The two-child limit restricts the child element of Child Tax Credit and Universal Credit to a family's first two children for children born on or after 6
On this page
The two-child limit restricts the child element of Child Tax Credit and Universal 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, this means significantly less income, with direct consequences for being able to pay rent and stay in suitable housing. Here we explain how the limit works and what support is available.
What is the two-child limit?
Since April 2017, the child element within Universal Credit and Child Tax Credit has been limited to two children. If you have three or more children and your youngest child was born on or after 6 April 2017, you will not receive child element payments for the third or later children.
The limit applies to both Universal Credit (child element) and Child Tax Credit (child element). It does not affect Child Benefit, which is paid for all children regardless of how many you have.
How does this affect housing?
The practical effect is a significant reduction in household income. For a family with three children (where the third was born after April 2017), the loss is around £3,455 per year (at 2025 rates) for the third child. For a fourth child, the reduction is doubled.
When household income is reduced in this way:
- Rent becomes harder to afford: Families may fall behind on rent and risk eviction.
- Suitable housing becomes unaffordable: Larger families may not be able to afford properties with enough bedrooms, leading to overcrowding.
- The Local Housing Allowance may not cover rent: The housing element of Universal Credit (or Housing Benefit) is based on the Local Housing Allowance for your area, which covers a room allowance linked to the number of children. The two-child limit does not reduce the housing element, but the overall income reduction makes affording higher rents harder.
Are there exceptions to the two-child limit?
Yes. Some children are exempt from the two-child limit and will have child element paid even if they are a third or later child:
Multiple birth exception: If a multiple birth (twins, triplets) takes you over the two-child threshold, the additional children from that birth are exempt.
Non-consensual conception exception: A child conceived as a result of rape or in a controlling or coercive relationship may be exempt. This is one of the most sensitive exceptions and requires a declaration completed by a professional (such as a social worker, doctor, or health visitor) confirming the circumstances. The process is confidential.
Adopted or taken-in children: Children who are adopted from local authority care, or taken in by a family under certain foster-to-adopt arrangements, may be exempt.
Sequential multiple births: If a family of two goes on to have twins, all subsequent children from the twin birth are exempt.
How to claim an exception
You need to report the exception to DWP (for Universal Credit) or HMRC (for Child Tax Credit). For the non-consensual conception exception, a professional confirmation form is required. You do not need to provide details to DWP or HMRC directly, the professional's declaration is what counts.
Citizens Advice and welfare rights advisers can help you navigate this process.
What if I am in rent arrears because of the two-child limit?
If reduced income has led to rent arrears and you are facing eviction, there are several steps you can take:
- Apply for a Discretionary Housing Payment (DHP): If you receive the housing element of Universal Credit or Housing Benefit, you can apply to your council for a DHP to top up your rent. See our guide: /help-centre/discretionary-housing-payment-explained.
- Contact your landlord: Explain your situation in writing and try to agree a repayment plan for any arrears.
- Get welfare rights advice: A welfare rights adviser can check you are receiving everything you are entitled to and help you apply for exceptions.
- Check whether your home has any disrepair: If you rent a home that is in disrepair and your landlord has not fixed it, you may have a separate disrepair claim that could result in compensation.
Overcrowding and rehousing
Families affected by the two-child limit may be less able to afford homes with enough bedrooms, leading to overcrowding. If your home is below the bedroom standard, this can affect your priority on the housing register. See our guide: /help-centre/overcrowding-your-rights.
When should I contact Support for Tenants?
Support for Tenants helps with housing disrepair claims, not benefits advice. But if you are in overcrowded housing 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. If you don't win, you pay nothing.
