Britain’s net migration figures have taken a dramatic tumble. According to provisional data released by the Office for National Statistics, long-term international net migration to the UK fell to 171,000 in the year ending December 2025. That is nearly half the 331,000 recorded just a year earlier and the lowest figure since early 2021, when post-Brexit immigration rules were first introduced alongside pandemic-era travel restrictions.

The numbers tell a clear story. Fewer people are coming, and the government is taking full credit.

What Is Driving the Drop

The ONS says the single biggest factor behind the decline is a sharp fall in the number of non-EU nationals arriving for work. That category dropped by 47% compared to the previous year. Total long-term immigration to the UK stood at 813,000, down 20% from over one million the year before, and well below the staggering peak of 1.47 million recorded in March 2023.

Of those who did arrive, the majority were non-EU nationals, accounting for 627,000 of all arrivals. Study remained the top reason for coming to the UK, cited by 47% of non-EU migrants. Work accounted for 23%, asylum applicants made up 14%, with smaller numbers arriving through family and humanitarian routes.

Long-term emigration also fell slightly, from 680,000 to 642,000. The breakdown by nationality group reveals a striking picture. Net migration for British nationals remained negative at minus 136,000, meaning more Brits are leaving than arriving. EU nationals also showed a net outflow of minus 42,000. Non-EU nationals remained the only group in positive net migration territory, at 350,000, though that too was down sharply from 511,000 the year before.

Home Secretary Claims an 82% Drop in Three Years

Home Secretary Shabana Mahmood was quick to respond to the figures. In a statement, she said net migration had fallen by 82% in just three years. She added that while the government will always welcome those who contribute and wish to build a better life in the UK, restoring order and control to the borders remains a priority. She announced plans for a skills-based migration system designed to end Britain’s reliance on cheap overseas labour.

Work Visas and Asylum: The Bigger Picture

Separately, the Home Office published immigration statistics for the year ending March 2026, showing continued declines across the board.

Work visas across all categories fell to 252,775, down 17% on the previous year and 59% below the peak reached in late 2023. Skilled Worker visas were hit hardest, with only 110,725 granted. That is 76% below the December 2023 peak. The Home Office attributed the fall largely to a reduction in Health and Care visas following policy changes on overseas NHS recruitment.

Asylum claims came in at 93,525 for the year to March 2026, down 12% but still significantly above pre-2021 levels. Just over half of all claimants had entered through irregular routes, including small boats, while 39% had previously held a valid UK visa. The initial grant rate dropped to 39%, down from 49% the previous year.

The countries sending the most asylum seekers were Pakistan, Eritrea, Iran, Afghanistan, Bangladesh and Sudan, together making up 46% of all claims. Grant rates varied widely. Sudan and Eritrea recorded the highest approval rates at 93% and 87%, respectively. Bangladesh, Turkey and India recorded the lowest, with India at just 1%.

In arguably the most significant administrative development, the asylum backlog has been cut by 55%. At the end of March 2026, only 48,758 people were awaiting an initial decision, the lowest figure since September 2019.

The ONS cautioned that all figures remain provisional and will be revised as additional data becomes available.
