NHS ADHD Waiting Times
The average wait for an NHS ADHD assessment is 2 to 5 years. For many people, that wait has a real impact on work, relationships, and mental health. This guide covers the current situation, the Right to Choose pathway, private assessment options, and what you can do while you wait.
Short answer: The average NHS wait for an ADHD assessment is 2 to 5 years, with some areas reporting waits of 7+ years. You have three options: (1) use the Right to Choose pathway to access a private provider through the NHS, (2) pay for a private ADHD assessment (typically £500–£900), or (3) take a free 2-minute ADHD screening while you wait to understand your symptoms better.
Think you might have ADHD? You are not alone. Millions of adults in the UK are navigating the same journey — from recognising symptoms to seeking assessment. This guide is here to help you understand your options and take your next step.
ADHD Assessment Wait Times in the UK
Demand for ADHD assessments has surged across the UK, far outpacing the capacity of NHS services. Here is what the waiting times look like in 2026.

The human cost of waiting
Long waiting times are not just an inconvenience. Research consistently shows that undiagnosed and untreated ADHD is associated with:
The Right to Choose Pathway
The Right to Choose is one of the most effective ways to reduce your waiting time from years to weeks — and it is funded by the NHS.
What is it?
Under Section 75 of the NHS Act 2006, NHS England patients have the legal right to choose any qualified provider for their first outpatient appointment. This includes NHS-approved private ADHD assessment services. The NHS pays for the assessment — you do not.
Who is eligible?
The Right to Choose applies to patients registered with a GP in England. It does not currently apply in Wales, Scotland, or Northern Ireland, which have separate NHS systems. You must be referred by your GP — self-referral is not covered under this pathway.
How to use the Right to Choose
Speak to your GP
Tell your GP you would like to be referred for an ADHD assessment and that you want to use your Right to Choose. You do not need to justify this — it is your legal right.
Choose an approved provider
Select an NHS-approved provider that offers ADHD assessments. Providers like Psychiatry-UK, Clinical Partners, and others are approved under this pathway. Your GP can help you find options.
GP sends the referral
Your GP sends a referral to your chosen provider. The provider contacts you to arrange the assessment, which is typically conducted via video call.
Assessment and next steps
The provider conducts a comprehensive ADHD assessment. If diagnosed, they write to your GP with treatment recommendations and can initiate a shared care agreement for ongoing prescribing.
Note: Some GPs are unfamiliar with the Right to Choose for ADHD. If your GP declines, you can contact your local Integrated Care Board (ICB) or the NHS England complaints process.
Private ADHD Assessment Options
If the Right to Choose is not available to you, or you prefer a fully private route, here is what to expect from a private ADHD assessment in the UK.
What to expect
- A detailed clinical interview (60-90 minutes) covering symptoms, history, and daily functioning
- Review of childhood symptoms — you may be asked to provide school reports or a collateral history from a family member
- Assessment against DSM-5 or ICD-11 diagnostic criteria
- A written report with diagnosis, recommendations, and a treatment plan
- Most assessments are available online via video call
Typical costs
Costs vary significantly by provider and location. Some providers offer payment plans. Once stabilised on medication, your GP may agree to shared care prescribing on the NHS.
Advantages
- Assessment within weeks, not years
- Choose your own clinician and approach
- Online assessments widely available
- Detailed written report for your records
Things to consider
- Significant upfront cost (£500-£1,500+)
- Your GP may not agree to shared care prescribing
- Quality varies — check clinician credentials
- Some providers have long waits too (check before booking)
Getting Your GP On Board
Whether you are diagnosed through the Right to Choose or a private assessment, ongoing medication usually requires a shared care agreement with your GP.
What is shared care?
A shared care agreement is an arrangement where a specialist (the diagnosing clinician) and your GP share responsibility for your ongoing treatment. The specialist provides the diagnosis, treatment plan, and initial medication titration. Your GP then takes over routine prescribing and monitoring, with the specialist available for advice.
NICE guideline NG87 recommends that GPs should consider entering shared care arrangements for ADHD medication. However, GPs are not obligated to agree — shared care is a voluntary arrangement. If your GP is reluctant, the diagnosing clinician can often help by providing clear guidance and support.
While You Wait: Understand Your Symptoms
The wait for an ADHD assessment can feel endless. While no screening tool replaces a professional diagnosis, understanding your symptoms — including common co-occurring conditions like anxiety and depression — can help you prepare for your assessment and have more informed conversations with your GP.

How long is the NHS waiting list for ADHD assessment?
NHS ADHD waiting times vary significantly by region but average 2 to 5 years across England. Some areas report waits of over 7 years. Wales, Scotland, and Northern Ireland have their own services with similarly long waiting lists. These figures reflect the growing demand for adult ADHD assessments, which has increased dramatically since 2020.
What is the Right to Choose for ADHD?
The Right to Choose is an NHS England policy (under Section 75 of the NHS Act 2006) that allows patients to choose any qualified provider for their first outpatient appointment, including private ADHD assessment services approved by the NHS. Your GP refers you to an NHS-approved private provider, and the NHS funds the assessment. This can reduce waiting times from years to weeks.
Can I get a private ADHD assessment in the UK?
Yes. You can pay for a private ADHD assessment without a GP referral, though having one is recommended. Private assessments typically cost between £500 and £1,500 and can be arranged within weeks rather than years. Make sure your assessor is a qualified psychiatrist or clinical psychologist registered with the appropriate professional body (GMC, HCPC, or equivalent).
How much does a private ADHD assessment cost in the UK?
Private ADHD assessments in the UK typically cost between £500 and £1,500. The price varies depending on the provider, location, and whether the assessment is conducted in person or online. Some providers offer payment plans. Through the Right to Choose pathway, the NHS covers the cost of assessment with an approved provider, so you may not need to pay privately.
Will my GP accept a private ADHD diagnosis?
Most GPs will accept a private ADHD diagnosis if it was conducted by a qualified professional following NICE guidelines (NG87). However, prescribing medication based on a private diagnosis requires a shared care agreement between your GP and the diagnosing clinician. Some GPs may be reluctant to enter shared care, though NICE guidance supports this approach. If your GP declines, you can request a second opinion or contact your local ICB (Integrated Care Board).
Can I get ADHD medication while waiting for an NHS assessment?
Generally, no — you cannot get ADHD medication through the NHS without a formal diagnosis. However, there are options: you can use the Right to Choose pathway for a faster NHS-funded assessment, get a private assessment and ask your GP to enter a shared care agreement for prescribing, or access medication through a private prescriber (at your own cost) while waiting. Your GP may also be able to support you with non-medication strategies in the meantime.
