In reply to NeilMac: you could go online, it will be way cheaper, and probably quicker too. I've not got any online yet, but will try for my next batch as I am not impressed with the price my local framing shop charge me.
Thanks Dan. I've used picturelizard and Frith & Co (who are very good value - recommend if you're looking yourself) but both use couriers for orders over 1kg whose depots are 15/19 miles from me so missed deliveries are very inconvenient! Even the guys in Calumet didn't know of anywhere relatively local so I guess I've not got a choice!
