Balfour Beatty wins London Piccadilly line upgrade


Balfour Beatty has been awarded a £43 million contract by Transport for London (TfL) to deliver essential upgrade works on the London Underground’s Piccadilly line. 

It marks the second contract to be awarded to Balfour under the London Underground High Voltage (HV) Power Framework, to which the company was appointed last year.  

Balfour will be responsible for the design, supply and installation of new assets at Hatton Cross and Hounslow substations including transformer rectifiers, high voltage and low voltage switchboards, direct current switchboards and auxiliary transformers, and associated cable routes. 

It will support the increase in traction power needed for the next generation of Piccadilly line trains and to deliver increased capacity along the route.  

Works are due to commence by the end of the year, with completion expected in 2026.  

At peak construction the company will employ approximately 40 people, with 5 per cent of its workforce made up of apprentices and graduates as part of its commitment to The 5% Club. 

“This latest contract award is testament to our long-standing relationship with Transport for London, having worked collaboratively with them for the last 20 years,” said Mick Rayner, managing director of Balfour Beatty’s Rail business. 

“We look forward to further supporting the upgrade and enhancement of the Piccadilly line helping to provide a smooth and reliable service for the travelling public across the city.”
