Great to hear that. I applied for my daughters first passport and all the updates are about 1 week after yours. Our flight is 26th and had email Peterborough 3 times since last Tuesday for the upgrade. Still heard nothing.
I will wait till end of the weekend to see if anything happens.
Good to know that they let you collect from London office as well. I hope we can collect the supporting documents at the same time cause we need my husband’s passport back before the flight!!!
