In reply to Graeme G:
Cotswolds, S&R and GO O have limited ranges and the staff... well, you can imagine. Small independent retailers are best. Outside, Joe Browns / Climbers Shop, V12 are the ones that spring to mind. A few in Aviemore as well.
Joe Browns stock both Scrapa and La Sportiva. Not sure if they have the winter range available yet. Worth looking at the less prominent brands as well, if you can find stockists!
