In reply to pipcollier:
You can get climbing shoes in both Crickhowell adventure (brecon) and cotswolds. They're about 200 yards apart at top end of town. Cotswolds has bigger selection but Crickhowell has quite a few on sale.
Nearest bouldering is buckland hill near bwlch. Search on ukc crag list for location. Or llangorse ropes centre indoors if it's wet. Otherwise Huntsham near symonds yat, where as someone else already posted you can drop into banana fingers.
