Hey thanks, I'll have a good look at all of this. The bolt products page and the video are fantastic.
I'm living more or less in the city and I know a few of the local developers here but they are busy with a new bouldering area.
Getting the materials seems pretty straight forward I just wanted to see if there was any good solid british advice out there
Sadly I don't know if I can get hold of glue-ins but the Petzl ones are pretty safe right? I hope so I've been falling on them for a few months :P
