For residents of Cambridge seeking an ADHD assessment, NHS Cambridgeshire and Peterborough ICB currently commissions the local NHS pathway, where waiting times for a formal assessment can extend to several years in many cases, reflecting a national picture of significant demand outstripping capacity. Under the NHS Right to Choose framework, eligible patients registered with a GP in England retain the legal entitlement to request a referral to an alternative qualified provider, and whilst NHS Cambridgeshire and Peterborough ICB has not publicly announced a blanket restriction on Right to Choose ADHD referrals at the time of writing, individual practices may apply informal triage steps or request supporting evidence before processing such a request, so it is worth confirming your GP surgery's current position in advance. Before your appointment, it is sensible to prepare a clear written summary of how your symptoms affect daily functioning across multiple settings, including work, relationships, and sleep, as this helps your GP assess clinical need efficiently. Bringing objective supporting evidence, such as a quantitative EEG brain screening report from a registered clinician, can meaningfully strengthen your case during that referral conversation.
