National Grid is building a new network of cable tunnels, 32.5km in length, between Wimbledon and Crayford.
This project is the second phase of the scheme to rewire the Capital, called London Power Tunnels. It follows the success of the first phase, which was a seven-year, £1 billion programme, building 32km of tunnels and two new substations in North London.
The second phase is essential in order to replace existing electricity cables in South London which are coming towards the end of their useful life, the majority of which are buried beneath the road network.
South London Timber are supplying a huge range of construction timber.
