Thailand visa for British citizens 2026: 30 days visa-free

What changed for British citizens on 15 September 2026

Until 14 September 2026, British citizens arriving in Thailand without a visa were stamped in for 60 days. A Ministry of Interior regulation published in the Royal Gazette on 31 August 2026 cut that allowance, and from 15 September 2026 the visa-free stamp for British passport holders is 30 days instead. If you were already stamped in before the change took effect, your passport keeps the original 60 days — the new rule only applies to entries from 15 September 2026 onward. In practice, this halves the time British citizens can spend in Thailand on a single visa-free entry, so trips that once fitted comfortably inside 60 days now need tighter planning, an extension, or a different visa route if you want to stay longer.

Before you fly

• Check your passport has at least six months of validity left from your arrival date in Thailand, plus at least one completely blank page for the entry stamp.
• Book or confirm an onward or return flight, since immigration officers can ask British citizens to show proof they intend to leave within the 30-day visa-free period.
• Carry evidence of at least 20,000 THB per person, or 40,000 THB for a family, in case Thai immigration carries out a spot check on arrival.
• File the Digital Arrival Card through the Immigration Bureau's portal within 72 hours before your flight lands, since every British passport holder must submit it regardless of visa status.

Staying longer than 30 days

If 30 days isn't enough, British citizens can apply for a single extension of up to 30 days at a Thai immigration office, which costs 1,900 THB and must be lodged before the current stamp runs out. For a longer or repeat trip, applying for an e-Visa at thaievisa.go.th before you fly gives a 60-day single-entry stay, also extendable once by 30 days for the same 1,900 THB fee. Remote workers or those on a long course can look at the Destination Thailand Visa instead, which runs for five years with up to 180 days per entry. Repeatedly leaving and re-entering Thailand to reset the visa-free clock isn't a stable option, since land crossings on this basis are limited to two per calendar year.

At the airport

At Suvarnabhumi, British citizens are among the nationalities allowed to use the automated arrival gates, provided you've filed the Digital Arrival Card, entered visa-free, and this isn't your first visit to Thailand. At the gate or the staffed counter, the officer scans your passport and the QR code from your Digital Arrival Card confirmation, so keep it ready on your phone or printed. First-time visitors and anyone without the card still go through a manned immigration counter for the same checks.
