Commentary on Sections Section 13:  Powers of entry
64.Section 13 enables an authorised officer to enter, at any reasonable time, premises (excluding premises used wholly or mainly as a dwelling) in Wales if the officer has reasonable grounds to believe that an offence under section 2 has been committed in the area of the local authority, and the officer considers it necessary to enter the premises for the purpose of finding out whether such an offence has been committed.
65.This power to enter premises does not enable the authorised officer to enter by force.
66.If required, an authorised officer must, before entering the premises, show evidence of their authorisation.
