How Long Is the NHS ADHD Waiting List? (By Region)

The question everyone asks when they start looking into ADHD assessment: how long will I actually have to wait? The honest answer is that it depends entirely on where you live, and the variation across the UK is enormous. Some areas manage assessments within a year. Others have waiting lists stretching beyond a decade.

The Current Scale of the Problem

As of December 2025, NHS England data shows up to 735,157 open referrals that may be for ADHD assessment in England alone. That figure includes 562,480 referrals recorded in the Mental Health Services Dataset and a further 172,677 in the Community Health Services dataset.

In a national survey carried out for the independent ADHD Taskforce, 40% of respondents reported waiting two years or more. Some areas reported waits of 10 to 15 years. To put that in perspective: if you joined certain waiting lists today, you might not be assessed until well into the 2030s.

Why the Variation Is So Extreme

Adult ADHD services in the UK have historically been underfunded and unevenly distributed. Some regions have well-established specialist teams. Others rely on general psychiatry services that handle ADHD alongside everything else. The ADHD Taskforce's plain English summary confirmed that where you live plays a major role in the care you receive.

Demand has also grown significantly. Increased public awareness means more people are seeking assessment, which is a positive development in terms of identification, but the service capacity hasn't kept pace. Referral rates have been climbing year on year, and the gap between demand and capacity continues to widen in most areas.

What the NHS Is Doing About It

The independent ADHD Taskforce, launched by NHS England in partnership with government, published its final report in November 2025. It made recommendations across diagnosis, treatment, and service design. NHS England has committed to publishing ADHD referral and waiting time data for the first time, which should improve transparency, though it will take time for structural changes to reduce actual waiting times.

From 2026/27, new payment guidance has been introduced for ADHD and autism services, which may improve how ICBs commission and fund assessment capacity. But these are system-level changes. If you're looking at a multi-year wait right now, they won't help you directly.

Your Options for Getting Assessed Sooner

1. 1

   Use Right to Choose. If you're in England, you have the legal right to be referred to an alternative NHS-funded provider. Waiting times through Right to Choose are typically shorter, though they have been increasing. Read our complete Right to Choose guide for step-by-step instructions.

2. 2

   Consider private assessment. A private ADHD assessment typically costs £500 to £950 and can often be booked within weeks. This is the fastest route but comes with important caveats around shared care and ongoing prescribing. See our article on private assessment costs.

3. 3

   Stay on the NHS list while exploring other options. There's nothing stopping you from remaining on the NHS waiting list while also pursuing Right to Choose or private assessment. If your private or RtC assessment happens first, you can cancel the NHS referral.

4. 4

   Check whether your employer will fund assessment. Some employers cover the cost of private assessment through occupational health budgets or employee assistance programmes. If you're self-employed, the cost may be tax-deductible as a business expense.

5. 5

   Track your wait. Our free Access to Work application tracker (available with a free account) also lets you monitor your assessment referral progress, so you're not left guessing.

What to Do While You Wait

A long waiting list doesn't mean you're stuck without support. You can start implementing ADHD management strategies now (many people find them helpful even pre-diagnosis). You can explore whether you're eligible for Access to Work support. And you can connect with peer support groups where others are navigating the same process.

If the wait is affecting your mental health, speak to your GP about interim support. The fact that you're waiting for ADHD assessment doesn't prevent you from accessing other mental health services in the meantime.
