Sorry if I'm too late to the game but I'm part of a community gaming club based in Newton Abbot in Devon that runs regular
40k games and tournaments.
The community is called Terra Games LTD, you can find us on Facebook.
The community runs regular tournaments, painting evening and we always game on a Sunday. We also do Magic the Gathering, D&D and other table top games. Terra Games also stocks
40k models and can order from Games Workshop directly
