Class A – installation or alteration etc of solar equipment on domestic premisesE+W
Permitted developmentE+W
A. The installation, alteration or replacement of microgeneration solar PV or solar thermal equipment on—
(a)a dwellinghouse or a block of flats; or
(b)a building situated within the curtilage of a dwellinghouse or a block of flats.
Development not permittedE+W
A.1 Development is not permitted by Class A if—
(a)the solar PV or solar thermal equipment would protrude more than 0.2 metres beyond the plane of the wall or [, in the case of a pitched roof,] the roof slope when measured from the perpendicular with the external surface of the wall or [pitched] roof slope;
(b)[in the case of solar PV or solar thermal equipment on a pitched roof,] it would result in the highest part of the solar PV or solar thermal equipment being higher than the highest part of the roof (excluding any chimney);
[(ba)in the case of solar PV or solar thermal equipment on a flat roof, it would result in the highest part of the solar PV or solar thermal equipment being more than 0.6 metres higher than the highest part of the roof (excluding any chimney);]
(c)in the case of land within a conservation area or which is a World Heritage Site, the solar PV or solar thermal equipment would be installed on a wall which fronts a highway;
(d)the solar PV or solar thermal equipment would be installed on a site designated as a scheduled monument; or
(e)the solar PV or solar thermal equipment would be installed on a building within the curtilage of the dwellinghouse or block of flats if the dwellinghouse or block of flats is a listed building.
ConditionsE+W
A.2 Development is permitted by Class A subject to the following conditions—
(a)solar PV or solar thermal equipment is, so far as practicable, sited so as to minimise its effect on the external appearance of the building;
(b)solar PV or solar thermal equipment is, so far as practicable, sited so as to minimise its effect on the amenity of the area; ...
[(ba) in the case of solar PV or solar thermal equipment installed on a flat roof located on article 2(3) land, before beginning development the developer must apply to the local planning authority for a determination as to whether the prior approval of the local planning authority will be required with respect to the impact of the appearance of the solar PV or solar thermal equipment on that land;
(bb) in relation to an application under sub-paragraph (ba), paragraphs J.4(3) to J.4(12) of this Part apply as if “Class A” substitutes the reference to “Class J” in paragraph J.4(4); and]
(c)solar PV or solar thermal equipment is removed as soon as reasonably practicable when no longer needed.
