"PART 40 INSTALLATION OF DOMESTIC MICROGENERATION EQUIPMENT

Class A

Permitted development

A. The installation, alteration or replacement of solar PV or solar thermal equipment on–

(a) a dwellinghouse; or

(b) a building situated within the curtilage of a dwellinghouse.

Development not permitted

A.1. Development is not permitted by Class A, in the case of solar PV or solar thermal equipment installed on an existing wall or roof of a dwellinghouse or a building within its curtilage if–

(a) the solar PV or solar thermal equipment would protrude more than 200 millimetres beyond the plane of the wall or the roof slope when measured from the perpendicular with the external surface of the wall or roof slope;

(b) 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);

(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–

(i) on a wall forming the principal or side elevation of the dwellinghouse and would be visible from a highway; or

(ii) on a wall of a building within the curtilage of the dwellinghouse and would be visible from a highway; or

(d) the solar PV or solar thermal equipment would be installed on a building within the curtilage of the dwellinghouse if the dwellinghouse is a listed building.

Conditions

A.2. Development is permitted by Class A subject to the following conditions–

(a) solar PV or solar thermal equipment installed on a building must, so far as practicable, be sited so as to minimise its effect on the external appearance of the building;

(b) solar PV or solar thermal equipment must, so far as practicable, be sited so as to minimise its effect on the amenity of the area; and

(c) solar PV or solar thermal equipment no longer needed for microgeneration must be removed as soon as reasonably practicable.

Class B

Permitted development

B. The installation, alteration or replacement of stand alone solar within the curtilage of a dwellinghouse.

Development not permitted

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

(a) it would result in the presence within the curtilage of more than one stand alone solar; or

(b) any part of the stand alone solar–

(i) would exceed four metres in height above ground level;

(ii) would be situated within five metres of the boundary of the curtilage of the dwellinghouse and would–

(aa) exceed two metres in height above ground level; or

(bb) be situated within five metres of the highway;

(iii) would, in the case of land within a conservation area or which is a World Heritage Site, be situated within any part of the curtilage of the dwellinghouse and would be visible from the highway; or

(iv) would be situated within the curtilage of a listed building; or

(c) the surface area of the solar panels forming part of the stand alone solar would exceed nine square metres or any dimension of its array (including any housing) would exceed three metres.

Conditions

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

(a) stand alone solar must, so far as practicable, be sited so as to minimise its effect on the amenity of the area;

(b) stand alone solar which is no longer needed for microgeneration must be removed as soon as reasonably practicable.

Class C

Permitted development

C. The installation, alteration or replacement of a ground source heat pump within the curtilage of a dwellinghouse.

Class D

Permitted development

D. The installation, alteration or replacement of a water source heat pump within the curtilage of a dwellinghouse.

Class E

Permitted development

E. The installation, alteration or replacement of a flue, forming part of a biomass heating system, on a dwellinghouse.

Development not permitted

E.1 Development is not permitted by Class E if–

(a) the height of the flue would exceed the highest part of the roof by one metre or more; or

(b) in the case of land within a conservation area or which is a World Heritage Site, the flue would be installed on a wall or roof slope forming the principal or side elevation of the dwellinghouse and would be visible from a highway.

Class F

Permitted development

F. The installation, alteration or replacement of a flue, forming part of a combined heat and power system, on a dwellinghouse.

Development not permitted.

F.1 Development is not permitted by Class F if–

(a) the height of the flue would exceed the highest part of the roof by one metre or more; or

(b) in the case of land within a conservation area or which is a World Heritage Site, the flue would be installed on a wall or roof slope forming the principal or side elevation of the dwellinghouse and would be visible from a highway.

Interpretation of Part 40

G.1. For the purposes of Part 40–

• "dwellinghouse" includes a building which consists wholly of flats or which is used for the purposes of a dwellinghouse;

• "microgeneration" has the same meaning as in section 82(6) of the Energy Act 2004(3); and

• "stand alone solar" means solar PV or solar thermal equipment which is not installed on a building."

Explanatory Note

(This note is not part of the Order)

This Order amends Schedule 2 to the Town and Country Planning (General Permitted Development Order 1995 ("the 1995 Order"). Schedule 2 confers permitted development rights in respect of certain development. Where such rights apply, no specific application for planning permission is needed.

Article 2(4) inserts a new Part 40 into Schedule 2 of the 1995 Order. It provides permitted development rights for the installation of specified types of microgeneration equipment on or within the curtilage of dwellinghouses or flats, subject to specified criteria and conditions. Article 2(2) and 2(3) make consequential changes.

A regulatory impact assessment has been prepared in relation to this Order. Copies are available by post from the Welsh Assembly Government at Cathays Park, Cardiff CF10 3NQ.
