UK net migration fell to 171,000 in the year to December 2025, according to Office for National Statistics figures published Thursday — the lowest figure since 2012, excluding the Covid pandemic years, and roughly half the 2024 total. Total immigration to the UK exceeded 800,000, down around 20% year on year, while emigration reached 642,000. The decline was driven primarily by reduced non-EU arrivals for work, following a series of policy changes initiated under the Conservatives and extended by the Starmer government: the skilled worker salary threshold was raised from £26,200 to £38,700, overseas students were largely barred from bringing family members, and care workers lost the right to bring dependants. Asylum applications fell 12% year on year to 93,525, though backlogs in the appeals system rose 91% to 80,333 cases. The government has announced further tightening: a language requirement at near-A-level standard for migrants and a further salary threshold increase to £41,700.
The received wisdom
For the liberal-cosmopolitan wing of British commentary, the migration figures are a source of deep ambivalence. The argument runs: immigration controls that reduce economically productive inflows — skilled workers, international students, healthcare staff — in order to hit a headline number that plays well in marginal constituencies are not good governance; they are demographic vandalism driven by polling. Britain has an ageing population, a productivity deficit, and a public services crisis that depends substantially on migrant labour to function at all; artificially suppressing the numbers by pricing out exactly the workers the economy most needs is a form of self-harm dressed up as border management. The human costs are also real: families separated by income thresholds, students unable to bring spouses, care workers returning home because the rules have changed mid-career. On this reading, hitting 171,000 is less a triumph than a choice to trade economic dynamism for political reassurance — with the reassurance likely to be temporary.
A different read
The liberal critique has genuine force on the economic composition point — and the Oxford Migration Observatory’s Ben Brindle was quoted by the BBC saying exactly this: migration of groups making “positive or broadly neutral economic impacts” has fallen, while asylum-related migration remains high, making the compositional shift “less favourable from an economic perspective.” This is worth taking seriously. But the argument that policy controls on migration are inherently counterproductive has always struggled against the basic political reality that public tolerance for high immigration levels is finite, and that ignoring that finitude eventually produces outcomes far more damaging than sensible management would have done.
The Conservative period from 2016 to 2024 is instructive. The party held power for eight years while net migration rose from roughly 300,000 to a peak above 700,000 — with spikes driven substantially by the government’s own decisions to relax healthcare and care sector visas to address workforce shortages created, in part, by its own earlier policies. This was not an accident; it was a series of departmental decisions made in isolation from each other, without any coherent framework for managing aggregate inflows. The result was that voters who had been told for a decade that the government shared their concerns about migration levels were presented with evidence that those concerns had either not been heard or had been wilfully overridden. The electoral consequences arrived in the 2024 election and the subsequent Reform surge.
What Starmer’s government has done — whatever one thinks of the substance — is something the Conservatives demonstrably could not: it has produced an actual reduction in the headline figure, used the same policy levers that were available to its predecessor, and done so while managing the internal party tension between a Labour base that is uncomfortable with restrictionism and a electorate that has made clear it will punish parties that appear complacent. The Shadow Home Secretary’s response — that 246,000 British nationals leaving represents a “Starmer exodus” of entrepreneurs driven away by high taxes — is a legitimate argument but one that the ONS data somewhat undercuts, since British national emigration has been broadly stable across recent years, running at 255,000 in 2023 and 257,000 in 2024.
The harder question, and the one the numbers cannot resolve, is whether 171,000 is a stable equilibrium or a temporary dip that will reverse as the economy adjusts to labour scarcities created by the restrictions. The appeals backlog — up 91% to over 80,000 — is a structural vulnerability. Ninety percent of detected illegal arrivals came by small boat; the small boat problem has not been solved, and the political pressure it generates is unlikely to abate. The government’s 2029 target for ending hotel accommodation for asylum seekers is ambitious given that there are still nearly 21,000 people in hotels and the legal pipeline is lengthening rather than shortening.
What to watch
- Whether the compositional shift — fewer skilled workers, proportionally more asylum seekers — feeds through into public services and labour market data in ways that reset the political debate by 2027.
- Reform UK’s response: if the headline number falls further toward or below 100,000 — the Conservatives’ repeatedly broken promise — it removes one of Reform’s most effective grievances. The question is whether the party pivots to enforcement and composition rather than headline volume.
- The skills-based migration framework the government has promised: the test is whether it can articulate a positive argument for the workers Britain needs while maintaining credibility on control — a political combination no party has successfully sustained.
- The appeals backlog growth rate: a 91% increase in one year is unsustainable, and if it drives an increase in successful appeals and subsequent grant of leave, it will complicate the government’s claims to have restored “order and control.”
