If an officer of a local housing authority enters premises under section 126(1) and finds one or more occupiers on the premises, the officer must produce evidence of the officer's identity and special authorisation to that occupier or (if there is more than one) to at least one of them.
An officer need not comply with subsection (1) if it is not reasonably practicable to do so.
Proceedings resulting from the exercise of the power under section 126(1) are not invalid merely because of a failure to comply with subsection (1).
In this section "special authorisation" has the same meaning as in section 126 (see subsection (10) of that section).
