I am regularly contacted by people asking if a relative's service within the ARP / Civil Defence are held in archives. In my experience visiting archives, the vast majority of local archives have not retained documents concerning individual members (unless they were senior in the various services). However, one archive that does have a rich seam of information is Wandsworth Heritage Service archives in south London.
Below is one sheet from Battersea Borough Council's file concerning "Identification of Civil Defence Personnel". For those undertaking family history research this can provide long lost detail into the role played relatives during the war.
I am indebted to Raymond Sweetman for the image and information.
