Being on the outskirts of south east London it is a convenient commuter town for people who work in the city, as they can still be paid the London living wage. It still keeps some traditional links with Sevenoaks and Kent but it is heavily associated with South East London due to the expansion of that area close to Swanley's borders. The majority of housing development took place from the post-war period to late 1980s. A new fire station was opened in 1962, and new post office two years later. Victorian houses and shops were demolished to create a new town centre. Its 1970s shopping centre was then re-modelled in the 1990s when the Asda supermarket was extended and is one of the larger Asda stores.
