UK net migration in the year ending June 2025 was approximately 204,000, per provisional estimates published by the ONS on 27 November 2025. This figure marks a 68.6 per cent year-on-year decrease and a 78 per cent drop from the 2023 peak. The shift coincides directly with the Labour government taking office in July 2024 and subsequent policy reforms.
What was the Boriswave in UK net migration?
The post-Brexit surge in UK net migration, colloquially known as the Boriswave, began to peak in 2022. Net migration stood at approximately 745,000 in the year ending June 2022. It then reached its highest recorded level in modern UK statistical history at approximately 906,000 in the year ending June 2023. This surge occurred under the points-based immigration system designed by Boris Johnson's Conservative government, which took effect from 1 January 2021.
During its 2010 to 2024 tenure, the Conservative government maintained a stated target of reducing net migration to the 'tens of thousands'. This target remained unmet throughout their time in office. For context, pre-Brexit average annual net migration ran at approximately 270,000 in the years leading up to the 2019 general election. The 204,000 figure for the year ending June 2025 now falls below that pre-Brexit baseline.
How did Labour's policy changes affect net migration?
Sir Keir Starmer's Labour government took office on 5 July 2024 following the general election. In May 2025, the Labour government published an Immigration White Paper outlining eight key policy changes to the UK immigration system. Prime Minister Sir Keir Starmer publicly stated in May 2025 his desire to reduce net migration 'significantly' by the end of the current parliament, without committing to a specific numerical target.
Among the announced policy changes were the closure of the overseas care worker visa route to new applicants from July 2025, and a raising of the Skilled Worker visa skills threshold to degree level. Stricter English language requirements across multiple visa routes and a reduction in the occupations eligible for Skilled Worker visa sponsorship were also implemented. The Labour government's own published assessment estimates these White Paper changes could reduce immigration to the UK by approximately 100,000 additional per year, on top of trends already in motion.
Which migrant routes saw the biggest declines?
ONS analysis indicates that the observed fall in net migration is primarily driven by fewer non-EU+ nationals arriving for work and study reasons. This is combined with a continued gradual rise in emigration. A notable impact is seen in dependant routes. The number of work and study dependant arrivals fell dramatically from a 2023 peak of approximately 374,000 to approximately 98,000 in the year ending June 2025. A 73.8 per cent drop.
Does the new data challenge Reform UK's immigration stance?
Reform UK's 2024 general election manifesto and continuing campaign messaging place the reduction of immigration as a central political priority. However, the ONS data reveals a critical shift. The post-Brexit migration surge that Reform UK critiques was engineered by a Conservative government. The substantial reforms bringing down net migration have been enacted by a Labour government. For further analysis on related political claims, consider Reform UK's tax cut math, the diversity data gap in Reform UK's councillor base, and the challenges Reform UK faces regarding the triple lock. The scale of the migration decrease also impacts potential future Labour leadership discussions.
What this means for UK households
The drastic reduction in net migration to 204,000 in the year ending June 2025 marks a significant shift in UK demographics and policy outcomes. Households will see the long-term effects of fewer new arrivals, particularly in sectors previously reliant on overseas workers and students. The impact on public services, housing demand, and economic growth will become clearer as these trends embed.
