Due to the UK being the Rothschilds playground, banks rejecting anything to do with Bitcoin & the general backwards thinking of UK society as a whole - it can be quite frustrating dealing with Bitcoin. However, do not despair, we are here. Scattered around. Plenty of miners too, of which I am also one.
If you're looking to sell BTC regularly I can recommend a UK based forum user by the name of Projects (
https://bitcointalk.org/index.php?topic=150537.0;topicseen) - I use him & he's completely reliable. Otherwise you can use bitbargain.co.uk or localbitcoins.com to find someone near you to deal with personally.
