Northern line extension

Two new stations are being built at Nine Elms and Battersea Power Station.

On Thursday, 8 July 2021, we announced the start of trial operations on the new 3km twin-tunnel railway between Kennington and Battersea Power Station, via Nine Elms.

Main worksites

  • Battersea Power Station (new station)
  • Kennington Green (headhouse)
  • Kennington Park (headhouse)
  • Kennington Tube station (new cross passages)
  • Nine Elms next to Wandsworth Road and Pascal Street (new station)

The joint venture Ferrovial Agroman Laing O'Rouke is designing and building the NLE.

Main tunnelling finished in November 2017 after two tunnels were created between Battersea and new shafts at Kennington Green and Kennington Park.

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

Benefits of the NLE

The NLE will improve transport links and public spaces in the Vauxhall, Nine Elms and Battersea area, 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.


New head houses/shafts

As part of the project we've built two new head houses and shafts at Kennington Green and Kennington Park. These will provide ventilation and emergency access to the Tube once the extension is open.

More information is on the Kennington Green consultation page and the Kennington Park consultation page.

Kennington station zone change

On 16 May 2021 Kennington changed from a Zone 2 station to a Zone 1/2 station. Customers travelling to central London from new stations at Nine Elms and Battersea Power Station will only pay a Zone 1 fare.

Customers who travel to a Zone 1 station from Kennington will also see their pay as you go fare reduced.

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 (CLGs)

We are committed to engaging with the communities and stakeholders that may be affected by the NLE.

Four CLGs meet quarterly - although these public meetings are currently suspended.

The meetings consider 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

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

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.
