In addition to the two above, there is one at Cosby golf club that is available for non-members.
Interestingly the two pros at the Leicester Golf Centre in Oadby, Anders Mankert and Tom James, were both previously attached to Cosby.
Tom was a junior member at my club years ago. I played with him on the day he won our club championship when he was still a teenager.
If you want a basic range without any bells and whistles playing from mats then Cosby (my club) offers the best value. If though you require trackman or similar then Oadby and Kilworth Springs have that though at a significant cost. Whetstone is as cheap as chips but is open air and is half matts and half grass
