PwC puts London growth prize at £76bn

PwC has estimated that stronger productivity growth across London’s frontier industries could unlock up to £76bn in additional annual gross value added across the UK by 2030.

The professional services group’s Grow London report argues that productivity growth in finance, technology, and science and research could add between £20bn and £40bn to London’s annual economic output by 2030. Across the UK, the potential uplift rises to between £38bn and £76bn once national supply chains, talent movement, innovation, capital markets, services exports, and fiscal effects are included.

PwC said London provides the conditions for frontier industries to succeed, including talent, capital, universities, investors, and a dense institutional ecosystem. The report highlights the role of AI and fintech in London venture capital activity, noting that they have accounted for 60% of VC deals in the capital since 2019.

Finance, technology, and science and research are identified as the key frontier sectors. PwC estimates that London’s potential uplift could include up to £28bn from finance, £12bn from technology, and £1bn from science and research, with figures reported in 2025 prices.

The report also stresses that the benefit would not be contained within the capital. London acts as a buyer through national supply chains, a talent escalator for regional economies, an innovation and R&D anchoring hub, a foreign direct investment entry point, a capital markets centre, and a professional services base with national reach.

Productivity remains one of the UK’s most persistent economic weaknesses. Growth policy has increasingly concentrated on frontier sectors, AI adoption, scale-up finance, advanced research, and private capital mobilisation. The same pattern is visible in ministers’ attempt to connect AI adoption with workforce skills: technology only raises output when companies change how work, capital, and capability are organised.

PwC’s recommendations focus on management, skills, and operating conditions rather than headline sector promotion alone. The report calls for more investment in leadership development, more frequent training, purposeful AI adoption, cross-industry talent networks, partnerships around data and infrastructure, support for business retention, energy-cost action, and workable housing solutions.

Those recommendations point to the constraints behind the £76bn figure. London has deep strengths, but scale-up growth can still be slowed by housing costs, infrastructure limits, energy costs, regulatory friction, late-stage capital gaps, and competition from other global hubs. Talent concentration helps innovation, but it also raises costs and can make recruitment harder for companies outside the capital.

The national framing is politically and economically sensitive. London’s economic concentration can create tension where regional growth is presented as a counterweight to the capital. PwC’s argument is that London’s frontier sectors create spillovers through supply chains, investment, exports, fiscal contribution, and talent flows. The strength of those flows will determine whether growth reinforces national productivity or deepens geographic concentration.

Company-level productivity discipline will shape how much of the potential uplift is realised. AI tools, data systems, research partnerships, and financial infrastructure can raise output, but the gain depends on management capability. Organisations need to identify where technology changes workflows, which skills are required, how middle managers are developed, and how investment is measured.

The leadership challenge is becoming sharper as AI reshapes junior work. PwC notes that as AI replaces some junior tasks, mid-level employees may lose natural opportunities to develop leadership and people-management skills. Unless development programmes are redesigned deliberately, companies could create a capability gap just as they seek to scale more complex technology-led operations.

The £76bn figure is best read as a prize attached to execution. London’s frontier industries have the conditions to lift UK output, but the gains depend on companies and public institutions converting concentration into productivity rather than simply adding more activity to an already expensive market.
