The table is the UK area for 1991–2020 from the Met Office page that also prints Heathrow. The Met Office says the UK, regional, and district values are HadUK-Grid, not one station. London, Edinburgh, and Manchester have their own sheets, and they do not match this national line.

The Highway Code rule cited for driving is the Great Britain code. Northern Ireland publishes its own. The three city sheets are in England and Scotland, where this rule applies. VisitBritain's tipping notes are national and are repeated on the city sheets.

Driving side

Tap water

CDC's traveler page for the United Kingdom, last reviewed 25 August 2026, does not say whether tap water is safe or unsafe. It says food and water standards vary by destination and by what you are doing, and it points readers to CDC's food and water precautions. This page does not turn that into medical advice.

Currency

ISO 4217 lists the currency name Pound Sterling and the code GBP for United Kingdom.

Tipping

VisitBritain says tipping is not expected in Britain the way it is in some other countries, staff must be paid at least the National Minimum Wage, and a tip is polite for good service rather than required. Some bills add a service charge, which you can decline. If nothing is added, VisitBritain calls 10–15 a standard restaurant tip when the service was good, and 10–15 percent a nice gesture for a taxi, or rounding the fare up to the next pound. A hotel porter is customarily about £2.
