Received my childs renewal today.
Took exactly 5 weeks and 3 days (you could not count the 3 days as we had 3 bank holidays)
I was asked to send the birth certificate which wasn’t acknowledged on the tracking so after 2 weeks I then used the liverpoolupgradeteam@hmpo.gov.uk address and just give my details and explained after 2 weeks (sending birth cert) I’m worried they might need more information (marriage cert).
1 hour after I sent this email my status updated to approved 29th then printed 3rd then a txt to say out for delivery.
Maybe a coincidence but I think I’ve made someone look at mine to process as it is was straight forward renewal.
Hope this helps someone and goodluck to everyone.
