Thanks for the corrections for my post saying the current gender change law requires surgery. It does not - I just checked, sorry to confuse anyone. I had thought it did - may be that was just considered when it was brought in in.
Wiki has a good summary which i put as much to remind me of the rules not anyone else...
"Since 4 April 2005, as per the Gender Recognition Act 2004, it is possible for transgender people to change their legal gender in the UK. Transgender people must present evidence to a Gender Recognition Panel, which considers their case and issues a Gender Recognition Certificate (GRC); they must have transitioned two years before a GRC is issued.
It is not a requirement for sex reassignment surgery to have taken place. However, such surgery will be accepted as part of the supporting evidence for a case where it has taken place.
There is formal approval of medical gender reassignment available either on the National Health Service (NHS) or privately. If the person's birth or adoption was registered in the United Kingdom, they may also be issued a new birth certificate after their details have been entered onto the Gender Recognition Register.
In contrast to some systems elsewhere in the world, the gender recognition process does not require applicants to be post-operative.
They need only to demonstrate to the Gender Recognition Panel that they have suffered gender dysphoria, have lived as "your new gender" for two years, and intend to continue doing so until death. "
