Gender Incongruence
What it is, what it is not, guidance for young people, parents and families, professionals, the NHS pathway following the 2024 independent review of gender services, legal aspects, and schools.
What is gender incongruence?
Gender incongruence is the experience of a persistent mismatch between a person's internal sense of gender and the sex they were assigned at birth. It is not a mental illness.
Classification — ICD-11 (2019)
In 2019, the World Health Organization removed gender incongruence from the mental health chapter of the International Classification of Diseases (ICD-11) and reclassified it under “Conditions related to sexual health.” This reflects the scientific consensus that gender incongruence is not a disorder to be treated, but a variation in human experience.
What causes distress?
Gender dysphoria — the distress that can arise from gender incongruence — is primarily caused not by the incongruence itself, but by unsupportive environments, misgendering, lack of access to care, and social rejection. When environments are accepting and affirming, distress reduces significantly.
Key terms
Gender incongruence
The experience itself. A neutral term describing the mismatch between internal gender identity and assigned sex at birth. Not a disorder.
Gender dysphoria
The distress arising from gender incongruence, particularly in unsupportive environments. The clinical term used in UK healthcare for accessing support.
Transgender / trans
An identity term used by many people whose gender identity differs from their assigned sex. Not all people with gender incongruence identify as trans.
Non-binary
Identifying as neither exclusively male nor female. Includes genderfluid, genderqueer, agender, and other identities outside the binary.
Social transition
Living as one's gender identity without medical intervention — changing name, pronouns, clothing, and presentation. Fully reversible. Evidence strongly supports this for improving wellbeing.
Medical transition
Hormone therapy and/or surgery. For adults and some young people following specialist assessment. Requires NHS referral or private pathway.
For young people
If you are a young person experiencing gender incongruence, your feelings are valid. You do not need to have everything figured out, and you do not need to be certain to deserve support.
Your feelings are real
- You do not need to prove your gender identity to anyone
- It is completely normal to be uncertain — exploring your identity takes time
- You are not broken, going through a phase, or seeking attention
- Your mental health matters now — not only after a diagnosis or when you are older
- You deserve support regardless of where you are in your journey
Getting support as a young person
- Mermaids — 0808 801 0400 Mon–Fri 9am–9pm
- Gendered Intelligence — youth groups, ages 8–25
- Young Stonewall — information for LGBTQIA+ young people
- Kooth — free anonymous online counselling 11–25
- Your GP — if you are 13–16+, you have the right to be seen confidentially without a parent present (Gillick competence)
- Your school counsellor — ask about confidentiality first
For parents & families
If your child has told you they are experiencing gender incongruence, you may be feeling love, concern, uncertainty, and worry all at once. All of those feelings are understandable. The most important thing you can do is listen and keep the door open.
Things that help
- Listen without immediately trying to fix or question
- Use your child's preferred name and pronouns — even while you process; it matters to them enormously
- Tell them they are still your child and you love them
- Take your own time to process — seek support for yourself
- Involve your child in decisions about their care
- Contact Mermaids or PFLAG for parent-specific support
Things to avoid
- Dismissing or minimising (“it's just a phase”)
- Attempting to change your child's gender identity in any way — this causes serious psychological harm
- Withdrawing love or connection conditional on identity
- Telling extended family without your child's permission
- Making your child feel responsible for your distress
- Pressing for certainty before your child is ready
Why Identity Validation Can Save Lives
The research evidence on why being seen, named, and affirmed is not just kind — it is clinically protective. Essential reading for families, professionals, and anyone supporting an LGBTQIA+ person.

Guidance for families navigating gender incongruence, including supporting your child at school and in healthcare.
