as a complete central heating layman, I've been arguing at work today about parts charging policies for boiler repairs (combis)
If an engineer diagnoses a fault and orders the relevant part, fits it and that part turns out not to be faulty, does he take out that part, and get his money back from the supplier then move on to the next part and do the same thing and so on, until the faults fixed?
Or, does every job get diagnosed right first time?
I've read so many times, of consumers paying for a PCB board, then for this then for that until finally the fault is located.
Who pays for not needed parts - the engineer or the customer?
