Planning and building control
Building regulations applications and planning permission in Swansea are handled by Swansea Council. Most internal refits fall under permitted development, but new electrical circuits, structural openings, boiler installations and anything affecting a party wall need notification or sign-off before the work is signed off as compliant.
Always check whether your property sits inside a conservation area or has an Article 4 direction — both remove permitted development rights that most homeowners assume they have.
