Does any one know where i could gain permission to go shooting vermin like rats ,rabits in sutton in ashfield?

You need to ask farmers if they would allow you to shoot on their land. But when you go to ask do not carry your gun and be sure to be tidily dressed and very polite. The best idea is to become a member of a local shooting club as such clubs usually have been given access to land for hunting on from local farmers. Gun clubs often also have insurance and can give you training on hunting and safe shooting practices.
