I would say that for a Class I appliance, once the earth bond has been proved, then some sort of Insulation test is important.
However, if a full 500V Insulation Resistance test is inappropriate, many PAT instruments offer alternatives, such as a 250V Insulation test, or a Protective Conductor/Touch Current test (IEE CoP section 15.6)

Mike - I would strongly recommend that you get hold of the the new, 3rd edition of the IEE Code of Practice (it's got a purple cover).
A good study of this (most of which you should already know from the 2nd edition, having G&G 2377) should clear up any confusion regarding the inspection & testing of IT equipment.
