The SE postcode area
The SE postcode area is the South Eastern district of the London post town, numbered in 1917. It covers Southwark, Lewisham and Greenwich almost completely and parts of Lambeth, Bexley, Bromley and Croydon, running from the South Bank, Bermondsey and Walworth out through Peckham, Camberwell, Brockley and Deptford to Greenwich, Blackheath, Eltham, Sydenham, Crystal Palace and Thamesmead. Most of the places listed below are in Lewisham, Southwark and Greenwich.
The housing is as mixed as anywhere in London: Georgian terraces in Walworth and Greenwich, Victorian streets across Peckham, Brockley and Lewisham, large post-war estates in Southwark and Thamesmead, inter-war semis in Eltham and Mottingham, and new riverside towers from Bermondsey to Woolwich. Converted houses and estate blocks with shared roofs and stacks are the staple of our leak tracing here.
Pick your district below for the local pages inside it, with the borough page named on each row. Lettered sub-districts sit under their number.
