The UK is already lagging behind Europe in 5G availability. Now, with landowners threatening to walk away from mast hosting, the problem of mobile blackspots is set to get worse — just as legacy networks like 2G and 3G are being switched off. While technology like RazorLink can bridge connectivity gaps, eliminating not-spots must remain the national priority if the UK is to future-proof its digital infrastructure.

A Crisis for UK Mast Hosts

In August 2025, a national survey by AP Wireless revealed a stark warning: more than a third of mobile mast hosts are considering pulling out. Farmers, schools, charities, councils, churches, and even NHS trusts have all reported severe rent cuts, legal threats, and mounting costs as a result of government rent-slashing reforms under the Electronic Communications Code (ECC).

For many site providers, hosting telecoms infrastructure is becoming financially unviable. Four in five have faced rent reductions of over 80–90%. A third say they face additional costs. And 68% of landlords with expired leases report being pressured or even threatened with legal action.

The result? Around 35% of current mast hosts are “actively” considering withdrawing support. This isn’t just a property dispute — it’s a direct threat to the UK’s mobile coverage at the very moment when connectivity has never been more critical.

The National Farmers’ Union (NFU), Country Land and Business Association (CLA), and British Property Federation (BPF) — all stakeholders in this debate — have sounded the alarm. They represent precisely the groups who will feel the first and hardest impacts of deepening mobile blackspots: rural communities, landowners, and property managers.

UK Already Underperforming on 5G

This mast host crisis lands on top of an uncomfortable truth: the UK is already among the worst-performing countries in Northern Europe for 5G availability. According to research from Ookla, the UK ranks 24th out of 30 nations, with availability at just 45%.

Unlike previous generations of mobile technology, 5G requires a dense web of masts to deliver fast, low-latency coverage. Where 4G could rely on wider-spaced towers, 5G’s higher frequencies mean shorter range, more masts, and greater vulnerability to gaps in the network.

If mast numbers fall, coverage falls with them. Every withdrawal by a landowner risks creating new not-spots that can cut off farms, businesses, hospitals, and schools from reliable digital services.

The 6G Horizon: 10× More Masts Needed

While 5G rollout is still incomplete, industry attention is already turning to 6G. Yet the technical demands of 6G only underline the severity of the current problem.

6G is expected to operate at much higher frequencies — up to the terahertz range — where signals attenuate quickly and are easily blocked by buildings, trees, and even weather. To maintain coverage, far more base stations will be required.

Independent estimates suggest the UK will need around ten times more 6G masts than 5G masts to deliver comparable nationwide coverage. That’s because:

• Higher frequencies mean smaller coverage areas per mast.
• Connection density must increase up to tenfold to support IoT, autonomous vehicles, and advanced mobile applications.
• Speeds and latency (targeting 100× faster performance than 5G and latency in microseconds) require dense, ultra-low-delay networks.

Mast Densification by Generation

Legacy Networks: Safety Net Removed

Until now, mobile blackspots have sometimes been cushioned by legacy networks. If 4G or 5G wasn’t available, users could still fall back on 3G or even 2G. But this safety net is disappearing.

• 3G networks will be fully shut down in the UK by the end of 2025.
• 2G networks are set for nationwide shutdown by 2033, with many operators introducing key retirement milestones as early as 2025 and 2028.

That means in less than a decade, fallback options will vanish. Any gap in mast coverage will result in outright loss of service — no bars, no calls, no data.

For industries reliant on IoT devices, connected machinery, or critical communication systems, that’s not just an inconvenience. It’s a risk to productivity, safety, and competitiveness.

Eliminating Not-Spots: The First Priority

Given this context, one thing is clear: eliminating not-spots must be the UK’s first priority.

Building out mast infrastructure, securing long-term host agreements, and ensuring fair compensation for landowners should come before chasing 6G hype. A fractured 5G footprint undermines national competitiveness, rural growth, and digital inclusion.

Without a dense and resilient mast network, the UK risks becoming stuck in a cycle of underperformance, where each new generation of mobile technology exposes existing weaknesses rather than solving them.

Bridging the Gaps with RazorLink

At Livewire, we believe in a two-track approach. First: fix the fundamentals — secure mast coverage and eliminate not-spots. But second: provide smart connectivity solutions that keep businesses connected even when the mast network falters.

That’s where RazorLink comes in.

RazorLink is Livewire’s core SD-WAN technology, designed to optimise performance, reliability, and security across multiple connections — whether fibre, 4G/5G, or satellite. It mitigates problems like bufferbloat, jitter, and packet loss, delivering enterprise-grade connectivity even in constrained environments.

For sectors such as farming, rural estates, and property management — represented by NFU, CLA, and BPF — RazorLink helps ensure:

• Resilient connectivity in areas where mast coverage is unreliable.
• Seamless failover across different network types.
• Continuity for digital services, from precision agriculture to rural business operations.

This is not about replacing mast infrastructure. It’s about ensuring organisations can stay online in the face of gaps, outages, or underperformance — whether caused by mast withdrawal, weather, or operator disputes.

Connectivity Is Critical Infrastructure

The bigger picture is that mobile connectivity is no longer optional. It underpins education, healthcare, farming, logistics, property, and public safety. When mast hosts are schools, hospitals, or farms, their withdrawal is not just a commercial issue. It is a national infrastructure issue.

As BPF Director of Policy Ion Fletcher noted, “There is a need for a much more collaborative approach from mast operators.” If the UK continues to rely on adversarial relationships with landowners while pushing ahead with rent-cutting reforms, it risks hollowing out the very infrastructure on which 5G — and eventually 6G — depend.

Conclusion: From 5G Struggles to 6G Success

The UK faces a stark choice. Either it reforms its approach to mast infrastructure — working with landowners, paying fair rents, and securing long-term host partnerships — or it risks falling further behind Europe in mobile availability.

At the same time, businesses and organisations cannot wait for policy solutions alone. They need connectivity they can trust today. That means embracing technologies like RazorLink to bridge the gap, eliminate downtime, and provide continuity where traditional infrastructure is unreliable.

Eliminating not-spots must come first. But bridging them with smart solutions is how businesses will thrive in the meantime.
