As you may recall last week, it took me sometime to figure out how I could send my current passport back to the UK as required to get a new one, as many courier services said they wouldn’t take passports.
In the end, I was told by HMPO that they could as long as it was direct to them, no-one else. So I sent it with DHL & it arrived in Hemel Hempstead 48 hours later.
The new passport was printed the same day & sent, but the weekend slowed it down, meaning it only arrived today, again by DHL.
