Cheesemakers in UK/Ireland to visit?

[Tom Turophile / CheeseStud]

I'll be spending 10 days traversing England and Ireland in two months -- from London to Bath to Liverpool to Wales to Dublin to Belfast. 

Are there any cheesemaking areas or makers that I could visit?  Wensleydale is too far north, and Caerphilly is out of the way.

Here's a good resource that I need to comb through: http://www.britishcheese.com/
