(b) in the case of the alteration or replacement of apparatus already installed (other than on a building or other structure), the apparatus, excluding any antenna, would when altered or replaced exceed the height of the existing apparatus or a height of 15 metres above ground level, whichever is the greater;

(c) in the case of the installation, alteration or replacement of apparatus on a building or other structure, the height of the apparatus (taken by itself) would exceed—

(i) 15 metres, where it is installed, or is to be installed, on a building or other structure which is 30 metres or more in height; or

(ii) 10 metres in any other case;

(d) in the case of the installation, alteration or replacement of apparatus on a building or other structure, the highest part of the apparatus when installed, altered or replaced would exceed the height of the highest part of the building or structure by more than—

(i) 10 metres, in the case of a building or structure which is 30 metres or more in height;

(ii) 8 metres, in the case of a building or structure which is more than 15 metres but less than 30 metres in height;

(iii) 6 metres in any other case;

(e) in the case of the installation, alteration or replacement of any apparatus other than—

(i) a mast,

(ii) an antenna,

(iii) a public call box,

(iv) any apparatus which does not project above the level of the surface of the ground, or

(v) radio equipment housing,

the ground or base area of the structure would exceed 1.5 square metres;

(f) in the case of the installation, alteration or replacement of an antenna on a building or structure (other than a mast) which is less than 15 metres in height; on a mast located on such a building or structure; or, where the antenna is to be located below a height of 15 metres above ground level, on a building or structure (other than a mast) which is 15 metres or more in height—

(i) the antenna is to be located on a wall or roof slope facing a highway which is within 20 metres of the building or structure on which the antenna is to be located;

(ii) in the case of dish antennas, the size of any dish would exceed 0.9 metres or the aggregate size of all of the dishes would exceed 1.5 metres, when measured in any dimension;

(iii) in the case of antennas other than dish antennas, the development would result in the presence on the building or structure of more than two antenna systems; or

(iv) the building or structure is a listed building or a scheduled monument;

(g) in the case of the installation, alteration or replacement of an antenna on a building or structure (other than a mast) which is 15 metres or more in height, or on a mast located on such a building or structure, where the antenna is located at a height of 15 metres or above, measured from ground level—

(i) in the case of dish antennas, the size of any dish would exceed 1.3 metres or the aggregate size of all of the dishes would exceed 3.5 metres, when measured in any dimension;

(ii) in the case of antenna systems other than dish antennas, the development would result in the presence on the building or structure of more than three antenna systems; or

(iii) the building or structure is a listed building or a scheduled monument;

(h) in the case of development of any article 1(5) land, it would consist of—

(i) the installation or alteration of an antenna or of any apparatus which includes or is intended for the support of such an antenna; or

(ii) the replacement of such an antenna or such apparatus by an antenna or apparatus which differs from that which is being replaced,

unless the development is carried out in an emergency;

(i) 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(1) (definitions of driver information systems etc.);

(j) in the case of the installation of a mast, on a building or structure which is less than 15 metres in height, such a mast would be within 20 metres of a highway;

(k) in the case of the installation, alteration or replacement of radio equipment housing—

(i) the development is not ancillary to the use of any other telecommunication apparatus;

(ii) it would exceed 90 cubic metres or, if located on the roof of a building, it would exceed 30 cubic metres;

(iii) on any article 1(5) land, it would exceed 2 cubic metres, unless the development is carried out in an emergency;

or

(l) it would consist of the installation, alteration or replacement of any telecommunication apparatus on, or within the curtilage of, a dwellinghouse.
