Just though I'd post about the positive experience I had recently.
All four of our passports had expired, so even though we only go away later in the year, I was a bit concerned about the turnaround, so decided to get them in early.
Completed the online forms which took 45 mins max for all four.
Got email telling me to send off our old ones so sent them Tracked. They got there two days later and I got an email to say they had received them.
Five days or so later, got emails saying three had been approved, but one of the kids picture needed to be confirmed, so we asked someone to go online to confirm. Again, once that was done, got another email saying that had been approved.
Got emails telling me they were being printed a few days later.
Got emails telling me they were on the way and with tracking numbers.
In total, I reckon just over two weeks from initial applications to receipt of new passports.
The service was superb.
COSTS?
PASSPORTS: £88.50 (x4) = £354
NEW PICS: £50 approx. We did them at Max Spielman to ensure we had correct images (missus nagged me...I didn't want to!), but nothing stopping you taking your own.
SENDING OLD PP's back: £15
Not cheap, but just wanted to let people know it was a very positive and stress-free experience.
