UK Could Lose £230B Without Urgent Mobile Network Upgrades

A report from BT and Assembly Research warns the UK is at a digital crossroads: the choices the country makes about mobile network upgrades over the next decade will determine whether it captures major economic and social benefits or falls further behind global competitors.

If the UK commits to serious investment and policy reform, the report estimates up to £230 billion of economic value could be unlocked by 2035 through smarter industry, improved travel and resilience, and better services for rural communities. If policymakers and industry fail to act, the nation risks missing a significant opportunity to boost productivity and innovation.

Howard Watson, Chief Security and Networks Officer at BT Group, emphasised the changing nature of mobile connectivity and the need for greater private-sector investment supported by government and local stakeholders: “The way we use mobile connectivity is evolving, and as the demands on network capacity increase and retail pricing remains comparatively low, greater support is needed to unlock more private sector investment. To deliver the networks the nation needs for the future, we need greater collaboration with the government and regulator, as well as support from local communities and councils – so that everyone in the UK can reap the life-changing benefits connectivity brings.”

Where did this £230 billion figure come from?

The £230 billion estimate is the combined outcome of several practical gains better mobile technology could deliver by 2035. The report’s breakdown highlights how different sectors would benefit:

  • £124 billion from smarter cities and industries — including factories optimised by AI, widespread drone deliveries, and significant growth in the creative sector driven by advanced connectivity.
  • £57 billion from improved travel — reliable connectivity on rail services would make commutes more productive (around £12 billion), while enabling connected and autonomous vehicles could deliver around £45 billion in value.
  • £45 billion from greater national resilience — a modernised energy grid supported by robust connectivity could reduce the risk of blackouts (roughly £37 billion) and provide business continuity options that limit disruption from internet outages (about £7.9 billion).
  • £3.1 billion for rural communities — enhanced mobile coverage in countryside areas would directly support agriculture, tourism and local services.

Matthew Howett, Founder & CEO of Assembly Research, said the modelling shows how advanced, resilient and widely available mobile coverage supports productivity on journeys, lowers downtime from outages, and helps adoption of emerging technologies. He noted that as the Government pursues its economic growth agenda, targeted investment in mobile connectivity can deliver meaningful benefits across the UK.

Mobile network upgrades for a better-connected UK

BT’s analysis identifies major barriers currently holding the UK back. An outdated planning system slows the rollout of new mobile masts and sites, leaving the country with fewer base stations per capita than many peers and contributing to slower mobile speeds compared with other developed nations.

“The UK is mid-way through a profound digital revolution… but only with the right policy and regulatory interventions,” Watson adds. The report therefore sets out a pragmatic plan for government action to catalyse investment and speed deployment of improved networks.

One recommendation is a new “Mobile Markets Review” to stimulate investment in mobile infrastructure—similar in ambition to the interventions that helped expand full-fibre broadband coverage dramatically in recent years.

Near-term recommendations include practical steps to boost capacity and cut barriers to deployment:

  • Release more spectrum: Doubling or otherwise increasing available radio frequencies for mobile services is presented as a cost-effective way to improve capacity and coverage nationwide.
  • Reduce planning delays: Reforms to planning rules and permitting processes could shorten the lead time for new mobile sites by as much as a year, enabling faster expansion and upgrades.

Watson argues the moment is right for decisive action: with the right policy support and industry collaboration, the next decade could deliver transformational improvements in UK connectivity and unlock the benefits outlined by the report.

If policymakers, operators and communities work together to address spectrum availability, streamline planning and promote investment, the UK could secure faster speeds, greater resilience and widespread benefits for businesses, commuters and rural areas alike—helping the country remain competitive and ready for the next wave of technology-driven change.
