“You’re disabled under the Equality Act 2010 if you have a physical or mental impairment that has a ‘substantial’ and ‘long-term’ negative effect on your ability to do normal daily activities.
The Equality Act 2010 doesn’t apply to Northern Ireland.
What ‘substantial’ and ‘long-term’ mean
‘substantial’ is more than minor or trivial, eg it takes much longer than it usually would to complete a daily task like getting dressed
‘long-term’ means 12 months or more, eg a breathing condition that develops as a result of a lung infection“
