Travelers planning to visit London should be aware of significant changes to the UK’s entry requirements coming in early 2025. Starting January 8, 2025, all visa-exempt nationals, including US citizens and Spanish passport holders, will need to obtain an Electronic Travel Authorization (ETA) before entering the United Kingdom. This new requirement applies to tourists, business travelers, and those visiting for short studies up to six months.
The ETA system is entirely online and costs between £10 and £16. Once approved, it remains valid for two years or until the passport expires, whichever comes first. Processing typically takes up to three working days, so travelers should apply well in advance of their journey. Children of all ages, including infants require ETAs, as each traveler must have their own authorization document. The application doesn’t require specific travel details, making it flexible for multiple entries during its validity period. Additionally, families traveling with young children can benefit from accessible public transport options that accommodate strollers and provide priority seating.
Apply for the UK’s ETA online at least three days before travel. Pay £10-£16 for a two-year multi-entry authorization.
Certain travelers are exempt from the ETA requirement. These include those holding a UK visa, British or Irish passport holders, and legal UK residents. However, the ETA is not a substitute for a visa, which remains necessary for work or long-term stays exceeding six months.
Beyond the new ETA system, travelers to London should prepare several essential documents. These include a valid passport that remains current throughout the stay, proof of return or onward travel, and accommodation confirmation such as hotel bookings or invitation letters. Visitors can now travel with peace of mind as all COVID travel restrictions have been lifted in the UK since March 2022.
International health insurance is strongly recommended, and having proof of sufficient funds is advisable, though rarely requested at border control.
Looking ahead, Europe is implementing additional border systems. The Entry/Exit System launches in October 2025, followed by the European Travel Information and Authorization System in late 2026. These systems will enhance security through biometric registration for non-EU visitors.
For tourists planning their London experience, allow multiple days to explore major attractions like Westminster and Soho. Central areas tend to have higher prices and more tourists, while neighborhoods like Notting Hill and Shoreditch offer more authentic local experiences.
Guided tours can provide skip-the-line access and reveal hidden spots that might otherwise be missed.
