The name is recorded in the Domesday Book of 1086 as Cillesfelle, meaning land of a man called Cēol.
It formed an ancient parish, and later civil parish of 3,378 acres (14 km2), in Kent. It was part of the Bromley Rural District from 1894. The parish included Green Street Green and Pratt's Bottom and stretched as far as Cudham and Orpington. The parish was abolished in 1934 and its former area became part of the Orpington parish and urban district. In 1965 it was transferred to Greater London, to form part of the London Borough of Bromley.
Chelsfield railway station is approximately half a mile west of the village, though on the eastern edge of the more modern area of Chelsfield, which was developed from the 1920s onwards.
Chelsfield Village holds three annual fairs each year. The St. Martin of Tours Church Fete (June), the Chelsfield & Well Hill Produce Show (September), and the Annual Chelsfield Village Fair held in July. This event, in addition to making many thousands of pounds for mostly local good causes, attracts many thousands of visitors and takes good advantage of the rural nature of the surrounding area by saluting the local heritage with flying displays by vintage aircraft, including the Kent Spitfire as part of the event.
The is also an annual Chelsfield Festival of the Arts, numerous live music events at the award winning Five Bells public house, and a programme of theatre presented by The Chelsfield Players.
