United Infrastructure awarded national maintenance framework by Cornerstone for UK-wide telecoms estate

United Infrastructure, a leading provider of solutions for the UK’s critical infrastructure, is pleased to announce that its Connected business has secured a major new framework with Cornerstone, the UK’s leading digital infrastructure service provider.

United Infrastructure will become the sole provider of planned preventative maintenance and reactive repairs across more than 16,000 telecoms sites nationwide, including Northern Ireland and the Scottish Highlands and Islands. The framework begins in May 2026. The telecoms estate underpins mobile connectivity for millions of people, businesses and essential public services across urban, rural and hard-to-reach areas.

Andy Train, Chief Network Officer at Cornerstone, said:

“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 enhance 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.”

United Infrastructure will work closely with Cornerstone to drive greater operational efficiency, enhancing visibility, streamlining reporting and refining milestone tracking across the network, while upholding Cornerstone’s industry-leading standards for health, safety and secure site access across its telecoms estate.

United Infrastructure has also committed to creating new apprenticeship roles across both field and office-based functions, investing in future generations and developing talent within the telecoms industry.

Scott MacGregor, Managing Director, Connected at United Infrastructure, said:

“We are extremely proud to have been selected by Cornerstone as their sole partner for this UK-wide maintenance programme. This framework reflects the strength of our business and our 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 their network through smarter reporting, streamlined delivery and a focus on sustainable, long-term asset performance.”
