What we do
The gender identity clinic is the largest and oldest gender clinic in the UK, dating back to 1966. We accept referrals from all over the UK for people with issues related to gender.
We are a multi-disciplinary administrative and clinical team, including psychologists, psychiatrists, endocrinologists and speech and language therapists. We work together in order to provide holistic gender care, focusing on the biological/medical, psychological and social aspects of gender.
What to expect
In order to assess your individual needs and goals, we ask a number of questions about your background, current circumstances and future plans. The purpose of these questions is to help us gain a clear idea of how we can help you.
Based on your individual needs and circumstances your clinician will explore with you what may happen next with your gender care. For example, if you would like to, but have not yet made a social gender role transition, they may explore with you any possible obstacles in your way and help you consider ways to address these.
Additionally, in order to support you through the transition process, clinicians may discuss with you the possibility of referrals to other services within the GIC or local to you (which your GIC clinician can ask your GP to make).
We will keep your GP up-to-date about your progression through the clinic and you will be copied into the reports sent. Your clinician will also be able to offer you information and advice about other forms of support that you may find helpful as you move along your gender care pathway.
Endocrine service
For urgent advice relating to hormone therapy we have a GP hormone advice phoneline: 020 8938 7369.
This is for GPs and other healthcare professionals. If we do not answer the phone call, please leave a message. We aim to respond within 48 hours.
For routine queries and matters relating to hormone therapy please contact us by email at gic.endo@tavi-port.nhs.uk. For patients under our care or previously under our care, we can review hormone therapy monitoring results and provide advice and support regarding hormonal therapies. Please also browse our endocrine webpage for more information and our clinical guidance.

Waiting times
There is a high demand for appointments, which is common across other gender identity clinics around the UK.
Changes to what data we publish
27 November 2025
We would like to apologise for the delay in updating our waiting list data over the past few months. We have been working with patients, clinicians and commissioners to hear what information they would like to see and find useful, to better represent the gender identity clinic on this page.
Changes include:
- Reporting on the number of first assessments completed (as opposed to offered)
- How many patients have been discharged following a completion of their treatment
- The number of appointments attended by patients across all of our gender services
- Publishing data of how many patients ‘did not attend’ their appointments.
We are improving our internal admin processes and will ensure this data is kept up to date regularly.
