Our five boroughs and wider catchment

South East London covers 124 square kilometres and five London boroughs; Bexley, Bromley, Greenwich, Lewisham and Southwark. The region’s estimated 1.9 million residents vary widely in socio-economic indicators, and it is an area of mixed deprivation. South East London includes the more deprived boroughs of Lewisham (7th most deprived out of 33), Southwark (9th), Greenwich (11th), Lambeth (12th) and the less deprived boroughs of Bromley (22nd) and Bexley (23rd). Our three Trusts are working hard together to drive the improvement of services at borough level and across our wider catchment area.
