Why Choose The Spectrum Clinic?

• Screen Before You Commit: A £99 initial screening, so you are not committing £1,250 before knowing whether a full assessment is the right step
• Objective Testing: QbCheck used alongside validated rating scales and clinical assessment
• Psychologist-Led: A team of licensed clinical psychologists led by Dr Antonietta Pirillo
• Report Turnaround: Reports typically delivered within 4 to 6 weeks of starting the process
• Therapy Priced: Psychology sessions at £130 after diagnosis
• Combined Assessment: ADHD and autism assessed together at £2,850, rather than as two separate pathways

Assessment Process

Assessment uses QbCheck and validated rating scales alongside clinical assessment by a clinical psychologist, with a report typically delivered within 4 to 6 weeks of starting. The specific rating scales used are not named — ask when you enquire.

After Diagnosis

The clinic lists ADHD prescribing services and ADHD therapy alongside assessment, though prices for these are not published and our record does not currently show it as a prescribing service. Confirm directly with the clinic whether medication can be started and managed there, and what it costs.

Right to Choose

The Spectrum Clinic does not accept NHS Right to Choose referrals, so assessment here is self-funded or through insurance.
