Noise Calculations for Air Source Heat Pump Locations
Noise calculations for air source heat pump locations may be required if the location does not comply with Planning guidance.
Air Source Heat pumps are now within permitted development for Planning Permission purposes since 1st December 2011.
Please click our maps for SAP Calculations/SAP Ratings in your area.
The guidance below should be followed.
Limits to be met (Information from the Planning Portal website)
- Development is permitted only if the air source heat pump installation complies with the Microgeneration Certification Scheme Planning Standards or equivalent standards. Read more about the scheme.
- The volume of the air source heat pump’s outdoor compressor unit (including housing) must not exceed 0.6 cubic metres.
- Only the first installation of an air source heat pump would be permitted development, and only if there is no existing wind turbine on a building or within the curtilage of that property. Additional wind turbines or air source heat pumps at the same property requires an application for planning permission.
- All parts of the air source heat pump must be at least one metre from the property boundary.
- Installations on pitched roofs are not permitted development. If installed on a flat roof all parts of the air source heat pump must be at least one metre from the external edge of that roof.
- Permitted development rights do not apply for installations within the curtilage of a Listed Building or within a site designated as a Scheduled Monument.
- On land within a Conservation Area or World Heritage Site the air source heat pump must not be installed on a wall or roof which fronts a highway or be nearer to any highway which bounds the property than any part of the building.
- On land that is not within a Conservation Area or World Heritage Site, the air source heat pump must not be installed on a wall if that wall fronts a highway and any part of that wall is above the level of the ground storey.
In addition, the following conditions must also be met. The air source heat pump must be:
- Used solely for heating purposes.
- Removed as soon as reasonably practicable when it is no longer needed for microgeneration.
- 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.
You may wish to discuss with the Local Planning Authority for your area whether all of these limits and conditions will be met.
If the air source heat pump is closer to the boundary than the guidance suggests then Noise Calculations can be carried out to justify this.
