No way, my first appointment at Charing Cross is due around May too!
I'm a bit late so you may have already found this, but this tumblr has some results from the main UK surgeons:
http://ftmtopsurgeryuk.tumblr.com/I went to a new patients workshop at Charing Cross in November - the main top surgeon they work with is Andrew Yelland, who seems to be by far the most experienced surgeon in the UK for male chest reconstruction. He's based in Brighton. His website, complete with before and afters:
http://www.transurgery.com/He's very highly rated, very experienced, and I'd say his results are hands down the best I've seen for the UK. Only downside is his waiting list is...I don't know how long, but I've heard 7/8 months. Might not be accurate, but if it is, it's well worth it imo - we're stuck with our chests for the rest of our lives. I have my heart set on him

The other surgeons you'll see listed in the tumblr. None of them have the experience Yelland does, so if you want the best chance of a good result, I don't know how I'd feel about them. There are a few others not listed, but most of them specialise in mastectomy for female identified people, and have little to no experience in male chest reconstruction.
I'm sure Charing Cross will be able to advise you on picking a surgeon when you get there, and they'll have all the information you need to be secure you're making the right choice (and bearing in mind the assessment process takes a while in itself, you'll have plenty of time to think it over). So try not to feel overwhelmed!
Personally, I wouldn't consider anyone other than Yelland (as long as I had a choice). Lots of info available about his practice on the web, lots of before and after shots that are consistently pretty damn good. It's difficult to find enough before and afters for the other surgeons to have much idea of what you're getting into - and often any information at all - so I wouldn't feel safe.

It's weird, when I first got on the waiting list medical transition was such a distant reality it didn't feel like it would ever happen. Now it seems so close I'm getting butterflies D:
Anyway, best of luck with all your stuff and stuff. Hope you're having a fabulous day

and that my fangirling over Yelland was at least slightly helpful.
