Can the attachment of the gland and banjo happen at the appliance and not at the consumer unit ?
 
Even if you have a dedicated cpc in the armoured cable, you need to ensure the armour itself is earthed, just in case, say, someone sticks a spade through it.
 
The use of banjo's or earth nuts and flying leads at one end is an absolute minimum. The use at both ends is standard practice, there are exceptions, but generally that is what i would expect to see on SWA cable installations
 
i would disagree with the banjospart of the above though Eng 54, IMO, if the gland is tightened hard upto say a galv glandplate, then i reall dont see what a bajo will add to that. If the surface is painted/coated, then a banjo is required: either A) tapped to the steel, which is then earthed itself, B) bolted with a flylead attached to the earthing terminal

Gland plates are exactly one of the reasons to use a banjo or other means of flying earth lead. You cannot rely on the screwed gland plate, to provide suitable ongoing earthing provision...

I assume said contractor is part of a Part P scheme (NICEIC, Napit, few others..) in which case complain to them. They'll investigate (in theory)...
