Yes, usually. ADHD is a disability under the Equality Act 2010 when it has a substantial, long-term effect on everyday activities, which it commonly does for a diagnosed child. The impact matters, not the label.
What the Equality Act 2010 actually says
A person is disabled if they have a physical or mental impairment that has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities. "Substantial" means more than minor or trivial. "Long-term" means it has lasted, or is likely to last, at least 12 months. ADHD is a recognised mental impairment, so the real question is almost never whether ADHD "counts" - it is whether the effect on your child is substantial.
That test covers England, Scotland and Wales. In Northern Ireland the equivalent law is the Disability Discrimination Act 1995, which uses the same broad approach.
Why ADHD is not "automatically" a disability
There is no official list of conditions that qualify on diagnosis alone (only HIV, cancer and multiple sclerosis are treated that way). ADHD is judged on its impact. A diagnosis on its own does not settle it, but it is strong evidence that the impairment has a substantial effect. For most children diagnosed with ADHD, who by definition show significant impairment across more than one setting, the threshold is met. A 2025 Employment Appeal Tribunal case, Stedman v Haven Leisure, confirmed that a substantial effect on even one day-to-day activity is enough.
Why the label matters less than you think
You do not need the "disability" label, or even a diagnosis, to get most support. Schools must use SEN Support for any child whose ADHD affects their learning, and Disability Living Allowance (DLA) for children is decided on care and mobility needs, not on a diagnosis. Where the label does carry real weight is in the legal duties it switches on:
- Schools and colleges must make reasonable adjustments so an ADHD child is not put at a disadvantage.
- It supports exam access arrangements, such as extra time.
- It protects your child from disability discrimination, including being excluded or treated unfavourably because of ADHD-related behaviour.
- For older teens and adults, employers owe the same adjustment and non-discrimination duties at work.
