Even though VAT only applies on cars handed over after July Motability price fix APs at the point of an application. Since Motabilty don’t know which cars will be handed over they may have decided to increase all AP from 1st April to ensure they are not covering a large VAT bill Or to put it another way, it’s more likely a large increase this time, and very little in July.
Surely you mean all orders after July will be subject to VAT, any orders prior to this date are non VAT payable by customer?
