit options or face congestion, delays, and declining services.

The Evolving Role of UK Mayors in Public Transport Funding

The powers and responsibilities of British mayors have grown significantly since the introduction of metro mayors under the Local Democracy, Economic Development and Construction Act 2009. While the Mayor of London has long enjoyed substantial transport authority through Transport for London (TfL), other city-region mayors have gradually acquired greater influence over local transport networks. Today, mayors are not merely figureheads but active negotiators who lobby central government, design regional transport strategies, and oversee multi-billion-pound investment programmes.

Devolution and Metropolitan Mayors

The devolution deals struck between the Treasury and combined authorities have transferred considerable transport-planning powers from Whitehall to regional mayors. For instance, the Greater Manchester Combined Authority, led by the Mayor of Greater Manchester, now controls the region's bus franchising, local rail services, and active travel infrastructure. The Manchester mayor's ability to secure funding from central government for projects like the Bee Network — an ambitious plan to integrate bus, tram, and cycling routes — illustrates how devolution enables mayors to tailor investment to local needs. Similarly, mayors in the West Midlands and West Yorkshire have used devolved powers to advance tram extensions, bus priority corridors, and station improvements. These successes, however, depend on mayors' capacity to make a compelling case for funding in a competitive national environment.

Advocacy and National Influence

Mayors also act as high-profile advocates for urban transport funding at a national level. Collective bodies such as the UK Metro Mayors and the Urban Transport Group amplify their voices in Westminster, pressing for fairer funding formulas, longer settlement periods, and greater flexibility in how monies are spent. The Campaign for Better Transport and other think tanks regularly highlight mayors' arguments for increased investment. A notable example is the successful lobbying by the Mayor of London for emergency funding settlements during the pandemic, which prevented TfL from collapsing under the weight of lost fare revenue. Without that advocacy — backed by data on London's economic importance — the capital's transport network would have suffered severe cuts. This demonstrates that mayors' political capital is a tangible asset in securing resources.

Key Funding Sources and Mechanisms

Understanding the mosaic of funding streams available to mayors is essential to appreciating both the opportunities and constraints they face. UK urban transport is financed through a mix of central government grants, local taxation, farebox revenue, and innovative mechanisms such as land value capture and public-private partnerships.

Central Government Grants

The largest single source of capital funding for city transport remains central government. Programmes such as the City Region Sustainable Transport Settlements (CRSTS) provide multi-year capital allocations to combined authorities. For example, the second round of CRSTS, covering 2027–2032, aimed to give mayors greater certainty for planning major infrastructure. In addition, specific pots like the Levelling Up Fund and the Transforming Cities Fund have directed billions toward bus improvements, tram extensions, and cycle networks. However, mayors often criticise the short-term nature of these grants and the need to compete in bidding rounds, which can undermine strategic long-term planning. The "winner-takes-all" dynamic, where larger cities like London and Manchester secure disproportionate funding, remains a persistent grievance among smaller city-regions.

Local Funding: Council Tax and Business Rates Supplements

To supplement central government money, mayors have limited powers to raise revenue locally. The Greater London Authority can levy a council tax precept specifically for TfL, while metro mayors can apply a supplement on business rates (up to 2 pence in the pound) to fund transport projects, subject to a local ballot. The West Midlands' use of the business rates supplement to support the Midland Metro tram extension is a case in point. Mayors must carefully balance the need for revenue against the political cost of raising taxes, especially in areas with lower average incomes. Some mayors have called for greater fiscal devolution, including the ability to retain a share of business rates growth or introduce new local taxes such as a payroll levy. Without such powers, mayors remain heavily dependent on Whitehall.

Public-Private Partnerships and Developer Contributions

Leveraging private capital is another tool in the mayor's funding arsenal. Public-private partnerships (PPPs) have financed major projects such as the DLR extension to London City Airport and the Sheffield Supertram. More recently, mayors have used Section 106 agreements and the Community Infrastructure Levy to extract contributions from developers building near new transport links. The concept of "land value capture" — where a portion of the uplift in property values generated by a new station or line is used to fund that infrastructure — has gained traction. Mayors like Andy Burnham and Steve Rotheram have piloted such approaches. However, private finance remains less common for operational subsidies, and the risk of overly optimistic revenue projections has led to caution after the collapse of some PPP deals, such as those for London Underground upgrades. Mayors must therefore carefully structure partnerships to protect public interests.

