The United Kingdom’s Electronic Travel Authorisation (ETA) scheme represents one of the most significant changes to UK border and immigration procedures in recent years. Introduced as part of the Government’s wider border security and immigration reforms, the ETA system requires many travellers who previously entered the UK without a visa to obtain advance permission before travelling.

An ETA is not a visa. Instead, it is a digital travel permission linked electronically to a traveller’s passport. It allows the UK authorities to conduct security and immigration checks before a person arrives at the border. Having an ETA does not guarantee entry into the United Kingdom, but it is often a mandatory requirement before boarding a flight, ferry or other carrier travelling to the UK.

Understanding who needs an ETA, how the application process works, and what rights and limitations apply is essential for visitors, family members, business travellers, students and anyone planning a short stay in the United Kingdom.

What Is an Electronic Travel Authorisation?

An Electronic Travel Authorisation is a digital permission that allows certain travellers to travel to the United Kingdom without obtaining a traditional visa.

The ETA system operates in a similar way to travel authorisation systems used by other countries. Before travelling, an applicant submits personal information, passport details and answers security-related questions. The Home Office then considers the application and decides whether permission to travel should be granted.

If approved, the ETA is linked electronically to the passport used in the application. There is no physical document or visa sticker issued. Airline and border systems can verify the permission electronically when the traveller boards transport and arrives in the UK.

The ETA scheme became fully operational across eligible nationalities during the rollout completed in 2025 and has continued to develop through 2026.

Why Did the UK Introduce the ETA System?

The Government introduced the ETA scheme to strengthen border security and improve pre-arrival screening.

Historically, many non-visa nationals could simply travel to the UK and request permission to enter upon arrival. Under the ETA system, basic immigration and security checks take place before travel begins. This enables the authorities to identify potential concerns earlier and reduces the likelihood of inadmissible passengers reaching the UK border.

The system is designed to:

• Improve border security.
• Enhance immigration control.
• Reduce document fraud.
• Allow earlier screening of travellers.
• Support the digitalisation of border processes.
• Align the UK with similar systems used internationally.

Who Needs an Electronic Travel Authorisation?

Most travellers who do not require a visa and who are not exempt from immigration permission requirements will need an ETA before travelling to the UK.

The exact requirement depends upon:

• Nationality.
• Passport held.
• Immigration status.
• Purpose of travel.
• Whether the traveller already has permission to enter or remain in the UK.

Many visitors from:

• European countries.
• The United States.
• Canada.
• Australia.
• New Zealand.
• Various other visa-exempt countries.

will generally require an ETA before travelling to the UK for short visits.

Because eligibility rules can change, travellers should always check the latest Home Office requirements before making travel arrangements.

Who Does Not Need an Electronic Travel Authorisation?

Certain categories of people are exempt from the ETA requirement.

These generally include:

British Citizens

People travelling on a British passport do not require an ETA.

Irish Citizens

Irish citizens travelling on an Irish passport are generally exempt. This reflects the longstanding arrangements within the Common Travel Area.

People Holding a Valid UK Visa

Travellers who already possess a valid visa do not normally require an ETA because they already hold immigration permission.

People With Existing UK Immigration Status

Individuals who already have permission to live, work or study in the UK generally do not need an ETA. This includes many people holding:

• Indefinite leave to remain.
• Limited leave to remain.
• Settled status.
• Pre-settled status.
• Other forms of lawful immigration permission.

What Can Someone Do With an ETA?

An ETA allows travel to the United Kingdom for purposes that would ordinarily be permitted under the visitor rules.

Examples may include:

• Tourism.
• Visiting family and friends.
• Attending business meetings.
• Certain short-term study activities.
• Some permitted professional engagements.

Most visits are limited to a maximum stay of six months at a time. However, the visitor rules continue to apply and travellers must ensure that their activities remain within what immigration law permits.

What Activities Are Not Permitted Under an ETA?

An ETA does not provide unrestricted immigration rights.

Holding an ETA does not normally allow a person to:

• Take employment that requires a work visa.
• Establish long-term residence.
• Circumvent immigration requirements.
• Undertake activities requiring separate immigration permission.

Anyone intending to work, settle permanently or undertake activities outside the visitor rules will usually need an appropriate visa instead.

How Does the ETA Application Process Work?

Step 1: Prepare the Required Information

Applicants generally need:

• A valid passport.
• An email address.
• A payment method.
• A photograph or facial image.

