Labour’s leadership is facing internal divisions over proposed reforms to immigration rules introduced under the previous government, raising concerns about the long-term fiscal impact of allowing a substantial number of low-income migrants to gain indefinite leave to remain (ILR) in the United Kingdom.
The controversy centers on changes proposed last year by Shabana Mahmood, the home secretary, intended to tighten the criteria for migrants to settle permanently in the country. These reforms would have replaced the existing system—where migrants qualifying after five years could apply for ILR—with a graduated approach factoring in economic contribution, integration, and conduct. Under the plan, high earners could qualify for settlement more quickly, while low earners might face longer qualifying periods, potentially up to 15 years. Additionally, the proposals suggested restricting access to benefits for new ILR holders, reserving such support primarily for citizens.
The urgency for reform stems from a surge in migration during the administration of former Prime Minister Boris Johnson, dubbed the “Boriswave.” Between January 2021 and June 2024, nearly four million people were granted long-term visas, overwhelmingly from outside the European Union. The majority arrived under lowered skill, salary, and English language thresholds, leading to an influx of low-wage workers, students, and dependants. Care workers were a notable group, with thousands arriving and bringing multiple dependants, contributing to increasing demands on public services and welfare.
Economic analyses indicate that the average low-wage migrant who arrives at age 25 could cost the taxpayer upwards of £125,000 by state pension age, with lifetime costs potentially reaching £500,000. Granting ILR to these individuals grants entitlement to full welfare benefits and social housing, increasing potential fiscal burdens over coming decades.
Mahmood—addressing these concerns soon after assuming her role—proposed reforms aimed at ensuring ILR would be contingent upon demonstrable economic and social contributions. However, the approach has met opposition from the left wing of the Labour Party, including figures such as Angela Rayner and Andy Burnham, who have argued that applying new rules retroactively to migrants already in the country would be unjust. Some Labour MPs have called for exemptions for care workers, despite warnings about the high costs associated with this group.
Mahmood’s position appears increasingly constrained amid internal party dissent and a lack of overt support from Downing Street. With no consensus reached, many migrants from the Boriswave cohort have already begun qualifying for settlement since January 2026, at a rate of nearly 5,000 per week. The influx of care workers eligible for ILR is anticipated to accelerate next year.
Critics of Labour’s current stance argue that the initial surge in migration occurred without sufficient public consultation and that permitting widespread permanent settlement of low-wage migrants threatens to strain the UK’s economic and social infrastructure. Conversely, Labour figures opposing the reforms emphasize fairness and caution against punitive measures that could undermine migrant communities.
As Labour grapples with balancing humanitarian considerations, party unity, and fiscal responsibility, the ongoing debate over immigration policy highlights broader tensions over migration’s role in Britain’s future economic and social landscape.
