This is a screening tool only - not a diagnostic instrument. It cannot diagnose ADHD. Only a qualified mental health or medical professional can diagnose ADHD after a full clinical evaluation. Use these results as a conversation-starter with your doctor.
An estimated 2.5 million adults in the UK live with ADHD - most undiagnosed.
If your results suggest ADHD, book an appointment with your GP and share your screener results. Under NHS guidelines, your GP can refer you to a specialist ADHD service - though NHS waits can be 1–5 years. Private assessments typically take 2–8 weeks and cost £400–£900. The Right to Choose scheme may allow faster NHS access via private providers.
