Thailand entry requirements for travellers from the UK

Visa Requirement Summary

UK passport holders do not need a visa for short trips to Thailand. British Citizens travel under Thailand’s visa exemption scheme, which allows tourist visits of up to 60 days without applying for a visa in advance. This covers travel to Bangkok, Phuket, Chiang Mai, Krabi, Koh Samui, Pattaya, and the rest of the country.

If you are travelling for work, study, retirement, or a longer stay, you should apply for the appropriate visa before you travel.

How long travellers can stay

UK travellers can stay in Thailand for up to 60 days per visit under the visa exemption.

You can apply to extend that stay by 30 days at a Thai immigration office for a small fee, bringing the maximum continuous stay to 90 days. Extensions are not automatic and must be applied for inside Thailand before your current permitted stay ends.

Passport validity requirements

Your passport must be valid for at least six months from the date you arrive in Thailand. Travellers with less validity can be turned away at check-in or on arrival, so it is worth checking the expiry date well in advance.

Blank passport pages

You should have at least one blank passport page for the entry stamp.

Proof of funds

Thai immigration may ask you to show that you have enough money for your stay. Not every traveller is asked, but the published benchmark used in Thai visa guidance is 20,000 baht per person or 40,000 baht per family. Having access to that amount in cash, card balance, or a recent bank statement is sensible.

Onward or return travel requirements

You may be asked to show an onward or return ticket before boarding or on arrival. This is a routine check in Thailand and is most likely to come up at the airline check-in desk, so keep your booking easy to access.

Entry forms and declarations

You must complete the Thailand Digital Arrival Card (TDAC) before entering the country. The TDAC is an online form, not a visa, and it has replaced the old paper TM6 arrival card for all international arrivals — air, land, and sea.

The TDAC should be submitted within three days before your arrival. It is free, and applications go through the official Thai Immigration Bureau website. Once submitted, you receive a confirmation that immigration can check on arrival.

Health requirements

There are no routine vaccination requirements for travel from the UK to Thailand.

A yellow fever vaccination certificate is required if you are arriving from, or have recently passed through, a country where yellow fever is a risk. This rarely applies to travellers coming directly from the UK but can affect trips combining Thailand with parts of Africa or South America.

Other entry requirements

Thailand’s visa exemption is intended for tourism and other short visits. Working, including remote work for a foreign employer in some circumstances, can fall outside what visa exemption allows, so use the appropriate visa if your trip involves anything beyond ordinary tourism.

Thailand has strict laws on drugs, including some prescription medicines. E-cigarettes and vapes are banned and can be confiscated on arrival.

Thailand also operates an e-Visa system for travellers who do need a visa in advance.
