PART 25OTHER TELECOMMUNICATIONS DEVELOPMENT
Class A
Permitted development
A. The installation, alteration or replacement on any building or other structure of a microwave antenna and any structure intended for the support of a microwave antenna.
Development not permitted
A.1. Development is not permitted by Class A if—
(a)the building is a dwellinghouse;
(b)the development is permitted by Part 24;
(c)the building or structure is less than 15 metres in height;
(d)the development would result in the presence on the building or structure of more than two microwave antennas;
(e)in the case of a satellite antenna, the size of the antenna, including its supporting structure but excluding any projecting feed element, would exceed 90 centimetres;
(f)in the case of a terrestrial microwave antenna—
(i)the size of the antenna, when measured in any dimension but excluding any projecting feed element, would exceed 1.3 metres; and
(ii)the highest part of the antenna or its supporting structure would be more than 3 metres higher than the highest part of the building or structure on which it is installed or is to be installed; or
(g)it is on article 1(5) land.
Conditions
A.2. Development is permitted by Class A subject to the following conditions—
(a)the antenna shall, so far as is practicable, be sited so as to minimise its effect on the external appearance of the building or structure on which it is installed;
(b)an antenna no longer needed for the reception or transmission of microwave radio energy shall be removed from the building or structure as soon as reasonably practicable.
