Creffields. Based in Reading but will offer free delivery to Sussex and Kent if the order is big enough. I think I paid about £38 a sheet for BB last time.
Bet that was a long time ago. That or you ordered a boat load!
Plywood prices have shot up recently. £75 including VAT delivered for small quantities of 18mm BB/B ply isn't that unrepresentative. Hunt around and you might get it for £65 or £70, but if you're happy with the quality and service you're currently getting then it may not be worth the risk. There are plenty of yards who really don't look after their plywood as well as they should, it's often badly stored which can cause bows and ripples, or the edges get chipped, or there are scuffs on the faces, or it was dodgy quality in the first place with excessive thickness variation or too many voids.
You can always trim a bit from material prices if you spend long enough shopping around, but there's often a cost to that strategy in terms of quality and convenience.
