Whether an air conditioning unit requires planning permission depends on its size and other factors. Our best advice is to speak to your local council as the rules vary between each authority

Small Systems: Most small air conditioning systems fall under permitted development rights and typically do not require planning permission.

Large Systems: You may need planning permission if your system meets any of the following criteria:

  • It is located less than one meter away from any property boundaries.
  • It is within one meter of the edge of a flat roof.

Other factors that may influence the need for planning permission include:

– The location of the property (e.g., in a conservation area or scenic location).

– If the property is an apartment in a central location.

– If the property is within a conservation area

– If the property is listed building (other applications will have to be obtained)
