If Labour Only Sub Contractors are eligible for the second and final Income Support Scheme grant, and have been adversely affected on or after 14 July 2020, you can make a claim on or before 19 October 2020. You can claim for the second grant even if you did not make a claim for the first grant. If you have different circumstances it can affect your eligibility. If you’re self-employed or member of a partnership, find out how your circumstances can affect your eligibility for the scheme.
