The KT postcode area
The KT (Kingston upon Thames) postcode area is a group of 24 postcode districts across 19 post towns, covering the south west London boroughs of Kingston, Merton, Sutton and Richmond and the north east Surrey boroughs of Elmbridge, Epsom and Ewell, Mole Valley, Reigate and Banstead, Runnymede, Woking and Guildford. It is the area immediately south west of central London, and one that our team covers in depth, district by district.
Each district below lists the places it covers. Every link goes to that place’s own page (the same page you reach through the borough or council listings) so there is one page per place, not one per postcode.
