UK net migration has fallen by almost half in a dramatic shift driven by a steep decline in non-EU arrivals and changes to work and study visas, according to official figures.
New estimates from the Office for National Statistics show net migration stood at 171,000 in the 12 months to December 2025, down 48 per cent on the previous year and the lowest level since early 2021.
The figure continues a broader downward trend from the post-pandemic peak, when net migration reached 944,000 in the year to March 2023 before beginning a sustained fall.
Net migration measures the difference between those arriving in the UK to live long-term and those leaving the country.
The latest data show the decline has been driven primarily by fewer arrivals from outside the EU to work, study or join family members, alongside an increase in emigration, particularly among former international students.
The figures break down into three main components: 350,000 more non-EU nationals arriving than leaving; 136,000 more British citizens leaving the UK than returning; and 42,000 more EU citizens leaving than arriving over the same period.
The ONS said the reduction reflects both policy changes introduced under the previous Conservative government and further tightening under Labour.
Measures include restrictions on international students bringing dependants, limits on care worker family visas, and higher salary thresholds for skilled worker and family routes.
In 2025, the Labour Government introduced additional reforms, including ending overseas recruitment for care workers and further raising income requirements for skilled visas.
The Home Office has reported a sharp fall in visa applications since these changes came into effect, with declines continuing into 2026.
Alongside the migration figures, the data also show a fall in the number of asylum seekers housed in hotels, down to 20,885 at the end of March 2026 — a 35 per cent reduction year-on-year.
Shabana Mahmood said the figures demonstrated “real progress” in reducing net migration but warned that further reform was still required.
“Net migration has fallen by 82 per cent in just three years,” she said. “We must restore order and control to our borders.”
She added that the Government was moving towards a “skills-based migration system” designed to prioritise higher-skilled workers and reduce reliance on lower-paid overseas labour.
Shadow home secretary Chris Philp said the figures masked deeper problems, including large numbers of Britons leaving the country and continued pressure from low-skilled migration.
He called for a binding annual immigration cap and tighter restrictions on settlement rights, arguing that Labour lacked the political resolve to go further.
Think tank commentary suggested the sharp fall in migration should prompt a more “measured debate”, warning against policy responses driven by older pressures rather than current trends.
Despite the decline, analysts cautioned that migration remains a politically sensitive issue, with continued pressure on housing, public services and labour markets shaping debate across Westminster.
The latest figures mark a significant reversal from recent years of record-high inflows, but also signal a more volatile and politically contested phase in UK immigration policy.
