Planning a trip to the UK? Before you book anything else, you need to sort out your UK ETA. It’s not hard, but a lot of people mess up small details and end up waiting longer than they should. This guide walks you through the whole thing, step by step, in plain language.
What Is a UK ETA, Really?
ETA stands for Electronic Travel Authorisation. Think of it as digital permission to enter the UK. It’s not a visa. It’s more like a quick background check that gets tied to your passport. Once you have it, you can fly, sail, or take the train into the UK without extra paperwork at the border.
If you’re not sure whether you even need one, check our UK ETA eligibility page first. It only takes a minute to figure out.
Something Most Guides Don’t Tell You
Here’s a detail people skip: your ETA gets linked to the exact passport number you use when applying. If your passport expires or you get a new one before your trip, your ETA doesn’t carry over automatically. You’d need to apply again with the new passport details.
So if your passport is close to expiring, renew it first, then apply for the ETA. Doing it the other way around is one of the most common (and most avoidable) mistakes travelers make.
Who Needs to Apply
Not every visitor needs an ETA. It depends on your nationality and the purpose of your trip. Common reasons people apply include:
- Tourism or visiting family and friends
- Business trips, work meetings, or academic visits
- Short-term study
- Medical treatment
- Getting married or forming a civil partnership in the UK
- Passing through the UK on the way to another country
Each purpose has its own small set of rules. If you want the full breakdown, our UK ETA types page covers all of them in detail. There are also dedicated pages for tourism and visiting family, work and business visits, short-term study, medical treatment, marriage purposes, and transit through the UK.
What You Need Before You Start
Have these ready before you sit down to apply. It saves a lot of back-and-forth:
- A valid passport with at least a few months left before it expires
- A clear photo of yourself (your phone camera is fine)
- An email address you actually check
- A debit or credit card for the fee
- Basic travel details, like when you plan to arrive
For the full list of documents and rules, check our requirements page.
How to Apply, Step by Step
- Go to the application form. Fill in your name, date of birth, and passport info exactly as it appears on your passport. Even a small typo can cause delays.
- Upload your photo. Use good lighting, a plain background, and no sunglasses or hats. Blurry or dark photos are one of the top reasons applications get sent back for review.
- Answer the background questions. These cover things like health, past travel, and any criminal history. Answer honestly. If something looks off later, it slows everything down.
- Review everything. Read through your answers one more time before submitting. This is the step people rush through the most, and it’s where small mistakes hide.
- Pay the fee. Once payment goes through, your application is submitted.
- Wait for your confirmation email. Most people hear back quickly, but it can take longer during busy travel seasons.
How Long It Takes and What It Costs
Processing times can shift depending on the time of year and how many people are applying. Fees can also change, so don’t rely on numbers you saw somewhere else months ago. Our processing time and fees page stays updated with the current numbers.
A simple tip: apply at least a couple of weeks before your trip. Most approvals come back fast, but giving yourself a buffer means one slow application won’t wreck your travel plans.
Common Mistakes That Slow Things Down
- Typing your passport number wrong
- Using an old or expired passport for the application
- Submitting a blurry or cropped photo
- Leaving out travel history when asked
- Applying the night before a flight
None of these are complicated to avoid. They just take a little extra care.
