The two-child limit restricts the child element of Universal Credit and Child Tax Credit to a family's first two children, for children born on or after 6 April 2017. For many families with three or more children, that means much less income. It hits the ability to pay rent and to stay in a home big enough for the family. Here is how the limit works and what support exists.
What is the two-child limit?
Since April 2017, the child element of Universal Credit and Child Tax Credit has been limited to two children. Have three or more children, with the youngest born on or after 6 April 2017? You will not get child element payments for the third or later children.
The limit covers the child element of both benefits. It does not touch Child Benefit, which is paid for every child no matter how many you have.
How does this affect housing?
The practical effect is a big cut in household income. For a family with three children, where the third was born after April 2017, the loss is around £3,455 a year (at 2025 rates) for that third child. For a fourth child, the loss doubles.
When income falls like this:
- Rent becomes harder to afford: Families may fall behind on rent and risk eviction.
- A big enough home becomes unaffordable: Larger families may not manage the rent on a home with enough bedrooms, which leads to overcrowding.
- The Local Housing Allowance may not cover the rent: The housing element of Universal Credit (or Housing Benefit) is based on your area's Local Housing Allowance, with a room allowance linked to your number of children. The two-child limit does not cut the housing element itself. But with less coming in overall, a higher rent is harder to meet.
Are there exceptions to the two-child limit?
Yes. Some children are exempt, and the child element is paid for them even as a third or later child:
Multiple births: If twins or triplets take you over the two-child line, the extra children from that birth are exempt.
Non-consensual conception: A child conceived through rape, or within a controlling or coercive relationship, may be exempt. This is the most sensitive exception. It needs a declaration from a professional (a social worker, your doctor, or a health visitor) confirming the circumstances. The process is confidential.
Adopted or taken-in children: Children adopted from council care, or taken in under certain foster-to-adopt arrangements, may be exempt.
A later multiple birth: If a family with two children goes on to have twins, the children from that twin birth are exempt.
How to claim an exception
Report the exception to the DWP (for Universal Credit) or HMRC (for Child Tax Credit). For the non-consensual conception exception, a professional's confirmation form is needed. You do not have to give details to the DWP or HMRC yourself: the professional's declaration is what counts.
Citizens Advice and welfare rights advisers can help you through this.
What if I am in rent arrears because of the two-child limit?
Has the lost income led to rent arrears, and now the threat of eviction? There are steps you can take:
- Apply for a Discretionary Housing Payment (DHP): If you get the housing element of Universal Credit, or Housing Benefit, you can ask your council for a DHP to top up your rent. See our guide to Discretionary Housing Payments.
- Contact your landlord: Explain your situation in writing and try to agree a repayment plan for any arrears.
- Get welfare rights advice: An adviser can check you are getting everything you are entitled to, and help you apply for exceptions.
- Check your home for disrepair: If your rented home is in disrepair and your landlord has not fixed it, you may have a separate claim, and it could bring compensation.
Overcrowding and rehousing
Families hit by the two-child limit may not manage the rent on a home with enough bedrooms, and overcrowding follows. If your home falls below the bedroom standard, that can raise your priority on the housing register. See our guide to overcrowding and your rights.
When should I contact Support for Tenants?
Support for Tenants helps with housing disrepair claims, not benefits advice. But if you are overcrowded or behind on rent, and your home is also in disrepair, you may have a claim. Call us on 0800 030 4669.
No upfront cost. You only pay if you win, and the fee comes out of the compensation, not your pocket. If you don't win, you pay nothing.
