Referrals into our service
GPs and any health professional from within Nottinghamshire Healthcare NHS Foundation Trust can refer to our service.
We are unable to accept self referrals, referrals from third sector organisations or referrals for residents outside of Nottinghamshire.
Those who may be eligible to use our service include:
- Adults aged 17.5 years of above with, or suspected of having, autism and/or ADHD and associated impairment
- Adults aged 17.5 years or above with an ADHD diagnosis who require ADHD medication treatment initiation or review
- Living within Nottingham City or Nottinghamshire County

- Do not have an additional mental illness (these referrals should be made to the Locality Mental Health Team)
Assessment Standards
NeSS follows assessment standards as outline below for autism and ADHD assessment. These are based on nationally agreed standards (such as the NICE guidelines for ADHD and autism assessments and the UKAAN adult ADHD assessment quality assurance standards).
We follow these standards in our own assessments processes and when reviewing referrals into the service for post diagnostic support or ADHD medication.
If you are planning to access a Right to Choose or private diagnostic assessment for autism or ADHD, please ensure that the provider is able to follow these standards or it may not be possible for NeSS to accept future referrals for medication or support.
