Building Regulations Approval
Most structural work that you do to your property will require Building Regulations Approval. This helps to ensure that the work is carried out in accordance with the latest Building Regulation requirements and in the event of you selling your property, it also proves to the surveyor that any alterations you have made have been done properly.
You can either make a Full Plans Application or submit a Building Notice.
