If a previous certificate exists, full property rewires for independent shops & retail usually starts by checking whether it still reflects reality. What we are really assessing is condition, not age. Public-liability insurance schedule shared before first invoice for compliance matters; the date on the board does not, by itself. That holds whether the property is owned, let or being sold.
The practical question on this job is 15-30 minute walk with the site or duty manager, and it is answered by testing rather than by opinion. In Barry that usually decides both the scope and the sequence of the visit. Two properties on the same street can differ on this entirely. Full property rewires for independent shops & retail is one of the more commonly misquoted jobs, largely because nobody tests before pricing it.
