Yeah, the British Embassy in Bangkok (there’s no separate consulate) does provide certified copies of UK passports for British expats in Thailand. It’s a notarial service they offer – you bring your original passport, they photocopy and stamp it as a true copy. Costs around £25-50 usually, but check current fees.
You gotta book an appointment online through their system first – no walk-ins. Some folks say it can even be done by post now for this specific service, but most do it in person. Super common for things like marriage registration, bank stuff, or visa extensions here.
Head to gov.uk for the exact notarial guide for Thailand to book.
