I know I posted this subject already but I managed to contact someone who wrote an article on last years fair. At the end of the article he said this years was October 22nd. I contacted him to confirm this date along with the venue and he emailed me this back: NOTE THE CHANGE OF DATE.

Hi there mate
No it's on the 15th of October and there's a new venue, much bigger than the last one so Chas and Kymberley tell me.
Here's the new venue
It's at the Dick Collins hall in Redhill street, Regent's Park, Nw1 4DJ
If you need any more info just ask mate, start time I believe is from 1 30pm to 5 30 pm, no problem you asking, am going to get a preview up on the site 15rounds.com in the next few weeks mate.
