UK ETA for Transit & Layover 2026: Do You Need One?

Travelling through a UK airport on your way to another destination? Wondering if you need a UK ETA just for a layover or transit? This is one of the most frequently asked questions about the UK ETA system in 2026 — and the answer is nuanced.

Whether you need a UK ETA for transit depends on your nationality, your type of transit, and whether you plan to leave the airport. This guide clarifies everything you need to know about UK ETA requirements for layovers, stopovers, and connecting flights in 2026.

The UK’s transit rules are managed by the UK Visas and Immigration department. Whether you’re connecting through London Heathrow, Gatwick, Manchester, or any other UK airport, understanding the ETA requirements for transit passengers is essential for smooth travel in 2026.

Key Takeaways

• Most travellers from ETA-eligible countries do need a UK ETA for transit — even if staying airside
• Some nationalities may qualify for Transit Without Visa (TWOV) — check eligibility carefully
• If you plan to leave the airport (even briefly), you definitely need an ETA or visa
• UK ETA is valid for both tourism and transit purposes
• Check-in staff verify your UK entry permission status even for connecting flights

Do You Need a UK ETA for a Layover or Transit?

The short answer: Yes, most travellers from ETA-eligible countries need a UK ETA even for transit through UK airports. The UK ETA covers both tourism visits and airside transit at UK airports including London Heathrow, Gatwick, Manchester, Birmingham, and others.

Key fact: The UK ETA costs £16 per application, is valid for 2 years or until your passport expires, and allows unlimited visits of up to 6 months each. Citizens from 48 eligible countries must obtain an ETA before travelling (Source: GOV.UK).

ETA-Eligible Nationality Transiting Through the UK

If you hold a passport from an ETA-eligible country (such as Australia, Canada, USA, Japan, South Korea, or most EU countries), you need a UK ETA to transit through UK airports — even if you remain airside (within the international transit area) and do not go through UK Border Force passport control.

This is because airlines check your ETA status before you board your first flight. If you are flying UK → somewhere else → UK, you need an ETA for each UK leg of the journey.

Transit Without Visa (TWOV) — Who Qualifies?

A small number of nationalities may qualify for Transit Without Visa (TWOV) at UK airports if they meet specific criteria. TWOV allows eligible travellers to transit airside (without passing through border control) without any UK entry permission.

TWOV eligibility in 2026 generally requires ALL of the following:

• You are transiting directly to a non-UK destination within 24 hours
• You have a confirmed onward ticket
• You do not leave the international transit area
• You hold a valid visa for your final destination (if required)
• Your nationality is listed on the UK TWOV exemption list

Check the current TWOV eligibility list on the UK Government transit visa page. Note: many nationalities that previously qualified for TWOV now require an ETA as the ETA requirement has expanded.

UK ETA vs Transit Visa: What’s the Difference?

The UK ETA replaced the previous DATV (Direct Airside Transit Visa) requirement for ETA-eligible nationalities. If you previously needed a DATV to transit through UK airports, you now need a UK ETA instead.

UK Airports Where ETA Transit Applies

The UK ETA (and previous DATV) requirements apply at all major UK airports used for international connections, including:

• London Heathrow (LHR) — busiest transit hub in the UK
• London Gatwick (LGW)
• London Stansted (STN)
• London Luton (LTN)
• Manchester Airport (MAN)
• Birmingham Airport (BHX)
• Edinburgh Airport (EDI)
• Glasgow Airport (GLA)

How Long Can You Stay in the UK on ETA Transit?

The UK ETA allows stays of up to 6 months. For transit purposes, you are expected to stay only for the duration of your connecting flight and reasonable connecting time. However, UK Border Force uses discretion — you are not prohibited from spending a day or two in the UK between flights if you have an ETA.

If you plan to spend time in the UK between connecting flights (for example, a 12-hour or overnight layover), an ETA is perfect — it allows you to leave the airport, visit the city, and continue your journey. You do not need any additional documentation for this.

Cruise Ship Passengers and Port Stops

The UK ETA also applies to cruise ship passengers stopping at UK ports (such as Southampton, Dover, Liverpool, or Tilbury). If your cruise ship docks at a UK port and you wish to disembark, you need a valid UK ETA.

ETA for Eurostar and Channel Tunnel

Travellers arriving in the UK via the Eurostar train or the Channel Tunnel (Eurotunnel Le Shuttle) also require a UK ETA if their nationality is ETA-eligible. UK immigration checks are conducted at the departure terminal in France or Belgium — so your ETA must be valid before you board.

Practical Tips for Transit Travellers

1. Apply for ETA before booking your transit route — confirm you have everything in order
2. Apply at least 72 hours before your first departure (the one that takes you to the UK)
3. Have your ETA confirmation email accessible — useful for any airline questions
4. Check passport validity — ETA links to your passport; expired passport = invalid ETA
5. Check minimum connection time requirements at your UK transit airport

Frequently Asked Questions

Do I need a UK ETA if I don’t leave the airport?

