Northern line extension

Where we will be working

The main work sites are at:

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

Preparation works started at these sites in spring 2015. In 2017 the main tunnelling will get underway from Battersea to the new shafts at Kennington Green and Kennington Park.

The joint venture Ferrovial Agroman Laing O'Rouke is designing and building the Northern Line Extension (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 extension 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 Northern line extension has shown it could generate substantial benefits to the area.

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

Community Liaison Groups

We are committed to ongoing engagement with the communities and stakeholders that may be affected by the Northern line extension. We have set up five Community Liaison Groups (CLGs).

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

Groups meet quarterly. The meetings are chaired by councillors and held in public. Residents are welcome to attend as observers. Meetings start at 18:30.

The next series of meetings will be:

Battersea Power Station: Wednesday 1 February, 18:30-20:00

Ascalon Street
London SW8 4DJ

Kennington Green: Tuesday 24 January, 18:30-20:00

Notice of intention letters

Residents may have received a Notice of Intention letter in the past weeks. These letters explain that we are exercising powers under the TWAO for the acquisition of subsoil in order to start the tunnelling works.

The Notice of Intention is the first of three stages of a General Vesting Declaration (GVD) we will go through in order to make a compulsory purchase of the subsoil. Notice of Intention documents are also on lamp posts relating to unregistered land.

We are not making compulsory purchases of properties or land on the surface, just the subsoil.

If you have any questions or concerns please contact for more information or read the frequently asked questions below.

Ground movement contours

The NLE works will cause some ground movement which may affect a number of 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.

These properties are eligible for a defect survey which would be done before we start works. Defect surveys have already been carried out on a number of properties directly adjacent to the Kennington shaft sites, Nine Elms and Battersea construction sites.

A defect survey is a written and photographic record of the property condition before work starts and will be done by an independent and qualified surveyor.
