please cut back on the insults as there was a very good reason for this qustion
when people have done or doing there revisions what takes precedence is the royal mail security process. bet the planners never told you that.
your delivery needs to be labeled as small, medium, or high risk for the integrity of the mail.
town deliveries use a hct, but within an urban enviroment you will have a high risk area. a block of flats that have a drug dealing reputation for example.
in this sinario, if the hct is out of sight for more than five minutes then the contents of the hct have to be removed and placed in a van. when the postman has delivered then the contents are placed back from the van into the hct. FACT
THE PLANNERS ARE STATING DIFFERENT IN THAT YOU CAN CHAIN UP THE HCT, TRANSFER ANY SPECIALS INTO, AND USE A POUCH
