Laser and Electrolysis in London UK

I have been trying for ages to find a good reputable Electrolysis in London, England. Many seem to work at home or in very small practices. I want to make sure that i get the best treatment. It seems like it is much easier to find places to go in the USA.

Does anyone have any experience of Electrolysis in London and have any names for me?
I have managed to find someone to get some Gentlase done but really want to continue with electrolysis.

Any help would be greatly appreciated
