Getting an ADHD assessment on the NHS in the UK can take a long time, especially for adults. It is no surprise that more people are looking at private ADHD assessments for themselves or their children.
But private ADHD care can be confusing. There are many providers, different prices, different levels of assessment quality, and a lot of uncertainty about whether your NHS GP will accept the diagnosis or help with prescriptions afterwards.
This guide explains what a proper ADHD assessment should include, how private ADHD assessments work in the UK, typical costs, how NHS-funded Right to Choose works in England, whether NHS “rebates” exist, and what to check before booking.
Why are so many people going private for ADHD?
Awareness of ADHD in adults and children has grown quickly. More people now recognise that ADHD is not just about being hyperactive at school. It can affect concentration, organisation, emotional regulation, impulsivity, sleep, money, relationships, study and work.
At the same time, many NHS ADHD services are under heavy pressure. Waiting times vary by area, but in some places people wait months or years for assessment. For someone struggling at work, university or school, that delay can have a serious effect on daily life.
Common reasons people explore private ADHD assessment include:
- long NHS waiting lists
- work, study or relationship problems becoming harder to manage
- difficulty accessing local adult ADHD services
- wanting a clearer explanation for lifelong symptoms
- needing documentation for workplace, university or school adjustments
- wanting to understand medication options sooner
- exploring Right to Choose in England
Before spending money, it is important to understand what a good assessment should look like and what private diagnosis does, and does not, guarantee.

What should a proper ADHD assessment include?
In the UK, ADHD diagnosis and treatment should be guided by NICE guideline NG87 on ADHD diagnosis and management. You can read the guideline on the NICE website.
In plain English, a good ADHD assessment should be more than a quick questionnaire. It should usually include:
- A suitably qualified professional — such as a psychiatrist, specialist ADHD clinician, paediatrician, specialist nurse prescriber, clinical psychologist or another professional with appropriate ADHD expertise.
- A detailed history — including current symptoms, childhood symptoms, education, work, relationships, daily functioning and coping strategies.
- Evidence across settings — ADHD symptoms should be considered across home, school, work, social life or family life, not just in one narrow context.
- Childhood history — for adults, this may involve school reports, parental input, old records or discussion of early patterns where possible.
- Impact on daily life — the assessment should consider whether symptoms cause significant impairment, not simply whether traits are present.
- Screening for other conditions — including anxiety, depression, autism, trauma, bipolar disorder, sleep problems, substance use, learning difficulties or physical health issues.
- Rating scales used properly — questionnaires can support the assessment, but should not be the only evidence used.
- A written report — explaining the diagnosis, reasoning, evidence considered and treatment recommendations.
A thorough report may include recommendations about medication, therapy, ADHD coaching, workplace adjustments, university support, school support, sleep, routines and follow-up.
Be cautious if a provider offers a very cheap, very fast or questionnaire-only assessment with little discussion of childhood, impairment, other conditions or treatment planning.
Types of private ADHD assessment in the UK
People often say they are “going private”, but there are several different routes. The details matter because cost, NHS acceptance and prescribing arrangements can differ.
1. Fully private self-pay ADHD assessment
This is the simplest private route. You contact a private clinic or clinician directly, book an assessment and pay the full cost yourself.
Possible advantages:
- usually faster than many local NHS services
- more choice of provider
- online or in-person options
- more appointment flexibility
- potentially faster medication titration if appropriate
Possible disadvantages:
- you pay for the assessment
- you may also pay for titration, follow-ups and prescriptions
- your NHS GP may not agree to shared care afterwards
- quality varies between providers
- you may still need NHS reassessment in some circumstances
Fully private providers may include independent psychiatrists, ADHD clinics, private mental health groups, neurodevelopmental clinics and online assessment providers.
2. Private assessment through health insurance
Some private health insurance policies cover ADHD assessment or mental health assessment, especially through employer schemes. However, policies vary widely.
