For Class F and Class G substitute—

“

Class F
Permitted development F. The provision of a ground or water source heat pump within the curtilage of a dwellinghouse.
Development not permitted F.1
Development is not permitted by Class F if—

(a)

any part of the heat pump or its housing would be within 3 metres of the boundary of the curtilage of the dwellinghouse and would exceed 4 metres in height;

(b)

it would involve the provision of any heat pump within an area of special scientific interest or a site of archaeological interest.

Class G
Permitted development G. The installation, alteration or replacement of an air source heat pump within the curtilage of a dwellinghouse.
Development not permitted G.1
Development is not permitted by Class G if—

(a)

it would result in the presence within the curtilage of more than one air source heat pump;

(b)

any part of the air source heat pump would be installed within 1 metre of the boundary of the curtilage of another dwelling house;

(c)

any part of the air source heat pump would be situated on land forward of a wall which—

(i)

faces onto a road; and

(ii)

forms either the principal elevation or a side elevation of the original dwellinghouse.

(d)

in the case of a dwellinghouse within a World Heritage Site or conservation area any part of the air source heat pump faces onto and is visible from a road;

(e)

the external unit of the air source heat pump would exceed 3 metres in height;

(f)

the air source heat pump would be installed on a roof;

(g)

the air source heat pump would be situated within the curtilage of a listed building unless listed building consent for the development has previously been granted.

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

(a)

the air source heat pump would be used to provide heat for use within the curtilage of the dwellinghouse;

(b)

when no longer used to provide heat it shall be removed as soon as reasonably practicable; and

(c)

the air source heat pump must comply with MCS planning standards or equivalent standards.

Interpretation of Class G G.3 In Class G “MCS Planning Standards” means the product and installation standards for air source heat pumps specified in the Microgeneration Certification Scheme MCS 020 ^f1.
