UK ETA for Mexican Citizens 2026: Requirements and How to Apply

Mexican citizens need a UK ETA to enter Britain in 2026 — a £20 online authorisation tied to your biometric passport that replaces the old wave-through at the border. Mexicans travel to the UK without a full visa for short stays, yet the ETA is now required before you board. Below: who needs one, what it costs, how to apply from Mexico, and what happens on arrival.

TL;DR: A UK ETA for Mexican citizens is mandatory for visits of up to six months. It costs £20, stays valid for two years or until your passport expires, and covers unlimited trips. Approval is usually instant, but allow three working days to be safe.

Key facts at a glance:

• The UK ETA is required for Mexican passport holders visiting for tourism, family or business (gov.uk/eta).
• The fee rose to £20 on 8 April 2026, up from £16.
• One approval allows unlimited entries for two years, with each stay capped at six months.
• Everyone needs their own ETA, including babies and children.
• You apply online or through the official UK ETA app, never on arrival.

Not sure your trip qualifies for the ETA rather than a visa? The UK entry requirements checklist covers the basics, and the gov.uk visa checker confirms your route in under a minute.

Do Mexican citizens need a UK ETA?

Yes. A UK ETA for Mexican citizens is compulsory for short trips, because Mexico is a non-visa country whose passport holders enter Britain without a full visa. Before the scheme launched, Mexicans arrived and were checked at the desk. That check now happens online, in advance, and stays linked to your passport chip.

The ETA covers holidays, visiting family, and short business meetings for up to six months. It does not cover paid work or long courses — those need a proper visa. Hold two passports? Read which passport to use if you hold two before you apply.

Transit matters too. A Mexican traveller connecting through Heathrow to a third country usually still needs an ETA if they pass through UK border control, so check UK ETA transit rules before booking a layover. Getting this wrong at the last minute is one of the most common reasons flights are missed.

How much does a UK ETA cost for Mexican travellers?

The UK ETA costs £20 for each Mexican traveller, a single charge covering two years of trips — roughly MXN 460 at mid-2026 rates. The price went up from £16 to £20 on 8 April 2026, so ignore older figures. There is no family discount: two parents and two children pay £80 in total.

How to apply for a UK ETA from Mexico

Apply online or in the official UK ETA app in about 15 minutes, using your biometric Mexican passport and a payment card. The form asks for passport details, a photo, and short background questions. Most people from Mexico get an email decision within minutes; the Home Office still recommends allowing three working days.

Here is the process step by step:

1. Check your passport. It must be a biometric Mexican passport valid for the trip — check your passport is valid first.
2. Get ready. Have a payment card, an email address, and the items in documents you need to apply.
3. Fill in the form. Enter your details, upload a photo, answer the questions and pay £20.
4. Wait for approval. Track it via check your ETA application status; it links to your passport automatically.

Would you rather not deal with the form? We can check your answers and submit the application for you — a frequent request from families booking for grandparents in Guadalajara or Monterrey who prefer not to apply online. You stay in charge of the plans; we catch the small mistakes that slow things down.

What Mexican passport holders should know at the UK border

At the border, Mexican citizens with an approved ETA use an ePassport gate or a Border Force desk, with the authorisation checked digitally and no paper form to complete. Travellers aged 8 or over can use the eGates at major airports. The gate scans your chip, matches your face, and confirms the ETA in seconds.

Carry proof of your return flight and where you are staying. Officers seldom press Mexican visitors for more, but a brief question about the purpose of your visit is normal, especially on a first trip. Before you fly, the gov.uk travel advice for Mexico is worth a quick read.

Pro tip: Book your ETA before your flights. Approval is usually instant, but a manual check can take up to three working days — and holding off on non-refundable tickets until you are approved removes the only real risk.

Take a Mexico City family flying to London for the October half-term. Each of the four applies a few weeks ahead, pays £20, and is approved within the hour. At Heathrow they head straight to the eGates, tap their passports, and walk through with no form at all — the ETA handled everything in advance.

Practical tips for Mexican travellers heading to the UK

Apply early, stick to the official service, and give every family member their own ETA — those three steps prevent nearly every problem Mexican travellers run into. The rules do not change whether you land in London, Manchester or Edinburgh.

One extra habit helps on a first trip: save a screenshot of your approval email. The ETA is digital and tied to your passport, so you rarely show anything on arrival — but having the confirmation ready answers any check-in question in seconds.

• Time it well. Approval is quick, yet when to apply for your ETA explains why leaving a buffer matters.
• New passport soon? The ETA is linked to your current one, so a renewal means reapplying — start with renewing your ETA.
• Travelling with kids? Each child needs one: ETAs for babies and children.
• Heading north? The same ETA works everywhere — see visiting Scotland with an ETA and travelling to Wales.
• Turned down before? Read what to do if your ETA is refused.

We are an independent assistance service, not a government body. You can apply directly on gov.uk (£20), or use our checking and support service.

Want a second opinion before you pay? Our team reviews and submits your ETA so nothing slips through — useful when you are arranging travel for older relatives who would rather skip the online form.
