I know you're probably only looking for UK input, but figured I'd share for anyone who stumbles across this looking for a US perspective. Caveat, I live in a very progressive city with a lot of healthcare options around, I have insurance coverage with no trans exclusions, and I had piles of money saved specifically to use for transitioning.
- Summer 2014, came out and socially transitioned
- October 2014, started seeing a therapist and didn't get along, fired her
- 27 November 2014, 1st clinic appointment to start HRT w/ bloodwork
- 5 December 2014, started HRT
- End of December 2014, started seeing new therapist for top surgery referrals
- February 2015, top surgery consult
- March 2015, name and gender marker legally changed and updated on all documents
- 21 April 2015, top surgery
- December 2015, got referrals for bottom surgery
- 24 February 2016, bottom surgery consult
- Summer 2016, bottom surgery? Hopefully?
