Class B – Microwave antenna on buildings over 15m

We will not be expanding upon Class B, which is for microwave antenna or better known as satellite dishes. This includes the installation, alteration or replacement on any building or other structure of a height of 15 metres or more including any structure intended for the support of a microwave antenna, within Planning Geek at this time.

The legislation can be found below. If you need the guidance of Planning Geek in the process for Class B, please contact us for any assistance or book a Zoom call today.

Legislation

Class B – other electronic communications development

Permitted development

B. The installation, alteration or replacement on any building or other structure of a height of 15 metres or more of a microwave antenna and any structure intended for the support of a microwave antenna.

Development not permitted

B.1 Development is not permitted by Class B if—

(a) the building is a dwellinghouse or the building or structure is within the curtilage of a dwellinghouse;

(b) it would consist of development of a kind described in Class A of this Part;

(c) it would consist of the installation, alteration or replacement of system apparatus within the meaning of section 8(6) of the Road Traffic (Driver Licensing and Information Systems) Act 1989 (definitions of driver information systems etc);

(d) it would result in the presence on the building or structure of more than 4 antennas;

(e) in the case of an antenna installed on a chimney, the length of the antenna would exceed 0.6 metres;

(f) in all other cases, the length of the antenna would exceed 1.3 metres;

(g) it would consist of the installation of an antenna with a cubic capacity in excess of 35 litres;

(h) 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
(i) in the case of article 2(3) land, it would consist of the installation of an antenna—
(i) on a chimney, wall or roof slope which faces onto, and is visible from, a highway;
(ii) in the Broads, on a chimney, wall or roof slope which faces onto, and is visible from, a waterway.

Conditions

B.2 Development is permitted by Class B subject to the following conditions—

(a) the antenna is, so far as is practicable, sited so as to minimise its effect on the external appearance
of the building or structure on which it is installed; and

(b) an antenna no longer needed for reception or transmission purposes is removed from the building
or structure as soon as reasonably practicable.
