United Kingdom only requires your passport to remain valid for the length of your stay.
Airlines routinely deny boarding at check-in if your passport doesn't meet the destination's stated validity rule, even before you reach immigration — it's worth checking well before you book, not just before you fly.
No — passport validity and visa requirements are separate checks. Post-Brexit, the UK dropped the old EU-era 6-month rule — your passport just needs to cover your entire stay.
If your passport's expiry date is close to the cutoff this checker calculates, renew before booking — passport offices often take longer than travelers expect, especially in peak season.
