For residents of Sheffield seeking an ADHD assessment, the commissioning body responsible for local NHS services is NHS South Yorkshire ICB, which oversees how referrals are processed and funded across the region. As with many integrated care boards nationally, NHS South Yorkshire ICB has faced significant pressure on its adult ADHD pathway, and local NHS waiting times for a first assessment have been widely reported to stretch beyond two to three years in some cases. Under the national Right to Choose framework, eligible patients in England retain the right to request referral to an approved independent provider, and GPs in Sheffield are generally obliged to honour such requests, though it is worth being aware that some ICBs have introduced administrative steps or gateway processes that can cause delays if not navigated carefully. Before your GP appointment, it is sensible to confirm that your chosen Right to Choose provider is currently accepting new NHS-funded referrals from South Yorkshire, as capacity can change. Arriving with objective evidence of your difficulties — such as a qEEG brain screening report — can meaningfully strengthen your clinical conversation and demonstrate to your GP that your concerns are well-founded.
