In this paragraph I am talking in general terms and am not talking about the IOC.
Often it's because the V765 man within some clubs has let the power go to his head and has created so many unnecessary hoops for the applicant to jump through, requiring such petty points of detail about the vehicle, far and away beyond what Swansea actually require to process a V765, merely to make his post as vehicle verifier feel ever so important to himself. And then he often has the front to charge a fee of several hundred pounds merely to look at a photo, sign a form and apply a rubber stamp.
If any club's V765 verifier is worth his salt, he should be able to tell at a glance if the vehicle & application in front of him is correct or not for what is being requested. Certainly there is no reason why any inspection should take longer than half an hour, nor any official dating letter take longer than the same time scale to write. Rubber stamping of a photocopied page from a County Council Vehicle Registration Ledger? How long does it take to get your stamp out of its box? Of the V765 form itself, that takes no longer than a couple of minutes to complete. What's a generous hour's pay? £25?
