  • Trees and vegetation near gas pipelines

  • Before any tree planting is carried out on the underground gas pipelines permanent easement strip written approval should be obtained from National Grid .  Please contact us to discuss your proposals at the earliest opportunity. Where approval is given it is subject to National Grid retaining the right to remove any trees which might become a danger, or restrict access to the underground gas pipeline at any time in the future. The written consent to plant trees in the vicinity will state what area may be planted and also the type of tree.

  • The only hardwood plants which may be planted directly across the pipeline are hedge plants such as quick thorn and blackthorn. However these should only be planted where a hedge is necessary either for screening purposes or to indicate a field boundary.

    The following trees must not be planted within 6m of the underground gas pipeline:

    • Ash, cedar, larch, beech, elm, horse chestnut, sweet chestnut, London plane, hornbeam, lime, lime alder, scots pine, black pine, oak, sycamore, apple, plum, cherry, pear, and also included in this category are most conifers.
    • The above trees should only be planted as individual specimens or a single row in the area between 6 m and 10 m of the pipeline. Dense mass planting should only be carried out at a distance greater than 10 m from the underground gas pipeline.

    The following trees must not be planted within 10 m of the underground gas pipeline:

    • Poplar and willow

    In cases where screening is required, the following are shallow rooting and may be planted over the pipeline, road and field crossings, etc. where necessary:
