There is no published national ADHD waiting time. NHS England recorded up to 803,658 open referrals in England that may have related to an ADHD assessment as of March 2026. This is a count of open referrals, not a validated waiting list, and waiting times vary significantly by area.
At Harley Street Mental health, we recognize the importance of listening to our patients concerns with a view to continue to improve the quality of our services.
We assure you that raising a complaint will not harm or prejudice the care you, or the person you care for is given, but will rather help us improve our service and ensure that we get things right next time. It also gives us the opportunity to rectify the situation.
If you are unhappy with any aspect of our service, then please contact us on complaints@hsmh.co.uk once we receive a complaint, we will speak to the staff and clinician involved to find out what has gone wrong, and then work with you to see how things can be resolved. We aim to respond to complaints within 30 days except in exceptional circumstances.
If you are unhappy with our response for any reason, then we will have the complaint reviewed by our medical director and seek the best solution.
