The United Kingdom faces considerable fiscal uncertainty as significant cuts to net migration come into effect. The Office for Budget Responsibility (OBR) is expected to make a pivotal decision when forecasting for the 2026 budget, with recent government measures suggesting annual net migration could fall from previous highs of nearly one million to around 100,000.
These changes, driven by tightening visa policies and ongoing political competition, have substantial financial implications. Experts warn that lower net migration could reduce government revenues by up to £14 billion, forcing difficult decisions over tax policy and spending.
UK Net Migration Trends
Between 2019 and 2023, net migration to the UK rose sharply, peaking near one million annually. This surge was partly attributed to humanitarian visa schemes for Ukrainian and Hong Kong nationals, as well as the government's liberalisation of visa policies following Brexit.
These changes were intended to compensate for labour shortages resulting from the end of free movement with the European Union. By late 2023, however, the Conservative government reversed several of these measures, contributing to a notable decline in net migration even before Labour took office.
Policy Changes and Political Pressures
Upon assuming power, Prime Minister Keir Starmer's government faced growing political pressure from the rise of the Reform party. In response, Labour implemented additional restrictions in May, including the abolition of social care visas, stricter English language requirements, and tougher post-study work rules for graduates.
Further reforms, scheduled for later in the year, are set to tighten eligibility for indefinite leave to remain and citizenship. According to official data, visa applications in skilled and health worker categories have since dropped precipitously, with health worker visa applications declining from a peak of 18,300 in August 2023 to just 900 last month.
Fiscal Implications of Reduced Migration
The OBR’s last forecast assumed annual net migration of 300,000. However, emerging trends suggest figures closer to, or even below, 100,000. A permanent shift to lower net migration would leave a £14 billion hole in government tax revenue, eroding more than two-thirds of the current fiscal headroom.
The government faces the possibility of increased taxes or additional spending cuts. Immigrants are typically younger and economically active, contributing more in taxes than they consume in public services, which amplifies the fiscal impact of reduced migration.
Impact on Labour Market and Public Services
The reduction in net migration presents significant challenges for the domestic labour market and public services. Many sectors, including social care and construction, have experienced rising vacancies despite efforts to promote training and recruitment of UK-born workers.
Experts note that while some visa routes were being exploited, ending them without accompanying measures risks exacerbating labour shortages and inflating wages, potentially fueling further inflation.
For example, despite an increase in social care wages alongside new restrictions, the number of British workers entering the sector has fallen.
Business Response and Workforce Challenges
While policymakers hope businesses will compensate for workforce gaps by investing in training and reducing youth unemployment, studies indicate limited success. Many jobseekers face barriers unsuited to critical sectors reliant on migrant labour.
Businesses also face steep costs as UK visa fees now exceed those in many competitor countries. It is estimated that a skilled worker with a family may pay over £42,000 in visa and settlement fees before citizenship, in addition to regular taxation.
Final Summary
The sharp fall in net migration following policy reforms has introduced significant fiscal and economic challenges for the United Kingdom. The loss of younger, working-age immigrants is projected to subtract billions from government revenues and may lead to further tax rises or spending cuts.
Critical sectors such as social care and construction are likely to be affected by labour shortages, as attempts to boost domestic recruitment have yielded limited results. Long-term analysis suggests that skilled migration delivers clear fiscal benefits, but political imperatives continue to shape policy choices.
