The £184 Billion the UK Doesn't Pay For: Unpaid Carers and Their Health

Unpaid carers — the family members and friends who look after someone who is older, ill or disabled — hold up the health and social care system. There are millions of them, the care they give is worth more than the NHS budget, and it comes at a measurable cost to their own health.

Most of them never chose the word "carer" and many would not use it about themselves. They are a daughter helping her mother wash and dress before work, a husband learning to manage medications and hoists in the middle of the night, a teenager cooking and translating for a disabled parent, a friend who quietly took on more and more until it became everything. The work is done out of love and duty, at kitchen tables and bedsides, in the hours when the professional system has gone home. It is the largest care service in the country, and it is almost entirely unpaid, unseen and unsupported.

An invisible workforce

The 2021 Census counted 5.8 million unpaid carers in the UK. The economic value of their care has been estimated at around £184 billion a year — more than the entire NHS budget.

Sit with that comparison. If every unpaid carer stopped tomorrow, the state would have to find more than the NHS spends in a year to replace them — and it could not, because there is no spare workforce waiting to take over. This vast contribution rarely appears in a budget line or a spending review, precisely because it is free. That invisibility is the problem: a service the country cannot function without is treated as though it costs nothing, because the cost is quietly absorbed by the carers themselves.

The cost to carers' health

Caring, especially for long hours, takes a toll. Around 1 in 4 carers report their own health as "not good", against fewer than 1 in 5 people who are not carers.

A gap like this is not a coincidence of who happens to be caring. It is what caring does when it comes without rest or backup: the lifting that wears down a back, the broken nights that erode everything, the appointments a carer cancels for themselves so they can keep someone else's, the anxiety that never quite switches off. Many carers describe running down their own health to protect the person they love — and then finding that when they finally fall ill, there is no one to step in.

What this means day to day

The day-to-day reality is a series of small sacrifices that add up to a shrinking life. It is dropping to part-time hours, or leaving paid work altogether, and watching income and pension fall away just as costs rise. It is friendships that fade because there is never a free evening, and holidays that stop happening because there is no one to take over. It is the constant low hum of worry — about money, about what happens if the caring gets harder, about who would look after their person if they themselves went into hospital. Much of this is invisible to the outside world, which is exactly why it is so easy for policy to overlook.

None of this is inevitable. Carers are not fragile by nature and their struggles are not a personal failing to be managed with more grit. The harm is structural: it comes from a system that leans on their free labour while offering too little in return — too few breaks, too little recognition, too little practical and financial support, and too little attention to the carers' own health needs.

Why it matters

The number providing substantial, high-hour care has grown, and it is that intensive caring that most damages carers' health, work and finances. Supporting carers — with breaks, recognition and their own healthcare — is both a wellbeing issue and a way of protecting the care millions of others rely on.

There is a hard logic here that ought to concentrate minds: when a carer's own health collapses, the person they were looking after usually falls straight onto the formal system, at far greater cost and often in crisis. Protecting carers is not charity — it is the most efficient investment the health and care system could make in its own stability. A break, a proper carer's assessment, a check-up that actually happens, a bit of financial security: these are the things that keep the second health service standing.

Why we're publishing this

Health Insurance UK is a commercial health-insurance resource, not a charity. We gathered these official figures because the carers' organisations, and the millions of people doing this work, deserve to have the scale of their contribution — and its cost to them — set down plainly and made easy to cite. We are not speaking over carers or claiming their cause as ours. We are amplifying it, and standing with the people who have been asking, reasonably, to be seen.

How to read this data

Carer numbers and health figures are from the 2021 Census (ONS); the value of unpaid care is a modelled estimate from Carers UK / the Centre for Care. Census question changes affect comparisons over time; confirm the latest figures before publishing. This is analysis of published data, not new research.
