Long-term net migration to the UK nearly halved in 2025, falling to levels last seen before the post-Brexit immigration system, as tighter government measures restricted arrivals. The Office for National Statistics (ONS) reported the figure on Thursday.
Sharp Decline in Numbers
The ONS said net migration dropped to 171,000 in the 12 months to the end of December 2025, down from 331,000 a year earlier. This continues a steep decline from the record peak of 944,000 in 2023.
The current level is close to pre-2021 figures, before the new points-based immigration system was introduced following Britain’s exit from the European Union.
Policy Changes Driving the Drop
The reduction stems from policies introduced by the previous Conservative government and further tightened by the current Labour administration. Key measures include banning most international students from bringing dependants, raising salary thresholds for skilled worker visas, and ending overseas recruitment of care workers.
Interior Minister Shabana Mahmood stated that the government is “restoring order and control to our borders.” The Labour government has pledged even stricter measures to counter political pressure from Reform UK.
Immigration has remained a dominant political issue in Britain for over a decade. Successive governments have responded with higher salary requirements, reduced dependants, and faster deportations for illegal arrivals. Additional plans include extending the qualifying period for settled status and making refugee status temporary.
The British Future think tank noted that the country is experiencing one of the sharpest falls in net migration on record, though public perception often lags behind the actual data.
Analysts say the drop reflects both policy impact and changing global patterns. Work-related migration, particularly in the care sector, saw significant reduction. Student arrivals also declined due to dependant restrictions.
Despite the fall, debates continue over the economic effects of lower migration, including impacts on sectors facing labour shortages such as health and social care. Emigration trends, including British citizens leaving, also influenced the net figure.
The data is likely to feature prominently in ongoing political discussions ahead of future elections. Both major parties are under pressure to demonstrate control over immigration while addressing workforce needs.
