As FCA-authorised private medical insurance experts who have arranged over 900,000 policies, we at WeCovr see the growing frustration first-hand. If you're an adult in the UK suspecting you have Attention Deficit Hyperactivity Disorder (ADHD), you're likely facing a daunting choice: join a multi-year NHS waiting list or find thousands of pounds for a private assessment. This guide provides the clarity you need to navigate your options in 2026.
The surge in awareness around adult ADHD has collided with a chronically under-resourced NHS, creating a perfect storm. Waiting lists for an initial psychiatric assessment in many parts of the UK now stretch from two to as long as seven years. For individuals struggling with focus, emotional regulation, and executive function, this delay isn't just an inconvenience—it can be life-altering.
This article breaks down the three main pathways to an adult ADHD diagnosis in the UK: the standard NHS route, the "Right to Choose" shortcut, and the fast but costly private option. We will also give a definitive answer on whether private medical insurance can help foot the bill.
The demand for adult ADHD assessments on the NHS has skyrocketed. Increased public conversation, better understanding among GPs, and the impact of the pandemic on mental health have all contributed to an unprecedented number of referrals.
Unfortunately, NHS funding and specialist staffing have not kept pace. As of early 2026, the situation is critical.
Here's a snapshot of what you might expect across the country:
| Region/Country | Estimated Standard NHS Wait Time (2026) | Notes |
|---|---|---|
| England | 2 - 7 years | Highly variable by NHS Trust. Right to Choose offers an alternative. |
| Scotland | 1 - 4 years | No "Right to Choose". Waiting times are also growing significantly. |
| Wales | 2 - 5 years | Pockets of extremely long waits. Services are stretched thin. |
| Northern Ireland | 2 - 4 years | Significant backlogs, particularly within the Belfast Health and Social Care Trust. |
If you live in England and the thought of a multi-year wait is unbearable, Right to Choose (RTC) is the single most important pathway you need to understand. It is a legal right enshrined in the NHS Constitution.
What is Right to Choose? Right to Choose allows you, as an NHS patient in England, to be referred for your assessment to a qualified private provider that has a contract with the NHS. The crucial part? The NHS funds the entire process, so it costs you nothing.
This route effectively lets you bypass your local NHS trust's long waiting list and access a provider with a much shorter one.
Pros and Cons of Right to Choose
| Pros | Cons |
|---|---|
| No Cost: The NHS covers the full cost of assessment and titration. | England Only: Not available in Scotland, Wales, or Northern Ireland. |
| Faster than NHS: Waiting times are typically 6-12 months, not years. | Growing Waits: As RTC becomes more popular, provider waiting lists are increasing. |
| Access to Specialists: Connects you with dedicated ADHD specialist teams. | GP Resistance: Some GPs are unaware of RTC or may be reluctant to refer outside the local system. You may need to advocate for yourself firmly but politely. |
| Shared Care Issues: Post-diagnosis, getting a GP to agree to a "Shared Care Agreement" for prescriptions can still be challenging (more on this later). |
For those who cannot or do not want to wait, the private route is the fastest way to get a diagnosis. You can often be assessed within a few weeks of your initial enquiry. However, this speed comes at a significant financial cost.
A private ADHD diagnosis is not a single payment. It's a multi-stage process, and costs can accumulate quickly.
| Stage of Process | Estimated Cost Range | What It Covers |
|---|---|---|
| 1. Initial Assessment | £600 - £2,000+ | A 1.5-2 hour comprehensive diagnostic interview with a consultant psychiatrist. Includes report preparation. |
| 2. Titration Phase | £150 - £400 per appointment | 2-4 follow-up appointments are typical. This is where medication is introduced and the dosage is carefully adjusted (titrated) to find the optimal level for you. |
| 3. Private Prescriptions | £80 - £150+ per month | The cost of the medication itself during the titration phase, before your care is (hopefully) transferred to an NHS GP. |
| 4. Annual Review | £300 - £500 | Most private clinics require an annual review to continue overseeing your care, even under a shared care agreement. |
Total Estimated Cost for Private Diagnosis & Titration: £1,500 - £3,500+
This figure does not include the cost of any additional therapies or coaching you might choose to undertake post-diagnosis. It's a substantial investment and a decision that requires careful financial planning.
This is one of the most common questions we receive at WeCovr, and the answer requires absolute clarity.
In short: No. Standard UK private medical insurance (PMI) does not cover the diagnosis or treatment of ADHD.
This is not a loophole or a hidden clause; it's fundamental to how the insurance model works in the UK.
PMI is designed to cover acute conditions that arise after you take out a policy. An acute condition is one that is curable with treatment and is not long-term (e.g., a cataract, a hernia, joint pain requiring replacement).
ADHD falls into two excluded categories:
No mainstream UK PMI provider—including Bupa, Aviva, AXA Health, or Vitality—offers cover for ADHD assessments or treatment as a standard benefit.
Expert Broker Insight: A common mistake is buying a PMI policy hoping it will grant you a quick ADHD diagnosis. This will lead to a declined claim and disappointment. As your broker, our job at WeCovr is to provide this clarity upfront, ensuring you invest in a policy for the right reasons—to get fast access to treatment for eligible, acute conditions that may arise in the future.
While PMI won't pay for the diagnosis, some premium policies may offer access to mental health support lines or a limited number of therapy sessions for related acute conditions like anxiety or depression, which can co-occur with ADHD. We can help you compare these ancillary benefits.
Whether you go via Right to Choose or fully private, getting your diagnosis is only the first step. The next is securing medication and ongoing care. This is where the Shared Care Agreement (SCA) becomes vital.
This is a huge risk, especially for those going fully private. You could get your diagnosis but be left paying for private prescriptions indefinitely because your GP will not agree to an SCA. It is crucial to have an open conversation with your GP before you embark on a private assessment to gauge their willingness to enter an SCA post-diagnosis.
| Pathway | Cost to You | Estimated Wait Time | Key Advantage | Major Risk |
|---|---|---|---|---|
| Standard NHS | Free | 2 - 7+ years | No financial cost. | The wait is debilitatingly long. |
| Right to Choose (England) | Free | 6 - 12 months | A free and much faster route. | Your GP may refuse referral; shared care can still be an issue. |
| Fully Private | £1,500 - £3,500+ | 2 - 8 weeks | Extremely fast access to diagnosis and treatment. | Very expensive, with a significant risk of no SCA, leaving you with ongoing private prescription costs. |
Your choice depends on three factors: your location (is RTC an option?), your finances (can you afford the private route?), and your urgency (how badly are your symptoms affecting your life?).
While private medical insurance UK is an invaluable tool for skipping waiting lists for eligible acute conditions, it is not the solution for a fast ADHD diagnosis. Understanding its role and limitations is key. At WeCovr, we help clients build a health protection plan that works, providing peace of mind for the unexpected while offering full transparency on what is and isn't covered.
Our clients also benefit from complimentary access to our AI-powered nutrition app, CalorieHero, and receive discounts when they take out multiple policies, such as life and health insurance together.
Navigating the world of healthcare can be complex. While we've established that PMI isn't the route for an ADHD diagnosis, it remains the best way to secure fast, high-quality care for a wide range of other health concerns.
If you want to understand how private health cover can give you and your family peace of mind for future acute health issues, our expert team is here to help. We'll compare policies from leading providers, explain the benefits in plain English, and find a plan that fits your needs and budget—all at no cost to you.
