UK Travel 2025: Essential Entry Requirements, Safety Tips, and Health Advice for US Travelers

Travelers considering a trip to the United Kingdom should be aware of several updates and safety considerations as of April 2025. The U.S. Department of State advises exercising increased caution due to the ongoing threat of terrorism in the country. Authorities report that terrorist groups continue to plot potential attacks, which could target highly frequented locations such as tourist destinations, transportation hubs, markets, public gatherings, places of worship, and other busy public areas. In Northern Ireland, there is also a risk of isolated violence from dissident groups, primarily targeting police and military personnel. Travelers are encouraged to remain vigilant in public spaces and be prepared for possible disruptions.

Additionally, a new travel measure has been instituted for U.S. citizens entering the UK. As of January 2025, travelers from non-European Union countries, including the United States, are required to obtain an Electronic Travel Authorization (ETA) before entering or transiting through the UK. This electronic approval, linked to travelers’ passports, is valid for two years and allows stays of up to six months for purposes such as tourism, study, or visiting family. Applications for ETAs can be completed online or through a mobile app, requiring a fee, passport details, and a photo. Beginning April 9, 2025, the cost of an ETA is £16 per application.

Health and safety tips are also emphasized for travel in the UK. The Centers for Disease Control and Prevention (CDC) recommends vaccinations, particularly for those over 60 years old, against illnesses such as Hepatitis B. Road safety is another priority, as the UK drives on the left-hand side of the road—different from the U.S.—and traffic laws should be carefully reviewed before driving. Public transportation is widely available and considered a safe alternative for getting around.

Travelers should also plan appropriately for healthcare needs; though medical care in the UK is widely available, services in rural areas may involve longer wait times. Emergency services can be reached by dialing 999, and travelers are encouraged to have comprehensive travel insurance to cover any potential health-related costs during their stay.

Being proactive and planning ahead can ensure a safer and smoother travel experience when visiting the United Kingdom.
