Further guidance is available in Information Leaflet 13 A Householder’s Planning Guide for the Installation of Antennas, including Satellite Dishes” and is also available from local area planning offices.
Note: An antenna should so far as is practicable:
  • be sited so as to minimise its effect on the external appearance of the building and
  • be removed when no longer needed for reception or transmission purposes
The length of an antenna is to be measured in any linear direction, but the measurement does not include any projecting feed element, reinforcing rim, mounting or brackets.
If you live in a house which is a listed building, it is likely that you will need Listed Building Consent for any building operations. If the development is within the curtilage of a listed building you may need to submit a planning application for the work unless listed building consent has already been granted. Your local area planning office will be able to advise you.
