Thailand: passport and entry requirements
Thailand lets UK families visit for a holiday without a visa, for up to 60 days. There's still some free admin to sort before you fly, an online arrival card for every traveller, and each passport needs six months' validity left.

Your passport
Each passport has to be valid for at least six months after the day you arrive, and have one blank page. That's counted from your arrival date rather than your flight home, so a passport that runs out soon after the holiday can still be too short on the way in.
Check every passport in the family when you book, not the week before you fly. Children's passports run for five years against an adult's ten, so they come up for renewal sooner and are the ones most likely to be short, and a renewal takes several weeks to come through.
Getting in
British passport holders enter for tourism without a visa and can stay up to 60 days, so there's nothing to apply for or pay in advance. That covers everyone in the family in their own right, whatever their age, and you can extend the stay once by up to 30 more days if you want longer.
Separately from the visa-free entry, everyone has to complete the Thailand Digital Arrival Card, or TDAC, a free online form, in the three days before you arrive. You get a QR-coded confirmation by email to show on the way in. It's one form per person, with no exemption for babies or young children, though a family can fill theirs in together as a single group of up to ten. Do it for everyone before you go, because airlines can turn you away at check-in without it.
Every child needs their own passport, however young, valid as long as the adults' and with a blank page. Each child also needs their own arrival card, filled in with their own passport details. You can add them all to one group submission.
