Air conditioning: planning permission or permitted development?

Sevda Kucuk · 4 August 2026

Installing an air conditioning unit, external condenser or air source heat pump may fall under Permitted Development rights or require a full planning application, depending on the property and the position of the external unit.

AVA Home Design provides professional advice and planning application services for air conditioning units, external condenser units and air source heat pump systems.

Depending on the property, location and position of the external unit, your installation may be possible under Permitted Development rights or may require a full planning application. We can assess your proposal and advise you on the most suitable planning route before you proceed.

Whether you are installing an air conditioning unit on a house, flat or commercial property, AVA Home Design can help you understand the planning requirements and prepare the necessary application.

We work with homeowners and property owners across Hillingdon, Uxbridge and surrounding London areas, helping clients obtain planning permission for air conditioning and external plant installations.

Thinking about installing an air conditioning unit? Contact AVA Home Design for advice on whether Permitted Development or a full planning application is the right route for your property.
