Hi Guys,
When I was in your position I joined the Milton Keynes Mountaineering Club who meet at Big Rock. There are normally club members there most days although our official night is Thursdays.
Look out for the T-shirts and just come and say hi or ask at desk and they should be able to point you towards one of us.

I have not had a problem finding someone to climb with since
