Its perhaps opportune to add this point which hasn't actually changed, but is often forgotten or deliberately incorrectly handled.
With the increase in the amount of remote purchasing where goods have to be delivered, if there is a problem with the delivery (e,g. non delivery, missed date/time, or transit damaged goods) then the person who contracts the carrier who is responsible to sort it out as they have contracted the carrier. This applies as much to the postal systems as much as parcel carriers.
Where the new legislation may make a difference is to down to the common practice of many carriers who ask the recipient for a signature which confirms its arrival , but is also used by the carrier to signal the consignment has arrived in good order.
In many situations it is simply not possible for the recipient to have time to check the condition of the goods before signing. I have usually signed and added "Goods not checked" to leave my options open.
I suggest that carriers using this practice should be challenged about this signing practice as it is an unfair term.
