A couple of excerpts from HoC debate last year on the subject:

'As recently as 2009, the NHS’s sole gender identity development service at the Tavistock and Portman NHS Foundation Trust received fewer than 60 referrals for children and young people, and just 15 for adolescent girls. Since then, demand has surged. By 2016, over 1,700 children and young people a year were referred—a 34-fold increase. More than half were teenage girls. In 2022, more than 5,000 children and young people were referred to gender identity clinics, and almost three quarters were female.
Dr Cass also found that there was a lack of robust data on what happened to the 9,000 children who were treated by gender identity services between 2009 and 2020. Many went on to continue their treatment at adult clinics, and the University of York had been due to research the long-term consequences of treatment they received as children, so that we can properly support them through their journey into adulthood. It was expected to provide important insights into the clinic’s work, including how many patients de-transitioned and how many were also diagnosed with a mental health condition or an autism spectrum disorder.
This Government took the unprecedented step of changing the law to make it possible for adult gender clinics to share medical data with the university. All bar one of the adult gender clinics refused to co-operate with this vital research. To quote Dr Cass, that is “unacceptable”, but I would go even further: I think it is deplorable and a dereliction of their professional duty. I am pleased to update the House that following the publication of Dr Cass’s report, I have been informed that all seven clinical leads for the adult gender services now intend to fully participate in this important work.'

'What has emerged in the Cass review is a scandal. It is a scandal that children and young people are waiting far too long—often years—for care while their wellbeing deteriorates and their childhood slips away. It is scandalous that medical interventions have been made on the basis of shaky evidence. It is scandalous that, despite all that, some NHS providers refused to co-operate with Dr Cass’s review. Perhaps the worst scandal of all is that the toxicity of this discussion means that people have felt silenced, and it required investigative journalism to prompt the review to take place. This particularly vulnerable group of children and young people are at the wrong end of all the statistics for mental ill health, suicide and self-harm. '
'The refusal of adult gender services to share data on the long-term experience of patients is inexcusable—as the Secretary of State said, it is deplorable. The data does not belong to them; it belongs to the NHS and, crucially, to patients. I welcome their coming forward now, but how was this allowed to happen, and what accountability does she think would be appropriate?
This report must provide a watershed moment for the NHS’s gender identity services. Children’s healthcare should always be led by evidence and be in the best interests of children’s welfare. Dr Cass’s report has provided the basis on which to go forward'

Where is all the data that was promised then?
