Have a look at:

This is the site for the RAF GSA gliding club. It's military and is used mainly for skydiving and gliding, but is kept as a reserve field for the RAF.
The club seem friendly, and I intend to fly with them when I'm over in feb.
But if it's for non aviation use, then I wouldn't hold out much hope.
That's the only GA size strip that I know of..
