Planning and building regulations
Your local authority is responsible for considering applications for planning permission, building regulations consent, and some other consents that you might need - for example where there is a Tree Preservation Order.
It can provide guidance on the circumstances in which you're likely to require these consents, and advice on the application process. Pre-application contact and discussion is also important, so that the required information is provided with the application, and a decision can be made within government time limits - otherwise the application may have to be refused.
You should check whether you need planning permission from your local authority before beginning building work or changing a building's use.
Building work often has to conform to building regulations, regardless of whether planning permission is needed. Your local authority has responsibilities for monitoring construction work and carrying out inspections to check compliance with these rules.
It's a good idea to seek guidance from your local authority before commencing work if you're unclear about any of the requirements.
