In some cases rather than leaving a missed delivery notification card Royal Mail / Parcelforce may deliver to a neighbour or leave the item in a safe place around your property. This may be an outdoor bin, outbuilding such as a garage / shed or behind your property out of sight from the street. This is not normal practice but does happen on occasions.
We always advise checking around your property and with close by neighbours. If you cannot locate your parcel please contact our internet department and they will be able to investigate this for you.
