Every year, hundreds of thousands of people visit the United Kingdom on temporary visas — tourist visas, student visas, skilled worker visas, and visitor entry clearances. The vast majority leave on time. But sometimes circumstances intervene: a medical emergency, a change in personal situation, or simply losing track of the deadline. When your visa expires and you remain in the UK, you become an overstayer from that day — with no grace period and immediate legal consequences.
There Is No Grace Period in the UK
Unlike some other countries, the UK does not automatically give you extra days after your visa expires. Day one after your visa end date is day one of overstaying. Two narrow rules can help. If you apply for new permission within 14 days of your old permission ending and can show a good reason beyond your control, such as a medical emergency, the Home Office may disregard the overstay. And if you leave voluntarily, at your own expense, within 30 days, no re-entry ban applies. Neither is a standard allowance.
If you applied to extend your visa before it expired, you may be protected by Section 3C leave, which keeps you lawfully in the UK while your application is pending. If you did not apply before your visa expired, no such protection exists.
The Consequences of Overstaying
Knowingly overstaying can be a criminal offence under Section 24 of the Immigration Act 1971. In practice, prosecutions for straightforward overstaying are uncommon — but the overstay is permanently recorded. Future UK visa applications, and visa applications for many other countries including the US, Canada, Australia, and Schengen nations, require you to declare any previous immigration violations. A UK overstay is treated as a serious negative factor by immigration authorities worldwide.
When you leave the UK, whether a re-entry ban applies depends on how long you overstayed and how you leave. Leaving voluntarily at your own expense within 30 days means no ban. After that, a 12-month ban on applications usually applies. Leaving at the Home Office's expense can mean 2 or 5 years, and removal, deportation or deception can mean 10 years.
What This Calculator Does
This tool takes your UK visa expiry date and calculates exactly where you stand today. It tells you whether the 14-day exception window is still open, how long you have overstayed, what re-entry consequences apply, and what your immediate options are. The calculator is based on the Immigration Rules and published Home Office guidance. Rules change, so always check the current wording.
This is a free informational tool — no data is stored, no registration required. If your situation is complex, especially if you have a pending application, a criminal record, or family ties in the UK, you should speak to a qualified UK immigration solicitor before taking any action.
