I know one thread has just been closed, but I have just found this on the UKGOV website. It looks like you can ( temporarily) renew a British passport for one year, free, at the Embassy in Bangkok. From tomorrow you can phone for an appointment. Or am I reading it wrong ?

Overseas British passport applications

Get the forms, prices and application details you need if you’re a British national and you want to renew or apply for a British passport from overseas.

If you’re renewing an existing British passport you can apply for it to be extended for 12 months. You won’t be charged any extra fees.

To apply, phone your local British Embassy, Consulate or High Commission and select the ‘Consular Services’ option. Appointments can be made from Monday 16 June.

If you’re the parent or guardian of a child living overseas that needs to travel urgently, you can apply for an emergency travel document for your child instead of a new or renewed passport.

Emergency travel documents are available from the week beginning 16 June in most countries, after checks to confirm nationality and identity. To apply, phone your local British Embassy, Consulate or High Commission

It looks like you can apply, from tomorrow, for a one year extension at the Embassy ?

That topic was closed because there is a long on going topic on the other visa forum about UK passports.

Yes It is now possible to get a 12 month extension of a UK passport. But not if you have already applied for the renewal of one. There is more info on the topic I mentioned.

Not much point in extending the validity if you are trying to get a new passport because your passport is full, though.

If anyone is due to renew a passport it is going to take a minimum of 8 weeks. New passports much longer.

However if you haven't sent your passport in yet,

and your passport is expiring soon,

and you need to travel soon,

and you are a British Citizen or variant passport holder e.g. BPP, BNO, BNSS.

The FCO staff can issue a one time 12 month extension (free o charge) which will run from the date you get the stamp in your passport not adding 12 months to the expiry.
