Prior notification (Telecommunications)

Last Modified December 11, 2014

Certain forms of telecommunications development, for example, mobile telephone masts, fall under permitted development and are subject to prior approval from us. The prior approval procedure means that the principle of development is not an issue and we can only consider the siting and appearance of the proposal.

We have 56 days in which to let the mast operators know whether prior approval is required for siting and appearance, and to let the operator know of our decision to allow or refuse approval. There is no power to extend the 56 day period.

The prior approval procedure applies to the construction, installation, alteration or replacement of:

  • A ground-based mast of up to and including 15 metres in height;
  • A mast of up to, and including, 15 metres in height installed on a building or structure;
  • An antennae (including any supporting structure) which exceeds the height of the building or structure (other than a mast) by 4 metres or more at the point of where it is installed or to be installed;
  • A public call box;
  • Radio equipment housing with a volume of 2.5 cubic metres;
  • Development ancillary to radio equipment housing (for example, fences or access roads).