Before booking, check:
- whether adult or child ADHD assessment is covered
- whether you need GP referral or insurer authorisation first
- whether follow-up appointments are covered
- whether medication titration is covered
- whether there are annual mental health limits
- whether pre-existing symptoms are excluded
Even if insurance pays for the assessment, you may still face the same shared-care issue afterwards: will your NHS GP take over prescribing once you are stable?
3. NHS-funded Right to Choose ADHD assessment in England
If you live in England and are registered with a GP in England, you may be able to use the NHS Right to Choose route. This allows eligible patients to choose certain NHS-contracted providers for assessment, including some independent ADHD providers.
Right to Choose is not the same as paying privately. In this route:
- your GP refers you to an eligible provider
- the assessment is NHS-funded from the start
- you do not pay the assessment fee yourself
- the provider should work to NHS standards and contract requirements
- waits may be shorter than local NHS ADHD clinics, depending on provider demand
You can read general NHS information about patient choice here: your choices in the NHS.
Right to Choose is only available in England and does not work in the same way in Scotland, Wales or Northern Ireland. It is also not a refund route. You normally need to use it before assessment, not after paying privately.

How much does a private ADHD assessment cost?
Prices change frequently and vary by provider, age group, complexity and whether medication titration is included. As a rough guide for adults in the UK:
- Initial ADHD assessment: often around £500–£1,200.
- Assessment plus titration package: often around £800–£1,800+.
- Follow-up appointments: often around £120–£250 each.
- Private prescriptions: may involve prescription fees plus the medication cost itself.
- Annual reviews or letters: may be charged separately.
Children’s assessments can be similar or higher, because they may require more input from parents, school, developmental history and sometimes multidisciplinary review.
Hidden or ongoing costs can include:
- medication titration appointments
- private prescription fees
- the cost of medication if not prescribed on the NHS
- follow-up reviews
- letters for university, school or work
- repeat assessment if the first report is not accepted elsewhere
- time off work, childcare or travel
Do not judge a provider only by the headline assessment price. Ask what the total first-year cost could be if diagnosis, titration, prescriptions and follow-ups are needed.
Will the NHS accept a private ADHD diagnosis?
This is one of the most important questions, and the honest answer is: not automatically.
In theory
If your private assessment follows NICE guidance, is completed by a suitably qualified professional, includes a detailed report and provides a clear treatment plan, your GP or local NHS service may consider it valid and may consider shared care.
Shared care usually means the specialist diagnoses and stabilises medication, then the GP prescribes under an agreed plan while the specialist remains responsible for periodic review and specialist advice.
In practice
Acceptance varies. Some GPs and local NHS systems are cautious about private ADHD diagnoses, especially if they have concerns about assessment quality, documentation, medication monitoring or patient safety.
Your NHS GP is not usually obliged to prescribe ADHD medication just because a private provider has recommended it. Shared care depends on factors such as:
- local NHS policy
- your GP practice’s prescribing policy
- the quality of the private assessment report
- whether the provider follows NICE guidance
- whether medication titration has been completed safely
- whether the private specialist remains available for review
- whether the GP feels prescribing is safe and appropriate
Before booking privately, ask your GP practice:
“If I have a private ADHD assessment with a qualified provider that follows NICE guidance, and if medication is titrated to a stable dose, would the practice consider a shared-care agreement?”
You may not get a guaranteed answer, but it can help you understand the likely local position before spending money.
Are there NHS rebates for private ADHD assessments?
For most people, no. There is no standard UK scheme where you pay privately for an ADHD assessment and then claim the money back from the NHS later.
What can happen instead:
- NHS-funded assessment from the start — through Right to Choose in England, if you are eligible and your GP refers you through that route.
- NHS prescribing later — your GP may agree to shared care after private diagnosis and titration, but this does not refund the assessment cost.
- Insurance reimbursement — if you have private medical insurance and the assessment is covered, your insurer may pay or reimburse according to the policy.
There may be rare local or exceptional funding situations, but these are not something most people can rely on. If you self-pay, assume you will not get the assessment fee back from the NHS.
Examples of different ADHD assessment routes
Example 1: adult in England using Right to Choose
Alex is 34 and has struggled for years with deadlines, disorganisation, impulsive spending and emotional overwhelm. His local NHS ADHD waiting list is very long, and he cannot afford ongoing private fees.
