What You Need to Travel to the UK: A Complete Guide

Travelling to the UK may seem complex, especially with new electronic entry requirements and visa rules. Whether you are going for tourism, business, or a short visit, here’s a clear breakdown of what you’ll need — and how to make sure everything is in order.

  1. Know the Right Entry Permission: ETA or Visa
  • Electronic Travel Authorisation (UK ETA)
    • From 2025, many non-UK, non-Irish citizens (including EU nationals) will require a UK ETA.
    • The ETA allows stays of up to 6 months for tourism, business, short-term study, or permitted paid engagements.
    • It is valid for 2 years (or until the passport expires).
    • Cost: £10 (non-refundable).
    • ETA does not guarantee entry — final permission is given at the UK border.
  • Visa / eVisa
    • If your stay is longer than 6 months, or if you plan to work, study long-term, or reside in the UK, you may need a visa.
    • As of mid-2025, some visas are issued as eVisas, stored in a UKVI online account, without a physical sticker in the passport.

 

  1. Required Travel Documents

To travel to the UK, make sure you have:

  • A valid passport
    • The passport must be the one you travel with and linked to your ETA (if required).
  • ETA application (if applicable)
    • Apply through the official UK ETA website or the mobile app.
    • You need: your passport, a recent photo (digital), email access, and a payment method.
  • Proof of onward or return journey
    • For visit purposes, you may need to prove that you plan to leave the UK at the end of your stay. GOV.UK
  • Travel insurance (strongly recommended)
    • Not always mandatory, but very useful to cover health, cancellations, or unexpected events.

 

  1. Additional Important Considerations
  • Application Timing: Apply for your ETA or visa well before your trip. ETA decisions often arrive within 3 working days, but processing times may vary.
  • Border Checks: Even with ETA/eVisa, border control officers have the final say on entry.
  • Changes in Status:
    • If you renew your passport, you may need to reapply for a new ETA.
    • For visa holders: maintain your UKVI account, as your immigration status may be digital.

 

  1. Common Mistakes to Avoid
  • Waiting too long to apply for ETA/visa — do it well in advance.
  • Not linking ETA with the correct passport — the passport used for ETA must match the one you use to travel.
  • Ignoring airline checks — some airlines may ask for ETA confirmation at check-in, so save a copy of your ETA email.
  • Assuming ETA guarantees entry — you must still satisfy UK border requirements.
  • Not updating your ETA after passport renewal — forgotten to renew ETA = travel risk.
