UNG, I agree, ISITEE is a better way forward...however, the sticker-jockeys can't extend to ISITEE...at 50p a go, how can you expect a proper service, especially for any appliance that doesn't simply plug in?
There is absolutely no reason why they shouldn't inspect and test all appliances no matter how they are connected if that is what they are contracted to do
Of course, there is the argument that fixed wiring is beyond PAT...but then, we have appliances that bridge the gap.
Fixed wiring comes under the EICR, fixed appliances do not and have never been considered to be part of the fixed wiring installation so there is no real and valid argument they are appliances and should be inspected, tested and recorded as such by the company carrying out the PAT
