Ofcom’s Connected Nations 2025: Rising Data Demand and the UK’s Rapid Shift to 5G Standalone

Ofcom has released its 2025 Connected Nations UK Report, confirming rising mobile data demand and rapid expansion of 5G standalone networks. The annual report provides objective market data on UK telecoms for operators, vendors and investors. This year’s findings show a market transition towards higher-capacity networks, increased spectrum utilisation and early adoption of 5G standalone, alongside behavioural shifts such as landline abandonment and strong satellite broadband take-up in rural areas.

Regulatory background

Under sections 134A-134B of the Communications Act 2003, Ofcom must regularly assess the availability, performance and resilience of fixed and mobile networks. Connected Nations fulfils this statutory duty. The report serves as a key evidence base for regulatory decisions on spectrum management, numbering, security obligations and market interventions.

The companion news update (Brits devour data at record levels as mobile networks race to improve 5G) draws out headline trends on data usage and network deployment. These publications inform Ofcom’s approach to infrastructure policy, universal service, resilience requirements under the Telecommunications (Security) Act 2021, and long-term spectrum planning under the Wireless Telegraphy Act 2006.

Analysis: mobile data and 5G standalone

The report confirms sustained growth in mobile data consumption. UK users now consume more than 1.2 billion GB of mobile data each month, an 18% annual rise. 5G traffic grew 53% year-on-year. Much of this growth stems from increased availability of advanced radio networks and continued use of mobile networks for fixed wireless access. 4G remains the principal bearer, but 5G is rapidly increasing its share, particularly where standalone deployments have intensified.

The standout development is 5G standalone (5G SA). Ofcom has for the first time provided separate coverage data for standalone deployments. At the high-confidence threshold, 83% of the UK now has 5G SA access from at least one operator. Combined 5G coverage (SA and non-SA) reaches 94-97% on Ofcom’s high-confidence measure. This places the UK among the most advanced markets globally in the transition from non-standalone to full 5G.

Fixed networks show similar rollout pace but slower adoption growth. Full-fibre coverage has reached 78% of premises, with gigabit-capable networks available to 87% of homes and businesses. Yet only 42% of premises with fibre access subscribe to the service, and only 21% of those subscribers take a package at or above 900 Mbit/s. The gap between availability and adoption remains a structural feature of the UK broadband market and will inform future discussions on wholesale pricing, retail competition and consumer switching incentives.

The report also highlights behavioural and technological shifts. Over one million households have stopped using a landline, accelerating the move away from PSTN-based services as the industry progresses towards the 2025-2027 digital voice transition. Satellite connections, particularly Starlink, have grown sharply: over 110,000 active UK users, 12,000 of which are in areas lacking decent broadband. This reinforces satellite’s role as a complementary access technology but raises longer-term questions around regulatory treatment, quality of service and consumer protection in non-terrestrial networks.

Commercial and operational implications

For mobile operators, the data shows continued investment in 5G SA and the enabling layer of transport, backhaul and core network upgrades. The increasing share of 5G traffic will require further optimisation of spectrum assets and may accelerate negotiations on spectrum sharing, neutral host arrangements and Open RAN deployments. Operators serving enterprise and IoT markets should note Ofcom’s focus on SA-specific capabilities such as network slicing and low-latency services.

Fixed network operators and alternative networks face a different challenge: converting high fibre availability into higher adoption and higher-tier package take-up. Customer migration strategies, gigabit service differentiation and consistent quality of service performance are the levers. Wholesale-only providers may need to review how they work with ISPs to improve customer understanding of speed profiles and contract structures.

Satellite and FWA providers can view the data as validation of their role in rural and remote premises. For infrastructure investors, the relative maturity of the UK fibre market, combined with early 5G SA scale-up, signals a market moving from build-out to optimisation and consolidation. Those advising on UK-facing M&A transactions will find Connected Nations a reliable data reference point.

Viewpoint

This year’s data confirms that the UK is entering a new phase of connectivity maturity. Rapid 5G standalone adoption, combined with very high gigabit availability, marks a market where the focus shifts from rollout to performance, resilience and long-term commercial sustainability. Operators, vendors and investors can treat these findings as evidence of a structurally stable, high-demand environment in which capacity, spectrum efficiency and customer migration strategies will define competitive advantage.

For regulated providers, this data is also an early indicator of where Ofcom’s future focus will lie: ensuring that network availability translates into meaningful choice, reliability and quality of experience for end-users.
