If you'd like to support some trans people in the UK I'd recommend donating to Trans Aid Cymru.
They do fantastic work, helping trans, nonbinary and intersex people in Wales with day to day expenses as well as transition related stuff.
and if you're trans/nonbinary/intersex and live in Wales you can request grants for basically any reason! also want to recommend Trans Tech Tent for people who need computer/tech repairs in South Wales if you know of any other UK based groups like these feel free to add to this post
