Thankfully in my area there are two stations that I regularly listen to, which aren't part of Bauer or Global (the two big chains in the UK), one of them being your standard community radio station and the other being a station for proper electronic dance music.
You've gotta support your local stations, even if it's just by listening to them. If you don't then all the local stuff will just disappear.
@renbymon We've got a community station in Derby, but it's online only. I would be tempted to fund them to go FM, if it's solely the money that's holding them back.
