An ADHD assessment is a specialist evaluation that looks at your attention, activity levels, impulsivity and how these affect your everyday life. It considers your symptoms, personal history and experiences at home, work or in education to determine whether you meet the criteria for attention deficit hyperactivity disorder (ADHD).
Identifying ADHD can help you understand why certain tasks feel difficult and find support that suits your needs. A diagnosis may help you explore treatment options, workplace adjustments or practical strategies for managing daily responsibilities.
Keep reading to discover three ways to get an ADHD assessment in the UK and what to expect from each route.
What Are Your Options for an ADHD Assessment in the UK?
There are three main routes to getting an ADHD assessment in the UK: through the NHS, using NHS Right to Choose if you live in England and are eligible, or booking privately.
Each option has different waiting times, costs and referral requirements, so it’s worth understanding how they work before deciding which is right for you. We’ll explore each of these options below to help you understand what to expect.
1) Get an ADHD Assessment Through the NHS
You usually won’t pay for an NHS assessment, although waiting times depend on your location, age, and local service availability.
Step 1: Book an Appointment with Your GP
Explain the difficulties you experience and how they affect your daily life. You might struggle with concentration, time management, organisation or impulsive behaviour, so give specific examples of what happens at home, work or school.
Your GP may ask about your symptoms, medical history and mental health. If ADHD seems possible, they can refer you to an appropriate specialist service, although the exact referral process differs across the UK.
Step 2: Wait for a Specialist Referral
After the referral, you may need to wait for an appointment with an ADHD specialist. Waiting times vary considerably between services, so ask your GP or the relevant NHS team for an update and an estimate of how long you might wait.
For children and young people, the referral may go to a paediatric service or a child and adolescent mental health team. Adults are generally referred to a specialist mental health or ADHD service.
Step 3: Attend the Assessment
The specialist will discuss your symptoms, developmental history and how your difficulties affect different areas of your life. They may ask about childhood experiences, education, employment, relationships and mental health, as ADHD symptoms generally begin during childhood.
You may complete questionnaires or be asked to provide information from someone who knows you well. The specialist considers this information alongside a clinical interview and other relevant details, as questionnaires alone cannot confirm an ADHD diagnosis.
Step 4: Discuss the Outcome
The specialist will explain whether the findings meet the diagnostic criteria for ADHD. If you receive a diagnosis, they can discuss suitable support, treatment options, and any further appointments you may need.
If you do not receive a diagnosis, ask what might explain your difficulties and whether other support could help.
2) Use NHS Right to Choose in England
If you live in England, you may be able to use NHS Right to Choose to select an eligible provider for your ADHD assessment. This can give you an alternative to your local service, including certain independent organisations that provide NHS-funded care. You do not pay the provider’s private fees when the referral is accepted through this route.
Start by speaking to your GP about whether Right to Choose applies to your circumstances. You can research eligible providers, check which ages they assess, and ask about their waiting times before requesting a referral. The provider must be eligible to accept referrals under the scheme and offer the service you need.
Check what happens after diagnosis before choosing a provider. Some services offer assessment only, while others provide treatment and follow-up care, and medication-prescribing arrangements can differ. A GP is not automatically required to accept a shared care agreement, so ask how ongoing prescriptions and monitoring would be managed.
3) Arrange a Private ADHD Assessment
Before booking, check that the clinician has appropriate qualifications and experience diagnosing ADHD. Ask what the fee includes, how long the assessment takes, and whether you will receive a written report with recommendations. This guide to the cost of a private ADHD assessment can help you understand the expenses to consider when comparing providers.
Make sure you understand the costs of ongoing care as well as the initial appointment. Follow-up consultations, medication reviews and prescriptions may involve additional fees, and your GP may not agree to take over prescribing through a shared care arrangement. Ask the provider who will manage treatment and monitoring if you receive a diagnosis.
The Right Route for Your ADHD Assessment
Getting an ADHD assessment can help you understand your difficulties and explore the support that may make everyday life easier.
The standard NHS route offers assessment without private fees, while Right to Choose may provide an alternative NHS-funded option if you are eligible in England. Private assessment is another route, but you need to consider the initial fee and any ongoing treatment costs.
Before deciding, compare waiting times, provider qualifications and follow-up arrangements. Prepare examples of how your symptoms affect daily life and gather any relevant information about your childhood or education.
