Do You Need an Eta to Enter the Uk

If you’re planning a UK trip with children, check every traveler separately. Most people need either a UK ETA or a visa, but the answer depends on the traveler’s nationality, reason for travel, length and type of stay, and whether they already have permission to enter the UK.

A baby may need the same travel authorisation as an adult. A child with a British passport does not. Someone with a UK visa usually does not need an ETA as well.

Use this quick check for each person in your group:

• If they have a British or Irish passport: they do not need an ETA.
• If they already have a UK visa, exempt vignette, or other UK permission: they may not need an ETA.
• If they need a visa for the planned trip: they should follow the visa rules instead of applying for an ETA.
• If they are a non-visa visitor: they need an ETA before boarding, unless a transit or other exemption applies.
• If they are only changing flights without passing through UK border control: an ETA may not be needed.

The rules are changing, so check the official UK guidance and your airline before you leave.

Who needs an ETA to enter the UK

An ETA, or electronic travel authorisation, is for people who can visit the UK without a visa for a short stay of up to six months.

You generally need one when all of these points apply:

1. You are traveling on a nationality that does not require a visa for the planned visit.
2. Your trip fits the short-stay rules.
3. You do not already have UK permission, such as a visa.
4. You will pass through UK border control.

The requirement is tied to the traveler’s nationality and travel purpose. It is not based only on where you live or where your flight starts.

For example, two parents traveling together could have different requirements if they hold different passports or have different immigration documents. The same applies to children traveling with them.

An ETA is also not a replacement for a visa. If your reason for travel or planned stay means you need a visa, applying for an ETA is not the correct route.

A simple family check

Before booking or checking in, ask these questions for every traveler:

• What passport will this person use?
• Are they visiting for a purpose covered by the short-stay, non-visa rules?
• Do they already have a UK visa or another form of UK permission?
• Will they pass through border control in the UK?
• Does the person have a British or Irish passport?

Write down the result for each family member. This avoids a common problem where the adults have completed their paperwork but a baby or older child has not.

Can you enter the UK without an ETA?

Yes, some travelers can.

You may be able to travel without an ETA if:

• You hold a British passport.
• You hold an Irish passport.
• You already have a UK visa.
• You have an exempt vignette.
• You are transiting through the UK without passing through UK border control, where the transit exemption applies.

A visa and an ETA are different documents. If you already have a visa for the trip, you normally do not add an ETA to it. Check that the visa matches the passport you will use and the purpose of your journey.

Transit is the area most likely to cause confusion. A connection at a UK airport does not automatically mean you need an ETA. The key question is whether you will go through UK border control during the connection.

Airline routes, airports and ticket arrangements can affect how a connection works. Ask your airline to confirm your exact transit position before travel.

Do U.S. citizens need an ETA or a visa?

For many short visits, U.S. citizens need a UK ETA rather than a visa. The UK ETA requirement for U.S. citizens traveling for tourism began in the 2025 rollout, and the requirement applies to non-visa visitors under the current system.

That does not mean every U.S. citizen has the same document requirement for every trip.

A U.S. traveler should check the rules based on:

• The reason for the visit
• How long they plan to stay
• Whether they already hold UK permission
• Whether they will pass through border control
• The passport they will use

For example, a U.S. citizen going on a short holiday may fall under the ETA rules. A person traveling for another purpose may need to check visa guidance instead.

Parents should also check children individually. A U.S. passport-holding child may need an ETA even when traveling with parents who have already applied. An infant is not automatically covered by a parent’s ETA.

If you’re asking, “Do U.S. citizens need a visa for the UK in 2026?”, there is no single answer for every trip. The correct document depends on nationality, travel purpose and the planned stay. Use the official UK checker rather than assuming that a previous visa-free trip has the same rules now.

The 25 February 2026 ETA requirement

From 25 February 2026, non-visa visitors must have an ETA before boarding a journey to the UK. This applies regardless of age.

That date matters for families because it removes any assumption that babies and young children are automatically excluded. If a child is traveling as a non-visa visitor and no exemption applies, that child needs their own ETA before boarding.

