I had to renew my British passport in Bangkok this week. As it was different from my last time, I thought I would share with you the steps that I took to do this. It was all very straightforward to do and I had my new passport back within three weeks. To renew your British passport, you need to first book an appointment by sending an email to BangkokHMPO@vfshelpline.com. In your email, include your first name and last name and three alternative dates and times from 8:30am to 4pm, Monday to Friday except for public holidays. You will receive an email confirming your appointment.
In the same email, they will caution you about following advice in blogs about how to renew your passport! They suggest you check this link if applying from abroad for a new passport: https://www.gov.uk/government/publications/overseas-passport-supporting-documents-group-2 By the way, if something does change, please post
