For years, a quick weekend trip to London for Spanish travelers meant little more than packing a bag and crossing the English Channel. The ease of travel, relying on a simple DNI (national identity document), felt akin to moving between neighboring regions. That simplicity is now a memory. As of 2026, visiting London requires a new level of planning and documentation, reflecting the lasting impact of Brexit on travel between the UK and its European neighbors. Understanding these changes is crucial for anyone planning a trip to the British capital and failing to do so could mean being denied boarding or entry.
The most significant shift is the introduction of the Electronic Travel Authorisation (ETA), a mandatory digital permit for visitors from Spain and many other countries. This requirement, which came into effect in 2024, effectively acts as a “digital green light” for entry, mirroring systems already in place for countries like the United States. Without a valid ETA, travelers will be unable to board flights or trains destined for the UK. The application process is online and generally straightforward, but adds an extra step – and a cost of £16 (approximately €19-20 as of March 2026) – to the pre-travel checklist. The ETA is valid for multiple entries over a two-year period, according to the UK government website. Apply for an ETA here.
The require for an ETA underscores a fundamental change in the relationship between the UK and the European Union. While the UK remains a popular tourist destination, the post-Brexit landscape necessitates a pre-screening process that didn’t exist before. This isn’t about closing borders, but about implementing a new layer of security and control. It’s a shift from the frictionless travel enjoyed for decades to a system that demands proactive preparation.
The Passport Requirement: A Tangible Change
Beyond the digital ETA, a more concrete change has taken effect: the DNI is no longer sufficient for entry into the UK. Regardless of the length of stay, a valid passport is now mandatory for all Spanish citizens. This requirement, while seemingly minor, has caught many travelers off guard, particularly those accustomed to traveling within Europe with only their national ID card. The UK government confirmed this change in travel guidelines following the full implementation of Brexit protocols. Check the latest UK visa requirements.
Despite these new hurdles, Spanish citizens can still enter the UK as tourists without a visa for stays of up to six months. Though, the process is undeniably more complex. The spontaneity of a last-minute trip has diminished, replaced by a need for careful planning and adherence to new regulations. This transformation, while subtle, is a clear indication of the post-Brexit reality.
Increased Scrutiny at Border Control
Upon arrival in the UK, travelers should anticipate more thorough border control checks. While most visitors experience a smooth process, it’s increasingly common to be asked to justify the purpose of your trip, provide proof of accommodation, or explain your itinerary. Having an approved ETA doesn’t guarantee automatic entry; the final decision rests with the immigration officer. Travelers should be prepared to answer questions and provide supporting documentation.
Even seemingly minor details have been affected. Travelers transiting through the UK – even for a short layover – may also be required to obtain an ETA. This is a frequently overlooked requirement that can cause significant disruption. The rules surrounding mobile phone roaming and healthcare coverage have changed.
Healthcare and Connectivity Considerations
The European Health Insurance Card (EHIC) remains valid in the UK, but its level of coverage has been reduced compared to the pre-Brexit era. This means that travelers may be responsible for a larger portion of their medical expenses. Purchasing comprehensive travel insurance is now highly recommended.
Similarly, mobile phone roaming charges may apply, and it’s advisable to check with your mobile provider before traveling. The automatic, seamless connectivity previously enjoyed within the EU is no longer guaranteed.
Despite these changes, London remains a hugely popular destination. The city continues to attract millions of visitors each year, drawn by its history, culture, and vibrant atmosphere. However, the journey to the British capital has evolved. It’s no longer the simple, spontaneous trip it once was, but rather a carefully planned experience that requires a bit more preparation. The capital has transitioned from a nearby, almost domestic destination to one that demands a preliminary ritual, a constant reminder that Brexit wasn’t just a political shift, but a tangible transformation in the traveler’s experience.
The changes to travel requirements between Spain and the UK are a direct consequence of the UK’s departure from the European Union. While London remains accessible to tourists, the process now involves more administrative steps and increased scrutiny. Staying informed about these evolving regulations is essential for a smooth and stress-free trip.
The UK government is expected to review the ETA scheme in late 2026, potentially introducing further adjustments based on its initial implementation. Travelers should continue to monitor official government websites for the most up-to-date information.