He asks his GP about Right to Choose. The GP agrees to refer him to an NHS-contracted ADHD provider. Alex is assessed through that route without paying a private assessment fee directly. If diagnosed and treated, prescribing and follow-up arrangements depend on the provider, GP and local shared-care process.
Example 2: child outside England
Samira is 10 and her school raises concerns about attention, impulsivity and restlessness. Her parents speak to the school SENCO and then their GP, who refers to the local paediatric or neurodevelopmental service.
Because Right to Choose is an England-only route, the family cannot use it in the same way if they live in Scotland, Wales or Northern Ireland. They consider private assessment but are warned that the local NHS team may still want to review or reassess before taking over medication.
Example 3: fully private assessment with mixed NHS response
Martin pays privately for an adult ADHD assessment and medication titration. The assessment helps him understand years of difficulty, but his GP practice later explains that it does not enter shared-care agreements with that private-only provider.
Martin then has to choose between continuing private prescriptions and reviews, joining the NHS waiting list, or asking whether another NHS-approved pathway is available. This is why checking shared-care expectations before booking is so important.
How to choose a private ADHD provider safely
Quality varies, so it is worth checking the provider carefully before paying.
Ask these questions:
- Do they follow NICE NG87? They should clearly explain how their assessment meets UK ADHD guidance.
- Who completes the assessment? Check whether the clinician is a psychiatrist, paediatrician, clinical psychologist, specialist nurse or another appropriately qualified professional.
- Are they properly registered? Depending on role, this may include GMC, NMC, HCPC or another relevant professional register.
- How long is the assessment? A meaningful ADHD assessment is usually detailed and should not feel like a 20-minute form-filling exercise.
- Do they ask about childhood? Adult ADHD assessment should consider symptoms since childhood where possible.
- Do they collect information from other sources? This might include school reports, parent input, partner input, questionnaires or previous medical records.
- Do they screen for other conditions? Anxiety, depression, autism, trauma, sleep problems and bipolar disorder can overlap with ADHD symptoms.
- What do you receive in writing? Ask whether you get a full diagnostic report, reasoning, recommendations and medication plan if relevant.
- How do they handle medication titration? Ask who monitors dose changes, side effects, blood pressure, pulse and follow-up.
- Do they support shared-care requests? Ask whether they provide shared-care letters and remain available for specialist review.
- What are the ongoing costs? Include prescriptions, follow-ups, annual reviews and letters.
Warning signs include:
- very cheap, very fast assessments with little clinical detail
- questionnaire-only diagnosis
- unclear clinician qualifications
- no discussion of childhood history
- no screening for other mental health or neurodevelopmental conditions
- no clear medication monitoring plan
- pressure to pay quickly
- unclear policy on reports, follow-up or shared care

Step-by-step: how to get a private ADHD assessment
1. Speak to your GP first
Explain your symptoms, how long they have been present, and how they affect work, study, relationships, home life or parenting. Ask about local NHS waiting times and whether Right to Choose is available if you live in England.
Also ask about shared care before paying privately.
2. Decide which route you are using
Your options may include:
- local NHS ADHD referral
- Right to Choose referral in England
- fully private self-pay assessment
- private assessment through insurance
3. Research providers carefully
Check qualifications, registration, process, assessment length, reviews, medication arrangements, report quality and shared-care support.
4. Get costs in writing
Ask for a breakdown of:
- assessment fee
- titration fee
- follow-up fees
- private prescription fees
- medication costs
- letters or reports
- annual review costs
5. Prepare for the assessment
Useful information may include:
- school reports
- university or workplace evidence
- previous mental health letters
- examples of current difficulties
- information from a parent, partner or close friend
- current medication list
- history of anxiety, depression, autism, trauma, sleep problems or substance use
6. Ask what happens after diagnosis
Diagnosis is only one part of the process. Ask what happens if ADHD is confirmed, whether medication is appropriate, who handles titration, when follow-up happens, and whether the provider will write to your GP.
