Personally i wouldn't thought so unless you sort it out with them first although they would probably start asking questions like why you want to do this?.The only time i have heard of the post office holding on to anyones maill is if you tell them that you are going on holiday & can they keep your mail until you come back.
i heard from someone that u can do this but to be honest with u, if it is a regular occurence they may ask u to order a PO Box to store mail for collection
