Betchworth, or Becesworde, is mentioned in the Domesday Book. Its assets in 1086 were listed as: 11 villagers; 16 smallholders; 15 slaves; 1 church; 2 mills; 2 hides (i.e. a unit of land considered sufficient to support a family, equivalent to approximately 30 modern acres depending on the quality of the land); 12 ploughlands; 11 acres of meadow; pastures for 6 pigs; and woodland and herbage for 81 pigs .

Today, slightly more than 1,000 people live in Betchworth. The village has a primary school; a post office and village shop; three pubs; a working forge and a village hall. Parts of its Grade 1-listed church date back to the early 13th century. Betchworth station is situated on the line between Reading and Redhill, from where there is a frequent train service to London Victoria and London Bridge stations as well as to Gatwick airport and the south coast.

The Betchworth Estate has changed hands only twice by purchase since Domesday.  In 1634, the Betchworth Estate was purchased by Sir Ralph Freeman (1610~1655), a wealthy civil judge, Auditor of the Imprests and tin trader whose descendants sold it in 1816 to the Rt. Hon. Henry Goulburn (1784~1856), Chancellor of the Exchequer in both the Duke of Wellington's government (1828) and Robert Peel's second cabinet (1841) and Home Secretary in Robert Peel's first government (1834).

In 1980, the Betchworth Estate was inherited from Major General Edward Goulburn D.S.O. by his cousin The Hon. James Hamilton, later Lord Hamilton of Dalzell (1938~2006), the father of the current owner.

The Betchworth Estate is currently owned by Robert Hamilton, who lives in part of Betchworth House with his family.
