UK mayors have emerged as pivotal figures in shaping the economic trajectories of their cities and regions. Their influence, far from being merely ceremonial, now directly impacts investment flows, infrastructure priorities, and the vitality of local business ecosystems. This expanded role stems from successive waves of devolution that have transferred meaningful powers from Whitehall to city-region mayors, enabling them to craft bespoke growth strategies tailored to local strengths and challenges. Understanding how these mayors influence economic development is essential for policymakers, business leaders, and investors navigating the UK's evolving governance landscape.

The Evolution of Mayoral Powers in the UK

The modern era of powerful metro mayors began in 2014 with the introduction of directly elected city-region mayors in Greater Manchester, Liverpool City Region, and the West Midlands. These positions were created alongside combined authorities—collaborative bodies formed by multiple local councils—to provide a single accountable leader with a strategic remit for economic development, transport, housing, and skills. Subsequent devolution deals have expanded these powers, giving mayors control over adult education budgets, local transport networks, housing investment funds, and planning for strategic sites. As of 2025, there are twelve directly elected metro mayors in England, with proposals for further expansion in counties like Cornwall and the North East. The Institute for Government provides a comprehensive overview of their current powers and responsibilities.

Devolution Deals and Fiscal Levers

Each devolution deal is bespoke, negotiated between central government and the combined authority. Common elements include consolidated transport budgets, control over a local skills fund, and the ability to retain growth in business rates collected within the region. A few mayors, like those in Greater Manchester and the West Midlands, have gained additional fiscal levers such as the right to pilot a tourist levy or to set business rate supplements for major infrastructure projects. These financial tools enable mayors to act decisively—investing in catalytic projects without waiting for Whitehall approval.

Key Levers for Economic Growth

UK mayors influence local economic growth through a portfolio of powers that span five critical domains: infrastructure, skills, housing, business support, and inward investment. Each lever interacts with the others, creating a coherent strategy that aims to boost productivity, raise employment levels, and close regional disparities.

Infrastructure and Transport

Improved connectivity is widely recognized as a catalyst for economic growth. Mayors oversee local transport networks, including buses, trams, and rail services. They can integrate ticketing, invest in new routes, and prioritise projects that unlock development sites. For example, the West Midlands Metro expansion has been a signature initiative of Mayor Andy Street, linking city centres with employment zones. Similarly, the Liverpool City Region Mayor Steve Rotheram has championed a London-style integrated transport system. These investments reduce commuting times, widen labour markets, and make regions more attractive to businesses considering relocation.

Infrastructure extends beyond transport to include digital connectivity and energy. Several mayors have established regional digital infrastructure strategies to rollout full-fibre broadband and 5G, particularly in underserved areas. Such improvements lower operating costs for firms and enable new business models in logistics, tech, and advanced manufacturing.

Skills and Employment

Devolution of the adult education budget (AEB) gives mayors direct control over how funds are spent on training and skills programmes. They can align provision with local economic priorities—for example, funding digital bootcamps in tech hubs or advanced manufacturing apprenticeships in industrial clusters. The Greater Manchester Combined Authority has pioneered the Working Well programme, a bespoke employability and health support initiative that has helped thousands of long-term unemployed residents into work. By tailoring skills systems to employer demand, mayors help close the local skills gap, reduce unemployment, and increase productivity.

Mayors also influence careers advice and school-to-work transitions. Many have established careers hubs and employer engagement programmes that bring businesses into schools, ensuring young people are aware of local opportunities in growth sectors. These interventions build a pipeline of talent that makes the region more competitive for inward investment.

Housing and Regeneration

Housing affordability and availability are critical for attracting and retaining a skilled workforce. Mayors set strategic housing targets, allocate investment from central government housing funds, and can create local development corporations to accelerate regeneration. The West Midlands Combined Authority, under Mayor Street, has committed to building over 200,000 new homes by 2031, with a focus on brownfield sites to protect greenbelt land. Similarly, the Mayor of London sets the London Plan, the statutory spatial development strategy that guides housing delivery and infrastructure across the capital. By addressing housing constraints, mayors create a more attractive environment for businesses and workers, directly supporting economic growth.

Business Support and Innovation

Direct support to local businesses is another key lever. Mayors administer business grants and loan programmes, often targeting specific sectors like low-carbon innovation or advanced manufacturing. They also foster clusters of innovation by investing in research centres, accelerators, and university partnerships. The Liverpool City Region Mayor Steve Rotheram launched a £5 million Innovation Fund to support spin-outs and start-ups in life sciences, while the Greater Manchester Mayor Andy Burnham has championed the region's digital and creative sectors through the Manchester Digital strategy. These targeted investments help diversify local economies and build resilience against future shocks.

Simplification of regulation also falls under mayoral influence. Several combined authorities have introduced streamlined planning approval processes for major developments, cutting time-to-build for new factories or data centres. Mayors can designate investment zones where businesses benefit from simplified tax regimes and planning freedoms—a tool that the West Midlands and Liverpool City Region have actively used to attract high-tech manufacturing and logistics firms.

Inward Investment and Trade

Mayors act as chief salespeople for their regions on the global stage. They lead trade missions to high-growth markets such as the United States, China, and the Middle East, showcasing local strengths in sectors like clean energy, fintech, and life sciences. The Mayor of London's International Business Programme has supported over 2,000 small firms to export. Regional mayors collaborate with the Department for Business and Trade to target specific investors, offering tailored inward investment packages that include site visits, market intelligence, and access to talent pipelines. Research from the Centre for Cities shows that mayoral engagement can significantly shorten decision times for foreign investors, who value having a single accountable point of contact.

