What Is the UK Electronic Travel Authorisation, and What Happens If You Arrive Without One?

A New System at the Border

The UK’s approach to border management changed significantly in 2023, and the pace of that change accelerated in early 2026. The Electronic Travel Authorisation (ETA) is now a mandatory requirement for the vast majority of visitors who do not need a visa for short stays. If you are an American, Canadian, French, or Japanese national travelling to the UK for tourism or a family visit, you need one before you board.

The ETA is not a visa. It does not give you permission to remain in the UK, and it does not grant any immigration status. What it does is allow you to travel to the UK in the first place. The Home Office describes it as a digital permission to travel, and that description is precise. Entry at the border remains a separate decision, made by a Border Force officer on arrival.

The scheme has been building since October 2023, when it first applied to Qatari nationals. By January 2025, it covered most non-European nationalities. From 2^nd April 2025, EU citizens were brought within the scheme. Full enforcement, meaning carriers actively blocking passengers without valid permission, began on 25^th February 2026.

What the ETA Is and How It Works

From 8^th April 2026, an ETA will cost £20. It covers multiple journeys to the UK and remains valid for two years or until the holder’s passport expires, whichever is sooner. Most applicants receive an automatic decision within minutes through the UK ETA app, available on the Google Play and Apple App Stores. A small number of applications require further review, and the Home Office recommends applying at least three working days before travel.

To apply, you need to provide contact and passport details, a digital photograph meeting the government’s photo rules, and answers to a set of suitability and criminality questions. The information is checked against security databases. If no adverse information is found, the ETA is granted automatically. If concerns arise, a decision maker reviews the application, and refusal is mandatory where the suitability criteria in Appendix ETA are not met.

The ETA is linked to the specific passport used to apply. Travellers must travel on that passport. It does not create any right to reside, work, or study in the UK. It is, in the government’s own words, an authorisation to travel, not an authorisation to enter.

Who Needs an ETA when travelling to the UK?

The requirement for an ETA applies to non-visa nationals, meaning nationals of countries who can ordinarily visit the UK for short stays without applying for a visa in advance. That category now includes citizens of EU member states, the United States, Canada, Australia, and dozens of other countries. Since 2^nd April 2025, almost every visitor travelling to the UK without a visa needs an ETA.

The following groups do not need an ETA:

• British citizens and Irish citizens, including those with dual nationality
• British Overseas Territory Citizens travelling on a BOTC passport
• People who already hold a UK visa, eVisa, or other permission to enter or remain
• People exempt from immigration control
• Those transiting airside (without passing through UK passport control) at Heathrow and Manchester, on a temporary basis
• Non-visa nationals who are lawfully resident in Ireland and travelling within the Common Travel Area, provided they can show proof of legal residency in Ireland

The position of dual British citizens deserves attention. Because British citizens cannot be issued an ETA (statute prohibits the government from imposing immigration controls on British citizens), a dual British national travelling on their other passport may face refusal at the boarding gate. The Home Office has been clear: dual British citizens must travel on a valid British passport or Certificate of Entitlement. Carriers are required to enforce this.

How the ETA Replaced the BRP

The Biometric Residence Permit was, for many years, the standard physical proof of immigration status for migrants living in the UK. A credit-card-sized document containing biometric data, it was issued to people on work visas, student visas, family routes, and settlement applications. It also served as a travel document, allowing holders to show carriers and border officials that they had valid leave.

The eVisa has now replaced the BRP. This is an online record of immigration status held in a UK Visas and Immigration (UKVI) account, linked to the holder’s passport. Proving immigration status now means sharing a digital record, using a Home Office share code or allowing an employer or landlord to conduct an online right-to-work or right-to-rent check. The ETA fits alongside the eVisa. The latter is for people who have existing UK immigration status (a Skilled Worker Visa, Settled Status, or similar), while the ETA is for visa-exempt visitors who previously needed no advance permission at all.

The practical consequence is that there is no longer a physical document that demonstrates your right to board a flight to the UK. Everything runs through digital verification, and carriers check against Home Office records automatically using the Advance Passenger Information system.

What Happens If You Travel Without An ETA or eVisa?

