The UK government has clarified the planning and permitted development rules that apply to domestic air conditioning installations, helping households understand when fitting an air conditioner counts as permitted development and when full planning permission is required.

Issued via MHCLG, the guidance addresses the practical boundaries consumers need to know before installing a split system at home — including where outdoor condensers can be sited and when noise or visual impact can trigger a planning application.

For most homeowners weighing a wall-mounted split system, the takeaway is to check siting and noise limits before fitting, and to use a vetted installer who understands the local rules. Stockool's installer-matching service connects buyers with local engineers who fit to standard.
