Get Ready for New Travel Regulations in 2026 – UK Tourists Must Adapt to EU Border, Passport Rules

Travel in 2026 is set to look very different for UK holidaymakers. As more than half of Brits plan to travel abroad in the coming year, significant changes to border entry systems, passport rules, and travel authorisations will impact how they experience international travel. While some of these new systems aim to streamline entry processes, experts warn they could lead to longer waits and confusion, especially for those who aren’t aware of the upcoming rules.
Holidaymakers heading to Europe, the United States, and other popular destinations should take note of these changes well before they book their trips. For many, the advent of biometric checks and the new ETIAS travel authorisation system will require careful planning to avoid disruptions at the border.
New Biometric EU Border Checks (EES)
The EU’s Entry/Exit System (EES), which came into effect last October, replaces traditional passport stamping with biometric checks like fingerprints and facial recognition for non-EU travelers, including UK citizens. These new procedures are designed to speed up border processing times, but there have been reports of delays as the system continues to roll out across airports and ports.
Experts, including Nicole Kerr, CEO of Mozio, warn that the initial implementation may cause frustration as holidaymakers adjust to the new systems. While the EU biometric checks are expected to reduce wait times over time, they will require extra time for processing, and travelers should arrive earlier at airports, ports, or train stations to ensure smooth entry.
Key Tip for Tourists:
- Allow extra time at airports, ports, and Eurostar terminals for these new checks, as the transition to biometric systems may cause initial delays.
ETIAS Launching in 2026: A New Travel Authorisation System
A game-changer for UK travelers, the European Travel Information and Authorisation System (ETIAS) will officially launch in late 2026. UK passport holders traveling to 30 European countries in the Schengen area for up to 90 days will need to apply for an online authorisation before departure.
Unlike a visa, the ETIAS will require travelers to fill out an online form and pay a €20 fee, which will be valid for three years or until the passport expires. This system aims to increase security and streamline entry into Europe, but holidaymakers need to be aware that boarding without ETIAS approval will be impossible.
Key Tip for Tourists:
- Apply for your ETIAS authorisation well in advance of travel, and avoid unofficial websites that may attempt to charge for early approvals.
New Passport Rules for Dual Nationals in 2026
Changes to UK travel rules also affect dual nationals, particularly those holding both British and Irish passports. Starting this year, dual nationals must ensure they travel to the UK using either a UK or Irish passport. If they wish to use another passport, they must carry a certificate of entitlement proving their right to reside in the UK.
For travelers with dual citizenship, it’s essential to confirm the correct passport for travel well in advance, as entering the UK with the wrong passport could result in denied boarding.
Key Tip for Dual Nationals:
- Check passport validity early and ensure you have the right documents for entry into the UK, especially as the transitional flexibility ends in February 2026.
New Entry Requirements for US Travelers: The Mobile Passport Control (MPC) App
Travelers heading to the United States in 2026 will increasingly be required to use the Mobile Passport Control (MPC) app for smoother entry. The app, which allows passengers to generate a QR code for passport control, requires travelers to create a profile, upload a photo, and answer questions upon arrival. While this app speeds up entry at US airports, it adds an extra layer of preparation for travelers.
Key Tip for US Travelers:
- Download the MPC app before departure and complete your profile to avoid delays at US passport control.
Liquids and Medication Rules: What’s Changing at UK Airports?
At Heathrow and some other major UK airports, the traditional 100ml liquid rule has been lifted due to new security scanners. However, this rule is not yet universally adopted, and travelers should still expect to face restrictions on liquids at other airports, particularly for return journeys.
For those traveling with prescribed medication, experts caution that even if the 100ml rule doesn’t apply at Heathrow, it’s essential to carry your medication in original packaging and bring a copy of your prescription. Losing access to prescription medication abroad can cause major issues, so being prepared is crucial.
Key Tip for Travelers:
- Always carry prescribed medication in its original packaging, and keep a copy of the prescription in case of loss or damage abroad.
Expect Delays Beyond Border Control
Nicole Kerr from Mozio warns that the introduction of these new systems won’t be the only cause of delays at airports. Additional challenges such as airport strikes, long queues for taxis, and crowded terminals may exacerbate travel times. Tourists and business travelers alike are advised to plan their journeys with plenty of extra time for unforeseen delays.
Key Tip for Tourists:
- Book transfers in advance and allow extra time for all airport processes, as delays beyond border control are likely in 2026.
What This Means for Your 2026 Holiday
The travel landscape for UK tourists in 2026 will be more complex than ever, with new biometric systems, ETIAS authorisation, and changes to passport rules. However, with the right preparation, travelers can avoid the stress of last-minute complications. Experts advise checking passport validity, applying for travel authorisations early, and staying informed about the latest rules for both departure and arrival airports.
Key Preparation Tips for Tourists:
- Check passport validity early, especially for dual nationals.
- Apply for ETIAS ahead of time for travel to the Schengen area.
- Download the MPC app for US travel.
- Be prepared for delays, and book transfers in advance to avoid last-minute hassles.
By staying on top of these changes and planning ahead, UK holidaymakers can ensure smooth and stress-free travels in 2026.
Key Points (Summary Bullets)
- ETIAS system for UK travelers to Europe starts in late 2026, requiring pre-approval.
- Dual nationals must ensure they travel with the correct passport to the UK.
- MPC app required for US travelers to expedite entry.
- UK airports have lifted the 100ml liquid rule, but other airports may still enforce it.
- Expect delays due to new border systems, airport strikes, and longer queues.
Being prepared is the key to making 2026 travel as smooth as possible, so holidaymakers should check all the necessary steps well before they travel.
