Where we are working

The main work sites are at:

  • Battersea Power Station
  • Kennington Green
  • Kennington Park
  • Nine Elms adjacent to Wandsworth Road and Pascal Street

In November 2017, main tunnelling finished after the creation of two tunnels between Battersea and new shafts at Kennington Green and Kennington Park.

Preparation works started at these sites in spring 2015. The joint venture Ferrovial Agroman Laing O'Rouke is designing and building the NLE.

Documents related to the project, including those in support of our Transport & Works Act Order (TWAO) application, noise monitoring reports and all but the most recent community communications, are on the Northern line extension page in Publications & reports.

Benefits of the NLE

The Northern line extension (NLE) will improve transport links and public spaces in the area and is essential to support the transformation of Vauxhall, Nine Elms and Battersea, a designated regeneration area on the South Bank.

Up to 25,000 jobs and 20,000 new homes could be created. Journey times from Nine Elms or Battersea to the West End or the City will, in some cases, be less than 15 minutes.

An independent report on the economic impact of the NLE has shown it could generate substantial benefits to the area.

The extension is supported by the Mayor of London and Wandsworth, Lambeth and Southwark councils.

Kennington Green head house and landscaping

In spring 2017, we ran a four week non-statutory consultation on detailed designs for the head house and landscaping scheme at Kennington Green.

This scheme will create ventilation and emergency access for the extended Northern line. We will landscape the Green after the extension work has finished.

The consultation report details the background to the scheme, the feedback we received, our responses and the updated designs for the head house and landscaping.

More information is on the Kennington Green consultation page.

Monitoring passenger movements in Kennington station

We have sent Southwark Council our proposal for monitoring passenger movements at Kennington Tube station. This analysis will be used to compare forecast and actual passenger numbers, get insight into people's movements through the station and to ensure our customers' safety.

This protocol is required by Southwark as part of our approval to build and operate the Northern line extension. You can comment on the method we propose on Southwark's planning application portal.

Community Liaison Groups

We are committed to engaging with the communities and stakeholders that may be affected by the NLE. We have set up five Community Liaison Groups (CLGs) which meet quarterly.

One group considers route wide issues:

  • Core CLG

Four consider more local issues specific to work sites and tunnelling along the route:

  • Battersea CLG
  • Kennington Green CLG
  • Kennington Park and Newington CLG
  • Nine Elms and Oval CLG

These public meetings are chaired by councillors and held in public. Residents are welcome to attend as observers.

The minutes of the meetings are published after each meeting.

Check back here for dates for the next series of meetings.

Ground movement contours

The NLE works will cause some ground movement which may affect some properties close to the work sites and above the running tunnel routes. Properties in these areas are shown within the blue line on the drawing below.

All residents affected have been contacted for a defects survey.
