More than four in 10 people in the UK struggle to access 4G or 5G on their mobile devices for at least half the time they are on the move, according to a survey that lays bare the patchy state of the country’s digital infrastructure. The poll of more than 2,000 digital device users, commissioned by property consultancy Cluttons from Survation, found that 45% felt frustrated with mobile connectivity outside the home at least once a week. Among 18- to 24-year-olds, that figure rose to 57%.
Connectivity problems were less common at home, but more than a quarter (27%) of respondents said they were frustrated with their wifi connection at least once a week. The scale of the issue is also felt by politicians: a separate YouGov poll of 103 MPs found that 21% were contacted at least once a week by residents struggling with slow or variable broadband connections. Nearly 90% of MPs believe good digital connectivity is crucial for increasing productivity and economic growth, according to the same poll.
Global rankings in freefall
The survey comes after a steep decline in the UK’s position in a global league table of mobile download speeds. Last year the UK slipped to 59th place, down from 53rd in 2024 and 51st in 2023. For fixed-line download speeds, the UK is ranked 44th in the world. The data, analysed by ISPreview UK using Ookla figures, paints a picture of a country falling behind peers on the very connectivity that underpins modern life.
Some elements of the network measure up well against European neighbours. The proportion of premises that can access full-fibre and gigabit-capable broadband stands at 86% in the UK, which compares with 80% in Germany, 73% in Italy and 86% in France; Spain leads at 100%. But critics argue the network has been rolled out predominantly in areas that are easier to access and therefore more profitable. “Digital connectivity is fundamental to the UK’s economic growth, acting as the backbone of a modern, productive economy,” said Helen Morgan, the Liberal Democrat MP who chairs the digital communities all-party parliamentary group.
Why the UK is losing ground on mobile speeds
The reasons behind the UK’s declining global mobile ranking are complex, rooted in geography, economics and infrastructure choices. Rolling hills, dense woodland and coastal cliffs make laying fibre-optic cables challenging and costly, particularly in rural areas. Many rural communities still rely on outdated copper networks never designed for modern data demands. Lower population density also makes it less economically viable for traditional internet providers to invest in sparsely populated communities; building infrastructure is expensive and the return on investment can be low.
The disparity between urban and rural coverage is stark. While 86% of UK premises can access full-fibre and gigabit-capable broadband, that figure masks deep regional divides. In England, 88% of urban premises have gigabit-capable broadband, compared with only 54% of rural premises. Ofcom data from January 2026 indicates that 39,000 premises still lack decent broadband from fixed or fixed wireless access networks, though satellite services are helping to reduce that number.
Even where coverage exists, real-world experience can contradict official data. The Shared Rural Network – a 2020 agreement between the government and mobile operators to fill “partial not-spots” by building shared masts – has made progress: Ofcom data from July 2025 showed 96% of the UK landmass had 4G coverage from at least one operator, with 81% having coverage from all operators. Yet practical experience on the ground, as the Cluttons survey suggests, often falls short. Some city-centre broadband speeds are among the slowest in the UK because of the congestion of utilities, while in rural areas the longer distances between homes carry extra installation costs.
Successive governments have urged telecoms providers to accelerate the rollout of superfast broadband and mobile connectivity. The government’s Project Gigabit is investing £5 billion to bring gigabit-capable broadband to remote areas. Morgan’s digital communities APPG has launched an inquiry into “shoddy” rural phone signal, questioning industry leaders. She has previously called for “Rural Roaming” to allow users to switch networks in blackspot areas and proposed legislation making it a legal requirement for firms to cooperate in providing signal.
On the mobile front, 5G standalone coverage has reached 83% of the UK population from at least one operator by January 2026, according to Ofcom, though outside premises coverage ranges between 49% and 85% across mobile network operators. 4G coverage remains stable, with 84% of the UK landmass predicted to have good 4G geographic coverage from all operators by January 2026. Mobile data usage rose 18% year-on-year by November 2025, intensifying pressure on existing networks.
The economic cost of poor connectivity
The survey findings expose a gap between the UK’s digital ambitions and delivery, according to Cluttons. Economic modelling based on the data by Assembly Research found that increasing mobile coverage along railways to 80% from the current 50% average could unlock nearly £3 billion in productivity gains over the next decade, adding more than 66 million hours of passenger productivity by 2035.
“Poor connectivity constrains productivity and competitiveness,” Morgan said. “This is particularly serious in rural areas, where businesses report lost income, operational delays and reduced efficiency. The rollout of digital infrastructure is therefore critical. Investment in full fibre and mobile networks is not just about faster speeds but enabling wider economic transformation.”
Last week, the government announced a £57 million initiative to upgrade Wi-Fi on more than 1,400 trains across the UK using low-earth orbit satellite technology. Ministers said this would provide faster and more reliable service than the mobile networks currently powering onboard Wi-Fi, aiming to boost connectivity from the current 50-60% of train journeys to around 90%. Trials have already begun with companies including Great Western Railway. The digital divide between urban and rural areas continues to affect quality of life, business operations, healthcare and education – a gap that the latest survey suggests is far from closed.
