Since 6 April 2017 families with third and subsequent children born on or after this date are able to claim additional support through Child Tax Credit or Universal Credit for their first two children only. This maximum support will also apply to entirely new claims to Universal Credit on or after 1 February 2019, regardless of the date of birth of their children.
Claimants that are already receiving support for those born before 6 April 2017 will continue to do so. If they subsequently move to or reclaim Universal Credit (following a break in claim of less than 6 months) they will receive the child element for the same number of children they were previously. This will apply both if they naturally migrate following a significant change of circumstances or are moved as part of managed migration, so long as they remain responsible for the same children.
