A limit to the support provided by the child element of Universal Credit (and tax credits). The limit means the Universal Credit applicable amount recognises only the two eldest children in a household so that only the first two children receive the child element. This has a knock-on effect on council tax reduction award for Universal Credit claimants. This limit only applies to third (or subsequent) children born after 6 April 2017. This limit is not applied to council tax reduction award for those receiving legacy benefits in but is incorporated in the council tax reduction award calculations for Universal Credit claimants.
