Stopover in London: what to do and when to leave
Heathrow combines large terminals, border controls and a journey to the center that can exceed an hour door to door. A long layover doesn't always mean that visiting London is wise.
With less than 8 hours, stay at Heathrow. From 9–10 hours Paddington or Westminster may be viable if entry to the UK is confirmed and you do not have to check-in again.
Your safety comes first. Reviewed on August 13, 2026 · Guidance, not immigration authorization.

Frequently asked questions
Before deciding
Do I need an ETA for a stopover in London?
It depends on your nationality and whether you pass border control. Check the official requirement for your specific route before traveling.
Can I leave Heathrow during a layover?
Yes, if you have entry authorization and a wide margin. For central London we recommend considering departures only on stopovers of around 9 hours or more.
What to do on a long layover at Heathrow?
With enough margin, choose Paddington or Westminster. With less time, a lounge, hotel or walk through the terminal greatly reduces the risk.
