Since the UK Labour government took office in summer 2024, calls have intensified to scrap both the “two-child limit” – which restricts support for children through universal credit to two children – and the overall benefit cap. With Chancellor Rachel Reeves resisting this pressure as she tries to manage deteriorating public finances, ways of tweaking the two-child limit policy have been proposed.

But as researchers of child poverty, we have no doubt that the best place to start reducing the high and rising numbers of children growing up in poverty in Britain today is by fully abolishing the two-child limit and the benefit cap.

We argue that both policies are astoundingly unfair. As our four-year research programme has documented, both are causing wide-ranging harm to children. They restrict children’s everyday experiences and damage their ability to thrive – which in the long run affects everyone in the UK.

Children live in poverty because their families don’t have an adequate income. This is partly a simple question of maths: wages don’t adjust when there are more mouths to feed. It’s also partly because things happen unexpectedly for some families – job loss, disability, relationship breakdown – leaving them needing extra support for a period of time.

Countries across Europe respond to these dual challenges by providing financial support that adjusts to family needs. Until recently, the UK did too. Indeed, the UK welfare state was one of the pioneers of “family allowances” in the post-war period.

But since 2017, the UK has reformed the system so that in families with three or more children, the support on offer when things go wrong deliberately and explicitly falls far short of what is needed. The UK’s two-child limit, an approach that differs to other countries in Europe, restricts means-tested support to two children in a family only. It bakes child poverty into the fibre of the UK.

Its sister policy, the benefit cap, limits the maximum benefit amount available to households without adults in work. This removes further help from some of the most vulnerable.

Struggling to get by

The parents we spoke to frequently talked of difficulties in affording basic necessities for their children, including clothes and food. Many parents had resorted to using foodbanks or cut back on food spending.

The material impacts also affected children’s education and their social and emotional wellbeing. Jessica is a single mum of four. Her business went under during the pandemic and her partner left the household, leaving her affected by both the two-child limit and the benefit cap.

When a hole appeared in Jessica’s daughter’s school shoes, there was no money to replace them straight away. Her daughter went to school wearing trainers and was put in isolation for not adhering to the dress code. Jessica explained:

I got the phone call to say she had to go into isolation and, and things and I just said, “I’m not the type of person that just has £20 sat in the bank” … it was kind of a bit public shaming her really, taking her away and putting her in isolation.

Our interviews also showed that, despite parents’ best efforts to shield them, children are often aware of household financial hardship and in turn try to protect their parents. Christina, a mum of three affected by the two-child limit, said of her middle child:

He won’t say he needs new clothes and he won’t say his shoes don’t fit anymore … I think he’s got it into his head now that we can’t go out and spend or he can’t ask, and I feel so bad for that.

Our research also documents the importance of abolishing the benefit cap alongside the two-child limit. Otherwise, some families affected by the two-child limit won’t see much financial gain, while others will be newly pushed into the benefit cap.

Complete removal

Suggested alternatives to the full abolition of the two child limit include a “three-child limit”, or an exemption for children under five. These options would undoubtedly help some families, but would leave many of those in the greatest need still struggling.

Pound for pound, a three-child limit is less effective at reducing poverty than simple abolition, precisely because it is less well targeted on those in deepest poverty. An exemption for under fives would create a new cliff edge, removing significant support on a child’s fifth birthday, even though we know that the costs of children rise as children get older.

Further, these approaches continue to enforce a separation between what a family needs and its entitlement to support, and therefore will continue to embed child poverty as an institutional feature of our social security system. Children’s life chances will continue to be circumscribed by the number of siblings they have. Given what we know about the long-term costs of child poverty for society, these are short-sighted ways to save money today.

It is very encouraging that the government has committed to a child poverty strategy, and that the prime minister has said he will be “laser focused” on tackling child poverty.

But, as we wait for the strategy to be published, the number of children harmed by the two-child limit rises daily. Nearly two-in-five larger families are now affected and this is predicted to rise to 61% of larger families by the time the two-child limit has full coverage.

If the child poverty strategy is to have real impact, its starting point is straightforward: both the two-child limit and the benefit cap need to go, and urgently, before more damage is done to children’s lives.
