Building regulations guidance

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.
