Getting a diagnosis.
We need one before you book
UK law requires a diagnosis of gender dysphoria or gender incongruence, signed by an HCPC-registered psychologist or GMC-registered psychiatrist, before we can prescribe hormones. A GP letter on its own doesn't qualify.
No diagnosis yet?
We'll connect you with a specialist.
We don't carry out assessments ourselves — instead, we refer you to independent, government-registered psychologists and psychiatrists. Assessments are typically around £500, paid directly to the specialist. Once your diagnosis is confirmed, you're ready to book your initial appointment with us.

It still counts — we'll check it for you.
A diagnosis remains valid over time, even from years ago or another provider. We accept:
- Letters from HCPC-registered psychologists or GMC-registered psychiatrists
- Letters from another UK gender clinic or specialist, signed and dated
- Overseas reports, once translated into English (≈£80)
- But not GP letters, GenderGP letters, or anything unsigned or undated
