In the vast majority of cases, yes. A private ADHD diagnosis from a CQC-registered clinic conducted by a GMC-registered consultant psychiatrist is a valid clinical diagnosis. Your GP cannot legally override it. What GPs can decline is a Shared Care Agreement — the arrangement where your GP takes over prescribing ADHD medication on behalf of your private consultant. Most GPs do accept shared care, but it is not guaranteed and varies by practice. At Harley Mind Care we can provide full shared care documentation with your diagnosis to make this process as straightforward as possible for your GP. If your GP declines shared care, your consultant can continue prescribing privately, and we can advise you on how to escalate a refusal if needed.
