Property-specific advice

Cardiff air conditioning FAQs
Do Cardiff apartments allow external units?
Most Cardiff Bay developments permit them only in designated balcony or plant positions and require written consent from the freeholder or management company. Confirm before ordering equipment.
Is planning permission needed in Cardiff?
Domestic air source units are generally permitted development in Wales when siting and noise conditions are met, but conservation areas such as Pontcanna and listed properties need confirmation from Cardiff Council.