Challenges Confronting Mayors in Securing Resources

Despite their growing power, mayors face formidable obstacles when trying to secure adequate and sustainable funding for public transport. These challenges stem from structural weaknesses in the UK's fiscal framework, political cycles, and the inherent difficulty of prioritising long-term investment amid short-term pressures.

Revenue vs. Capital Funding

A critical distinction exists between the capital grants used to build infrastructure and the revenue funding needed to operate services. Mayors often find it easier to secure one-off capital sums for new lines or trains but struggle to obtain the ongoing operational support that keeps systems running, especially in the wake of the pandemic's impact on farebox recovery. TfL's long-running dispute with the government over its funding settlement highlighted this tension: the capital's transport network required substantial revenue subsidies to maintain service levels even after receiving billions for upgrades. Many metro mayors argue that the UK's poor performance on bus and rail ridership growth compared to European peers is partly due to a systemic under-investment in revenue support. Without addressing this imbalance, even well-funded capital projects risk being underutilised.

Political Cycles and Long-Term Planning

Major transport investments — such as tram lines, new stations, or electrification — can take a decade or more from concept to completion. Yet mayoral terms last only four years, and central government funding allocations often align with parliamentary cycles. This mismatch creates a "stop-start" pattern of investment, where projects may be cancelled or scaled back after a change of administration. The scrapping of the eastern leg of HS2 and the uncertainty around Northern Powerhouse Rail have demonstrated how fragile political commitments can be. Mayors invest huge political capital to secure funding, but if central government priorities shift, their efforts can unravel. Some mayors advocate for a National Infrastructure Commission with binding multi-year budgets to insulate transport spending from short-term political whims.

Competing Priorities and Fiscal Constraints

Mayors must balance transport with other pressing responsibilities — housing, policing, skills, and economic development. In regions with growing populations and tight budgets, funding a new bus route might mean sacrificing a housing regeneration scheme. The fiscal constraints imposed by central government, such as council tax caps and borrowing limits, further restrict mayors' room for manoeuvre. The pandemic and cost-of-living crisis have exacerbated these trade-offs, as rising inflation pushes up construction costs and fares fall at a slower pace than expected. Many mayors have had to divert resources to subsidise fares or maintain services, reducing the funds available for transformational projects. This zero-sum game makes strategic planning arduous.

Innovative Solutions and Best Practices

To navigate these challenges, mayors across the UK are pioneering innovative funding mechanisms and policy approaches that could serve as models for others. These initiatives often involve a mix of new revenue tools, smarter procurement, and closer integration of land use and transport planning.

Congestion Charging and Clean Air Zones

Congestion charging and clean air zones generate revenue while simultaneously discouraging car use and improving air quality. London's congestion charge, introduced in 2003, has raised billions for TfL and reduced traffic in the city centre. Following London's lead, other cities like Manchester and Birmingham have considered or implemented clean air zones, though often with less aggressive pricing. The challenge for mayors is the political unpopularity of such measures — proposals for a congestion charge in Greater Manchester were overwhelmingly rejected in a 2008 referendum. Nevertheless, mayors are increasingly framing these charges as investments in sustainability rather than taxes. The revenue stream, if ring-fenced for transport, provides a degree of fiscal autonomy independent of central government grants.

Land Value Capture

Land value capture mechanisms are being refined to finance transport infrastructure. The Elizabeth line (Crossrail) in London used a substantial boost from the Mayoral Community Infrastructure Levy on developments along the route. Similarly, the proposed West Yorkshire tram network is being planned with a land value capture component. Mayors are experimenting with "betterment" taxes, where a portion of the increase in property values around new stations is collected to repay borrowing. The Urban Land Institute has estimated that well-designed land value capture could cover up to 20% of major scheme costs in UK cities. However, implementation requires complex valuation and legal frameworks, and mayors must ensure that the burden does not fall disproportionately on existing residents or small businesses.

