Here's an interesting festival, being held in 5th /6th October.

It's being held in the spectacular Victoria Baths in Manchester (which won an award on the BBC TV Restoration programme a few years ago)
Some good brewers lined up (Magic Rock, Hard Knott, The Kernel and Summer Wine leap out at me!)
Port Street Beer House in Manchester and The Grove in Huddersfield will have a presence there I'm told.
Tickets can be bought from the website above (and printed out at home)
