How Can I Get Assessed for ADHD in the UK as an Adult?

Getting assessed for Attention Deficit Hyperactivity Disorder (ADHD) as an adult in the UK can be a confusing and overwhelming process. Still, it's important to know that several options are available.

One of the first steps in getting assessed for ADHD as an adult in the UK is to speak with your GP. Your GP can provide information about the disorder and suggest ways to get assessed. If your GP determines that you may have ADHD, they will write you a referral to a specialist, such as a psychologist or a psychiatrist who specialises in ADHD evaluations.

Once you have a referral, you'll be able to get an ADHD assessment one of two ways.

The first option for getting assessed for ADHD as an adult in the UK is through the National Health Service (NHS). The NHS provides ADHD assessments for eligible individuals seeking a more accessible and cost-effective option.

The second option is private clinics that offer ADHD assessments. These clinics generally provide more comprehensive evaluations and can offer a quicker diagnosis than the NHS. However, they can be quite costly.

Regardless of your route, it's important to be honest and open with the professional conducting your testing. Providing them with as much information as possible about your symptoms, behaviours, and medical history will help them make an accurate diagnosis.

It's also important to remember that getting assessed for ADHD is the first step. After your assessment, you may be recommended for treatment, which can include ADHD medication, therapy, or a combination of both.

What Types of ADHD Testing Are There?

ADHD testing is an important tool for diagnosing Attention Deficit Hyperactivity Disorder in children and adults. The most common type of ADHD test used to diagnose the disorder is the QB Test or Quotient Behavioral Test. This test measures a person's ability to pay attention, stay focused and concentrate on tasks by tracking their behaviour over a period of time. The DIVA (Developmental Inventory for Visual-Motor Assessment) has also been developed as an alternative form of ADHD testing specifically designed for adults.

The QB Test involves computerised activities and paper-and-pencil tasks that must be completed within a certain time frame. The patient's data is then compared against established norms based on age, gender, and other factors to determine if symptoms of ADHD are present.

Other ADHD tests can include the Conners' Adult ADHD Rating Scale and the Brown Attention-Deficit Disorder Scales, which give a detailed assessment of a patient's behaviour. These tests are meant to be used by healthcare professionals, who can then determine if ADHD is present or not.

If you think you might have ADHD, take our self-assessment today to see whether or not you present key symptoms.

How Long is the NHS Waiting List for an ADHD Assessment?

The NHS offers ADHD assessments to eligible individuals and provides a more accessible and cost-effective option. An ADHD assessment through the NHS is typically conducted by a specialist such as a psychologist or a psychiatrist and can be done through a referral from your GP.

However, these services are often under-subscribed, and it can be difficult to get an appointment due to long waiting lists in some areas, so it may take some time to receive a diagnosis and begin treatment.

Statistics show that, on average, it takes around two to three years for people with ADHD to receive an assessment and appropriate treatment through the NHS. The time to receive treatment depends on which part of the UK you live in, as waiting lists vary across different localities.

In some parts of England, referral times are shorter than two years but still significantly longer than other services such as mental health counselling or physiotherapy. And in some places, that time frame could be as high as seven years! This lengthy wait can be extremely difficult and frustrating for those affected by this condition.

How Much Does a Private ADHD Test Cost in the UK?

On the other hand, private ADHD assessments are typically conducted by private clinics and are paid for by the individual or their insurance. Private assessments are generally more comprehensive and can provide a quicker diagnosis than the NHS.

Private assessments also allow for a more personalised approach, as you can choose a specialist who best meets your needs and can offer a more private and confidential setting. However, private ADHD assessments can be expensive, and may not be covered by insurance, so it's important to consider your budget when deciding between private and public options.

The cost of a private ADHD test in the UK can range significantly. Factors such as the testing centre's location, whether it’s done at home or at a clinic, and the assessment tools used will all affect the price. Some tests may be more expensive than others due to specialists being involved with complex assessments.

Generally speaking, you should expect to pay anywhere from £500-£2000 for an initial screening session with a qualified psychologist.

Where Can I Find an NHS or Private ADHD Assessment Near Me?

Below we have collected information on where you can get assessed for ADHD across the UK both through the NHS and privately. For the private locations, we've also included the cost of an initial assessment so you can see the comparison. Please remember that you almost always must have a referral from a GP or psychiatrist to be assessed.

It's also important to note that since 2018 if you are registered with a GP surgery in England, and a GP refers you to an appropriately qualified healthcare professional, you have the right to choose the provider to whom you are referred, as long as that provider is providing that service in other parts of England.

However, if you are registered with a GP in Northern Ireland, Scotland or Wales, this does not apply. In Northern Ireland, you are referred to a mental health service by your GP or Health and Social Care Trust. You may be able to choose which service you want to go to, but this is not guaranteed.

ADHD Assessments Online

If you believe you have undiagnosed ADHD and are looking for an assessment, it's worth considering the option of online assessments available in the UK. With the NHS waiting lists for ADHD assessments becoming longer and private assessments being costly, online assessments can be a convenient option.

Trying to get an ADHD diagnosis can be frustrating if you are not receiving the help you need. But while there is no quick fix, there are things you can do to manage symptoms like focus and attention issues to improve your life.

Is it Worth Getting an ADHD Diagnosis?

The UK has seen an increase in the number of people being diagnosed with ADHD. However, with many still undiagnosed, it’s important to consider whether or not a diagnosis is worth it.

As adult ADHD can often be difficult to diagnose, and symptoms tend to vary from person to person, getting an accurate diagnosis is key. It's the only way to ensure you receive appropriate treatment.

A diagnosis of ADHD can clarify why you may have been experiencing certain issues and behaviours throughout your life. It also enables you to access treatments and therapies to help you manage or overcome these difficulties.

This can include medication and psychological interventions such as cognitive behavioural therapy or lifestyle modifications like improving diet and exercise habits.

How to Manage Your Focus and Attention Issues While You Wait 

Waiting for an ADHD assessment can be a challenging and stressful time. I understand this firsthand as a life coach for people with ADHD, as I also struggled with ADHD symptoms before being diagnosed later in my thirties. Whether you're waiting for a diagnosis through the NHS or saving up for a private assessment, it can feel like time is standing still.

During this waiting period, it's crucial to take care of yourself both physically and emotionally. It's important to keep a record of your symptoms, educate yourself about ADHD, and seek additional support. These steps can help you manage your symptoms and improve your quality of life while you wait for your assessment.

As someone who has been through this waiting process myself, I would like to share what helped me manage my focus and attention during that time - natural supplements.

That's right; I took natural food supplements to help me focus, pay attention and ultimately get more done. And let me tell you, the one that worked best was Brainzyme® FOCUS™, a range of natural focus supplements.


I highly recommend these products, as they contain plant-powered ingredients that have been scientifically proven to support concentration, cognition, energy, memory, and mental performance. This means that if you suffer from, focus and attention issuesBrainzyme® FOCUS™ could help.