For most ETA-eligible nationalities, yes — an ETA is required even for airside transit (staying within the international departure area without passing through border control). Airlines check ETA status before you board the flight to the UK. The TWOV exemption applies to a small list of nationalities under specific conditions — check the UK government’s transit page.

Do I need a UK ETA for a stopover of just a few hours?

Yes, if your nationality requires one. A 2-hour connection and a 48-hour layover are treated the same — both require a valid UK ETA (for ETA-eligible nationalities). Apply in advance regardless of how short your UK connection is.

Can I visit the UK during a long layover with just an ETA?

Yes. If you have a valid UK ETA, you can leave the airport during a long layover and explore the UK for the duration permitted by your ETA (up to 6 months). An ETA covers both transit and tourism purposes. This makes it ideal for turning a long stopover into a mini-visit.

What happens if I transit the UK without an ETA?

The airline will refuse to allow you to board the flight to the UK. Airlines face fines for carrying passengers without the required UK entry documentation. If you somehow reach the UK without an ETA, UK Border Force will refuse you entry and return you to your departure point.

How much does a UK ETA cost for transit?

The cost is £16 per person as of February 2026 — the same fee for all purposes (tourism, transit, business). There is no reduced rate for transit-only travel. The ETA is valid for 2 years and covers unlimited entries, so one ETA covers both transit and tourism on the same or future trips.

Travelling with children during your transit? Each child needs their own ETA — see our UK ETA guide for children and babies.

Types of UK Transit: Airside vs Landside

Understanding the difference between airside and landside transit is crucial for determining your UK ETA requirements:

Airside Transit (Staying in the Airport)

If your connecting flight departs from the same terminal and you do not need to pass through UK border control, you are making an airside transit. In most cases, airside transit passengers at major UK airports like Heathrow Terminal 5 can connect between flights without entering the UK. However, if you need to change terminals — for example, arriving at Heathrow Terminal 2 and departing from Terminal 5 — you will need to pass through immigration and will therefore require an ETA or transit visa.

Landside Transit (Entering the UK)

Any transit that requires you to pass through UK border control is considered a landside transit. This includes situations where you need to collect and re-check your luggage, change airports (for example, arriving at Heathrow and departing from Gatwick), or leave the airport for any reason. A UK ETA is required for all landside transits for eligible nationalities.

Overnight Connections

If your connecting flight is the following day, you will almost certainly need to leave the airside area and enter the UK. This means you will need a valid UK ETA. Many travellers use overnight connections as an opportunity to explore London briefly — with a valid ETA, you can leave the airport, visit central London, and return for your morning flight.

UK Airports and Transit Facilities

Each major UK airport handles transit passengers differently. Here is what you need to know:

• London Heathrow (LHR) — The UK’s largest airport with five terminals. Airside connections within the same terminal are straightforward, but cross-terminal connections require passing through immigration. Heathrow has dedicated transfer desks and signage for connecting passengers.
• London Gatwick (LGW) — Two terminals (North and South) connected by a shuttle train. Connections between terminals require border control clearance and a valid ETA.
• Manchester (MAN) — Three terminals with airside connections available between Terminals 1 and 3. Terminal 2 connections may require immigration clearance.
• Edinburgh (EDI) — A single-terminal airport where most connections are straightforward, but international-to-international connections may still require border control.

Before booking a connecting flight through any UK airport, check with your airline whether your specific routing requires you to pass through UK border control. Airlines can confirm whether you will need a UK ETA for your particular connection.

Planning Your UK Transit in 2026

To ensure a smooth transit experience through the UK, follow these practical steps before your trip:

• Check your routing carefully — When booking flights, note whether your connection requires a terminal change or airport transfer. This determines whether you need a UK ETA for transit.
• Apply early — Even if you are only transiting, apply for your UK ETA at least 72 hours before departure. The £16 fee and two-year validity make it a worthwhile investment for future UK connections too.
• Carry proof of onward travel — Border officers may ask to see your onward boarding pass or booking confirmation. Having this readily accessible speeds up the transit process.
• Allow sufficient connection time — If your transit involves passing through UK border control, allow at least 3–4 hours between flights to account for immigration queues, especially during peak travel periods.

Conclusion

If you hold a passport from an ETA-eligible country and your travel route passes through a UK airport in 2026, you almost certainly need a UK ETA — even for a short airside connection. The ETA covers transit, tourism, and business visits equally, and at £16 it’s a straightforward requirement to meet.

Apply early — before you book your connecting flights if possible — to ensure your UK transit is smooth and stress-free.
