The Epic-UK events calander is here -
http://epic-uk.co.uk/wp/event-calendar/What with Covid there's only a few events in the latter part of this year.
The calender for next year hasn't gone up yet (they only have the current year displaying) but January normally is when the Winter Warmer tournament runs in Bristol. I don't know if anything is on in Feb so that may be the better of the two months? Though the two locations are so far apart there might not be much or any cross over of antendees in Jan in any case.