Case Studies: How Mayors Drive Growth

Examining specific mayors reveals how these levers translate into tangible outcomes. Each has adopted distinct approaches shaped by their regional economic base and political context.

Greater Manchester – Andy Burnham

Mayor Andy Burnham has focused on social inclusion alongside growth. His flagship initiatives include the Greater Manchester Good Employment Charter, which encourages employers to offer secure work, fair pay, and training opportunities. The charter has been adopted by over 100 businesses, covering more than 200,000 employees. Burnham has also prioritised investment in public transport, with the ongoing expansion of the Metrolink network to serve Salford Quays and the Trafford Centre, linking employment zones. His administration's work on skills, through the Local Skills Improvement Plan, has aligned post-16 provision with the needs of health, digital, and advanced manufacturing sectors. Economic data shows the Greater Manchester economy grew by 8% between 2017 and 2023, above the UK average for combined authorities, with strong performance in digital and creative industries.

West Midlands – Andy Street

Andy Street, a former John Lewis managing director, has brought a corporate-style focus to mayoral leadership. He established the West Midlands Growth Company, an investment agency that has secured over £2 billion of inward capital since 2017. The region has attracted major projects such as Jaguar Land Rover's electric vehicle battery plant at the Coventry Gigafactory, and HS2's Interchange Station, which will open in 2026. Street's housing strategy, including the Brownfield Land Programme, has released over 4,000 homes on previously developed sites. His administration has also championed the Commonwealth Games legacy, using the 2022 event to accelerate regeneration of the Perry Barr area. The West Midlands has recorded the highest foreign direct investment (FDI) project count of any English region outside London since 2018, per WMCA data.

London – Sadiq Khan

While the Mayor of London's powers differ—covering policing, transport, planning, and economic development—Sadiq Khan's approach illustrates the importance of strategic vision. His London Plan sets a target of 66,000 new homes per year and prioritises a compact city model with development focused on transport hubs and brownfield sites. Khan has invested over £100 million in digital inclusion and skills programmes, including the London Digital Jobs and Skills Programme. His Good Work Standard encourages employers to pay the London Living Wage, provide training, and ensure workplace well-being. London's economy, valued at over £500 billion, remains the UK's primary engine, and mayoral leadership has been credited with maintaining the capital's global competitiveness post-Brexit, particularly in financial services and technology. The GLA's economic development pages detail these initiatives.

Challenges and Limitations

Despite their growing influence, UK mayors face significant constraints. Funding remains a persistent issue: metro mayors control only a fraction of the total public spending in their regions. The majority of budgets are still allocated by central government departments, limiting mayoral ability to respond to crises or strategic opportunities. For example, during the 2020 pandemic, mayors had to rely on Whitehall for emergency business support, frustrating local adaptiveness.

Political tensions can also hinder progress. Mayors must negotiate with multiple councils within their combined authority, each with its own political composition and priorities. While the mayor holds a mandate, they cannot simply override local authorities on sensitive issues like greenbelt release or local tax increases. The result can be slow decision-making or watered-down strategies.

Another limitation is the uneven distribution of devolved powers. Some mayors control housing investment funds and skills budgets, while others have limited financial autonomy. The government's Levelling Up White Paper promised a "trailblazer devolution" programme offering deeper fiscal devolution, but implementation has been gradual. Without a more consistent and ambitious devolution settlement, the potential of mayoral leadership may remain only partially realised.

The Future of Mayoral Leadership in Economic Growth

Looking ahead, the role of UK mayors in driving local economies is likely to expand. The government has signalled its intention to devolve further powers, including integrated settlements for health, housing, and employment support. Proposals for mayors to gain control over police and fire services, as well as part of the apprenticeship levy, are under discussion. Several counties are seeking to establish mayoral combined authorities—including Buckinghamshire, Cornwall, and the North East, which elected its first metro mayor in 2024.

Mayors are also becoming central to delivery of net zero ambitions. Many have declared climate emergencies and set ambitious targets: Greater Manchester aims for carbon neutrality by 2038; the West Midlands by 2041. To achieve these goals, mayors are investing in retrofitting housing, expanding renewable energy generation, and promoting green public transport. These investments not only reduce emissions but also create local jobs in construction, engineering, and clean tech, demonstrating the mutual reinforcement of economic and environmental objectives.

Technology will further enhance mayoral impact. Digital twins—virtual replicas of physical regions—are being developed in Greater Manchester and the West Midlands to model the effects of planning decisions, transport changes, and climate policies. These tools enable evidence-based policymaking and better engagement with businesses and citizens. As data capabilities improve, mayors will be able to tailor economic interventions more precisely, from targeting business support to predicting skills shortages.

Conclusion

UK mayors have transformed from symbolic figures into powerful agents of local economic development. Through strategic control over transport, skills, housing, and business support, they attract investment, foster innovation, and address deep-rooted regional inequalities. Their leadership is not without challenges—funding constraints, political complexity, and inconsistent devolution hold back full potential. Yet the evidence from Greater Manchester, the West Midlands, and London shows that proactive, accountable mayors can deliver tangible economic benefits: higher employment, increased FDI, better infrastructure, and more resilient local economies. As the UK navigates post-Brexit trading relationships, accelerates net zero, and seeks to level up left-behind areas, the mayoral model is likely to become even more central. For businesses, understanding and engaging with these mayoral strategies is increasingly essential for navigating the opportunities and risks within the UK's city-regions.
