The Joseph Rowntree Foundation (JRF) has published a replacement version of its briefing on a protected minimum floor in Universal Credit, after the original was published on 9 October 20251. The foundation said the scrapping of the two-child limit in April 2026 changed the policy context and meant the impacts cited in the original briefing were no longer relevant1. It also disclosed that a coding error had been found which affected the poverty impacts in the original briefing, and that this has been corrected in the new version1.
"This new briefing replaces one originally published on 9 October 2025."
JRF said the correction would not have affected the narrative or conclusions of the original briefing, and that all other figures in it would have remained unchanged1. Elements have also been refreshed following publication on 22 September 2026 of the first official benefit cap statistics to reflect the impact of the two-child limit being removed1. JRF said its modelling showed a lower number of households being capped but higher savings per household than the new data implied, that these differences are likely to cancel each other out to some extent, and that costs and impacts should be treated with caution until new modelling is completed1.
The briefing sets out a proposed protected minimum floor below the Universal Credit standard allowance, which would limit the combined effect of debt deductions and benefit cap deductions1. Around half of households receiving Universal Credit have at least one deduction taken from their payment1. The Fair Repayment Rate, introduced from April 2025, caps total debt deductions at 15% of the standard allowance, down from 25% previously, but this limit does not apply to other types of deduction such as the benefit cap1.
JRF said a floor set 15% below the standard allowance would mean a single adult aged 25 or over could not have their standard allowance reduced below £83 a week in 2026/271. It estimated the policy would lift 30,000 additional people out of poverty in 2027/28, three quarters of them children, and protect 130,000 people from very deep poverty, including 100,000 children, at an annual cost of between £600 million and £700 million1. Around 140,000 households would see their Universal Credit payment increase by £80 a week on average1.
The briefing states that around 4 in 5 households who had their Universal Credit reduced by the benefit cap in May 2026 had children, and that households had £80 a week deducted on average because of the cap, with over 25,000 households seeing over £150 a week deducted1. It also cites Department for Work and Pensions estimates that in 2029/30 around 50,000 families would not gain at all from scrapping the two-child limit because they are subject to the benefit cap, and around 10,000 families would only partially gain1.
Why it matters for households
The correction concerns JRF's own modelling rather than the rules households are paid under, so it does not change anyone's award. What it does change is the published estimate of what a protected minimum floor would achieve, and JRF has said the costs and impacts should be treated with caution until its modelling is updated1. The underlying figures on deductions remain: around half of Universal Credit households have at least one deduction, and 62% of households with a benefit cap deduction in February 2026 also had a debt deduction, with around three quarters of those seeing a debt deduction of over 10% of their standard allowance1. The Fair Repayment Rate limit of 15% of the standard allowance applies to debt deductions but not to the benefit cap1. More detail on the limit and who is affected is in the guide to benefits.
What happens next
JRF said it is in the process of updating its modelling following the 22 September 2026 benefit cap statistics, and that costs and impacts should be treated with caution until that work is completed1. No date for the completed modelling has been reported.