Step 2: Submit the Application

Applications can normally be made online or through the official UK ETA application system. The applicant provides personal details and answers security-related questions.

Step 3: Home Office Assessment

The Home Office carries out automated and manual checks where necessary.

These checks may involve:

• Identity verification.
• Immigration history checks.
• Security screening.
• Criminality assessments where relevant.

Step 4: Decision

Most applicants receive a decision electronically by email. Decisions are often made quickly, although applicants should allow sufficient time before travelling. The Government advises that decisions are usually issued within one day, but applicants should allow up to three working days.

How Much Does an ETA Cost?

As of 2026, the Government fee for an ETA application is £20. Applications are made through official government channels. The fee is generally non-refundable once an application has been submitted.

Travellers should exercise caution when using third-party websites, as some may charge additional administration fees that are significantly higher than the official application cost.

How Long Does an ETA Last?

An approved ETA is generally valid for:

• Two years; or
• Until the passport used in the application expires,

whichever occurs first.

During that period, travellers can usually make multiple trips to the United Kingdom without applying for a new ETA each time, provided the ETA and passport remain valid.

If a passport expires, a new ETA will usually be required for the replacement passport because the authorisation is electronically linked to the passport used during the application.

Do Children Need an ETA?

Yes.

Each traveller generally requires their own ETA, including:

• Babies.
• Infants.
• Children.
• Teenagers.

Parents or guardians may submit applications on behalf of children, but every traveller must hold individual authorisation where the rules require it.

Do Transit Passengers Need an ETA?

Transit rules can be complex.

In some situations, passengers transiting through a UK airport without passing through border control may not require an ETA. However, requirements can depend on the airport, route and immigration arrangements. Travellers should verify the position carefully before departure.

Where border control must be passed during transit, an ETA may be required if the traveller falls within the relevant nationality categories.

Can an ETA Application Be Refused?

Yes.

The Home Office may refuse an ETA application in certain circumstances.

Potential reasons may include:

• Security concerns.
• Criminal convictions.
• False information.
• Immigration abuse.
• Previous breaches of immigration law.
• Other suitability concerns identified during screening.

A refusal of an ETA does not automatically mean that a person is permanently barred from travelling to the UK. In some circumstances, an individual may need to apply for a visa instead, allowing a more detailed assessment of their case.

Does an ETA Guarantee Entry to the United Kingdom?

No.

An ETA only grants permission to travel to the UK. It does not guarantee admission at the border. Border Force officers retain powers to examine arriving passengers and determine whether the visitor requirements are satisfied.

A traveller may still be refused entry if concerns arise regarding:

• Identity.
• Immigration history.
• Purpose of visit.
• Security issues.
• Compliance with immigration law.

Common Problems and Mistakes

Using the Wrong Passport

An ETA is linked to a specific passport. Travelling with a different passport can create significant problems and may prevent boarding.

Applying Too Close to Travel

Although many decisions are issued quickly, delays can occur. Applying well before travel reduces the risk of disruption.

Providing Incorrect Information

Errors in passport numbers, names or other details may affect the validity of the authorisation and could require a fresh application.

Assuming an ETA Is a Visa

Many travellers mistakenly believe an ETA provides the same rights as a visa. It does not. Visitors must still comply with all applicable immigration rules.

Legal Implications of Travelling Without an ETA

Where an ETA is required, airlines and other carriers may refuse boarding if the traveller does not possess valid authorisation. Recent enforcement measures have strengthened the obligation on carriers to ensure compliance before transport begins.

Travelling without the required permission can result in:

• Refusal to board.
• Travel disruption.
• Additional travel expenses.
• Delayed journeys.
• The need to make a new immigration application.

Summary

The Electronic Travel Authorisation scheme has transformed how many visitors travel to the United Kingdom. Rather than obtaining a traditional visa, eligible travellers from visa-exempt countries must now secure digital travel authorisation before departure.

An ETA is not a visa and does not guarantee entry, but it is often a mandatory requirement for travel. It is linked electronically to a passport, generally remains valid for up to two years, and usually permits multiple visits during that period. Travellers should ensure they apply using the correct passport, provide accurate information, and check the latest Home Office guidance before making travel arrangements.

For anyone planning a visit to the UK, understanding the ETA system is now an essential part of complying with UK immigration law and avoiding costly travel disruptions.
