UK Adult ADHD Statistics 2026
This page gathers the most-quoted statistics on adult ADHD in the UK, from estimated prevalence to assessment waiting times and Right to Choose, each drawn from a named primary source. It is a scaffold: figures are added only when a primary source is confirmed and checked. It is information, not medical advice or a diagnosis. Last updated June 2026. Every figure below links to its primary source.
Methodology and sources
Every statistic on this page is taken from a named primary source and links to the original record so you can verify it. We do not republish figures from secondary blogs. The page is reviewed and the figures refreshed on a regular cadence; the "last updated" date reflects the most recent substantive change, not an automated rebuild.
