Travelling to the United Kingdom in 2026 requires more preparation than in previous years. British authorities have now introduced stricter pre-travel checks and digital authorisations that affect all foreign visitors to the country.
This guide explains the UK’s travel restrictions for 2026, including details on the Electronic Travel Authorisation (ETA) and what’s required for entry. You’ll find all the details you need to help prepare for your trip and reduce the risk of delays or issues on arrival.
UK entry restrictions in 2026: What’s changing?
The UK’s approach to border control has shifted in recent years. Previously, checks were mostly conducted on arrival, but the current system now requires all travellers to prepare in advance. The most significant changes include:
- Mandatory ETA for most visa-free visitors
- Stronger carrier enforcement, meaning transport companies must confirm that you have permission to travel before boarding
- Increased use of risk-based screening, allowing border authorities to carry out checks in advance
The aim of these measures is to prevent travellers without the right permissions from reaching the UK. This reduces the impact at entry points and helps to keep arrivals checks running smoothly, so you can pass through customs and immigration controls efficiently.
When preparing for your UK visit, check if you need a visa or an ETA and apply in advance. Only British and Irish nationals can enter with their passport alone.
UK entry requirements for foreign visitors in 2026
To be eligible to travel to the UK, you must comply with current entry conditions. These include:
- Passport, suitable for international travel and valid for at least 6 months
- UK ETA or visa, depending on your nationality and reason for travel
- Passing UK border, customs, and security checks
These requirements are checked before you travel and at the border. Officials will verify your passport information and eligibility when you apply for an ETA or visa. When you arrive, a border officer will review all of your documentation again.
Important: Having the right documents doesn’t guarantee entry to the UK. Immigration officers make the final decision when you pass through arrivals checks.
Who’s affected by UK travel restrictions?
You must meet the UK’s entry rules whether you’re traveling to major cities like London, Manchester, or Glasgow, or any other area of England, Scotland, Wales, or Northern Ireland. This does not include the Republic of Ireland.
British and Irish citizens are exempt from UK ETA and visa requirements. All other travellers must hold a visa or an ETA to enter the country, regardless of whether they previously travelled visa-free.
If you’re eligible for an ETA, it’s the fastest and simplest way to get permission to come to the United Kingdom. For other travellers, a visa is required — apply through the UK government’s online visa portal.
Do you need an ETA UK to enter the UK in 2026?
Travellers from many countries now need an ETA for the United Kingdom, including the United States, Canada, Australia, New Zealand, and South Africa.
This requirement applies to visitors of all ages, including babies and children. It can be used for multiple entries and is valid for short stays for:
- Business
- Tourism
- Visiting family and friends
If you come from an ETA-eligible country, it’s mandatory for entering the UK in 2026. Without it, you may be refused entry.

UK pre-travel checklist: Making sure you comply with entry rules
To make sure you comply with the UK’s immigration rules for visitors, it’s important to prepare in advance, so you know what’s required. We recommend considering the following 3 areas:
-
Eligibility and legal travel status
Confirm whether your nationality requires an ETA or a visa. This is based on your nationality and your specific travel purpose. Don’t rely on past travel experiences, as the rules have changed for most travellers.
If you need an ETA, it only takes around 10 minutes to apply. Fill out our online form at least a week before you travel, or make a last-minute ETA request if you’re travelling urgently.
-
Passport and carrier checks
Make sure your passport details match your approved ETA or visa exactly by completing your application form with extra care. Your passport must be valid for at least 6 months after you plan to leave the UK.
Airlines, ferry operators, and rail services are required to check travel authorisations before boarding. They may refuse passengers whose details don’t match their ETA or visa, or who cannot produce a valid authorisation.

Questions at the border
When border officers review your documents, they may ask questions about your travel itinerary. These are a regular part of arrivals checks, which help establish that your reason for visiting is genuine and that you’ll leave before your permission to stay expires.
Be prepared to explain the reason for your visit and when you’ll be leaving, if asked. This may include showing proof of onward travel, like your return ticket, or accommodation details.
