In reply to JJL:
If you're on Facebook, join the "Carpenters & Joiners talk" group, or the "Builders Talk Group", There will be someone on there who can point you in the right direction.
If you aren't too bothered about picking out your own boards then what about ordering a delivery from somewhere like John Boddys in North Yorkshire?
You're always better planing your own timber, cuts the price down massively,I buy American white oak for £23 Cu/ft, a little more for Beech
