The UK government is working on a welfare overhaul far larger than previously disclosed. At its centre: removing the health element of universal credit for claimants under 25 and replacing the personal independence payment (PIP) claimed by four million people with an entirely new system. The changes would require primary legislation, with a bill expected in the next parliamentary session. The numbers frame the stakes. UK welfare spending has hit £333bn this year. Pensioners receive roughly 55% of that budget; young people including NEETs — but not children — receive about 2.5%. Alan Milburn, leading the review on youth employment, called it "shameful" that the government spends 25 times as much on benefits for young people as it does on supporting them into work. About 184,000 people aged 16-24 currently receive the universal credit health element, already cut to £217 a month for most new claimants from next April. The replacement offer is subsidised jobs, targeted back-to-work schemes, and mental health support — aimed at getting more of Britain's one million 16-to-24-year-old NEETs into the workplace. Denmark's model, which restricts disability pension access for under-40s in favour of flexible jobs and training, is being studied. Officials are also looking at whether a new PIP replacement system would apply to all working-age claimants or only those below a cut-off age such as 50 or 60. Those with the most severe disabilities would be protected from losing money. The political hazard is real. Labour MPs staged a dramatic welfare rebellion last year when the government tried to change PIP eligibility criteria. Ministers have spent weeks trying to persuade backbenchers that this round is about reform rather than cuts, and believe opposition has waned. But the structural problem remains: PIP is a non-means-tested benefit unrelated to employment status, paid to cover the extra costs of disability. Cutting it for younger people doesn't change the costs those people face — it just stops paying for them. The charity sector has already fired warning shots. Scope estimates about half of households with an under-22 receiving the UC health element are already in poverty, rising to more than nine in ten if support is removed. More than 40 leading charities wrote to Milburn and Work and Pensions Secretary Pat McFadden warning that tougher sanctions or cuts risked pushing vulnerable young people deeper into poverty and further from employment. Lucy Schonegevel of Action for Children said cutting disability benefits would be "at odds with the prime minister's recent warning against 'crude cuts'." The competitive dynamic among parties is pushing the debate rightward. Kemi Badenoch's Conservatives would ban under-25s with less than six months' continuous employment from claiming universal credit entirely. Reform UK wants to cut £50bn from the welfare bill and restrict PIP's successor to only the "gravely ill and severely challenged." Labour is positioning itself between these poles — but the direction of travel is the same, and the sequencing is the problem. Benefits are being cut or removed before the replacement infrastructure exists. Milburn's own evidence shows half of young people who move onto disability benefits are still not in work 15 years later, which he calls a "catastrophic failure" — but the proposed solution assumes those people's primary barrier is insufficient motivation rather than insufficient support or insufficient jobs. The Motability scheme is also on the chopping block, with officials returning to the idea of further cuts after already axing £300m in tax breaks. The scheme lets disabled people use PIP to lease cars — a practical mobility solution that becomes irrelevant if the underlying benefit disappears. The government insists it will "always ensure there is a safety net for the most vulnerable," but the definition of "most vulnerable" is doing enormous structural work in these plans, and it's a definition that hasn't been finalised.
