  • Diverting the NTS

  • First Steps


    No work can be carried out in the vicinity of a pipeline without the written consent of National Grid.

    To ask about proposed work near pipelines, call 0800 688 588, write to National Grid Plant Protection, National Grid, Block 1, Brick Kiln Street, Hinckley LE10 ONA or email

    Remember to supply a clearly identifiable plan, site grid reference or postcode, a works start date, contact details and details of the planned work.

    The team will check the location of any assets in the vicinity of the proposed works, and say if the work is of high, moderate or low risk.  It may be necessary to divert the pipeline before work can commence.

    You will be sent a map showing the location of the asset, together with advice on 'Avoiding danger from underground services' (HSG47) and specific guidance on working near the asset or assets found.

    National Grid should be contacted at least seven days in advance of any works.

    Additionally is a free online enquiry service giving instant results from a grid reference, postcode or street name.  

    If your result is within a National Grid zone of interest you can click directly through to the Plant Protection team to request plant location details.
