Approved documents

Practical guidance on how to comply with the Building Regulations is provided within 'Approved documents'.

As guidance is reviewed and changes made we will publish separate Approved Documents.

Each document contains:

  • guidance on the performance expected of materials and building work to comply with the Building Regulations
  • examples and solutions on how to achieve compliance for some building situations.

There is no obligation to adopt a particular solution contained within the Approved Documents. Re-designed Approved Documents for Wales replace those issued by HM Government. The re-designed Approved Documents for Wales will take effect from 03 April 2017. 

The Approved Documents held on this website are the current versions.

Archived versions of previous Approved Documents relating to Wales since 1st January 2012 can be found on the following link:
