Hair transplant help!

Hi, I havent been on here for a while, I started using regaine and proscar after taking advice from this forum and its been working well. Ive been using it for well over a year now. I could see i was starting to lose the whole of the top but since using these im pretty sure its stopped it. Im now considering a transplant but don't know where to start. Are there any surgeons in the UK that are recommended? I'm not going into this at a spare of the moment thing, Im willing to travel to have it done and would like any recomendations so i could contact them with pictures etc and just get some general advice.

I'll attach some pictures and thanks in advance for any help.
