No visa, up to 180 days
No. US citizens can stay in the United Kingdom for up to 180 days per visit without a visa.Entry: 6 months per visit (no statutory annual window).
How the days are counted
The limit applies to each visit. Leaving and coming straight back does not guarantee a fresh allowance, and a pattern of back-to-back stays can be refused at the border.
Staying longer than a holiday?
Visa days are one count. Long stays can also start a tax residency clock. See how Residency tracks tax residency.
Entry rules change, and border officers have the final say. Confirm with the United Kingdom's official immigration site before you travel.
