The bottom line: A reputable private ADHD assessment in the UK currently costs around £800, but the total path to medication stability often reaches £2,500. To avoid wasting money, you must confirm your GP will honour a Shared Care Agreement before booking, as many UK surgeries are now refusing to take over private prescriptions.
If you have tried to get an ADHD referral through your GP recently, you already know the system is broken. We are seeing waiting lists in some parts of the UK that stretch towards 2030. This is essentially the NHS’s way of saying that you are on your own.
This has left thousands of people in a desperate spot. I’ve been looking at the state of the private market for 2026 and it is a bit of a Wild West. Prices are shifting and some clinics are essentially diagnosis mills that your GP will never trust for a Shared Care Agreement.
The real price of going private
Do not be fooled by the headlines you see on social media ads. That is almost never the final bill. In the UK today you have to think about the total cost to stability. This includes the assessment, the titration where you find the right medication, and the administrative paperwork.
For a reputable clinic in 2026, you should expect to pay around £800 for the initial diagnostic interview. If you decide to go for medication, you will then be hit with titration fees which are usually around £150 per session. You also have the actual cost of the pills which can be another £100 a month. By the time you are stable enough to even ask for a Shared Care Agreement, you will likely have spent closer to £2,500.
Who can you actually trust
If you want your diagnosis to hold any weight with the NHS later, you need a consultant psychiatrist rather than a specialist nurse. While nurses are highly capable, many GPs in Scotland and Northern Ireland are now using a non-doctor diagnosis as a reason to reject Shared Care and save their local budget.
Berkeley Psychiatrists is currently one of the most straightforward options if you want a virtual service that does not feel like a factory. If you have a larger budget and want a report that is basically bulletproof, The ADHD Centre remains the gold standard. Their consultants are top tier and GPs generally respect their paperwork more than the newer or cheaper startups.
The Right to Choose postcode lottery
If you are in England, you have a legal right to ask your GP to refer you to a private clinic and have the NHS foot the bill. This is called Right to Choose. You can pick providers like Psychiatry UK or ADHD 360 and the funding follows the patient.
But if you are in Scotland, Wales, or Northern Ireland, this right does not exist. You are generally stuck between the local NHS waiting list or paying the full private fee yourself. In Wales, you can sometimes apply for an Individual Funding Request, but these are rarely granted for ADHD unless your case is extremely complex.
The Shared Care trap
This is the most important part that most people miss. Even with a perfect private diagnosis, your GP can legally say no to taking over your prescriptions.
In 2026, we are seeing a massive postcode lottery where surgeries in places like Essex, East London, and parts of Glasgow are flatly refusing new Shared Care Agreements for ADHD to cut costs. Before you spend a single pound of your own money, go and talk to your GP. Ask them point blank if they will honour a Shared Care Agreement from a registered private clinic. If they say no, you need to know that now before you are stuck paying for private prescriptions forever.
