NHS vs Private Autism & ADHD Diagnosis in the UK: What You Need to Know
In the UK, thousands of families and adults are stuck waiting for neurodevelopmental assessments. For some, the NHS remains the only option; for others, private assessments offer a faster route to answers. But what’s the difference and how can you make an informed choice? (latest NHS data)
NHS Assessments
The NHS pathway is guided by NICE (National Institute for Health and Care Excellence) standards. Referrals are made through your GP or school SENCO, usually to CAMHS or adult neurodevelopmental services. (NICE) (NHS England guidance)
Pros:
Free and regulated
Integrated with NHS care pathways
Cons:
Waiting times of 2–5+ years
Limited flexibility for scheduling
Shorter appointments due to demand
Private Assessments
Private providers like Autism Services Group bridge the gap with faster, clinically valid assessments.
“Private doesn’t mean unregulated,” says Sarah Phelan. “We follow NICE guidance just as NHS teams do - the difference is time, access, and personalisation.”
Pros:
Shorter waiting times
More time per client
Holistic and individualised assessments
Cons:
Costs vary (£800–£1,500)
Quality varies — always check credentials

The Right to Choose (how it works)
Some NHS patients can access independent assessments through the Right to Choose pathway, which allows individuals to choose an approved external provider funded by the NHS.
“If cost is a barrier, Right to Choose is worth exploring,” Sarah notes. “It’s about choice, not privilege.”

Conclusion
There’s no one-size-fits-all route. For some, NHS assessments work best. For others, private pathways provide vital clarity sooner. What matters most is choosing a provider who uses validated tools, follows NICE guidance, and treats you with respect and care.
“A diagnosis isn’t the end,” says Sarah. “It’s the start of understanding yourself better — whichever path you take.”