genderedintelligence.co.uk →NHS pathway — updated following the 2024 independent review
- The evidence base for many interventions was found to be weaker than previously understood, and more research is needed
- A holistic, multidisciplinary approach — addressing mental health, neurodiversity, and social context alongside gender — is essential
- Many young people attending gender services had co-occurring mental health needs, autism, or other neurodevelopmental differences that were not always being adequately addressed
- Social transition in younger children should be approached with care, given its potential impact on psychological outcomes — though it remains supported for many young people
- Puberty blockers: the review found insufficient evidence to support their routine use outside of research settings for gender dysphoria
- The review emphasised the importance of follow-through care, family support, and not leaving young people without any support whilst waiting for assessment
For children & young people (England)
- GIDS closed in 2024. New NHS Regional Gender Services (RGS) are being established
- Referral via GP to regional services — check NHS England for current provision in your area
- New model emphasises holistic mental health assessment and support alongside any pathway
- Puberty blockers: NHS England has paused their routine use outside of research settings pending further evidence
- Social transition support continues to be available and recommended where appropriate
- NHS gender services →
For adults (18+)
- NHS adult gender services remain available — referral via GP
- Waiting times remain very long in most areas — often 3–5+ years
- Informed consent model is not yet standard across NHS adult services
- You have the right to change your NHS records (name, gender marker) without a GRC — ask your GP practice
- Wales: BCUHB provides gender services — ask your GP for the current pathway
- Independent review report: cass.independent-review.uk →
Private pathways
Private gender services offer faster access. Costs vary significantly. Key considerations:
- Private diagnosis is valid for most purposes including employment and school records
- Some GP practices will accept a private diagnosis to prescribe hormones via shared care — ask your GP
- GIRES TranzWiki lists verified UK providers: gires.org.uk
- Gender Construction Kit has clear guidance on UK transition pathways: genderkit.org.uk
- For young people: private providers are available but must follow clinical governance standards
- Be cautious of providers offering assessment and prescription without adequate psychological assessment. The 2024 independent review highlighted the importance of thorough holistic assessment before any clinical pathway.
- Mermaids and Gendered Intelligence can advise on reputable private providers for young people
Legal aspects of gender incongruence
Deed Poll — changing your name
- You can change your name by deed poll at any age (with parental consent under 16)
- Free to do yourself at gov.uk/change-name-deed-poll
- Allows you to update most records including NHS, DVLA, passport, and bank accounts
NHS records

- Some practices may need guidance — NHS guidance →
Gender Recognition Certificate (GRC)
- A GRC provides full legal recognition of acquired gender under the Gender Recognition Act 2004
- Not required for most daily purposes (passports, driving licence, NHS records)
- Required to change the gender marker on a birth certificate
- Process involves a Gender Recognition Panel and evidence of living in gender for 2+ years
- gov.uk guidance →
Passport & DVLA
- Passport: can be changed with a statutory declaration — GRC not required. gov.uk →
- DVLA driving licence: can be updated with a letter from your GP. GRC not required.
- For under-18s: name changes on official documents require parental consent
Schools & gender incongruence
Schools have legal duties under the Equality Act 2010 and specific guidance on supporting trans and gender-questioning pupils. This is a rapidly evolving area following government guidance updates in 2023.
What schools must do
- Protect all pupils from bullying, including transphobic bullying — this is a legal duty under the Equality Act 2010
- Respond to all reports of bullying promptly and effectively
- Make reasonable adjustments for pupils with protected characteristics
- Maintain confidentiality when a pupil comes out to a member of staff — do not disclose to parents without the pupil's consent unless there is a safeguarding concern
- Not discriminate against trans or gender-questioning pupils in access to education, facilities, or activities
Government guidance 2023 (England)
- DfE updated guidance on “Gender questioning children” (2023) sets out how schools should approach requests to socially transition
- Guidance recommends schools should not automatically agree to social transition without careful consideration and parental consultation in most cases
- Guidance is advisory — schools retain discretion and must act in the best interests of the pupil
- The guidance remains contested and subject to legal challenge
- Wales: Welsh Government has separate guidance — gov.wales →
PSHE & LGBT+ inclusive education
- Relationships and Sex Education (RSE) is statutory in England from age 11. Schools must ensure LGBT+ relationships are represented in an age-appropriate way
- Schools cannot opt out of including LGBT+ content in RSE
- Ofsted inspects for inclusive culture and effective response to bullying including homophobic and transphobic bullying
- Stonewall School Champions and Just Like Us provide school resources and training
- Just Like Us → | Stonewall schools →
Anti-bullying duties
- All schools must have an anti-bullying policy that specifically addresses homophobic, biphobic, and transphobic bullying
- Ofsted expects to see evidence of how schools prevent and respond to HBT bullying in inspection
- The Diana Award and Barnardo's provide anti-bullying resources for schools
- If a school fails to protect your child from bullying, you can complain to the headteacher, governors, and ultimately to Ofsted
For professionals — clinical guidance
Healthcare, education, and social care professionals need to understand the clinical and ethical landscape of gender incongruence, which has changed significantly in recent years.
- Gender incongruence is not a mental disorder — treat it accordingly
- Use the person's stated name and pronouns consistently — this is basic dignity
- Mental health assessment should be integrated with, not a barrier to, gender support
- Co-occurring neurodivergence is common — assess and support both in parallel
- Conversion practices are harmful and must not be attempted in any form
- For young people: involve families where appropriate but respect Gillick competence and confidentiality
- Post-2024 review: refer to current NHS England Regional Gender Service guidance
- RCPCH, BMA, and NHS England all have guidance on clinical responsibilities
