Hi There, having looked up the requirements for a transportable unit, i cannot understand the fuss..... Nothing hard to comply with at all. A front end "S" type rcd so all circuits are protected and then standard rcd protection for finals. What is the problem or "onerous" about that?? SWA to a an enclosure with the front end rcd in it, then whatever you like to an ordinary CU, oh and you might have to TT it as no TNCS allowed.
