Small boat arrivals · 2018–2026 ~204,271

Total people detected crossing the English Channel in small boats since 2018. Past years come from the Home Office irregular migration dataset. The 2026 figure is approximate (shown with a ~ prefix) because the year is still in progress. It's the running count from the small boat arrivals weekly data, up to Thu, 25 Jun 2026.

Total asylum system cost · 2010/11–2024/25 £23.5bn

Total spent on the asylum system between 2010/11 and 2024/25, summing the Home Office's published annual asylum cost figure (ASY_04). This is a single combined figure covering both processing (casework and decision-making) and support (asylum accommodation and subsistence) — the Home Office does not publish the two split out separately. See the asylum support page for the yearly breakdown and the cost per decision.

2025/26 and 2026/27 are not yet shown — the Home Office publishes ASY_04 by completed financial year (April–March) with a 6–12 month lag, so the 2025/26 figure typically won't appear until late 2026 or early 2027.

Data analysis #

Disclaimer #

Migrant Data UK brings together official UK Government statistics on immigration, asylum, and small boat crossings in one place. Every chart and table on this site is built directly from data published by the Home Office, including the Immigration System Statistics and the Migration Transparency Data collection. The data covers small boat arrivals across the English Channel, irregular migration trends, asylum claims and initial decisions, grants of protection, asylum seeker support and accommodation, processing costs, and the asylum decision backlog. All figures are updated automatically when new data is released, so the numbers you see here always reflect the latest available quarter or financial year. The site is designed to make it easier to understand how these figures have changed over time and how they compare across different categories.

About the data #

All data on this site is sourced from the UK Home Office and published under the Open Government Licence v3.0. Each page shows the exact source file, sheet name, and last sync date so every figure can be traced back to the original publication.
