📝 Travel notes
Tipping
Tipping is appreciated but less automatic than in the United States. Restaurants may add a service charge; if not, 10-12.5% is common for good table service. Tipping in pubs is not usually expected.
Best season
Late spring through early autumn offers the longest daylight and the best chance of mild weather. May, June and September are especially good for city breaks because they avoid the busiest school-holiday weeks.
Visa basics
Visa requirements depend on nationality, length of stay and purpose of travel. Some visitors can enter visa-free for short tourism trips, while others need a Standard Visitor visa or an Electronic Travel Authorisation. Confirm through the official UK government visa checker.
