Depends where you are in Surrey, if you register (free) you can tell us. I live in Lightwater on the border of Surrey/Hants, so i go to the Collar and Lead Club in Farborough which has been great so far. There is a site, www.obedienceuk.co.uk (I think?), if it doesn't work, try google for it, they have a list of clubs in all areas
Good luck!
