Hi Liz, I know you're focused on the UK and Europe, but I traveled to Bangkok, Tfor gender for my confirmation surgery (GCS) at the Preecha Aesthetic Institute (PAI). A community member, Bobbie, generously covered my bottom surgery, and the clinic donated my facial feminization surgery (FFS) and several other procedures (which I didn't learn would go ahead until after I arrived), so I only paid for my airfare. Bobbie had done extensive research and could have chosen any surgeon worldwide, and she chose PAI for her own surgery. She offered me either the equivalent funds to use elsewhere or to proceed at PAI if I covered my flights. I chose PAI.
Even without those donations, my total cost in Bangkok would have been lower than comparable quotes in the US or UK, even after flights and lodging. My care was excellent from start to finish: clear pre-operative communication, an experienced surgical team, modern private hospitals, and attentive aftercare. If you're open to options beyond Europe, PAI is worth adding to your shortlist. If you contact them, ask for Jesse Niwat. Dr. Burin performed my bottom surgery, and Dr. Sutin performed my FFS.
My strongest recommendation is simple: knowing everything I know now, I would choose PAI again, even if I had to pay for everything myself.
