Si,
I emailed them earlier this evening and they replied with a link on their site of how to change. Everything but the name they can change for free (address, contact number etc) but as for the name/owner it seems like Nominet have to do and its going to cost me £10.
I might give them a call as well though and try and sweet talk into them changing it for me (if they can!)
I knew when registering I shouldn't of put my name in but I was dumb enough to fill it out anyway.
Thanks for your help everyone
