What are NHS waits like in London?

NHS England publishes waiting times for sleep studies each month under sleep physiology in its diagnostics dataset (DM01), alongside consultant-led referral to treatment waits for London providers, so you can check the current position for your area before going private.

Do I have to travel into London?

Not necessarily. In-person clinics cluster around Harley Street (W1), the City, Canary Wharf and Chiswick, with growing capacity in Stratford and Croydon. Most clinics are within 10 minutes of an Elizabeth line, Northern line or Overground station. Most specialists also work by video, so you can be assessed from anywhere in Greater London if travelling is difficult.

Can this screening diagnose ADHD?

No. A screening tool can only indicate likelihood. A diagnosis requires a structured clinical interview with a qualified clinician, covering childhood onset, functional impairment and alternative explanations for your symptoms.

What does a private ADHD assessment cost in the UK?

Through Take a Seat specialists, a private adult ADHD assessment runs from £650 to £1,200 depending on the clinician and the complexity of the presentation. Fees are shown on each specialist's profile and paid directly to them.

How long will I wait for a private assessment?

Usually two to four weeks to the initial appointment, with the written report inside 10 working days after it. NHS waits are measured in years across most regions.

Will my GP accept a private ADHD diagnosis?

Generally yes when the clinician is GMC-registered and follows NICE NG87. Whether your GP then takes over prescribing under shared care is at your GP and ICB's discretion, so ask before you book if medication is your goal.

Is my screening data stored?

No. Screening answers are processed in-session to produce your result and are not saved to your record. If you go on to book, you choose what to share on the booking form.
