As per above reply, I do my own trailer inspections as I have a building but don’t have a ramp or pit, so I contract out my pmi on the tractor units. DVSA were quite ok with this arrangement when I last got inspected, but I wouldn’t want to do an inspection on a vehicle without being able to get underneath it properly over a pit or lifts etc.
The guide to maintaining roadworthy ness is a good starting point, it says you should have hard standing, undercover and a method of inspecting the underside.
