The main sorting office in Bromley closed in 1988 with the site becoming a Delivery Office operation only. The BR area includes much of the London Borough of Bromley, as well as small parts of the London Borough of Lewisham, the Royal Borough of Greenwich and the London Borough of Croydon. Most of BR8 and a small part of BR6 cover the northwestern part of the Kent district of Sevenoaks, while BR8 also covers the hamlet of Clement Street in the Borough of Dartford.
