Evidence Note 02: Technical Analysis and Workforce Impact Assessment of Proposed Retrospective Settlement Reforms
Technical analysis and workforce impact assessment of proposed retrospective settlement reform under CP1448, with attention to attrition, employer sunk costs, fiscal contribution and family integration.
Summary
Whether retrospective settlement reform could affect workforce stability, employer planning, fiscal contribution and medium-term retention among existing Skilled Worker cohorts.
The note draws on employer survey material, nursing and care-sector retention evidence, fiscal modelling, sponsorship and training-cost estimates, and housing and family-integration evidence.
It records a potentially affected settlement-route population of around 1.35 million, links prolonged status insecurity to attrition and sponsor dependency, and identifies employer sunk costs and household pressures created by longer provisional status.
The implication is that settlement reform should be assessed as policy risk reallocation across workers, sponsors, public-service labour markets and families already relying on published route expectations.
Key Proposition
Retrospective settlement-period extensions should be assessed as a workforce, fiscal and employer-investment risk, because they can prolong status insecurity for people and sectors already relying on the published five-year settlement framework.
Key Observations
- The source note estimates that around 1.35 million people already on routes to settlement could face default longer qualifying periods, with worker-route applicants and dependants forming the majority of the affected group.
- Retention evidence is treated as central: the note records that 60% of migrant nursing staff without permanent status said doubling the residence requirement to ten years would likely affect their decision to remain in the UK.
- Employer evidence is used to show recruitment and retention risk: a December 2025 Migrate UK survey of 95 employers found 79% expected a ten-year settlement route to make overseas recruitment harder, 92% expected lower retention, and 85% viewed the existing five-year route as a critical attraction factor.
- The note connects route insecurity to sponsor dependency, reduced worker mobility and exploitation risk, including evidence that only 42% of sampled care workers attempting to switch sponsors succeeded and 5% found another sponsor within the 60-day window.
- Fiscal and employer-cost evidence is presented together: the note records positive lifetime fiscal contribution estimates and identifies employer sunk costs that may reach approximately £20,020 in health and social care and £24,640 in education by a seven-year sponsorship point.
- Family integration and housing access are treated as workforce-relevant factors because prolonged temporary status affects whether workers and households can remain, plan and invest locally.
