A healthcare support worker who joined an NHS trust from overseas under the immigration rules then in force would have been counting towards a settlement date five years away. Under the government's earned-settlement proposals, that date could move to fifteen years for anyone in a role below degree level, and the sponsoring trust would carry the cost of every additional year on a visa. Employers and unions put the bill for NHS organisations at no less than £169 million and say it affects around 12,000 staff.

 The Social Partnership Forum, on which the Department of Health and Social Care sits, has joined NHS Employers in raising concerns. The figure deserves scrutiny, since its components are not fully itemised, but it understates the exposure in one respect that matters more than the arithmetic. It counts sponsorship and employment costs. It does not count the colleague who decides that fifteen years is too long to wait and leaves for work that offers a quicker route to security. Each departure also sends a trust back to recruitment and induction, with the overhead that implies. 

Healthcare support workers take on observations and routine clinical tasks that would otherwise fall to registered staff, and domestic recruitment and training cannot replace them at the speed a rule change can remove them. A colleague in a degree-level role on the same ward could be eligible to settle years earlier, which creates a morale problem on top of a fairness one.

 The Home Secretary has defended the reforms by pointing to the historically large numbers who arrived after 2021, and a government entitled to set migration policy is entitled to change it for future arrivals. The dispute concerns people already here. The consultation closed in February with more than 200,000 responses, the Home Secretary has said the changes will apply retrospectively, and a decision is promised very soon. At party conference she acknowledged that some regard elements of the reforms as unfair, which has been read as a signal that she may soften them. 

The reading is plausible but unconfirmed, and trusts cannot plan workforce budgets around a signal. The structural problem is one of accounting. A settlement rule is a Home Office decision whose costs fall on trust budgets and, through them, on the waiting lists a government has staked its health agenda on reducing. No ledger records that transfer. Trusts already operating under tight financial controls would meet it from the same pool that funds wards and theatre lists, and the Home Office would never see the invoice. 

A policy aim of reducing reliance on overseas recruitment is reasonable, but it is met through training pipelines over years, and the people affected by this rule are already in post. NHS Employers has not asked for the reforms to be abandoned. Its consultation response accepts a ten-year baseline for all health and care workers and asks that staff already on a pathway to settlement are not disadvantaged. That is a position a government could accept without conceding its principle.

 Two things would make any concession credible. Existing staff need written transitional protection, so that those who arrived under the five-year rule are judged by it. And the Home Office and the Department of Health and Social Care need to publish a joint assessment of what the change costs the health service, so that the next decision is taken with the NHS invoice visible. 

For NHS leaders the practical task is to establish now how many of their sponsored support staff would be affected and when, because the answer determines retention planning. 

For the government the question is whether a settlement date is a commitment or a variable. If it is a variable, every international recruit and every trust that sponsors one has learned that terms agreed at the point of arrival carry no weight, and the NHS will discover the consequences in its vacancy figures long before the Home Office does.
