The first mention of a post office in the village is in 1873. The post office national archives record the issue to Old Warden in April 1890 of a type of postmark known as a rubber datestamp. The village post office closed on 14 October 2008. It was one of about 2,500 compulsory compensated closures of UK post office branches announced by the Government in 2007.

Francis William Bourdillon (1852-1921), poet, translator, bibliophile, and scholar was a vicar of Old Warden of 1880th.

The village is also noted for being the home of the Shuttleworth Trust, an organization committed to the preservation of transport artefacts - primarily bicycles, motor cars, and aeroplanes - produced in the early part of the 20th century. The corresponding collection is known as the Shuttleworth Collection. The estate also has buildings and gardens, and a small airfield from which many of the historic aircraft fly during the regular flying displays. The estate, museum, and airfield are open to visitors. The estate is also the home of Shuttleworth College founded in 1944.