7. Share the report with your GP
If you want NHS involvement later, make sure your GP receives the full report. Ask whether shared care can be considered once medication is stable, but be prepared for the possibility that the GP may decline.
Medication, titration and shared care explained
If medication is recommended, you will usually go through a process called titration. This means starting medication, adjusting the dose gradually and monitoring benefits and side effects.
Monitoring may include:
- blood pressure
- pulse
- weight or appetite
- sleep
- mood
- side effects
- symptom improvement
Once a stable dose is reached, the private provider may ask your GP to take over prescribing under shared care. The GP can agree, decline or ask for more information depending on local policy and clinical judgement.
This is why ongoing costs matter. If shared care is not accepted, you may need to keep paying privately for prescriptions, reviews and medication.
Looking after your mental health while waiting
Whether you choose NHS, Right to Choose or private care, there may still be waits for assessment, diagnosis, titration or follow-up. During that time, it is worth putting support in place.
This may include:
- talking therapies or counselling for anxiety, low mood or stress
- ADHD-friendly routines and reminders
- workplace or university adjustments
- sleep and exercise routines
- peer support groups
- support with debt, admin or organisation if these are major problems
- support for parents and schools if a child is waiting for assessment

FAQ: private ADHD assessments in the UK
How much does a private ADHD assessment cost?
Adult assessments often cost around £500–£1,200, but total costs can be higher once titration, follow-ups, private prescriptions and medication are included.
Can I get an NHS rebate after paying privately?
Usually no. There is no standard NHS rebate scheme where you pay privately and claim the assessment fee back later. Right to Choose in England is different because it is NHS-funded from the start.
What is Right to Choose for ADHD?
Right to Choose is an NHS route in England that may allow eligible patients to choose an NHS-contracted independent provider for ADHD assessment. Your GP usually needs to refer you through that pathway.
Does Right to Choose apply in Scotland, Wales or Northern Ireland?
No, not in the same way. Right to Choose is an England-specific NHS choice route. Other UK nations have different referral and funding systems.
Will my GP accept a private ADHD diagnosis?
Not automatically. Some GPs may consider shared care if the assessment is thorough and the provider follows NICE guidance, but others may decline due to local policy, safety concerns or provider quality concerns.
Can a private ADHD provider prescribe medication?
Some can, if they have appropriately qualified prescribers. Medication should involve careful titration and monitoring. Always ask who prescribes, how follow-up works and what it costs.
What is shared care?
Shared care is when a specialist starts and stabilises medication, then the GP prescribes under an agreed plan while the specialist remains involved for reviews and advice. GPs are not always required to accept shared care.
Is an online ADHD assessment valid?
It can be, if it is carried out by a suitably qualified clinician, follows NICE guidance, gathers enough evidence and provides a detailed report. A quick questionnaire-only online assessment is a warning sign.
Can I use a private ADHD diagnosis for work or university adjustments?
Often yes, but requirements vary. Workplaces, universities and schools may ask for a clear report with functional impact and recommendations. Check what evidence they require before booking.
What happens if I am assessed and it is not ADHD?
A good assessment should still be useful. It may identify anxiety, depression, autism, trauma, sleep problems, learning difficulties or another explanation, and recommend next steps.
Should I choose the cheapest ADHD provider?
Not based on price alone. A very cheap assessment can become expensive later if the report is poor, medication follow-up is unclear, or the NHS will not consider shared care.
Can children get private ADHD assessments?
Yes, but child assessments should involve developmental history, parent input and school information where possible. Medication and NHS acceptance can be more complex, so check arrangements carefully.
Final takeaway
Private ADHD assessment can be faster than many NHS routes, but it is not risk-free. Costs can build up, quality varies, and NHS acceptance for prescribing is not guaranteed.
The safest approach is to speak to your GP first, ask about NHS and Right to Choose options, check shared-care expectations, choose a provider that follows NICE guidance, and budget for the full pathway rather than the assessment alone.
If you are paying privately, assume you will not receive an NHS rebate. Any later NHS prescribing or shared-care support should be treated as possible, not guaranteed.
