What Does a Private ADHD Diagnosis Include?

Our ADHD diagnostic process is detailed and structured to ensure accuracy and clarity. Every assessment includes:

Pre-assessment screening (ASRS for adults / SNAP IV for children)
90-minute clinical assessment with a qualified ADHD specialist
DIVA-5 evaluation and detailed developmental history review
11–13 page diagnostic report outlining findings and recommendations
Free follow-up consultation to discuss results
Advice on next steps, including GP referral guidance for shared care or medication

All assessments are conducted by a multi-disciplinary team and follow evidence-based guidelines recommended by NICE.

ADHD Diagnosis for Adults

ADHD doesn’t only affect children. Many adults go through life undiagnosed, often attributing symptoms to stress, anxiety, or poor memory. If you’ve noticed challenges with focus, time management, or emotional regulation, a private ADHD diagnosis can offer life-changing clarity.

Signs of adult ADHD may include:

Struggling to complete tasks or maintain focus
Chronic lateness or disorganisation
Impulsive decisions or speech
Difficulty maintaining relationships or managing emotions
Restlessness or racing thoughts

Our adult ADHD assessments explore your developmental history, current challenges, and daily functioning—providing a thorough understanding of whether ADHD is present and how to move forward.

ADHD Diagnosis for Children & Teens

Children and teens with ADHD often face challenges in school, at home, or with peers. Recognising the signs early can be key to building a support plan that helps them succeed. Our ADHD diagnosis for children is age-appropriate, supportive, and involves input from both parents and teachers where necessary.

Symptoms in young people can include:

Difficulty sitting still or following instructions
Frequent daydreaming or losing track of tasks
Emotional outbursts or trouble making friends
Forgetfulness and lack of organisation
Disruptive behaviour in structured environments

Our team works closely with families to ensure the child feels supported throughout the process. We provide recommendations for school accommodations, therapy options, and home strategies.

How Much Does a Private ADHD Diagnosis Cost?

We believe in transparent, fair pricing with no hidden fees. Our private ADHD diagnosis service is priced at:

£500 for a full ADHD assessment (child or adult)
£100 for optional 45-minute follow-up support sessions
£50 travel charge for home visits in the Doncaster area (if requested)

Flexible payment options are available. We’ll never recommend a full assessment unless the screening suggests it’s appropriate.

Diagnosis vs Screening – What’s the Difference?

It’s important to understand the distinction between an ADHD screening and a full diagnosis

SCREENING

A free, brief questionnaire (ASRS or SNAP IV) used to indicate whether further assessment may be needed. This is not a medical diagnosis.

DIAGNOSIS

A formal evaluation carried out by qualified clinicians using clinical interviews, developmental history, and validated tools. It results in a written diagnostic report that can be used to access treatment and support.

We offer both. Our free screening helps you avoid unnecessary assessment costs. If indicated, we’ll guide you through the next steps toward diagnosis.
