If it's rented, first thing I'd do is look at the rental agreement, it
might be simply not allowed in the agreement. Regardless, since it is
rented changes to the wiring probably need to be done/checked by a
qualified electrician.
Why not just buy a plug-in RCD (as used for lawn mowers)? They also seem
to be cheaper.
At a guess, the laws around the rest of the system would depend on
whether this is a commercial or not. If it is commercial, it will need
to be PAT tested and since it's not bought as an item, that should
probably be done prior to use rather than as part of a yearly rounds.
Hope that helps,
Martyn
