Building Act 1984

7 Compliance or non-compliance with approved documents

(1) A failure on the part of a person to comply with an approved document does not of itself render him liable to any civil or criminal proceedings ; but if, in any proceedings whether civil or criminal, it is alleged that a person has at any time contravened a provision of building regulations—

(a) a failure to comply with a document that at that time was approved for the purposes of that provision may be relied upon as tending to establish liability, and

(b) proof of compliance with such a document may be relied on as tending to negative liability.

(2) In any proceedings, whether civil or criminal—

(a) a document purporting to be a notice issued as mentioned in section 6(3) above shall be taken to be such a notice unless the contrary is proved, and

(b) a document that appears to the court to be the approved document to which such a notice refers shall be taken to be that approved document unless the contrary is proved.
