ADHD in the UK: What Are Your Assessment Options?

If you or someone you care about is struggling with attention, focus, or emotional regulation, getting an ADHD assessment can be a powerful first step toward understanding what’s going on and what might help.

But the path to diagnosis can feel unclear, especially when you're navigating NHS waiting lists, private clinics, or even wondering if your GP will take you seriously.

In this blog, we break down the most common assessment routes in the UK, what to expect, and how to decide what’s right for you.

1. NHS Referrals via Your GP

If you think you might have ADHD, the usual place to start is your GP. They can assess whether a referral to a specialist ADHD service is appropriate. If so, you’ll be added to a waiting list for an NHS assessment - either via a local mental health team or a specialist ADHD pathway.

The pros:

• It’s free.

• You’ll receive a diagnosis and care through NHS services if eligible.

The challenges:

• Waiting lists are long - often 12 to 36+ months depending on location.

• Support while you wait can be limited.

• Some GPs may be unfamiliar with the referral process or hesitant without clear evidence.

Bringing a completed screening questionnaire (like the ASRS) and some examples of how your symptoms impact daily life can help support your case for referral.

2. The NHS Right to Choose (England only)

If you're in England, you may be entitled to ask for an alternative NHS-funded provider under the Right to Choose scheme. This can give you access to ADHD assessment services outside of your local NHS trust - potentially with shorter waiting times.

This option still requires a GP referral, but it gives you more control over where you’re seen. Not all GPs are familiar with the process, so it may help to bring information or links with you.

Note: This applies only to NHS services registered in England and doesn’t include private clinics outside the NHS framework.

3. Private ADHD Assessments

Private assessments are becoming more common for those who want clarity sooner, or who would like a more personalised experience. At Cognition Care, we offer private ADHD assessments for both adults and children, carried out by experienced clinicians following NICE-recommended methods.

Benefits of going private:

• Shorter wait times, typically a few weeks.

• Thorough assessments, including structured clinical interviews and pre-appointment screening.

• Ongoing support, such as medication titration, coaching, or tailored recommendations.

Things to consider:

• You’ll need to self-fund the assessment. Prices across the UK vary but usually range from £500 to £1,200.

• You’ll still need to work with your GP if you want shared care for medication via the NHS.

At Cognition Care, we provide clear documentation to support shared care arrangements when appropriate, and we take the time to explore all options — not just medication — depending on your needs and preferences.

4. What Do NICE Guidelines Say?

The National Institute for Health and Care Excellence (NICE) provides the official UK guidance for ADHD diagnosis and treatment. These guidelines are followed by both NHS and reputable private providers.

Key recommendations include:

• A full assessment using validated tools and clinical interviews

• Gathering information from multiple sources, such as parents, schools, or partners

• Offering evidence-based treatment plans, which may include medication, behavioural support, or coaching

Choosing a provider that follows these guidelines helps ensure your diagnosis is recognised and your care is safe and effective.
