UK visitors: stricter ETA checks now in force - What you must know before you travel
As of February 25, 2026, British immigration authorities have begun strictly enforcing checks on the Electronic Travel Authorisation (ETA) system.
If you are not a British or Irish citizen and you attempt to travel to the UK without a valid ETA (or visa where required), you will not be allowed to board your flight, train or ferry.
This marks the end of the “adjustment period” that allowed travellers time to become familiar with the new system.
What Is the UK ETA?
The Electronic Travel Authorisation (ETA) is a digital travel permission required for nationals of approximately 85 visa-exempt countries travelling to the UK for short stays of up to six months.
It is:
- Not a visa
- Required before travel
- Digitally linked to your passport
- Valid for two years (or until your passport expires)
- Currently priced at £16
Most applications are approved within minutes, but the UK Government recommends applying at least three working days before departure in case additional checks are required.
Why was it established?
The UK’s Electronic Travel Authorisation (ETA) was set up to modernise and strengthen the country’s border system. At its core, the ETA allows the UK to screen travellers before they depart, improving security, reducing delays and supporting a fully digital immigration system. It was first introduced in 2023 and has been gradually expanded. By 2026, carriers, including airlines, train and ferry operators are legally required to verify ETA status before boarding, making it a fully enforced part of UK border policy.
What has changed?
Until now, enforcement has been relatively flexible to allow travellers time to adapt to the new requirement.
From February 25, 2026 onwards, enforcement is strict:
- Airlines, ferry operators and train services must verify that travellers hold a valid ETA (or visa) before departure.
- Travellers without one will be denied boarding.
- Border authorities will not admit travellers who fail to meet the requirement.
Operators such as Eurostar have confirmed they will enforce the rule. If you are not exempt, you cannot travel without a valid ETA or visa.
This policy follows a “No Permission, No Travel” principle, meaning checks happen before you depart, not just upon arrival.
Who needs an ETA?
You need an ETA if:
- You are travelling to the UK for tourism, visiting family, business meetings or short study (up to six months).
- You are a national of a visa-exempt country.
- You do not already hold a UK visa or immigration status.
Who is exempt?
You do not need an ETA if you:
- Are a British citizen.
- Are an Irish citizen.
- Hold a valid UK visa.
- Have existing UK immigration status.
Dual nationals must travel on their British or Irish passport to benefit from the exemption.
IMPORTANT: Apply with the correct passport
Your ETA is electronically linked to the passport used during the application process.
If you:
- Renew your passport
- Change passports
- Travel with a different nationality passport
You will need to apply for a new ETA.
Airlines will check the passport you present against your ETA record.
What if you stay longer than 6 months?
An ETA only covers short visits.
If you plan to:
- Work in the UK
- Study long-term
- Stay longer than six months
You will typically need to apply for a visa instead. A visa replaces the ETA requirement.
Our final takeaway
The adjustment period is over. From 25 February 2026, UK ETA checks are being strictly enforced.
If you are travelling to the United Kingdom and are not a British or Irish citizen, ensure you:
✔️ Apply for your ETA in advance
✔️ Use the same passport for your application and travel
✔️ Receive confirmation before departure
Without it, you will not be allowed to board.
If you are unsure whether you require an ETA or a visa for your specific situation, always consult official UK government guidance or seek professional advice before travelling.
