The Tavistock and Portman NHS Trust's Gender Identity Development Service (GIDS) was at the centre of a decade-long safeguarding dispute that ended with its closure in 2023. Sonia Appleby, the Trust's named safeguarding professional, raised genuine concerns about the service's governance. Her employment tribunal victory against the Trust in 2021 was real, the failures it exposed were real, and they deserve to be understood clearly, because the same narrative has since been picked up and used to argue that gender-affirming care for young people is inherently dangerous. Those two things are not the same, and conflating them does harm.
What was GIDS and why does this matter now?
GIDS was the only NHS service in England and Wales providing specialist gender care to children and young people. At its peak it held thousands of referrals, with waiting times stretching to years. Whatever you think about how it operated, it was the place where trans and gender-diverse young people and their families had to go. When things went wrong there, they went wrong for that group of people, who had, in many cases, already been waiting years in distress to be seen.
The closure of GIDS in 2023, following the Cass Review, led to an almost complete collapse of NHS gender care for under-18s. The puberty blocker ban that followed, and the ongoing absence of a coherent replacement service, have caused measurable harm to young people and their families. Understanding the safeguarding dispute clearly matters because it is frequently cited to justify that harm.
Who is Sonia Appleby and what did she find?
Sonia Appleby held the statutory role of Named Nurse for Safeguarding Children at the Tavistock and Portman NHS Trust. Her job, in effect, was to make sure the Trust was protecting the children in its care. She was not an ideological opponent of gender-affirming care. She was a safeguarding professional doing the job she was employed to do.
From around 2017 onwards, Appleby raised concerns that children and young people attending GIDS were reporting concerns about their care, concerns that were not being properly heard, recorded, or addressed through the Trust's safeguarding processes. She was particularly worried that complaints from young people were being channelled back into the clinical team rather than handled through independent safeguarding routes. She raised this repeatedly, internally, through appropriate channels. Her concerns were, she said, consistently dismissed.
In 2020 she brought an employment tribunal claim, arguing that the Trust had subjected her to detriment for raising those concerns, in other words, that she had been treated badly for doing her job. The tribunal found in her favour in 2021. The Trust had subjected her to detriment by reason of her making protected disclosures. That is the legal term for blowing the whistle, and it is a serious finding.
What were the actual safeguarding failures?
The tribunal's findings describe governance failures: the siloing of concerns inside the clinical team, inadequate independent oversight, and a culture in which a named safeguarding professional felt unable to do her work without facing professional consequences. These are institutional failures about how complaints and concerns were managed, not findings that the clinical interventions GIDS provided were harmful in themselves.
To put it plainly: the problem identified was that when children or families had concerns, those concerns were not being heard through the right channels. That is a real problem. It is the kind of problem that can allow harm to continue unaddressed. It is also, unfortunately, a problem found across NHS services and institutions far more broadly, and it does not tell us whether the underlying care was right or wrong.
There were also concerns raised by some clinicians about the pace of assessment and about whether the service had sufficient multidisciplinary oversight for complex cases. Those concerns deserve to be taken seriously, too. But they are not the same as saying that puberty blockers or other gender-affirming interventions are dangerous, and the leap from one to the other is one that has been made repeatedly in public debate without justification.
How has this narrative been used, and misused?
Appleby's tribunal victory was real. The governance failures were real. But the narrative that grew around them, that GIDS was systematically harming children through its clinical work, that puberty blockers were being recklessly dispensed to vulnerable young people, that the whole project of gender-affirming care for minors is a safeguarding catastrophe, goes far beyond what the evidence supports. It was built by layering genuine institutional failures onto contested clinical questions, and presenting the whole thing as settled.
The Cass Review drew heavily on this atmosphere. It has since been widely discredited internationally, including by gender specialists who published detailed rebuttals. Its citation practices and selective use of evidence have been criticised by clinicians and researchers in multiple countries. And yet its findings, along with the safeguarding narrative, were used to justify the ban on puberty blockers on private prescription to trans young people in the UK, and then to influence policy in other countries.
Trans young people, the ones who had been waiting years for care, were the ones who paid the price for institutional governance failures they had no part in creating. That is not accountability, it is scapegoating.
What does genuine accountability look like?
Genuine accountability would have meant fixing the governance: creating proper independent safeguarding routes, ensuring children could raise concerns without those concerns being absorbed back into the clinical team, improving multidisciplinary oversight, and reducing the catastrophic waiting times that left young people in prolonged distress.
It would have meant asking: what do these young people and their families actually need, and how do we make sure they can get it safely?
Instead, the response was to close the service, ban the medication, and leave tens of thousands of young people with no pathway to care. That is not a safeguarding response; a safeguarding response puts the welfare of the children at the centre. Removing all access to care for gender-diverse young people does not do that.
I've heard from so many families over the years who have described what it is like to watch a young person deteriorate on a waiting list, knowing that the help they need exists but is being withheld. The harm from denial of care is not abstract. It shows up as depression, self-harm, and suicidality at rates that are well documented. Delay is not neutral. Withholding care is a decision, with consequences, and those consequences fall on real young people.
Can we hold both things at once?
Yes, and we have to. It is possible, necessary, in fact, to say all of the following at the same time.
Sonia Appleby did the right thing. She raised legitimate concerns through proper channels and was punished for it. That was wrong, and the tribunal was right to find in her favour. NHS services must have proper, independent safeguarding processes. Complaints and concerns from children must be heard outside the clinical team that is the subject of those concerns. Those are basic principles of good governance and they apply to every service, including gender services.
And: the response to those governance failures did not protect trans young people. It removed their care. The safeguarding discourse around GIDS was taken up by people who had been arguing against gender-affirming care for years, and used to give political cover to restrictions that went far beyond anything the evidence warranted. The children the safeguarding system is supposed to protect were the ones who lost out.
Holding both of those things is not a contradiction; it is what intellectual honesty requires.
What happened to the young people?
After GIDS closed, NHS England established two regional hubs, in London and in the North West, to begin a new service. The waiting lists remained extraordinarily long. Many young people who had been under GIDS found their care paused or ended. The private prescription route for puberty blockers was banned, so families who could have accessed care through private specialists lost that option too. NHS prescriptions became nearly impossible to obtain.
For many families, the only remaining option was to go abroad for care, to the Netherlands, to Belgium, to Spain, at significant financial and practical cost. Those who could not afford that had no pathway at all. The young people who could least afford private care or international travel, those from the most disadvantaged backgrounds, were the ones left with nothing.
That outcome was predictable, and it was predicted. It was not an accident. It was the foreseeable consequence of policy decisions made in the name of protecting children.
The honest summary
GIDS had real governance failures. Sonia Appleby was right to raise her concerns, and the Trust was wrong to treat her the way it did. Those facts should be on the record, clearly and without flinching.
The clinical and political response to those failures caused serious harm to gender-diverse young people, removed their access to care, and left a generation waiting with nowhere to go. That, too, should be on the record.
The safeguarding of trans young people means making sure they have access to affirming, well-governed, properly overseen care, not using the language of safeguarding to deny them care altogether. Anyone who uses the Tavistock story as an argument for the latter is not doing safeguarding. They are doing something else.
