Starting secondary school with autism: a guide for parents (2026)
The transition from primary to secondary school is one of the most significant challenges many autistic children face. A new building, multiple teachers, a complex
If you are trying to decide between waiting for an NHS assessment or going private, this guide gives you the full picture — without sugar-coating either option. Both routes have genuine advantages and real drawbacks. What is right for your family depends on your child’s needs, your timeline, and your financial situation.
We will cover wait times, cost, quality, legal weight, and what to do if you cannot afford to go private but cannot afford to keep waiting either.
The single biggest practical difference between NHS and private autism assessment in 2026 is how long you wait.
| NHS assessment | Private assessment | |
| Wait time | 3–5+ years in most of England | 2–8 weeks |
| Cost | Free | £500–£2,200 |
| Legal weight of diagnosis | Full | Full (identical) |
| Report quality | Variable — often brief | Usually comprehensive |
| Feedback session | Sometimes included | Usually included |
| Referral needed | GP referral required | Self-refer directly |
| Follow-up support | Sometimes available via CAMHS | Limited — arranged separately |
| Geographic availability | Postcode lottery | UK-wide, including online options |
NHS waiting times for child autism assessments vary significantly by region. These are current estimates based on reported data and parent accounts as of early 2026:
| Region | Typical wait (children) | Notes |
| London (most boroughs) | 3–5 years | Significant variation by borough |
| South East England | 2–4 years | Better in some areas, worse in others |
| South West England | 2–4 years | Rural areas often longer |
| Midlands | 2–4 years | Urban areas slightly better |
| North West (Manchester etc.) | 2–4 years | Variable by CCG/ICB area |
| Yorkshire & Humber | 2–5 years | Some areas reporting 5+ years |
| North East England | 2–4 years | |
| Scotland | 2–5+ years | Some health boards 5+ years |
| Wales | 3–5 years | Among the longest in the UK |
| Northern Ireland | 3–6 years | Severe shortage of assessors |
These are estimates — actual waits vary significantly within regions and change over time. The only way to know the current wait in your area is to ask your GP or contact your local CAMHS service directly. Many families are shocked to discover the real figure.
Not necessarily — and the assumption that NHS equals higher quality is one of the most persistent misconceptions in this area.
NHS assessments are conducted by qualified clinicians using standardised tools, but so are good private assessments. The key variables that determine quality are:
In practice, NHS diagnostic reports are often brief — sometimes just two to four pages — because clinicians are working under enormous time pressure. A high-quality private assessment report is typically 15–30 pages, with specific recommendations for school, home, and any further referrals needed. That level of detail is far more useful for EHCP applications.
The quality of private assessments varies too. A poor private assessment is worse than a good NHS one. The answer is to choose a quality private provider carefully — not to assume NHS is automatically better.
Yes — completely. This is the question that matters most to most families, and the answer is unambiguous.
A private autism diagnosis carries exactly the same legal weight as an NHS one. It is accepted by:
The law refers to assessments by qualified clinicians — not NHS clinicians specifically. A private diagnosis from a registered psychologist or psychiatrist using validated tools is legally identical to an NHS one.

Being on an NHS waiting list does not mean doing nothing. There are several things you can pursue while you wait:
Schools do not need a formal diagnosis to provide support. Under the SEND Code of Practice, schools are required to identify and support children with special educational needs — a formal diagnosis is not a prerequisite. Talk to the SENCO and ask what additional support can be put in place based on your child’s observed needs.
DLA is based on need, not diagnosis. You can apply now using evidence of your child’s needs. A formal diagnosis significantly strengthens the claim, but it is not required to start the process.
Start recording your child’s daily challenges, support needs, and behaviours in detail. This diary will be invaluable whether you end up going through the NHS process or switching to private — and it strengthens any DLA application.
You can request an EHCP needs assessment without a formal diagnosis. The local authority must consider the request based on evidence of need. A detailed school report and your needs diary can support this request.
Local parent carer forums are independent groups of parents with SEND experience. They can advise on local NHS waiting times, what support is available locally, and what other families have found helpful. Find yours at nnpcf.org.uk.
Private assessment is not right for every family — but there are situations where it is almost always the better choice:
There are also situations where waiting makes sense:
The honest truth: for most families where a child is struggling, a private assessment is worth the cost. The financial return through DLA alone often covers the assessment fee within a few months. The difference a timely diagnosis makes to a child’s school experience, mental health, and family life is usually far greater than the cost.
Yes. Going private does not remove you from the NHS waiting list. Many families obtain a private diagnosis to access immediate support, while remaining on the NHS list for ongoing follow-up care, CAMHS support, and any co-occurring condition assessments (such as ADHD).
Once you have a private diagnosis, you can share it with your GP and any NHS services — it becomes part of your child’s medical record and should inform any future NHS care.
If I go private, do I lose my place on the NHS waiting list?
No. A private assessment is entirely separate from the NHS process. You can obtain a private diagnosis and remain on the NHS waiting list simultaneously. Many families do exactly this.
Can the NHS refuse to acknowledge a private diagnosis?
No lawfully. NHS services are required to take a private diagnosis into account. If you share a private diagnostic report with your GP or CAMHS, they should add it to your child’s NHS record and factor it into any care decisions.
Will a private assessment be faster if I pay more?
More expensive does not always mean faster. What a higher fee usually buys is a more comprehensive assessment with more clinicians — not necessarily a shorter wait. If turnaround time is urgent, ask providers directly about their current availability and whether expedited reporting is available.
What happens if I get a private diagnosis and the NHS later disagrees?
This is rare. A thorough private assessment using validated tools by a registered clinician produces a defensible diagnosis. In the very unlikely event that a later NHS assessment produces a different outcome, both reports would need to be considered. In practice, NHS clinicians do not routinely ‘overrule’ well-conducted private assessments.
My GP says a private diagnosis is not valid. What should I do?
This position is not supported by law. Ask your GP to explain their position in writing. If they maintain it, raise a formal complaint and seek advice from IPSEA (ipsea.org.uk) or a SEND solicitor.
