National Grid: London
Power Tunnels 2 –
Rewiring London

A National Grid seven year, £1 billion project, to rewire South London via deep underground
tunnels.

In total, 32.5km of 3m diameter tunnels are being constructed deep below the road network between Wimbledon and Crayford, which will carry high voltage electricity cables.

How we helped

This work included engagement, consultation, and land acquisition advice which included the purchase of a critical TBM site on Kings Avenue in Southwest London. This secured the critical construction site along the whole tunnel route which de-risked programme delay and reduced cost pressure significantly.

Our further work included formal valuations of land around existing substations in Wimbledon, the assessment of
public open space land in Crayford, and the release of restrictive covenants (and the valuation of such) on other statutory undertaker’s land.

Further, we secured a leasing agreement with option to acquire permanent land post project completion at the UKPN substation site in Eltham.

Services provided:

• Valuation
• Grantor liaison
• Negotiation of land both leasing land and permanent acquisition
• Valuation of land.

The outcome

Our compulsory purchase team supported the National Grid project team on site identification, land assembly strategy, mitigation and site acquisition pre-Compulsory Purchase Orders a key step on the journey of this large London infrastructure project.
