But I’ve already got planning permission…

Building Regulation approval is a separate process from Planning permission, as they each relate to different legal requirements.

Planning Permission is primarily concerned with where a development is built, the impact on its surroundings and whether it is in keeping with its environment.

Building Regulations are more concerned with how a development is built, its structural strength and safety.

Many developments require Building Regulation Approval as well as Planning Permission. Additionally some developments that do not require Planning Permission will require Building Regulation Approval.
