As a PP mentioned, there was lots of campaigning, that campaigning is still ongoing to make it easier, though as OP, it doesn't seem that onerous to me. I think current GRCs could be symbolic (or done away with really) and the GRA should be repealed.
This is from earlier this year. I tried to comment on it at the time in relation to single-sex spaces but couldn't see anywhere to do it.
"...Transgender people in the UK do not need the certificate to access women’s services or single-sex spaces, or to change the gender on their passport or driving licence.
The process of getting a GRC in the UK has been described by campaigners as intrusive and over-complicated. Danielle found the system had a lot of unnecessary hurdles and has called for a complete overhaul....
She said: “When I got the letter of diagnosis, I applied. I had to have two medical letters, two years worth of evidence that I am living as I say I am, like utility bills and wage slips. I had to get a statutory declaration witnessed by a solicitor, saying that the transition would be for life. That was in person.”
After submitting her case, Danielle was hopeful but sceptical of the outcome. She said: “I know Gender Recognition Certificates have been rejected for the most ridiculous reasons. I knew there would be a long wait. If there’s one thing transitioning teaches you is that there’s lots of waiting.”
The outcome of Gender Recognition Certificates are decided by the Gender Recognition Panel, part of the HM Courts and Tribunals Service.
In August, Danielle heard her application was refused as her diagnosis letter wasn’t signed off by the right kind of practitioner. She added: “If a doctor psychologist from an NHS gender clinic isn’t the right type of practitioner then I don’t know who is. I went back to the gender clinic and told them what had happened. The letter was then co-signed by the lead clinician, who I have never met.”
The application was resubmitted and Danielle was notified a hearing was to take place on January 12. Three days later, she found out that it had been accepted and her GRC would be posted in the next 20 days.
She said: “I didn’t trust the system at all. After the anticipation and the frustration, I just wanted it in my hands. On the date it arrived, it was just a relief.”
She said the certificate makes ‘zero difference’ to her day-to-day life: “It doesn’t change who I am. I already know who I am, I don’t need a piece of paper to tell me that.
“My biggest fear was that I would die and the death would be registered as male. A lot of people say who cares when you’re dead? It matters to me, and while I’m living I can control it. I can’t control it once I’m gone. That’s the biggest reason I really wanted this. As I don’t think there’s going to be a wedding any time soon!...."
