There are 38 or so Mail Centres in the UK where all collected mail is taken -- I assume on the same day -- for industrial scale sorting. Our nearest ones are Croydon and Mount Pleasant. [en.wikipedia.org
] But that leaves the question: who does the low level collection from pillar boxes, etc, and do they make any use of the Peckham Delivery Office?
I suspect a friendly postie might be a good source of information. I wouldn't discourage asking RM Enquiries, if only for the opportunity it offereed of expressing concern about Peckham DO. I dare say RM does have figures on numbers of reported losses logged at various centres but would want to keep them confidential. The casess of theft and of mailbags left in a cupboard, that were reported at the recent DCC meeting, were, btw, about the SE21 Delivery Office.
