UK 180-Day Visitor Stay & Frequent-Visit Border Risk Calculator

6 Months Per Visit vs. "Frequent or Successive Visits" (V 4.2b)

• ✓What the law actually says: Visa-exempt travelers (with a UK ETA) and Standard Visitor visa holders are granted up to 6 months per entry. There is no statutory rule stating "180 days maximum per 12 months."
• ✓How Home Office Caseworker Guidance applies it: Under Paragraph V 4.2(b), a visitor must not "live in the UK for extended periods through frequent or successive visits, or make the UK their main home."
• ✓The 180/365 rule of thumb: Border Force automated profiling flags travelers whose cumulative stay exceeds 180 days in any rolling 12 months—routing them from the e-Gates ("Seek Assistance") to an in-person officer interview.

Why a Quick Eurostar or Dublin Hop Often Backfires

• ✓The Common Travel Area (CTA) trap: Flying or taking the ferry to Dublin (Republic of Ireland) does not exit the Common Travel Area. Your original UK entry clock keeps ticking.
• ✓Short continental hops: Staying 5 months in London, taking the Eurostar to Paris for 3 days, and attempting to return for another 5 months is the classic pattern Border Force refuses or curtails to a 7-day "pack your bags" stamp.
• ✓Tax residency Danger at 183 days: Even if Border Force admits you, spending 183+ days in the UK during a UK tax year (April 6 – April 5)—or triggering the HMRC Statutory Residence Test (SRT) in as few as 90–120 days with UK ties—can make your worldwide income taxable in the UK.

Is there an official "180 days per year" law for UK visitors?

Strictly speaking, no—UK Immigration Rules Appendix V limits each individual visit to 6 months, not 6 months per year. However, Home Office Border Force guidance instructs officers to examine cumulative time spent in the UK over the past 12 months. Once you spend more than 6 out of 12 months in the UK, the burden shifts heavily onto you to prove you are not living in the UK via successive visits.

Why did the UK biometric e-Gate flash "Seek Assistance" when my passport normally works?

UK e-Gates cross-reference Advance Passenger Information (API) exit and entry logs in real time. If you have spent several months in the UK recently and re-enter after a brief trip abroad, the gate automatically refers you to a Border Force desk so an officer can verify your return ticket, finances, and residence abroad.

Does a trip to Dublin (Ireland) reset my 6-month UK visitor clock?

No. The United Kingdom, the Republic of Ireland, the Channel Islands, and the Isle of Man form the Common Travel Area (CTA). Traveling from London to Dublin does not terminate or reset your UK visitor leave; you must depart the CTA altogether.

Can I work remotely for my US or EU job while visiting the UK for up to 6 months?

Since January 31, 2024, updated Appendix Visitor rules explicitly permit visitors to work remotely on overseas employment activities (answering emails, joining calls, coding for a foreign employer), provided that remote work is incidental to a primary purpose of tourism or visiting family/friends—and not the primary reason you are living in the UK for 6 months.
