NHS ADHD assessments are commissioned and funded by your local Integrated Care Board. Due to high demand across England, some ICBs are currently working within agreed annual funding limits, which means your assessment may be subject to a wait even after your referral is accepted.
Your legal right to choose your provider remains protected. We are actively working with ICBs across England to keep our service as accessible as possible and will update our availability as soon as new information comes in.

As of 3 November 2025, NHS South East London ICB introduced a new Adult ADHD Referrals Triage Service, which differs from the standard Right to Choose referral process.
This applies to all adults aged 18 and over registered with a GP in Bromley, Bexley, Greenwich, Lewisham, Lambeth, or Southwark.
The referral process for this ICB is as follows:
Complete your self-report form before your GP appointment.
Bring your completed form to your GP appointment. They will discuss your experiences and confirm whether an ADHD assessment is appropriate.
Your GP will submit a referral to the South East London Adult ADHD Referrals Triage Service via NHS e-Referral Service (e-RS).
The triage team will review your referral and contact you to arrange a short meeting to explain your assessment options, including Right to Choose providers such as ADHD Certify.
If you choose to proceed with ADHD Certify, the triage team will forward your referral to us and you will be added to our waitlist.
Please note that referrals submitted outside of this triage process cannot be accepted and will need to be resubmitted through the correct pathway, which may cause delays to your assessment.
