ADHD Waiting Times NHS UK 2026: The Best Complete Guide

ADHD Waiting Times NHS UK 2026: The Complete Guide

If you have been told to wait years for an ADHD assessment on the NHS in the UK, you are not alone. ADHD waiting times on the NHS UK have reached record levels in 2026, with some areas reporting waits of up to eight years. This guide explains exactly how long the wait is, why it has grown so long, and — most importantly — what practical steps you can take right now.

ADHD Waiting Times NHS UK: How Long Is the Wait in 2026?

The picture varies significantly depending on where you live. As of December 2025, there were 562,450 open referrals for a possible ADHD diagnosis in England alone.

Across the UK, the average waiting time for an adult ADHD assessment via the standard NHS pathway is now over two years. Around 62% of adults on waiting lists have already been waiting for more than a year.

In some parts of the UK, the situation is much worse:

• Kent, Sussex, and parts of London: 5–7 years
• Some NHS trusts: up to 8 years or more
• Children (via CAMHS): typically 18 months to 4 years

Only around 10% of adults and 9% of children are seen within the NHS’s own recommended 13-week timeframe.

Why Are ADHD Waiting Times on the NHS UK So Long?

The surge in ADHD waiting times has several causes working together.

First, awareness has grown significantly. More parents, adults, and healthcare professionals now recognise the signs of ADHD. Parent-reported prevalence of ADHD and autism rose by around 25% between 2022 and 2024, driving a sharp rise in referrals.

Second, NHS services have not expanded at the same pace as demand. There is a national shortage of consultant psychiatrists and specialist nurses qualified to diagnose and treat ADHD. NHS Integrated Care Boards (ICBs) have spent over £512 million on private ADHD and autism assessments since 2023/24 — a clear sign of how strained the system has become.

Third, some ICBs have restricted or paused Right to Choose referrals in their area, placing even more pressure on already stretched local services.

What Is NHS Right to Choose for ADHD?

Right to Choose is one of the most important options available to you if you live in England and are waiting for an ADHD assessment.

Under Section 75 of the NHS Act 2006, you have the legal right to choose any NHS-approved provider for your first outpatient appointment — including private ADHD clinics that hold NHS contracts. This means you can access a faster ADHD assessment without paying a penny.

This is not a workaround or a loophole. It is a legal right.

Important: Right to Choose applies to England only. If you live in Wales, Scotland, or Northern Ireland, different NHS pathways apply.

How to Use Right to Choose for ADHD (Step-by-Step)

Using Right to Choose is more straightforward than many people expect. Here is exactly how it works.

Step 1 — Book a GP appointment Speak with your GP about your ADHD symptoms. Describe clearly how they affect your daily life, work, relationships, and wellbeing. Your GP may ask you to complete an ASRS screening questionnaire before making a referral.

Step 2 — Request Right to Choose Ask your GP directly: “I would like to use my Right to Choose for my ADHD referral.” Your GP should not refuse this request under NHS England guidelines. If they are unsure, direct them to the NHS England ADHD Taskforce guidance.

Step 3 — Choose your provider Ask your GP to refer you to an NHS-approved provider. Well-known Right to Choose providers include Psychiatry UK, ADHD 360, and Clinical Partners. Current wait times through Right to Choose range from 6 weeks (smaller regional providers) to 18 months (highest-demand national providers).

Step 4 — Wait for contact Your chosen provider will contact you to confirm your referral and book your assessment appointment.

Step 5 — Attend your assessment Your assessment is fully funded by the NHS. You will not be charged. If ADHD is confirmed, your treatment and medication will be managed through the NHS going forward.

What If My GP Refuses Right to Choose?

Some GPs are unfamiliar with Right to Choose or may initially push back. If this happens, you have options:

• Ask to speak with the practice manager
• Put your request in writing
• Seek a second opinion from another GP at the same practice
• Contact ADHD UK — they provide template letters specifically for this situation

You have a legal right to this referral if you live in England.

Private ADHD Assessment UK: What Does It Cost?

If you are not eligible for Right to Choose, or if you prefer a faster route with no waiting, a fully private ADHD assessment is available across the UK.

Typical costs in 2026:

• Adult assessment: £500 – £1,500
• Child assessment: £600 – £2,000

Costs vary depending on provider, location, and whether a full written report is included. Some private providers offer shared care arrangements, where your NHS GP manages ongoing medication after a private diagnosis — reducing long-term costs.

What to Do While You Wait for Your ADHD Assessment

Being on a waiting list can be exhausting. Here are practical steps to take in the meantime.

Keep a symptom diary. Record how ADHD symptoms affect your day-to-day life, work, and relationships. This will be valuable during your assessment and strengthens your case.

Talk to your GP about interim support. Mental health referrals, occupational therapy, or talking therapies may be available while you wait. Ask specifically what support is available.

Tell your employer or school. You do not need a formal diagnosis to request reasonable adjustments. Describe the impact of your difficulties clearly and practically.

Contact ADHD UK. This charity offers support, resources, and a peer community for people at every stage of the ADHD journey.

ADHD Waiting Times for Children: Advice for Parents

If you are a parent concerned about your child’s ADHD, the pathway is slightly different.

Start by speaking to your child’s GP or school SENCO (Special Educational Needs Coordinator). Ask for a referral to CAMHS (Child and Adolescent Mental Health Services) or a paediatric neurodevelopmental service.

If you live in England, Right to Choose may also apply to children’s referrals — ask your GP whether it is available in your area.

You do not need a formal diagnosis for your child’s school to provide support. Under the SEND Code of Practice, schools have a legal duty to support children with identified needs. Read our SEN educational support guide for more information.
