SW3 covers Chelsea in south west London. It is home to around 19,000 people across roughly 9,300 households, with about 340 homes sold in 2025. That gives a steady stream of moves for such a central area. Bordering postcodes are SW1W, SW1X, SW7, SW8, SW10 and SW11.
Every district page on this site is written from real public data: boundaries, neighbouring districts and property records. The best part is written by the mover who claims it.
