Pre-application advice
If you would like some advice, or require more specialist information before you apply for planning permission, we can provide this through our pre-application advice service.
Certain types of building works may need building regulations approval (this could be as well as planning permission, or in some cases even if the works do not require planning permission).
You can contact our Planning Department if you have any queries.
You can also find out about the planning policy we follow when making decisions about planning applications.
