What the place is
London’s rich history and vibrant culture are reflected in its diverse districts and landmarks. This guide covers the history of the forgotten postal district of “KW” or “Kentish West,” as well as attractions in Westminster (W1), South Kensington (SW1) and other parts of the city. The area once known as KW is now a mix of residential neighbourhoods, commercial districts and green spaces, while Westminster and South Kensington offer royal landmarks, museums and cultural institutions (Royal Mail History, Visit London).
History
Before the widespread use of postcodes, London was divided into numbered postal districts to make mail delivery easier as the city grew. In 1856, postal reformer Sir Rowland Hill spearheaded the creation of the districts in response to rising mail volumes and pressure on the postal infrastructure.
London was divided geographically, initially into ten districts: EC, WC, N, NE, E, SE, S, SW, W and NW. In 1866, new districts, including “Kentish Town” (K) and “South Western” (SW), were added. “Kentish West” (KW) emerged as a subdivision within the K district. Established in 1866, KW encompassed parts of North West London.
The system was innovative for its time, but as London expanded, district boundaries became increasingly difficult to manage. In 1959, London became the first city globally to implement a more comprehensive postcode system. Its alphanumeric combinations allowed more precise location identification and revolutionised mail sorting and delivery, making the older postal districts largely obsolete.
The KW designation is no longer officially used for postal purposes, but remnants of the old districts can still be found on older buildings and street signs. These “ghost signs” offer a tangible link to London’s postal past. Today, the area historically designated as KW falls under the modern postcodes NW1, NW3 and NW5. “KW” also persists in the names of local businesses and organisations, and in the name of a local newspaper, the Kentish Weekender—a continuing connection to the area’s history and local pride.
