As of 01 July 2022:
If you’re fully vaccinated
If you’re fully vaccinated, you must travel with your Certificate of COVID-19 Vaccination.
Proof of vaccination status
Thailand will accept the UK’s proof of COVID-19 recovery and vaccination record. A digital certificate or a screenshot of evidence of your COVID-19 vaccination status should be accepted. Your final vaccine dose must have been administered at least 14 days prior to travel. Your NHS appointment card from vaccination centres is not designed to be used as proof of vaccination and should not be used to demonstrate your vaccine status.
If you are under 18 and travelling with your parents you are exempt from this requirement.
If you’re not fully vaccinated
If you are not fully vaccinated, you still need to apply for a Thailand Pass and ensure you have an insurance policy with coverage no less than US$10,000.
Please note requirements can change with little notification - please double check entry requirements with the relevant embassy before travelling.
