Thailand visa for UK? No, but 1 thing you must know

If you’re a traveler from the UK wondering, “Do I need a Thailand visa for UK passport holders?” — here’s the quick answer: for most short tourist trips, you don’t. That’s right! UK passport holders can enjoy up to 30 days in Thailand visa-free when arriving by air.

But before you pack your bags, there’s one crucial step you absolutely must not skip: the Thailand Digital Arrival Card (TDAC).

Thailand visa exemption for UK travelers

Under Thailand’s visa exemption policy, UK passport holders can enter Thailand without a visa for up to 30 days when arriving by air. This applies if you’re visiting for tourism or short business trips. So, there is no Thailand visa for UK.

If your stay exceeds 30 days or your travel purpose changes, you should apply for a tourist or other visa in advance through the Thai Embassy or consulate. Check our guide about Thailand visa extensions.

The one thing every UK traveler needs

Here’s the deal: even you don't need a Thailand visa for UK, you still have to complete the UK TDAC online before you fly. The TDAC replaces the old paper arrival form and helps speed up your entry at the airport.

What is Thailand Digital Arrival Card (TDAC)?

The Thailand Digital Arrival Card (TDAC) is a new online form that all visitors to Thailand must complete starting from May 1, 2025. It replaces the old paper TM6 arrival card, making the entry process faster and safer.

All non-Thai nationals entering Thailand by air, land, or sea are required to complete the TDAC online before arrival.

UK TDAC online application steps

When you fill out the Thailand Digital Arrival Card (TDAC), you need to provide some basic requirements like your full name, birth date, nationality, and passport details. You’ll also enter your flight information, arrival date, how long you plan to stay, and where you’ll be staying in Thailand.

Make sure to submit your UK TDAC online within 3 days (72 hours) before you arrive in Thailand. You can do this by yourself or together with your family or travel group.
