The UK government faces significant challenges in funding social care reforms, with a full National Care Service projected to cost around £17 billion annually by the mid-2030s. Current proposals, including changes to the state pension triple lock announced by Greater Manchester mayor Andy Burnham, are expected to generate only a small portion of the necessary funds in the early years of implementation.

One contentious funding option has been the introduction of a charge on estates—often referred to as a "death tax" by opponents—which has proven politically unpopular. Additionally, recent history shows few instances where British political parties have successfully campaigned on platforms to increase direct taxation ahead of general elections.

In response to these challenges, an analytics consultancy has proposed a model inspired by the workplace pension system's automatic enrolment scheme to fund social care more sustainably. The plan would require individuals aged 40 and above, including those past pension age, to be automatically enrolled in paying a social care premium. This premium would be funded by a 1 percent increase in the standard rate of income tax, amounting to just over £30 per month at maximum.

Contributors to the scheme would accrue discounts on their personal social care costs, with one year of payments granting a 4 percent reduction, two years 8 percent, and so forth, culminating in a full waiver of personal care expenses after 25 years. The policy’s opt-out feature, similar to the pension scheme, would allow flexibility, particularly for renters or those with limited assets who might already qualify for publicly funded care.

Estimates suggest that even with significant opt-outs, the policy could generate around £3.5 billion annually. Much of the scheme’s financial burden would fall in the future, as working-age contributors are unlikely to claim benefits until their elderly years.

Revenue from the premium could be strategically allocated to various areas. First, it could relax harsh asset thresholds for eligibility, currently set at £23,250 in England, by raising the limit to £100,000, thereby extending public funding eligibility. This change contrasts with higher thresholds and broader coverage seen in Scotland due to devolved powers over health and social care.

Second, funds could bolster preventive measures aimed at delaying the onset or worsening of conditions like dementia, which drive high care costs. Investments could also support informal caregivers, such as family and friends, thereby reducing the demand for state-funded care services.

Third, the collected revenues could accelerate the implementation of the envisaged National Care Service, a key priority for the prime minister's agenda.

Internationally, countries such as Japan and Germany have long operated mandatory long-term care insurance systems, with premiums collected for more than two decades and since the 1990s, respectively. The UK's proposed opt-out framework seeks a middle ground between mandatory contributions and political pragmatism, responding to the current system where individuals must save large sums independently to cover unpredictable, potentially catastrophic care costs.

Experts argue that a modest, state-facilitated social care premium would create a more equitable and manageable approach, spreading risk and providing protection that private markets have not traditionally offered. This proposal aims to balance fiscal responsibility, political acceptability, and improved social care accessibility.
