Over the past decade, the UK telecoms landscape has undergone significant transformation. To understand the implications of these changes, particularly for landowners, we spoke with Henry Mawhood, Senior Surveyor in the Telecoms team.
The market has shifted from a competitive field of multiple mobile operators with the list sat at 431 code operators today however, the largest mobile roaming networks are now dominated by just three major players:
- BT Group acquired EE in 2016, bringing fixed-line and mobile services under one umbrella to expand consumer offerings
- In 2021, Virgin Media and O2 merged to form VMO2, combining broadband, TV, and mobile services.
- Most recently, in May 2025, Vodafone and Three completed their merger, creating VodafoneThree, with a £11 billion investment plan to build one of Europe’s most advanced 5G networks over the next decade and share infrastructure and services
These mergers are more than just corporate milestones, they are reshaping the UK’s digital infrastructure and creating new dynamics for landowners hosting telecoms equipment.
Key Impacts for Landowners
As the networks consolidate and infrastructure is streamlined, several trends are emerging:
- Site consolidation: Operators are reviewing and merging mast portfolios, which may lead to decommissioning or renegotiation of existing agreements.
- Increased infrastructure demand: The rollout of 5G and fibre networks is accelerating, with a focus on shared infrastructure and rural connectivity.
- More complex negotiations: With fewer, but larger and more integrated operators, lease agreements and site access arrangements are becoming more nuanced.
Navigating a Changing Market
For landowners, these changes can bring both uncertainty and opportunity. Understanding who now controls a site, what their strategic goals are, and how a property fits into evolving network plans is essential.
Henry said: “We are supporting landowners through this transition, reviewing lease terms, advising on the implications of network consolidation, and helping to manage new infrastructure proposals.
“The telecoms market may be consolidating, but the need for clear, informed advice has never been greater. Landowners need to be aware of how these changes affect their agreements and their rights.”
