There is a number that rarely makes the front pages, yet it sits behind some of the most consequential decisions being made in British households right now. According to the ONS Census 2021 analysis, more than five million people in England and Wales provide unpaid care. A significant proportion of them have reduced their working hours, turned down promotions, or left employment entirely. The unpaid carers UK workforce question is not a welfare issue at the margins. It is an economic rupture happening slowly, quietly, and disproportionately to women.
I’ve spent time looking at the data behind this, and what strikes me most is not the scale, though the scale is extraordinary, but the invisibility. Carer’s Allowance, the main state benefit for unpaid carers, currently pays £81.90 per week. That is less than two days at the national living wage. The expectation, implicit in that figure, is that caring for an ageing parent or a disabled relative is something you simply absorb. A background cost. A private matter. The reality, for hundreds of thousands of working-age adults, is a career ended prematurely and a pension pot left almost empty.
What the numbers actually show
The 2021 census recorded 5.7 million unpaid carers in England and Wales, down from 5.8 million in 2011, though researchers at Carers UK suggest this undercounts the true figure substantially because many people do not identify themselves as carers at all. They simply see it as looking after someone they love. What the census does capture is intensity: around 1.3 million people provide more than 50 hours of unpaid care per week. That is more than a full-time job, with no contract, no sick pay, no employer pension contribution, and a weekly state benefit that would not cover a modest weekly shop.
Britain’s demographic trajectory makes this more urgent, not less. The ONS projects that by 2045, the number of people aged 85 and over in the UK will have more than doubled compared to 2020. Dementia alone affects around 900,000 people in the UK today; the Alzheimer’s Society estimates that figure will reach 1.6 million by 2040. The demand for care is rising sharply. The workforce to deliver it formally, through paid social care, remains chronically underfunded and understaffed, which is something I’ve covered in depth when looking at the strain on NHS primary care. The gap gets filled by family members, most of whom had other plans for their forties and fifties.
The gendered toll that nobody wants to say plainly
The data on who carries this burden is unambiguous. Women make up roughly 58% of unpaid carers in the UK, and they are more likely to be providing the most intensive care. They are also more likely to reduce paid working hours rather than give up work entirely at first, which means the financial damage accumulates gradually, in a way that feels manageable until it very suddenly isn’t. The lost pension contributions, the missed salary increments, the gaps in National Insurance records, none of these register dramatically in the moment. They arrive as a reckoning later, typically in retirement.
This connects directly to a wider pattern already being felt across British employers. As I noted in a recent piece on Britain’s ageing workforce, roughly one in three employees is now over fifty. Many of those workers are simultaneously managing caring responsibilities for elderly parents. The term used in policy circles is “sandwich generation”, people caught between raising their own children and caring for older relatives. The phrase is almost chirpy. The reality is a demographic pressure point that no employer retention strategy currently addresses adequately.
Carers UK’s 2023 State of Caring report found that 72% of carers said caring had a negative impact on their financial situation, and more than a quarter had given up work altogether. Of those who gave up work, the majority cited the impossibility of managing full-time employment alongside care responsibilities without any meaningful state support to bridge the gap. Not inflexibility. Not unwillingness. Impossibility.
Why Carer’s Allowance is not fit for purpose
The current structure of Carer’s Allowance has a feature, I’d call it a flaw, that actively punishes those who try to remain in part-time work. You can earn up to £151 per week net before losing the benefit entirely. There is no taper. Earn £152 and you receive nothing. This cliff edge design means that a carer who picks up a few extra shifts in a month can find themselves worse off than if they had stayed home. The DWP has been aware of this problem for years. Progress on reforming it has been glacial.
In 2024, the government announced a review of Carer’s Allowance following a scandal over overpayments, thousands of carers had been unknowingly paid benefit while their earnings technically exceeded the threshold, leaving them with unexpected debts to HMRC in some cases. The review acknowledged the cliff edge as a genuine problem. Concrete reform, as of 2026, remains pending. Meanwhile, the earnings threshold has not kept pace with wage growth, making the effective trap wider than it was a decade ago.
The economic cost of doing nothing
There is a straight-line argument here that even the most fiscally conservative reader should find compelling. Carers UK estimates that unpaid carers save the British economy approximately £162 billion per year in care that would otherwise have to be provided formally. That figure, which the organisation derived by valuing caring hours at the national living wage, is larger than the entire NHS budget. We rely on unpaid carers structurally, not incidentally. Paying Carer’s Allowance at its current rate while expecting this army of people to quietly manage is a bargain the state is striking almost entirely on its own terms.
The knock-on effects extend further. Working-age people who leave the labour market to care are not just lost to employers now; they often find re-entry extremely difficult. Skills atrophy. Confidence takes a hit. Gaps on CVs generate questions that few hiring managers handle well. The result is a cohort of experienced, capable people, again, disproportionately women, who end up dependent on state benefits they would not otherwise have needed, at a cost to the Treasury that exceeds what genuine reform of Carer’s Allowance would have required.
The broader housing and planning context matters too. Policies that affect where older people can live, including the housing constraints slowing new development in many parts of England, also shape whether multi-generational living arrangements are even possible. A family that might absorb a caring role more easily if they could live in proximity to an elderly relative finds itself stymied by a planning system that cannot provide the homes. The pressures interact in ways that policy rarely acknowledges.
None of this resolves cleanly. But the first step is refusing to treat unpaid caring as a private choice with private consequences. It is a public good being funded by the private sacrifice of millions of people, most of them women, most of them getting quietly poorer as a result. The unpaid carers UK workforce figures are not a welfare statistic. They are an economic indictment.
