Equality Act 2010 definition of disability
Under the Equality Act 2010, a person is considered to have a disability 'if they have a physical or mental impairment, and the impairment has a substantial and long-term adverse effect on his or her ability to carry out normal day-to-day activities’. ‘Substantial' is defined by the Act as 'more than minor or trivial'. An impairment is considered to have a long-term effect if:
• it has lasted for at least 12 months
• it is likely to last for at least 12 months, or
• it is likely to last for the rest of the person’s life.
