Open six private ADHD clinic websites and you will get six different answers, and at least two will begin with the word "from". A price that starts somewhere and stops nowhere.
The real difficulty is not that private ADHD assessment is expensive. It is that almost nobody publishes the whole bill. The assessment fee is the headline; the reviews, the prescription and the medication arrive later, one at a time, after you have already paid.
How Much Does a Private ADHD Assessment Cost?
At Private ADHD, an adult assessment is £650 and a child or adolescent assessment is £1,395.
Across the wider market, the most useful published survey comes from myTribe Insurance, which contacted 401 private ADHD clinics in June 2024. It found an average of £1,200 for adults and £1,361 for children, with follow-up consultations averaging £173. Regional averages ran from £936 for an adult assessment in Northern Ireland to £1,525 for a child assessment in Yorkshire and the Humber.
Treat that for what it is. myTribe is an insurance comparison business rather than a regulator, and it recorded advertised prices rather than what people actually paid. It is still the only UK survey we can find that names its method, its sample and its date.
What the Fee Includes
- The pre-assessment paperwork, including a medical history and a standardised rating scale
- A structured consultation with a GMC-registered psychiatrist, by video or in person
- A written diagnostic report stating what the clinician found, and why
- A letter to your GP so your NHS record reflects the outcome
What the Fee Does Not Include
- Medication, which is dispensed and charged separately by a pharmacy
- Titration reviews, ongoing prescribing, therapy or a workplace report
And one thing worth stating plainly: the fee does not buy a diagnosis. You are paying for an expert opinion, and sometimes that opinion is that you do not have ADHD.
The Cost People Miss: Titration
If you are diagnosed and you choose medication, the assessment fee turns out to be the smaller number.
ADHD medication is started low and increased in steps until it works without unacceptable side effects. That process is called titration. NICE guidance is clear that it must be supervised by a clinician with ADHD expertise, with regular review and physical health monitoring throughout.
Our titration reviews are £245 per month, and titration typically runs three to six months depending on how quickly you respond. That is a real cost, and it is the one most pricing pages leave off.
Medication and the Handover to Your GP
Once your dose is stable, the aim is usually to move prescribing to your GP under a shared care agreement. That is cheaper for you and it is how NICE expects the pathway to work.
Your GP is not obliged to accept shared care, and some decline. If that happens you can continue privately, which means an ongoing monthly prescribing fee rather than an NHS prescription charge.
What If You Are Not Diagnosed?
You still receive the full assessment and the written report, and the fee still applies. A report that says you do not meet the criteria is a clinical finding, not a failed purchase, and it often identifies what is going on instead.
Any clinic that implies a diagnosis is guaranteed is telling you something about itself.
Questions to Ask Before You Pay
Before booking anywhere, ask what the fee includes, who conducts the appointment and what their registration is, how long it lasts, whether the report and GP letter are included, what titration costs per month, and what happens if you are not diagnosed.
If a clinic cannot answer those six questions in writing, that is useful information.
Frequently Asked Questions
Why do private ADHD assessment prices vary so much?
Because they cover different things. Some fees include the report and GP letter; others charge for both separately. Compare what is included, not just the headline figure.
Does the assessment fee include medication?
No. Medication is dispensed by a pharmacy and charged separately.
Will my GP take over prescribing?
Often, under a shared care agreement once your dose is stable — but they are not obliged to, and some practices decline.
Conclusion
A private ADHD assessment in the UK typically costs between £900 and £1,500, and ours is £650 for adults. The number that decides your first year, though, is not the assessment fee. It is what happens afterwards.
Ask about titration before you book, not after. If you would like to talk it through first, our team is happy to answer questions before you commit to anything.
