How to Get Diagnosed with ADHD in the UK

Understanding ADHD and Diagnosis in the UK

If you’ve been struggling with focus, impulsivity, or hyperactivity, you might be wondering if you have Attention Deficit Hyperactivity Disorder (ADHD). Getting a diagnosis can be a game-changer, offering clarity and access to treatment that can improve daily life. But how do you actually get diagnosed with ADHD in the UK?

In this guide, we’ll break down the different pathways available, whether through the NHS or via a private ADHD diagnosis. We’ll also cover your rights, what to expect from an assessment, and what to do if you face barriers along the way.

Step 1: Recognise the Signs of ADHD

Before seeking a diagnosis, it's helpful to understand what ADHD looks like in adults and children. ADHD symptoms typically fall into three categories:

• Inattention (e.g. struggling to focus, forgetfulness, disorganisation)
• Hyperactivity (e.g. restlessness, difficulty staying still, excessive talking)
• Impulsivity (e.g. interrupting conversations, acting without thinking, impatience)

ADHD is often misunderstood and sometimes mistaken for anxiety, depression, or other conditions. That’s why self-education is an important first step. You can use online ADHD screeners to see if your experiences align with ADHD traits.

Step 2: Speak to Your GP

Your GP is the first port of call for getting an ADHD diagnosis in the UK. Here’s how to approach your appointment:

• Prepare in advance – Write down your symptoms, real-life examples, and how they impact your daily life.
• Be honest and detailed – Explain when your symptoms started, how they affect work, relationships, and general well-being.
• Ask about an NHS ADHD assessment – Your GP can refer you to a specialist for a formal assessment.

What If Your GP Refuses a Referral?

If your GP is hesitant or dismisses your concerns, don’t give up. You have options:

1. Request a second opinion – Ask another GP within the same practice.
2. Change GP practice – Use the NHS website to find another GP.
3. Highlight the NICE Guidelines – In England, Wales, and Northern Ireland, NHS ADHD services must be available.
4. Consider a private ADHD assessment – This can be quicker but comes at a cost.

Step 3: Choose Your ADHD Assessment Route

There are three main ways to get an ADHD diagnosis in the UK:

Option 1: NHS ADHD Diagnosis

• Free but has long waiting lists (often 2–3 years in some areas).
• Requires a GP referral to see a psychiatrist, specialist nurse, or psychologist.
• The assessment includes a clinical interview, symptom checklists, and possibly input from family or teachers.
• If diagnosed, treatment options include medication, therapy, or coaching.

Option 2: NHS 'Right to Choose' (England Only)

• Faster than a standard NHS referral.
• Under NHS rules, patients in England can choose an alternative provider if waiting times are excessive.
• Requires a GP referral.
• Some GPs may be unaware of this option, so you might need to advocate for yourself.

Option 3: Private ADHD Diagnosis

• Much faster (appointments within weeks rather than years).
• Can be expensive: £1250+ for adults, £1450+ for children.
• Ensure the clinician is GMC-registered.
• Some NHS GPs may refuse to prescribe ADHD medication based on a private diagnosis, so check before proceeding.

Step 4: What to Expect During an ADHD Assessment

Whether NHS or private, an ADHD assessment usually includes:

1. Detailed interview – The specialist will ask about childhood and current symptoms.
2. DSM-5 criteria assessment – You’ll need to show symptoms have been present since childhood and affect multiple areas of life.
3. Additional input – Reports from family, teachers, or partners may be requested.
4. Possible physical exam – To rule out other conditions that mimic ADHD.

If you’re diagnosed, the clinician will discuss treatment options such as medication, therapy, or coaching.

Step 5: Post-Diagnosis – What Happens Next?

Shared Care with Your GP

If diagnosed via the NHS, you’ll likely be referred back to your GP for ongoing treatment and medication management.

If diagnosed privately, shared care agreements allow some private patients to receive NHS prescriptions. However, not all GPs accept private diagnoses.

Living with ADHD

Getting a diagnosis can be an emotional journey—both a relief and a challenge. The good news is that support is available:

• Join ADHD support groups (e.g. ADHD Foundation).
• Learn about strategies and tools to manage ADHD.
• Consider ADHD coaching, therapy, or lifestyle changes.
