UK Power Networks Services Partners with TfL for London Underground Upgrade

The project, which is scheduled to finish in June 2025, will see UK Power Networks Services complete the design and construction works to upgrade several key electrical substations, and the installation of new electrical infrastructure, electrical control systems, and cables along key parts of the line. The initial framework contract runs for six years, with potential for two more.

This will allow Transport for London (TfL) to launch a new fleet of air-conditioned modern trains with improved reliability, efficiency, and accessibility for passengers. Overall, the line upgrade will allow for a 23 percent uplift in peak capacity, with a train running on the line every 135 seconds at the busiest times from 2027.

Philip Heathcote, Head of Markets at UK Power Networks Services, said: “We’re at our best when we partner with clients to make their long-term objectives a reality. Our teams are excited to bring their unique expertise to this long-term collaboration and add value though innovation, dedication, and a shared vision to make the London Underground more reliable for the future.”
