Hyde Park Source (I first learned of permaculture back in 1997 through meeting Andy Goldring of the Permaculture Association when starting HP Source).
I also did my first PDC taught by Andy, Niels Corfield, Joanna Dornan and others in Leeds in 1997, and there will be another PDC coming up in the spring I expect. Go to the Permaculture Association website to find courses.
www.GeoffLawton.com is a great source of videos. I especially like the cell grazing, fishponds and biogas videos. You'll also find links and information there about any upcoming online PDCs.
Back again to the Permaculture Association - the best way of getting a copy of Permaculture, A Designer's Manual in the UK.
I've found some really useful articles and information on www.internationalpermaculture.com:
