How Much Does a Private ADHD Assessment Cost in the UK?
A private adult ADHD assessment in the UK typically costs between £695 and £1,200, depending on the provider and whether your appointment is online or in person.
But the assessment fee is only part of the cost. If you are diagnosed and choose medication, you may also need to budget for titration, prescriptions, shared care and ongoing reviews.
In England, an NHS-funded assessment may also be available through Right to Choose, where a GP referral is required and eligibility criteria apply.
ADHD Assessment Costs at a Glance
The amount you pay for an ADHD assessment depends on the route you choose and whether treatment is needed after diagnosis. This national guide compares published prices from UK ADHD providers for adult diagnostic assessments, including online and in-person options. Harley Street Mental Health is included and clearly identified in the comparison.
It also covers potential additional costs, including titration, private prescriptions, shared care and annual reviews, alongside child ADHD assessment costs, NHS Right to Choose, and what to check before choosing a provider. Prices are a guide rather than an individual quote, so payment terms, deposits, instalments, cancellations and refunds should be confirmed directly with the provider before booking.

Providers may use a structured diagnostic interview alongside the clinical assessment.
Additional Testing
Some clinics include computerised assessments in their fee, while others charge separately.

The Costs That Come After Your Assessment
01.
Titration
Appointments while your medication and dose are adjusted.
02.
Prescription Fees
The fee charged by a private clinic for issuing prescriptions.
03.
Shared Care
A possible one-off fee for arranging prescribing with your GP.
04.
Annual Review
Ongoing medication reviews after your treatment has stabilised.
Titration: The Cost Many People Forget to Budget For
Titration happens after diagnosis if you and your clinician decide medication is appropriate. Your medication may be adjusted gradually while your response, blood pressure, pulse and weight are monitored.
Providers generally use one of two pricing models:
Pay Per Appointment
You pay separately for each titration appointment.
Fixed Package
Some providers charge one fee covering a defined titration period.
Paying per appointment can cost less if your medication settles quickly, but more if additional appointments are needed. The number of appointments should depend on your individual clinical needs.
Prescription Fee
This is the fee your private clinic charges for issuing the prescription.
Medication Cost
This is what the pharmacy charges for the medication itself.
Private pharmacy prices can vary by medicine, strength, quantity and pharmacy. Patients should check the exact price directly with pharmacies rather than relying on an estimated medication cost.
You May Not Have to Pay for the Assessment
01.
Treatment Stabilised
Your specialist works with you to find a suitable medication and stable dose.
02.
Shared Care Requested
The specialist can ask your GP whether they are willing to take over prescribing.
03.
GP Decision
If accepted, prescribing can move to the NHS. If declined, private prescribing may need to continue.
Annual Reviews and Ongoing Monitoring
Once your medication and dose are stable, ongoing review is still important. A review checks whether your medication continues to work, remains suitable and is still being prescribed at an appropriate dose.
Some providers publish annual review prices while others do not.
What Could Your First Year Actually Cost?
A. No Medication
You pay for the ADHD assessment, with no medication, titration or prescription costs afterwards.
B. Medication, Shared Care
You pay for the assessment and titration while your medication is stabilised. If your GP accepts shared care, they may then take over ongoing prescribing.
C. Medication, Private Prescribing
You pay for the assessment and titration, then continue paying private prescription fees if prescribing remains with the private clinic.

Check the current wait time where you live
Waits differ depending on where you live, because funding and local commissioning policy differ from one ICB to the next, so a single national number would mislead you. The figures below are our own current estimates for our own service. They are not NHS statistics and they are not a guarantee.

Compare more than the headline assessment fee. Check who carries out the assessment, what the assessment includes, appointment format, waiting time, report provision, titration costs, prescription fees, ongoing review costs and what happens if your GP does not accept shared care.
Not necessarily. Some providers charge separately for titration appointments, private prescriptions and medication, while others offer packages containing some of these services. Check exactly what the quoted assessment fee includes before booking.
It can be. Several providers publish lower prices for online assessments, although this is not universal. When comparing the two, look at what is included in the fee as well as the appointment format rather than assuming the cheapest headline price provides the same service.
A properly conducted private ADHD diagnosis does not automatically mean that your GP will agree to take over prescribing. Shared care is a separate arrangement and a GP can decide whether to accept it. If ongoing NHS prescribing is important to you, ask the private provider about their shared care process before starting treatment.
There can be two separate costs: the clinic’s fee for issuing a private prescription and the pharmacy’s charge for the medication itself. Pharmacy prices can vary depending on the medicine, dose and pharmacy, so medication costs should be checked separately from the clinic’s prescribing fee.
Coverage varies between insurers and policies. Some policies may exclude ADHD as a developmental or pre-existing condition, while others may provide limited cover subject to requirements such as pre-authorisation or a GP referral. Check directly with your insurer before booking.
If you choose medication, additional costs can include titration while your dose is adjusted, prescription fees, the medication itself, a shared care letter where applicable, and ongoing or annual reviews. These costs should be considered when comparing providers rather than looking only at the initial assessment price.
Providers do not necessarily include the same things in their assessment fee. Differences can include appointment length, informant questionnaires, structured diagnostic interviews, additional testing, whether the first prescription is included and how quickly you receive your written report.
Yes. In England, eligible patients may be able to access an NHS-funded ADHD assessment through Right to Choose. A GP referral is required and eligibility criteria apply, so you should check the current position in your area before requesting a referral.
Private ADHD assessment prices vary between providers and according to whether the assessment is online or in person. The providers compared for this guide showed online adult assessment prices starting from around £695, while in-person assessments can cost more. Remember that the assessment fee may not include later treatment costs.
What makes you different to other clinics?
We hand pick all of our clinicians to ensure that they have the same values as us.
This ensures that our service users are actually listened to and are the heart of our treatment plans.
We recognise that diagnosis and treatment plans cannot simply be “one size fits all” and our personalised down to earth approach aims to keep the process as easy as possible.
We will try to keep your costs low where possible. Once you are on the right dose and feeling settled (you may need one or two medication titration appointments to achieve this), you can order your medication through the repeat medication process.
Following two months of being on the same dose, with no further changes, we will consider returning your care to your GP.
Can I see you on the NHS?
We are a private clinic, and therefore you cannot be seen by us as part of the NHS. <br><br>We can write to your GP once you are stable on your treatment to ask them to take over prescribing as part of a Shared Care Agreement, however they are under no obligation to accept this agreement.
Do I need a referral?
Our clinicians can see you directly without a referral, however a condition of all appointments is that you agree for Harley Street Mental Health to copy your GP into all assessment and treatment plans.
We are happy to accept referrals from other clinicians, however this is not necessary to use our service.
What happens during an appointment?
If you have booked a virtual appointment, you will be sent an invitation through our clinic software known as “Semble”. On the day of your appointment, you click the link and will enter into a video interview with one of our clinicians.
If you have booked an in-person appointment you will be greeted by your clinician in the waiting room.
Do you accept insurance?
Currently we do not accept insurance, and all of our assessments and treatment plans are self funded, and therefore we encourage you to look at the “fees” page prior to booking.
Do you prescribe medication?
Our team are able to prescribe medication as part of your treatment plan if this is required. Our prescriptions are private, and therefore you will be liable for the cost of the prescription and the medication.
Hod do I know if the treatment will be beneficial?
Unfortunately, there are no guarantees with psychiatry. All of our clinicians are extremely experienced and prescribe based on the most up to date evidence base. You will be involved in your treatment plans at all stages.
I have a complaint?
We are sorry to hear that you have a complaint. Please see the complaints section of our website or email complaints@hsmh.co.uk where we will endeavour to resolve your complaint in a timely manner.
What are the fees associated with ADHD Assessments?
Please see the fees section on the website. It is important that you are aware of all costs prior to starting treatment. An ADHD assessment costs £715 and lasts approximately 1.5 hours and will include a detailed written report and treatment plan (includes a prescription which will posted to your chosen pharmacy, if medication is considered suitable for you).
The cost of medication will be in addition to this and paid directly to your chosen pharmacy.
We then require service users to attend titration appointments at £150 each where your medication is adjusted until most effective. Once you move on to repeat prescriptions, they will cost £48 for a monthly prescription.
Once you are stable on your medication (around two months of being on the same dose, with no further changes and you feel much better) you can ask us to write to your GP and enter into a shared care agreement which costs £125. Your GP is under no obligation to accept a shared care agreement, and therefore we encourage all service users to discuss this with their GP prior to using our service.
Are you registered with the CQC?
Yes, we have been approved for registration with the Care Quality Commission
