London Power Tunnels 2

Reference design for six new head houses in the second phase of this ambitious project to ‘rewire London’


This new project follows our success in the original London Power Tunnels project (LPT1), a seven year £1 billion scheme to rewire the Capital.

Fereday Pollard, working with WSP, are developing the reference design for six new head houses serving the 32.5km eastern section of the proposed cable tunnel route from Wimbledon to Crayford. The head house designs share a common design language which will provide a modern functional appearance and respond to the different site conditions.

The works are essential in order to replace existing electricity circuits which are coming towards the end of their useful life. The majority of these currently run beneath the road network.

The new cable tunnels are part of National Grid’s £750 million investment to ensure a continued safe and secure supply of electricity to the Capital.

In London, most electricity is transmitted through underground cables. These are traditionally located just beneath the road surface and work to maintain them is usually carried out in the road.
