Hi, I'm British and have some bad news (don't take my word for it though, you should ask others as well as I'm just one person): it would take a long time for you to get this surgery on the NHS even if you moved to the UK now, as you'd have to be referred to a surgeon first (by an orthodontist), then wait to be seen - that process itself can take a few months - and if they decide you're eligible for surgery according to their criteria, you would be put on a waiting list and it would take at least another several months before it would be your turn to get the surgery. So even if all goes well, you're not going to get surgery any time soon on the NHS, plus you don't get to choose your surgeon and would have little control over what they do. I'm part of a Facebook group for jaw surgery patients in the UK, can give you details in a private message if you want and maybe other group members can give you more information. In short, it's amazing that people can get this surgery free on the NHS, on the other hand the process is slow and you don't have much say in your treatment. For example, there are people in the group that have been waiting to start orthodontic treatment for over two years.
