Standard NHS
Your GP refers you to the local NHS service. Free, but demand has vastly outstripped capacity — waits of two years or more are common in many areas, and considerably longer in some. It remains the default route across all four nations.
ADHD Meaning / Assessment (UK)
uk pathwaysGetting assessed in the UK.
Waiting lists in parts of the UK now run to years, and most people never hear that there's more than one route. There are three — and one of them is an NHS right that many GPs don't mention.

Informational — not a diagnosis
01 — it starts with the gp
The referral.
Every route begins the same way: a GP appointment. Assessment for ADHD in the UK is carried out by a specialist — a psychiatrist or a suitably qualified specialist team — and your GP's job is to refer you, not to diagnose you. NICE guideline NG87 is the national standard that shapes how this should work.
It helps enormously to arrive prepared: specific everyday examples rather than labels, evidence from childhood if you have any (school reports are gold), and a note of how symptoms affect work, home and relationships. Our appointment prep tool was built for exactly this conversation.
02 — the three routes
Three ways through.
NHS Right to Choose
England only. A legal right, in place since 2018, to choose which provider takes your first outpatient appointment — including approved independent providers holding NHS contracts. Still NHS-funded, so free to you, and often substantially faster.
Private
Fastest, often within weeks, but you pay. Reported costs vary widely by provider and by what's included — commonly quoted ranges run from several hundred to a couple of thousand pounds. Check what the fee covers before booking.
about Right to Choose
It applies in England only, since NHS services are devolved — Scotland, Wales and Northern Ireland have their own arrangements. You need to be registered with an English GP. Some Integrated Care Boards have introduced local restrictions, so it is worth checking your own area's position before you ask. ADHD UK maintains a free postcode tool with current provider waiting times — far more reliable than any number we could print here.
03 — after the assessment
Diagnosis isn't the last step.
Two things catch people out. First, if you're prescribed medication, there's a titration period where dose is adjusted and monitored — and some providers have a separate queue for it, so a diagnosis date isn't a treatment date. Second, ongoing prescribing is often handed back to your GP under a shared care agreement; GPs aren't obliged to enter one, and some decline, so it's worth asking early.
A private diagnosis doesn't automatically transfer to NHS prescribing either — that also depends on shared care. And note that UK ADHD medication supply has been disrupted at points since 2023, which can affect timelines. None of this should put you off; it's just better known in advance than discovered late.
quick answers
UK assessment questions.
It varies enormously by area and changes constantly. Waits of two years or more are common in many parts of the UK, with some regions considerably longer. Because it's a postcode lottery, check current local figures rather than relying on a national average.
It's a legal right in England, in place since 2018, to choose which provider handles your first outpatient appointment — including approved independent providers with NHS contracts. It stays NHS-funded and free to you, and often has shorter waits than the local trust.
No. NHS services are devolved, so Right to Choose applies in England only. Scotland, Wales and Northern Ireland have separate arrangements. You also need to be registered with an English GP practice.
Reported costs vary widely by provider and by what's included, with commonly quoted figures ranging from several hundred to a couple of thousand pounds. Always confirm exactly what the fee covers — particularly whether follow-ups and titration are included.
Not automatically. Ongoing prescribing usually depends on a shared care agreement between your GP and the specialist, and GPs are not obliged to enter one. It's worth asking your practice about their policy before committing to a private route.

Where this comes from.
Which criteria will they use?
UK services may work from either system. The WHO’s ICD-11 (in effect since 2022) renamed the old hyperkinetic disorder to ADHD and brought it closer to the DSM. The older ICD-10 was stricter: its hyperkinetic disorder roughly matched only the combined presentation, so someone with mainly inattentive symptoms could fall outside it.
NICE guideline NG87 is what most NHS services actually follow for the care pathway. If you were assessed years ago and told you didn’t meet criteria, it is worth knowing the framework itself has changed.
