Works to be carried out include the renewal and replacement of old assets such as High Voltage and Low Voltage Switchboards along with new HV Cables at many substations across the Piccadilly line including Hyde Park Corner, Cockfosters, Sudbury Hill, Northfields, and Leicester Square.

Balfour Beatty’s Rail & Utilities business managing director Matthew Steele said: “This latest contract award is a significant achievement, building on our 19-year relationship with London Underground. It is testament to our unrivalled capability and deep domain knowledge in delivering underground rail works.”

“Once complete, the programme will transform travel for thousands of passengers each day and ensure that the London Underground can continue to run a reliable and safe service for many more years to come.”

Upgrade works will commence this month, with completion anticipated in 2025.

During the construction peak, Balfour Beatty will employ around 80 people.
