Class C – Microwave antenna on buildings under 15m

We will not be expanding upon Class C, which is for microwave antenna on buildings under 15m, within Planning Geek at this time. Better known as satellite dishes. This does not apply to residential dwellings. Please see Class H of Part 1 for this.

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

Legislation

Class C – other electronic communications development: microwave antenna

Permitted development

C. The installation, alteration or replacement on any building or other structure of a height of less than 15 metres of a microwave antenna.

Development not permitted

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

(a) the building is a dwellinghouse or other structure 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—
(i) more than 2 antennas;
(ii) a single antenna exceeding 1 metre in length;
(iii) 2 antennas which do not meet the relevant size criteria;
(iv) an antenna installed on a chimney, where the length of the antenna would exceed 0.6 metres;
(v) an antenna installed on a chimney, where the antenna would protrude over the chimney;
(vi) an antenna with a cubic capacity in excess of 35 litres;

(e) in the case of an antenna to be installed on a roof without a chimney, the highest part of the antenna would be higher than the highest part of the roof;

(f) in the case of an antenna to be installed on a roof with a chimney, the highest part of the antenna would be higher than the highest part of the chimney stack, or 0.6 metres measured from the highest part of the ridge tiles of the roof, whichever is the lowest; or

(g) 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.

Condition

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

(a) the antenna is, so far as 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.

Interpretation of Class C

C.3 The relevant size criteria for the purposes of paragraph C.1(d)(iii) are that:

(a) only 1 of the antennas may exceed 0.6 metres in length; and

(b) any antenna which exceeds 0.6 metres in length must not exceed 1 metre in length.
