Denmark ETIAS Entry: Updated Requirements for UK Nationals After 2026

Since Brexit, UK citizens have enjoyed visa-free travel to the European Union (EU). This changes in late 2026.

From the last quarter of that year, UK nationals will require an ETIAS authorisation for short stays in Denmark and 29 other countries in the EU’s Schengen Area. Here’s your guide to the new rules.

What is ETIAS and Why it Affects UK Travel to Denmark

ETIAS is the European Travel Information and Authorisation System, a new online pre-screening for visa-exempt visitors. It directly affects UK travel to Denmark because, from late 2026, British passport holders will need this authorisation for short trips to Denmark and most other EU countries.

ETIAS is not a visa but a mandatory digital travel authorisation. You complete a quick online form and pay a small fee before your trip, and the approval is electronically linked to your biometric passport.

This change is a direct result of the UK becoming a third country outside the EU. While visa-free access for short stays remains, the EU is introducing this extra security check for all non-EU nationals who don’t need a visa, including those from countries like Australia and Canada.

Your approved ETIAS allows multiple short trips over three years or until your passport expires. Crucially, it permits stays of up to 90 days in any 180-day period across the Schengen Area, which includes Denmark but calculates stays in Cyprus separately.

Here’s a clear summary:

This system works alongside the new Entry/Exit System (EES), which will digitally record your border crossings. Together, they modernise border control and enforce the 90-day rule, making understanding these Danish entry requirements essential for your next trip.

Who Needs ETIAS to Enter Denmark from the UK?

Most UK passport holders will need an ETIAS travel authorisation to visit Denmark for short stays. You can think of it as a mandatory digital pass, similar to systems used by other visa-exempt countries like the United States.

The General Rule

If you’re a UK national planning a holiday, business trip, or transit through Denmark (leaving the airport), you must apply. This rule applies to all British citizens, including British Overseas Citizens and British Subjects.

Critical Exemptions

You do not need to complete an ETIAS application if you fall into specific categories. Check the list below to see if you are exempt.

• You are a beneficiary of the EU Withdrawal Agreement (e.g., you legally reside in a European country like Denmark).
• You hold a valid residence permit or card issued by Denmark or another Schengen country.
• You possess a valid Schengen visa for your trip.

Special Cases

Family members of EU citizens have a different process. You likely still need the authorisation itself but may be exempt from the €20 fee during the application process.

The table below clarifies who needs what for entry.

Always verify your status before you start your application on the official ETIAS website. Border guards will check for the correct document, whether it’s your ETIAS travel authorisation, residence permit, or visa, when you arrive.

Step-by-Step: The ETIAS Application Process for UK Citizens

Applying for your ETIAS is a straightforward online process you can complete in minutes. You will need a valid passport, a payment card, and some basic personal and travel details to get started.

When and Where to Apply

You must apply via the official ETIAS website or mobile app, not through a third party. It’s wise to apply at least a few days before your trip, though the system is designed for quick decisions.

Documents and Info Required

Gather your biometric passport and a debit or credit card first. You will also need to provide your email address, current occupation, and details about your first point of entry into the Schengen Zone.

Filling the Form and Fees

The form asks for straightforward biographical and passport data. You will pay a €20 fee at the end, though applicants under 18 or over 70 are exempt from this charge.

Most applications are approved within minutes. You will receive the result, either an approved ETIAS travel authorisation or a request for more information, via the email you provide.

Pro Tip: Accuracy is Key

Every character in your passport number must be entered perfectly. A single typo will create a mismatch that could stop you boarding your flight.

Use the table below as a quick checklist before you apply:

Remember, an ETIAS is for short-term stays across the Schengen Zone, which includes popular destinations like France, Croatia, and Spain. Note that Ireland is not part of this zone and has separate rules. Your authorisation is valid for travel to any member state.

Key Rules for Your Stay in Denmark with ETIAS

Your approved ETIAS comes with specific conditions you must follow for legal entry and stay. Understanding these rules is essential to avoid overstaying or being denied entry at the border.

The 90/180-Day Rule Explained

This rule limits your stay to 90 days within any rolling 180-day period across the entire Schengen area. Your time in Denmark counts towards this total along with days spent in other participating countries like Austria, Bulgaria, or Iceland.

Purpose of Stay

Your ETIAS is a visa waiver for tourism, business meetings, or visiting family. It does not grant permission for paid work, long-term study, or seeking employment during your visit.

Border Control Reality

A valid ETIAS authorises your travel but does not guarantee entry. Danish border guards make the final decision and can refuse entry if you fail to meet standard conditions.

They may ask for proof of funds, a return ticket, or your purpose for visiting. This check is a standard part of managing the EU’s external borders.

The table below clarifies what your ETIAS allows and does not allow.

Your eligibility for this system is based on being a citizen of one of the eligible countries, like the UK. The European Commission designed these rules to simplify travel while maintaining border security.

Common Pitfalls and How to Avoid Them

Many ETIAS refusals and travel disruptions stem from simple, avoidable errors. Knowing these common pitfalls can save you time, money, and stress before your trip to Denmark.

Passport Validity Trap

Your passport must be valid for at least three months after your planned departure date from the Schengen Area. It also must not be older than ten years from its date of issue.

Check both dates carefully before you apply. A passport that fails either test can lead to an ETIAS refusal or being stopped at border control.

Mismatched Document Problem

Your ETIAS is electronically linked to the specific passport you use in the application. You cannot transfer it to a new passport if yours is lost, stolen, or renewed.

If you get a new passport, you must submit a fresh ETIAS application. This rule applies for travel to all participating countries, including non-EU countries like Norway and Switzerland.

Last-Minute Application

Although most applications are processed quickly, some require extra checks. If officials request more information or an interview, the process can extend by up to 30 days.

Apply at least a few weeks before your departure date. This gives you a buffer for any unforeseen delays.

Refer to the checklist below to steer clear of these issues.

A final tip is to print or save a digital copy of your ETIAS approval email. Keep it with your travel documents as a handy reference, though border guards will access it electronically.

Ready for Your Next Trip to Denmark?

From late 2026, UK travellers to Denmark will need an ETIAS authorisation, secured via a simple online application. The key to a smooth trip is respecting the 90/180-day rule and preparing early. 

Before you book, check your passport’s validity and bookmark the official ETIAS site to apply once your plans are set. This new step is designed to be quick and digital, ensuring you can continue exploring Denmark and Europe with ease.
