This is one of the most common questions we get asked here at Quantech Environmental.
In general, Planning Permission is not required for Air Conditioning units for domestic premises as long as the units are installed in accordance with the conditions set down under Permitted Development Rights. This means you won’t have to apply for Planning Permission but there are exceptions, for example:
If your house is in a Conservation Area
Or in an Area of Outstanding Natural Beauty
Or if your house is a listed building
So, what are the conditions of Permitted Development Rights?
The external unit is not installed on a pitched roof or a chimney breast
There is no wind turbine at the property
The external unit is not installed within 1 metre of the edge of a flat roof
The volume of the external condensing unit (the outdoor unit) is not more than 0.6m³
The condensing unit is more than 1 metre away from the boundary of the property
The condensing unit is sited at ground floor level
There is only one condensing unit on the property
Whilst neighbours cannot complain to the council about the appearance or the aesthetic of your outdoor unit, they can do so on the ground of it being too noisy.
This can be complicated to get right as noise levels are subjective so please do get advice from us at Quantech Environmental on this matter.
