should be no problem. Certainly be ok if they are only just past the date. It's a best before date, but normally they won't start deteriorating for a long time after, depending on how they've been stored. I've got some bottles in the fridge that are 6 months past their date, but they're still fine.
Occasionally my husband comes home with a few bottles that the bar manager has been about to chuck out because of the sell-by date.
If they're no more than a couple of weeks or so over date, then they should be fine. Beyond that, they're unlikely to do you any harm, but they may not taste their best. By 'taste their best', I mean that you'd have to be a real connoiseur of beer to be able to tell.