The boarding check may happen before you reach the UK. An airline can ask for proof that the traveler has the required permission to travel. This means you should not wait until landing to sort out an ETA.

The 2025 and 2026 changes can also create confusion for people who traveled to the UK before. A previous trip without an ETA does not prove that the same family can travel without one now.

Before departure, check:

• The current requirement for each traveler
• The passport details used in each application
• The travel date
• The route and any UK airport connection
• Your airline’s boarding instructions

If the rules changed after you booked your tickets, use the current government guidance rather than relying on an old email, travel blog or past experience.

Children, babies and other family members

A child’s age does not, by itself, remove the ETA requirement. From 25 February 2026, the rule applies to non-visa visitors of every age.

That includes:

• Babies
• Toddlers
• School-age children
• Teenagers
• Adults

Each person needs to be assessed on their own passport and status. A parent’s ETA does not cover the rest of the family, and a child does not become exempt because they are traveling with a British, Irish or U.S. citizen.

Before you travel, make a small family document list:

• Passport for each traveler
• ETA confirmation for each person who needs one
• Visa or exempt vignette details, where relevant
• Any documents linked to existing UK permission
• Flight and transit information

For a baby or toddler, double-check that the passport information in the application matches the document used at the airport. If the child has their own passport, check the requirement for that passport. Don’t assume that a family application works as one shared permission unless the official application process clearly says so.

If a child has a British or Irish passport, that passport changes the answer. British and Irish passport holders do not need an ETA to enter the UK. Use the correct passport for travel and make sure the airline has the right details when required.

Transit through a UK airport: when an ETA may not be needed

You may not need an ETA if you are traveling through the UK and will not pass through UK border control.

This can apply to some passengers who are simply connecting to another country. But the exception depends on how the journey is handled, not just on the fact that you have a connecting flight.

Ask your airline:

• Will I stay in the international transit area?
• Will I need to pass UK border control?
• Do I need to collect and recheck my bags?
• Does my ticket or route require me to leave the transit area?

If you do pass through UK border control, the normal ETA or visa rules may apply. If you are unsure, don’t guess based on the airport name or a short connection time. Confirm the route with the airline before departure.

This is especially useful for families. Moving through an airport with a baby, stroller and several bags can make an unexpected border-control step harder to manage. Checking the transit rules early gives you time to apply for the right document if needed.

Who is exempt from the ETA requirement

The main exemptions to check are:

British and Irish passport holders

A person traveling on a British or Irish passport does not need a UK ETA.

Travelers with a UK visa

If a traveler already has a UK visa, they generally do not need an ETA for that journey. The visa must still fit the reason for travel and the conditions of the planned stay.

People with an exempt vignette

An exempt vignette can also mean that the traveler does not need an ETA. If you are unsure whether a document is an exempt vignette, check the wording on the document or ask the UK government before traveling.

Some airside transit passengers

A traveler who does not pass through UK border control during an onward journey may not need an ETA. The airline can confirm whether the planned connection meets this condition.

These exceptions are why a general country list is not enough. Even travelers with the same nationality can have different requirements because their visas, passports or routes differ.

How to apply and check your ETA before boarding

Use the official UK ETA application and the UK government’s current checker. Avoid relying on an unofficial list of countries. The full answer to “Which countries require an ETA to enter the UK?” depends on which nationalities are currently treated as non-visa visitors and whether another exemption applies.

Apply for each traveler who needs an ETA, including children and babies. Have the traveler’s passport ready, and enter the details exactly as they appear on that passport.

The official guidance is also the right place to check how long it takes to get an ETA for the UK. Processing times and travel rules can change, so don’t plan around a promise from an old page or assume that approval will happen at the airport.

Before you leave home, check:

• Every traveler has the correct document
• Each ETA is linked to the passport being used
• The family has checked the current rules for its nationality and travel purpose
• Any visa or exempt vignette is still valid for the trip
• The airline agrees that the route is covered
• A UK airport connection does not require border control, if you plan to rely on the transit exception

The safest last step is simple: open the official UK ETA application and verify each traveler’s status with the UK government or your airline before departure.