Devolution Deals and Trailblazer Deals

The "Trailblazer" devolution deals agreed in 2023 between central government and the West Midlands, Greater Manchester, and other regions have provided mayors with greater financial flexibility. These deals gave mayors a single consolidated funding settlement for transport, including a multi-year budget, and additional borrowing powers. The West Midlands' Trailblazer deal, for instance, included a commitment to explore a local brownfield housing and transport fund that allows the mayor to recycle capital receipts. Such deals represent a step towards the kind of integrated, place-based funding that mayors have long called for. However, they are still limited in scope, and many smaller city-regions feel excluded from these flagship arrangements. Expanding the Trailblazer model to all combined authorities could significantly improve mayors' ability to plan long-term.

The Future of Urban Mobility — Mayors Leading the Way

Looking ahead, the role of mayors in securing resources for public transport will only grow in importance. UK cities face the dual pressures of population growth and the net-zero transition, while also recovering from the pandemic's disruption to travel patterns. Mayors who can marshal diverse funding streams, build cross-sector coalitions, and communicate a compelling vision for their city's mobility future will be best placed to deliver the transport systems that residents need and deserve.

Net Zero Targets and Sustainable Transport

The UK's legally binding commitment to reach net-zero greenhouse gas emissions by 2050 — and the interim target of a 78% reduction by 2035 — places transport at the centre of the decarbonisation agenda. Transport is the largest emitting sector, accounting for around 27% of UK emissions. Mayors are responsible for developing local transport plans that shift journeys from private cars to public transport, walking, and cycling. Achieving this requires not only capital investment in electric buses and cycle lanes but also revenue funding to keep fares affordable and increase frequency. Some mayors are exploring "fares-free" or heavily subsidised services for specific groups, such as young people or low-income residents. Securing the funding for these policies often means making a strong economic case: every pound invested in sustainable transport can generate multiple pounds in health, productivity, and environmental benefits.

Integrated Smart Mobility

The future of urban mobility is integrated and digital. Mayors are promoting Mobility-as-a-Service (MaaS) platforms that allow travellers to plan, book, and pay for multimodal journeys through a single app. Such systems rely on investment in data infrastructure and the willingness of different transport operators — buses, trains, bike-share, car clubs — to cooperate. Mayors can use their convening power to encourage integration, but funding is needed to build the technological backbone. The West Midlands' "Swift" smart card and London's Oyster/contactless system are early successes. Future models may incorporate dynamic pricing based on demand and carbon footprint. Mayors who champion these innovations can attract private investment, reduce congestion, and improve the passenger experience.

Social Inclusion and Accessibility

Finally, mayors must ensure that public transport serves all communities, not just affluent city-centre workers. Funding must be directed toward routes in poorer suburbs and rural-urban fringe areas, where car ownership is low but bus services are often thin. The pandemic hit bus ridership hard, and many services remain at risk of cuts. Mayors like Andy Burnham have used devolved bus franchising to introduce capped fares and simplify ticketing, making transport more affordable. But stability requires long-term revenue funding from central government. The upcoming Comprehensive Spending Review will be a critical test of whether mayors' advocacy can secure the resources needed to prevent a "transport poverty" crisis. Additionally, mayors must ensure that new infrastructure is fully accessible for disabled people and older adults, which often requires additional investment beyond basic design standards.

In conclusion, mayors in the UK are increasingly the key figures who can shape the future of urban mobility. Their ability to secure public transportation funding — through advocacy, innovative financing, and strategic use of devolved powers — will determine whether cities become more connected, sustainable, and equitable. While challenges of revenue shortfalls, political instability, and competing priorities remain, the best mayors are already demonstrating that with the right mix of resources and reforms, transformative change is possible. The choices made in the next decade will set the course for generations to come.
