Cornerstone has appointed United Infrastructure as its new national partner to support the planned preventative maintenance and reactive repair of its UK-wide telecoms estate.
From May 2026, the framework will see United Infrastructure become the sole provider of maintenance services across more than 16,000 sites nationwide, including locations in Northern Ireland and the Scottish Highlands and Islands. The estate underpins mobile connectivity for millions of people, businesses and essential public services across urban, rural and hard-to-reach areas, forming a critical part of the UK’s digital and economic infrastructure.
The appointment follows a rigorous and carefully governed selection process, with safety, resilience, quality and long-term assurance at the centre of Cornerstone’s decision-making.
Under the framework, United Infrastructure will work closely with Cornerstone to support the ongoing operation of the estate, with a focus on improving visibility, streamlining reporting and strengthening milestone tracking, while continuing to uphold Cornerstone’s industry-leading standards for health, safety and secure site access.
“Safety, resilience, quality and assurance were central to our decision-making. United Infrastructure demonstrated clear alignment with our safety-first culture and the operational discipline required to maintain the UK’s largest passive infrastructure network, enable 5G rollout and support future connectivity ambitions.
This framework cements a foundational part of our strategy to maintain and enhance the UK’s critical national infrastructure and is central to how we protect our people, our customers, our partners, our landlords and the communities our sites serve, every day”
Andy Train, Chief Network Officer, Cornerstone
“We are extremely proud to have been selected by Cornerstone as their sole partner for this UK-wide maintenance programme. This framework reflects a shared commitment to ensuring the reliability, resilience and future-readiness of the nation’s digital infrastructure.
We look forward to working collaboratively with Cornerstone to enhance the estate through smarter reporting, streamlined delivery and a focus on sustainable, long-term asset performance”
