Is there any building work that is exempt from Building Regulations?
Yes, but the work must comply with certain criteria. Works which fall into this category are extensions such as conservatories and porches, and detached buildings. They also include works to non-load-bearing walls which are not provided for fire-resisting purposes. (See “Domestic buildings exempt from Building Control”). However, even if Building Regulation approval is not needed, planning permission may still be required.
