Travelling to the United Kingdom is set to become more structured from February 25, 2026. Under new border regulations, non-visa nationals will no longer be permitted to board a flight to the UK without first obtaining an Electronic Travel Authorisation (ETA). Airlines will refuse boarding to passengers who do not hold a valid ETA, eVisa, or other approved travel documentation.
The move forms part of the government’s broader strategy to modernise border controls and transition to a fully digital immigration system designed to enhance security while streamlining entry procedures.
What Is the UK Electronic Travel Authorisation (ETA)?
The Electronic Travel Authorisation (ETA) is a mandatory digital travel clearance required for visitors from 85 countries, including the United States, Canada, and France. It acts as pre-travel permission, allowing authorities to screen individuals before arrival.
Key features of the UK ETA are outlined below:
| Feature | Details |
|---|---|
| Cost | £16 per person |
| Validity | 2 years or until passport expiry (whichever comes first) |
| Visits Allowed | Multiple entries |
| Format | Digitally linked to passport |
| Processing Time | Usually within minutes |
| Recommended Application | At least 3 working days before travel |
If a traveller required to obtain an ETA attempts to travel without one, airlines are legally required to deny boarding.
Who Must Apply for an ETA?
Nationals from 85 designated countries must apply for an ETA before travelling to the UK for tourism, business, or short-term visits.
The requirement also applies to:
- Travellers transiting through the UK who pass through passport control
- Visitors making short notice or spontaneous trips
- Individuals attending brief business engagements
However, British and Irish citizens are exempt. They must travel with a valid British passport or, where applicable, a Certificate of Entitlement.
From February 26, 2026, Certificates of Entitlement will be issued digitally rather than as physical documents. Digital versions will remain valid independently of passport expiry dates.
How the UK ETA Compares Internationally
The UK government states that the £16 fee aligns with similar travel authorisation systems worldwide.
For comparison:
| Country/Region | Scheme | Estimated Cost |
|---|---|---|
| United States | ESTA | $40 |
| European Union | ETIAS (expected) | €20 |
| United Kingdom | ETA | £16 |
Like the US and EU systems, the UK ETA aims to strengthen border security by vetting travellers before arrival.
How to Apply for a UK ETA
Applications can be submitted through the official UK ETA mobile app. The process is fully digital and typically straightforward.
Applicants must:
- Provide personal details
- Submit biometric information
- Answer suitability and background questions
Once approved, the ETA is electronically linked to the applicant’s passport.
While most decisions are issued within minutes, authorities recommend applying at least three working days before departure in case additional checks are required.
Since its launch in October 2023, more than 19 million ETAs have been approved.
Revenue and Border Modernisation
As of January 2026, the ETA scheme has generated over £383 million in revenue. The government states that these funds are being reinvested into improving border infrastructure and digital systems.
Officials describe the initiative as a key step in creating a more efficient, secure, and contactless border experience.
Transition to a Fully Digital Immigration System
The UK has been gradually phasing out physical immigration documentation in favour of digital records. Over 10 million eVisas have already been issued.
Travellers holding an eVisa — including individuals under the EU Settlement Scheme — must ensure their UK Visas and Immigration (UKVI) account is updated with current passport information. Failure to do so may lead to delays or boarding complications.
The digital transition aims to:
- Reduce administrative paperwork
- Enhance security verification
- Speed up airport processing
- Improve traveller convenience
What Happens If You Travel Without an ETA?
Passengers required to hold an ETA who fail to secure one before travel will not be allowed to board their flight. The requirement is now mandatory and legally enforced.
Key Points to Remember
| Requirement | Status |
|---|---|
| ETA mandatory for 85 nationalities | Yes |
| Boarding without ETA allowed | No |
| Exempt groups | British and Irish citizens |
| Validity period | 2 years or passport expiry |
| Application platform | UK ETA app |
Final Thoughts
The introduction of mandatory Electronic Travel Authorisations marks a significant shift in how non-visa nationals travel to the UK. While it introduces an additional step before departure, the process is designed to be quick, cost-effective, and entirely digital.
Travellers planning a visit to the UK should verify whether they require an ETA and apply well in advance of their trip to avoid delays.
