• London Gas Mains Replacement
    • We are investing nearly £1 billion in replacing and upgrading more than 1,800 miles of metal gas mains in London with safer and more durable modern pipes. The programme will reduce the amount of unplanned work on our gas network and is essential to provide safe and reliable energy to the people in our communities running businesses, schools and homes.

      We are continuing to invest in the London gas supply network which provides gas, unnoticed beneath roads and footpaths, to more than two million customers. We have finished our work in King’s Road, between Stanley Bridge (railway-bridge to the west of Lots Road) and Gunter Grove, to replace three large metal gas mains with tough new pipes.

      We need to replace the gas main from Gunter Grove and along Fulham Road and we are currently planning the extent of the work that we are able to carry out on Fulham Road in 2017 with the Council and Transport for London (TfL).

      We are also preparing to lay a new gas pipeline from Chelsea to Battersea in a tunnel beneath the River Thames. To do this we need to install some equipment in the grounds of Royal Hospital Chelsea and Battersea Park to control the gas flow. This will be mainly underground with a small kiosk and pipe above the ground. (See ‘Tunnel under the River Thames’.)

      There is a coordination group to plan our work and to consider how we can reduce its impact on the local community. This is hosted by the Council and includes TfL and the emergency services.

      We are also setting up a community forum to listen to feedback from local businesses and residents to help us develop the traffic management plans. If you would like to be involved in this please call the community relations team on 0800 389 8261 or email nationalgrid@londongasmains.co.uk.

  • Latest Update: Chelsea and Fulham

    We are preparing to replace and upgrade the old metal gas main from 15 Gunter Grove, along Fulham Road, past the Chelsea and Westminster Hospital, to the junction with Beaufort Street with new pipes made of more durable material. The work is scheduled to take place from May to September 2017 and forms part of a five-year project that extends into the City of Westminster and London Borough of Wandsworth.

    Due to the scale of the project and for everyone’s safety there is need to close the westbound lane of Fulham Road between Beaufort Street and Gunter Grove during certain periods of the work. Where possible temporary traffic signals will be used to minimise the time and extent of the road closure. It is likely there will be significant disruption in the area so it will be important to allow more time for journeys.

    The gas mains replacement programme is crucial to providing safe and reliable energy to homes and businesses and will reduce the amount of unplanned work to repair ageing gas pipes. It will also support London’s economic growth.

    Throughout the work all shops and businesses will be open as usual and we will make every effort to minimise any inconvenience to people who work, live or travel through the area. We have planned this work with extensive discussions over many months with stakeholders including the emergency services, Chelsea and Westminster Hospital, Royal Borough of Kensington and Chelsea and Transport for London (TfL) traffic management and buses.

    Tunnel under the River Thames

    We are constructing a 330-metre long tunnel under the River Thames by digging shafts 30 metres deep on either side of the river between Royal Hospital Chelsea and Battersea Park. We will lower a tunnel boring machine (TBM) into the shaft in the grounds of Royal Hospital Chelsea. Remotely controlled by an operator on the surface, the TBM will dig the tunnel and line it with concrete segments as it moves along. Once tunnelling is complete a new gas pipe will be installed.

    The first shaft, which will have a diameter of 7.5m, will be sunk in the grounds of the Royal Hospital Chelsea between January and March 2017. The site will then be cleared to avoid any disruption to the events over the summer. Work will then shift to Battersea Park where the second shaft – with a diameter of 6m – will be sunk between April and August 2017.

    At each site we will be working for approximately 16 months in total. The work will be split into two phases to avoid special events such as the Chelsea Flower Show and the arts fair Masterpiece. We anticipate that the project will be completed in 2018.

    During construction we will need work compounds in the Royal Hospital Grounds and the north-east corner of Battersea Park. Once construction is complete we will remove the compounds. To maintain and operate the tunnel, small kiosks (half a metre long and one metre high) will need to remain along with a three metre tall pipe.

    Throughout our work, we will maintain public access to Battersea Park. However, we do need to close a small section of footpath. This requires a short diversion and we will put signs in place. We have made sure that the main footpath that runs between the Park and the Battersea development is kept open.

  • Community consideration

    This work is part of our investment in replacing and upgrading the gas mains in London with safer and more durable modern pipes. The programme will reduce the amount of unplanned work on our gas network and is essential to provide safe and reliable energy to the people in our communities running businesses, schools and homes.

    For most of the work we insert the new pipes into the old mains. This reduces the need for digging and minimises disruption to residents, businesses and road users. We will use sound reducing technologies and avoid digging long trenches where possible. We keep local communities informed of our work and liaise closely with local authorities. We also work with companies and agencies carrying out other infrastructure projects so that our work is coordinated with others.

    We are listening to local businesses and residents in developing the traffic management plan. We are doing everything possible to reduce the impact while being mindful of the different needs of residents, businesses and motorists. Throughout the work all shops and businesses will be open as usual and we will maintain access for deliveries. I would like to thank you in advance for your patience and cooperation.
