    How many sites does National Grid Property own?
    We own and are responsible for the management of around 350 of National Grid’s surplus sites.

    What land does National Grid own?
    We own a very diverse portfolio of land ranging from former town gasworks and depots to storage facilities and residential properties.

    What is brownfield land?
    Brownfield land is land which has been previously developed.

    What is a town gasworks?
    Town gasworks manufactured household gas from coal between the 1860s and 1960s. Initially built to power factories in the industrial revolution, town gasworks sprung up in towns and cities across the UK as demand for gas soared. During the early 1960s the discovery of large reserves of Natural Gas in the North Sea led to town gasworks becoming redundant.

    Why can’t you leave the sites in their current condition?
    Much of our former industrial land has been under-used for many years, and if we leave it untreated there is little chance it will ever return to benefiecial use. We are committed to tackling the industrial legacy of these sites’ former use as gas manufacturing facilities, and giving this redundant land a new lease of life. 

    You are working close to my home, is my gas supply going to be affected?
    Our work involves the removal of redundant gas infrastructure. Gas is delivered to homes by distribution networks so should not be affected. To learn more about the distribution network where you live visit our information page

    What will you do with land once you have cleaned it up?
    Following decommissioning and remediation of a site, it will be marketed through our real estate service provider, BNP Paribas Real Estate.
