A document produced by English Heritage and Royal Mail in 2002 which sought to provide a policy for the retention and conservation of all Royal Mail postboxes. It recognised that the “vast majority [of postboxes] make a very significant contribution to the character and appearance of the area in which they are located”. In 2015, English Heritage and Royal Mail, in consultation with the BPMA and the LBSG are seeking to renew and strengthen the policy.
