I applied for 2 passports to renew my children’s passports for adult passports (so basically a standard renewal)
Online applications received 14/4/20 one to Durham and one to Peterborough.
Durham: 22/4/20 old passport received
: 15/5/20 approved
: 19/5/20 new passport received
Peterborough: 17/4/20 old passport received
: Still awaiting approval
I guess there is a time difference depending on which office is doing it – some perhaps have more staff than others.
