Two-Child Benefit Limit Removed From April: Who Benefits and by How Much

The removal of the two-child benefit limit from April 2026 represents the most significant expansion of the child benefit system in over a decade, potentially lifting hundreds of thousands of children above the relative poverty line by extending child tax credit and universal credit payments to third and subsequent children in families where they had previously been excluded.

The restriction, introduced by the Conservative government in 2017, had barred parents from claiming the child element of universal credit or child tax credit for any third or subsequent child born after April 2017, with limited exceptions for multiple births and children born as a result of non-consensual conception. Critics argued from the outset that the policy was arbitrary, punitive towards children who had no agency over the size of their families, and disproportionately harmful to certain ethnic and religious communities where larger families are more common.

Around 1.6 million families with three or more children stand to benefit from the change, with an average financial gain per eligible family estimated at between £3,000 and £4,000 per year for those receiving the full entitlement. The total additional government expenditure is significant, running into the billions of pounds annually, and the change was funded in part by the revenue-raising measures announced in the October 2025 budget.

Child poverty researchers welcomed the change as the single most impactful measure available to the government for reducing child poverty in the near term, noting that families with three or more children face consistently higher rates of material deprivation than smaller families and that the benefit limit had been a primary driver of the rise in child poverty rates recorded over the past eight years.
