UK Net Migration 2025: 171,000 + Trend (ONS Provisional)

The detail

UK net migration in the year ending December 2025 stood at 171,000 per ONS provisional estimates - approximately one third of the YE December 2024 figure (revised to 331,000) and around one fifth of the revised peak 944,000 in YE March 2023. The trajectory reflects deliberate tightening of work + study visa routes from January 2024 onwards (Skilled Worker minimum salary thresholds raised + dependant visa restrictions tightened), now fully working through the rolling 12-month measure.

The composition matters for the tax base. Non-EU+ nationals contributed positive 383,000 in YE June 2025; EU+ nationals negative 70,000; British nationals negative 109,000 (continued net emigration of UK-born citizens). Work-route migration is the most fiscally productive (immediate Income Tax + NI contribution); study-route migration is fiscally cost-positive in the short term (university fees + living spend) but neutral long-term unless graduates transition to work routes.

For population + Council Tax planning, net migration determines the labour-force trajectory. ONS population projections (2022-based, principal variant) assumed 245,000 net migration as long-term steady-state; actual 2025 outturn is now running below that assumption, with implications for State Pension funding, NHS workforce + housing demand on a 15-25 year horizon.

The November 2025 ONS methods update added more administrative-data sources to the long-term migration estimate. Provisional estimates are typically revised by ~50,000-100,000 over the following 12-18 months as more complete data becomes available. The YE December 2024 figure was revised down from initial 728,000 estimate to final 331,000 - a notable downward adjustment.
