12th August 2026

3PB Barristers’ (3 Paper Buildings) expert planning and land-based Chancery barrister William Webster has written a succinct guide on the current planning concerns surrounding air conditioning units installed on the outside of existing buildings.
In his briefing, William discusses the hot topic of air conditioning, looking at how some authorities’ net-zero approaches makes it hard to fit ‘active cooling’ devices, and why the appearance of an air con unit could result in a visit from an enforcement officer!
William also offers practical advice around how owners can consult planning officers and look into their local plans before committing to installing air conditioning units.
