My experience with anything purchased in my local (UK) Apple store is that their preferred method is to email the reciept, as a PDF, to the specified email id. (In this case your father's).
I'm guessing that if an email id is not given a hardcopy receipt would be provided.
The Southampton store will probably still have an electronic copy of the purchase so you should ask them.
