Do I need a visa for Thailand with a British passport?
We quote the FCDO text word for word and do not summarise it: its first sentence has conditions or a wording we do not turn into a one-line answer.
From 15 September 2026, if you enter Thailand under the visa exemption scheme, you can stay for up to 30 days for tourism only. Visa-exempt entry does not cover business travel, including attending conferences, meetings or other business activities. If you are travelling for business purposes, you should obtain the appropriate visa before you travel.
Visa-exempt entry for tourism through land-border immigration checkpoints is normally limited to 2 entries per calendar year. This restriction does not generally apply to arrivals by air. If you frequently enter Thailand as a tourist, immigration officials may ask for evidence of your onward travel, accommodation, or sufficient funds, and may refuse entry if they believe you are not a genuine visitor.
If you entered Thailand before 15 September 2026, you will usually be allowed to stay for the period granted when you arrived. If you want to stay longer, you must get the appropriate visa before you travel or, if eligible, apply for an extension through the Thai immigration authorities.
You may be asked to show that you meet the entry requirements. This could include proof that you have enough money for your stay (at least 10,000 Thai baht per person or 20,000 Thai baht per family) and evidence of onward or return travel. British nationals have been refused entry for failing to provide this evidence.
If you overstay your permission to stay in Thailand, you could be fined, detained, deported or banned from re-entering the country. Make sure you understand the conditions of your stay and get any visa extension you need before your permission expires.
If you plan to work, study, retire or live in Thailand, you must get the appropriate visa before you travel.
Digital Arrival Card
From 1 May 2025, all foreign nationals entering Thailand, whether by air, land or sea must complete a digital arrival card online before arrival. Travellers can register for an arrival card within 3 days before they arrive.

Overstaying your visa
If you overstay the period of your visa, you will get a fine of 500 Thai baht a day up to a maximum of 20,000 baht. You risk being:
- held in detention
- deported at your own expense
- banned from re-entering Thailand for up to 10 years
Conditions in detention centres can be harsh.

Check your passport for Thailand
Schengen rules count your whole trip in the Schengen area: if you visit several Schengen countries, enter the day you first enter the area and the day you leave the last Schengen country.
The check runs in your browser: your dates are not sent anywhere. It applies the FCDO sentence literally (for example “6 months” is counted as the same day of the month 6 months later).
For British passport holders only. These are the rules published by the UK government (FCDO) for British citizens. If you hold another passport, check your own government's advice. The airline and the border officials of the destination decide whether you can travel or enter: this site is information, not legal advice.
Blank pages: the official text says “…at least 1 blank page…”. The checker does not count pages.
