Small scale Wind:
I understand that the proposal is for small scale wind within a residential garden.
Small scale wind generating equipment is generally split into two categories, ‘building mounted’ and ‘standalone’, I will address these in turn:-
1) Building mounted wind turbines for Householders.
The installation, of a building mounted wind turbine for domestic use can be considered to be Permitted Development under Schedule 2, Part 14, Class A of the General Permitted development Order, provided that ALL of the limits and conditions listed below are met:
- Permitted development rights for building mounted wind turbines apply only to installations on detached houses (not blocks of flats) and other detached buildings within the boundaries of a house or block of flats.
- Development is permitted only if the building mounted wind turbine installation complies with the Microgeneration Certification Scheme Planning Standards (MCS 020) or equivalent standards. Read more about the scheme.
- The installation must not be sited on safeguarded land.
- Only the first installation of any wind turbine would be permitted development, and only if there is no existing air source heat pump at the property. Additional wind turbines or air source heat pumps at the same property requires an application for planning permission.
- No part (including blades) of the building mounted wind turbine should protrude more than three metres above the highest part of the roof (excluding the chimney) or exceed an overall height (including building, hub and blade) of 15 metres, whichever is the lesser.
- The distance between ground level and the lowest part of any wind turbine blade must not be less than five metres.
- No part of the building mounted wind turbine (including blades) must be within five metres of any boundary.
- The swept area of any building mounted wind turbine blade must be no more than 3.8 square metres.
The wind turbine itself must:
- use non-reflective materials on blades.
- be removed as soon as reasonably practicable when no longer needed for microgeneration.
- be sited, so far as practicable, to minimise its effect on the external appearance of the building and its effect on the amenity of the area.
Important Note - In Conservation Areas, an installation is not permitted if the building mounted wind turbine would be on a wall or roof slope which fronts a highway.
Permitted development rights do not apply to a turbine within the curtilage of a Listed Building or within a site designated as a Scheduled Monument or on specially designated land other than Conservation Areas.
2) Standalone Wind Turbines for Householders.
The installation of a standalone (not building mounted) wind turbine within the boundaries of a house can be considered to be Permitted Development under Schedule 2, Part 14, Class B of the General Permitted development Order, providing that all of the below limits and conditions are met: -
- The wind turbine installation must comply with the Microgeneration Certification Scheme Planning Standard (MCS 020) or equivalent standards.
- The installation must not be sited on safeguarded land.
- Only the first installation of any wind turbine would be permitted development, and only if there is no existing air source heat pump at the property. Additional wind turbines or air source heat pumps at the same property would require an application for planning permission.
- The highest part of the standalone wind turbine must not exceed 11.1 metres.
- The distance between ground level and the lowest part of any wind turbine blade must not be less than five metres.
- An installation is not permitted if any part of the standalone wind turbine (including blades) would be in a position which is less than a distance equivalent to the overall height of the turbine (including blades) plus 10 per cent of its height when measured from any point along the property boundary.
- The swept area of any standalone wind turbine blade must be no more than 3.8 square metres.
In addition, the following conditions must also be met. The wind turbine must:
- use non-reflective materials on blades.
- be removed as soon as reasonably practicable when no longer needed for microgeneration.
- be sited, so far as is practicable, to minimise its effect on the external appearance of the building and its effect on the amenity of the area.
- * Designated land includes national parks and the Broads, Areas of Outstanding Natural Beauty, and World Heritage Sites.
Important Note - In Conservation Areas, development would not be permitted if the stand alone wind turbine would be installed so that it is nearer to any highway which bounds the curtilage (garden or grounds) of the house or block of flats than the part of the house or block of flats which is nearest to that highway. Permitted development rights do not apply to a turbine within the curtilage of a Listed Building or within a site designated as a Scheduled Monument or on specially designated land other than Conservation Areas.
Note - In both Standalone and building mounted development, only the first installation per dwelling is considered PD, subsequent additions, or proposals for multiple sets of generating equipment would require planning permission.