Short answer – you will be refused boarding. Carriers are now equipped with automated tools to verify digital travel permissions against Home Office records. When a passenger checks in or presents at the gate, the carrier’s system queries the Home Office database. If no valid ETA, eVisa, visa, or exemption appears, the carrier receives a ‘no record of valid permission to travel’ response and is required to refuse boarding.

For travellers who do manage to arrive at a UK port of entry without valid permission, the position is the same as it has always been under the Immigration Act 1971: a Border Force officer can refuse leave to enter. Refusal is recorded on the traveller’s immigration file and is visible to future immigration decision-makers. Depending on the circumstances, a refusal can affect future visa applications, and serious cases involving deception can lead to a re-entry ban of up to ten years under paragraph 320(7A) of the Immigration Rules.

If an ETA application is rejected, the applicant is told the reason and may apply again. If the application is refused on suitability grounds, no appeal is available. The correct route is to apply for a visa if the person still wishes to travel to the UK.

Grounds for Refusal Of An ETA

Refusal is mandatory under Appendix ETA where certain criteria are met. The main grounds are:

• The applicant is subject to a deportation or exclusion order, or a decision to make one
• The applicant has a criminal conviction resulting in a custodial sentence of 12 months or more, or where less than 12 months have passed since the date of conviction
• The applicant has a relevant history of UK immigration non-compliance at age 18 or over, including overstaying, illegal entry, breach of conditions, or use of deception

The immigration non-compliance ground includes defined tolerances. Where the Home Office subsequently granted entry clearance or permission with knowledge of the breach, or where any overstay was within the permitted short tolerance, refusal is not automatic. Each case turns on its own facts, and the rules themselves should be read carefully before assuming refusal is inevitable.

Practical Steps Before You Travel

• The application process takes minutes in most cases. Apply through the official UK ETA app or via GOV.UK. Avoid third-party websites, which may charge considerably more than the government fee and sometimes impersonate official services. Check that you are using a passport that matches the details you submit once an ETA is linked to a passport, you must travel on that document.
• If you have a criminal record or a previous immigration history involving any of the matters described above, take legal advice before applying. A refusal on suitability grounds closes off the ETA route and requires a full visa application, which carries its own scrutiny. Better to understand your position in advance than to find yourself refused at the gate.
• For employers and HR teams arranging travel to the UK for foreign nationals, the change since February 2026 is material. Visitors from countries that previously required no documentation now need an ETA in place before they book flights. Build ETA checks into travel booking processes, and allow at least three working days lead time, more if the traveller has any history that might require further review.
• People living in Ireland who are nationals of visa-exempt countries should be aware of the Common Travel Area exemption. Provided they can show proof of lawful residency in Ireland, they do not need an ETA to travel to the UK within the CTA. This exemption does not apply if they are travelling from outside the CTA, for example, if flying into the UK from a country other than Ireland.

Frequently Asked Questions

Do I need an ETA if I already have a UK visa or settled status?

No, if you already hold a UK visa, eVisa, indefinite leave to remain, or settled status under the EU Settlement Scheme, you do not need an ETA. The ETA is for visa-exempt visitors who have no existing UK immigration permission. If your status is linked to a UKVI account, carriers will verify it through the same digital system.

I am a dual British and American citizen. Do I need an ETA?

No, you do not need an ETA as a British citizen. However, you must travel on your valid British passport or Certificate of Entitlement. Travelling on your American passport alone may result in boarding refusal, because the carrier’s system will not find a valid ETA linked to that passport and cannot issue an ETA for a British citizen.

My ETA application was refused. Can I appeal?

No, there is no right of appeal against an ETA refusal. If your application is refused, you can consider applying for an appropriate UK visit visa, which does carry appeal rights in certain circumstances. The reason for refusal will be communicated to you, and taking legal advice at that stage is sensible before making any further application.

I lost my BRP card. Do I need to get one replaced?

No, BRPs are no longer issued. If you had valid leave tied to a BRP and have not yet set up a UKVI account to access your eVisa, you should do so. Your immigration status has not changed, but the way you prove it has. Without access to your digital status record, airlines may refuse to carry you, and you may face difficulties at the UK border.

The ETA fee is going up in April 2026. Does my existing ETA remain valid?

Yes, an ETA granted under the current £16 fee remains valid for two years or until your passport expires, whichever is earlier. You do not need to reapply simply because the fee has increased. The new £20 fee applies to applications made from 8 April 2026.
