The UK telecoms sector has received a sharp warning from Kearney’s 2026 Global Telecom Health Index.
The report ranked the UK 33rd out of 34 countries for overall sector health. It measured financial performance, network quality, market structure, commercial strength, and customer satisfaction.
According to the study, the UK placed 28th for customer sentiment. It also fell into the lower half for technology deployment and commercial performance.
The findings arrive during a sensitive period for operators and investors. Network upgrades remain expensive, while revenue growth stays under pressure. Many providers also face rising demand for faster fibre and stronger mobile capacity.
Meanwhile, the report points to a clear market pattern. Countries with three mobile operators or fewer scored better in most categories. The same trend appeared in fixed broadband markets. More concentrated markets showed higher fibre coverage and stronger adoption.
Yet fewer operators do not guarantee better networks. Scale can help companies invest more confidently. However, regulators must still protect pricing, service quality, and customer choice.
Rajiv Datta, CEO of Nexfibre, believes the UK needs a stronger wholesale challenger.
“The UK’s telecoms market is fragmented and fragile. To deliver greater choice and quality for consumers and businesses alike, it requires a scaled financially secure, wholesale challenger. Consolidation will be crucial as the route to sustainable competition and a healthier sector,” he says.
Mobile infrastructure also needs a new focus. Steve Cray, Managing Director of Cellnex UK, argues that coverage alone is no longer enough.
“The UK’s position in these rankings reflects a mobile network architecture and policy environment that has historically prioritised broad geographic coverage, rather than network capacity and user experience,” he explains.
This distinction matters for 4G, 5G, and future mobile services. A signal may exist, but users still need reliable speed and capacity. Busy towns, transport hubs, and business districts often expose network limits.
Cray says leading European markets made stronger policy choices. They set clearer national goals for network quality. They also rewarded investment and gave customers better performance data.
“This has not happened by accident. The most successful markets have combined clear and publicly stated national ambitions for network quality with telecommunications policies and regulatory frameworks that both encourage and reward investment,” he says.
For fixed networks, stability remains equally important. Investors need confidence through the final, costly stages of rollout.
Steve Leighton, Chair of ISPA, highlights regulation and adoption as decisive factors.
“Consistent, proportionate regulation is what will get the UK to nationwide gigabit coverage by 2032.
“The second is take-up. A sustained, coordinated effort on digital inclusion, consumer awareness and a managed migration away from legacy copper is essential to continue converting the investment already made into the huge productivity and growth benefits that gigabit connectivity is capable of,” he concludes.
The message is clear. The UK has ambition, capital, and proven technology. It now needs coordinated execution, stable rules, and networks built for real demand.
