Building Regulations Updates
Building Regulation guidance notes
The Approved Documents in the Building Regulations provide basic performance standards.
For standard new buildings the procedure to comply with these documents is normally straight forward.
However, to understand the requirements for non standard or existing buildings is sometimes difficult to work out, especially on items such as energy efficiency and on new innovations in design. We appreciate this and to help others, we are using our experience and knowledge to issue general guidance notes on a range of subjects, to explain how we interpret the requirements. We hope you find them useful.
