welcome to APAT pal
The UK championship next saturday is sold out. You can turn up dead early and get on the alternates list though. A warning though, only one player got a seat this way in the last one at Walsall.
If you live in/near manchester there is also the regional event the following saturday. Ring up the casino beforehand to book your seat as manchester regionals are over subscribed.
Also, take a bit of time to read the website and previous forum posts. This should answer any further questions you have.
