If you purchased VAT free goods during the VAT free period and collect & Pay for them after the VAT free period ends, you will be charged VAT on the goods.
However, didn’t Motability say they would cover this in their Q&A’s or one of the video’s and may have decided to be sly and hide it in Q2 AP’s? – I wouldn’t put it past them!
Yes, but as you say yu should be exempt.
