In the UK, the definition of disability is given in a law called the Equality Act 2010.
Under the Equality Act, a person is disabled if they have a “physical or mental impairment that has a ‘substantial’ and ‘long-term’ negative effect on your ability to do normal daily activities”.
The definition of a disability has lots of elements but, in short, whether a person is disabled under UK law tends to be determined by the size of the impact – as well as how long the impact will last – on a person’s ability to do everyday activities.
It tends to be viewed as opposite to the Social Model of Disability.
