Private vs NHS ADHD Assessment in the UK: Costs, Waits and What to Choose

The standard NHS route costs nothing. Your GP refers you to the local NHS adult ADHD service, you join the waiting list, and eventually you are assessed by an NHS psychiatrist. If diagnosed, your medication and ongoing care are managed within the NHS system with standard prescription charges (or free in Scotland and Wales).

The major drawback is waiting times. As our guide to NHS ADHD waiting times details, waits of two to five years are common across England, with some areas exceeding seven years. During this wait, you have no access to medication or formal ADHD support through the NHS. For many people, particularly those whose ADHD is significantly affecting their work, relationships or mental health, this wait is simply too long to be practical.

The NHS pathway does have one clear advantage beyond cost: continuity of care. Once you are in the system, medication reviews, titration and repeat prescriptions are all handled within the NHS without additional steps or negotiations.

The Right to Choose pathway is available to NHS patients in England. Under Section 75 of the NHS Act 2006, you can ask your GP to refer you to a qualified provider of your choice rather than the local NHS service. The assessment is still NHS-funded - you pay nothing - but the waiting time is typically much shorter, often weeks to months rather than years.

Providers such as Psychiatry-UK, Clinical Partners and others accept Right to Choose referrals. You can compare options in our provider comparison guide. After diagnosis, the Right to Choose provider handles initial titration and then transfers your care back to your GP under a shared care agreement.

Right to Choose is not available in Scotland, Wales or Northern Ireland, where separate NHS systems operate. Even in England, some GPs are unfamiliar with the pathway and may initially resist processing the referral, though they are legally required to do so when the request is clinically appropriate.

A fully private ADHD assessment bypasses the NHS entirely. You contact a private clinic directly, book an appointment, and pay for the assessment yourself. Costs typically range from around 500 to 2,000 pounds depending on the provider, with most falling between 600 and 900 pounds for a standard adult assessment. Some providers offer payment plans.

The advantage is speed - you can often be seen within days or weeks. The assessment itself is clinically equivalent to an NHS assessment, conducted by a qualified psychiatrist using the same diagnostic criteria. Many private providers also offer follow-up titration packages, though these come at additional cost.

Our ADHD assessment cost guide breaks down what different providers charge and what is included in the fee. It is worth checking exactly what the quoted price covers, as some providers charge separately for the assessment report, follow-up appointments and prescription management.

The biggest issue with fully private assessment is what happens afterwards. Once you have a private diagnosis and need ongoing medication, you will want your GP to take over prescribing under a shared care agreement. Without shared care, you would need to continue seeing a private psychiatrist for every prescription, which can cost 200 to 400 pounds per appointment.

In theory, shared care should be straightforward. The private psychiatrist writes to your GP with the diagnosis and medication plan, and the GP agrees to prescribe and monitor under the specialist's guidance. In practice, some GPs and some Clinical Commissioning Groups (now Integrated Care Boards) refuse to enter into shared care agreements for privately diagnosed ADHD, arguing that the diagnosis was not made within their NHS pathway.

This is not universal - many GPs are happy to accept shared care - but it is common enough that you should consider it before choosing the fully private route. If your GP has already indicated they would be reluctant to engage in shared care, the Right to Choose pathway may be a more practical option, since the diagnosis comes from an NHS-funded provider and GPs are generally more willing to continue the care.

If you are in England and your GP will process the referral, Right to Choose is usually the best starting point. It is free, significantly faster than the standard NHS pathway, and results in a diagnosis that GPs are comfortable accepting for shared care. The main limitation is that availability depends on which providers have capacity at the time of your referral.

If Right to Choose is not available to you - because you are in Scotland, Wales or Northern Ireland, or because no Right to Choose provider currently has capacity - the decision is between waiting on the NHS list and paying privately. The key questions to ask yourself are: how significantly is the lack of diagnosis and treatment affecting your daily life right now, can you afford the private assessment fee, and is your GP likely to accept a private diagnosis for shared care purposes?

Some people choose a combined approach - joining the NHS waiting list while also pursuing private or Right to Choose assessment. This is perfectly reasonable and ensures you have a backup if one pathway stalls. There is no rule against being on multiple waiting lists simultaneously.

Whichever pathway you choose, the clinical assessment itself is the same. The diagnostic criteria do not change based on how you access the assessment. A diagnosis from any qualified psychiatrist is equally valid, regardless of whether the appointment was NHS, Right to Choose or private.
