Not sure what genres you're in to and where you're located in the UK MDC, but I beg to differ, the UK is and has always had a thriving underground dance music scene - we embraced electronic music and gave the world all forms of dance music, let's not forget that
If you want big, well known clubs, one for a start is Fabric, even Ministry Of Sound I'd say. But the best stuff is the small, underground places, bubbling up all over the UK, just need to get involved. And in terms of festivals, there's a huge choice of dance music festival all over the country.
I really can't fathom out your post, there are 100's of nights going on all over, both urban and countryside. I live in the sticks and there are loads of free parties tucked out the way plus a v popular D&B night for example, bringing down the likes of Hazard, N.Blackmarket, Fabio, Majestic... etc etc.
