When I first realised what we were dealing with, I did what every parent does. I googled. I found a few NHS pages, a charity or two, some American resources that didn't quite map onto the UK system, and a lot of forum threads from parents who were just as lost as I was.
There wasn't a clear map. There still isn't, really. What there is depends heavily on where you live, what your local authority funds, how quickly your school's SENCO responds, and whether your area has a Speech and Language Therapy service that actually understands selective mutism — which, in my experience, is far from guaranteed.
This post is the map I wish I'd had. It won't tell you everything will be straightforward, because it won't be. But it'll tell you where to start, what to expect from each route, and where the real gaps are — so you can decide where to put your energy.
Start with the school, before you have a diagnosis
This is the first thing, and I can't say it loudly enough: do not wait for a diagnosis before talking to school. You do not need one. A diagnosis can take years to come through — if it comes at all — and your child needs support now, not eventually.
Go to the SENCO. Say your child has a fear of talking in certain situations and you'd like to understand what support the school can put in place. Ask for them to be placed on the SEN register at SEN Support level. Ask what gets written down.
The adjustments that make the most difference — removing pressure to speak, seating your child near their safe person, briefing specialist teachers — cost nothing and require no paperwork beyond goodwill and awareness. → How to Talk to Your Child's Teacher has the specific conversations to have and what to ask for.
The earlier you have this conversation, the better. Anxiety that goes unaddressed in a school setting compounds. A child who spends a year being called on to answer questions they can't answer is a child whose nervous system is learning, week by week, that school is not safe. Starting the conversation early doesn't mean catastrophising — it means not losing ground you don't need to lose.
The NHS route: realistic expectations
Your GP is the formal gateway. A referral from your GP can go to CAMHS (Child and Adolescent Mental Health Services) or to Speech and Language Therapy, depending on your area.
Here is what you need to know about that: waiting lists vary enormously. In some areas, SALT referrals for selective mutism are moving within a few months. In my part of London, we were looking at years. And when you do reach the front of a waiting list, the therapist you see may or may not have specific experience with SM — it's a relatively rare and specialist condition, and generalist SALT services often aren't trained in the frameworks that work.
CAMHS waitlists are even longer, and CAMHS is typically better placed to support co-occurring anxiety or other mental health presentations than to run SM-specific intervention directly.
None of this is the fault of the people working in those services. They are stretched to the point of breaking. But knowing the reality of the timeline means you can make informed decisions about what to do in the meantime — rather than putting everything on hold waiting for an appointment that may be eighteen months away.
Private support: if you can access it
If you have the budget, private Speech and Language Therapy is the most direct route to specialist SM support in the UK. The two services I've come across that are well-regarded specifically for selective mutism are Confident Children (Lucy Nathanson) and Selective Mutism Support (Anna Biavati-Smith). Both work with UK families and both know their stuff. Private SALT for SM typically runs to around £100–£150 per session, with packages often in the region of £1,000 or more. For many families that's simply not accessible, and there's no pretending otherwise.
If private support is within reach, it's worth it. If it isn't, you are not without options — you just need to take a slightly different route.
Educate yourself: genuinely the most powerful thing you can do
This is what I did. Not because I had any particular expertise, but because the professional support I needed either wasn't available or wasn't coming quickly enough, and my daughter needed help now.
I read everything I could find. Research papers, the clinical frameworks that SALT and occupational therapists use, lived experience accounts, books written by specialists and by parents. I talked to my sister, an Educational Psychologist. I talked to a psychotherapist friend and a SALT colleague. I stayed up past midnight more times than I want to count, because the school day was happening whether I was ready or not.
The books that are worth your time: The Selective Mutism Resource Manual by Maggie Johnson and Alison Wintgens is the clinical bible — dense, but comprehensive. Can I Tell You About Selective Mutism? by the same authors is much shorter and written for children and the people around them. Why Alice Doesn't Talk at School by Lucy Nathanson is a picture book, but Phoebe's teacher read it to her class and it transformed how the other children understood and responded to her — so don't underestimate it.
SMIRA — the Selective Mutism Information and Research Association — is the main UK charity and has a wealth of free resources, parent guides, and a Facebook group where you can talk to other parents going through the same thing.
Where the real gap is
The SALT waiting list is long. The therapists at the end of it may not specialise in SM. Private specialists exist but cost money most families don't have. Books give you the framework but not the application to your specific child, your specific school, your specific version of this.
That gap — between knowing what SM is and knowing what to actually do on Tuesday morning when your daughter won't eat her lunch because she can't ask for what she wants — is where most parents get stuck. It's where I got stuck.
It's also why I built SM Pocket Coach.
I'd spent months absorbing the frameworks — Maggie Johnson's sliding-in technique, sensory regulation approaches, anxiety ladders, the specific language that helps and the specific language that makes things worse. I'd talked to enough professionals to understand how the pieces fit together. And I wanted a way to use all of that, applied to Phoebe's specific situation, at 10pm on a Sunday when I'd just had a hard week and needed to think through what to try next.
The tool I built is trained on everything I learned. You tell it about your child — their age, their version of SM, what's happening at school, what you've already tried. It asks questions. It gives you something specific to work with, not generic advice from a page that doesn't know your child exists.
If you can only afford one month and then cancel, that's fine. Use it to ask the tool to explain the frameworks, suggest the books, walk you through the approaches that are most relevant to your child's presentation. Even that month will give you more practical grounding than most parents manage to find in six.
The shape of a starting plan
If I were starting from scratch today, this is where I'd put my energy, in order:
Talk to school now, diagnosis or not. Get something written down. Brief the SENCO. Read → How to Talk to Your Child's Teacher first.
Get your GP referral in early, even if the wait is long. The clock starts when you refer, not when you decide you're ready.
Lower pressure at home and school simultaneously. This is the single thing that moves the needle most in the early stages, and it requires no professional input. → Why Lowering Pressure Has to Come First explains the why.
Educate yourself. SMIRA, the Maggie Johnson book, Lucy Nathanson. Or ask SM Pocket Coach to do the education for you, applied to your child.
If private support is accessible, pursue it. Confident Children and Selective Mutism Support are the names I'd go to first.
And if you're doing all of this alone, in the evenings, while also holding down a job and a family and an anxiety of your own about where this goes — you're not failing. You're doing exactly what parents of SM children do. Which is figure it out, piece by piece, because nobody hands you a map.
Consider this a start of one.
