Scotland's good for agates, bloke sells them on Ebay probably cheaper than driving there. His website www.agatesofscotland.co.uk/

You can get Cotham marble in Watchett. near Minehead. Picwww.fossilbeach.co.uk/Templates/fossils/cotham_marble/cotham%20marble4.html Don't know how available it is from Bristol as Cotham is a very Built up area.

Somerset is good for geodes they call them field potatoes! Why I don't know. Beaches are a good source of material anything that isn't a uniform grey colour. Links. Mostly fossils. But some bits and pieces.

Alternatively google geology groups UK most of them will be able to tell you what's available locally.

I go to LLantwit Major mostly for devils toenails
and the occasional ammonite
I'm pretty new to this myself so I mostly go and have a look even if you don't find anything the day out's good.
