Do I need planning permission for air conditioning in Loch Lomond and The Trossachs National Park?
Probably yes for cooling: Scotland's permitted-development class for heat pumps (Class 6H) covers heating and hot water only, so an air-conditioning unit used for cooling is not covered by that class and a planning application may be needed; a heat pump used only for heating can be permitted if it meets the noise and siting rules (checked 25 Sep 2026). Loch Lomond and The Trossachs National Park has 7 conservation-area records on file (status on-record, snapshot 25 Sep 2026).
application may be needed
What to include in an application
- SCO-01. Is the building a house, or a building that is wholly flats?
- SCO-02. How many outdoor units will the building have once this one is installed?
- SCO-06. Is this exact address in a World Heritage Site?
- SCO-06. Is the building listed? A postcode search cannot clear this.
