That’s it really.
£94.50 for the actual passport, which is alright, I suppose.
£10 for the pictures because you need the fancy digital codes now and can’t just have a picture
£10 for guaranteed postage of the old one back to them, because of course they can’t just have a database that they update to say that one has expired or been replaced.
£115 in total! Bring on the days that it becomes totally digital.
