The first specific reference to the land which later charters, parish, hundred and county maps state to be Kingswood is in the Domesday Book, where a passage in the entry for Ewell states that "2 hides and 1 virgate were removed from this manor; they were there before 1066, but reeves lent them to their friends; and 1 woodland pasture and 1 croft" - Ewell's Lords of the manor in 1086 were Osbern of Eu (held of King William) and King William himself.
Henry II granted it with Shelwood much further detached, in the Weald, as parcel of the manor of Ewell to Merton Priory, who in 1291 were given licence to inclose the wood of Kingswood as "it was their own soil and without the bounds of the royal hunting forest" – see Windsor Great Park.
From Domesday Kingswood, including Lower Kingswood and much of Burgh Heath was a detached part of the parish of Ewell. Between it the Banstead commons of Banstead including what is now Tadworth stretched toReigate forming a buffer particularly for the parish of Walton-on-the-Hill.The wider Copthorne Hundred was a royal hundred. Kingswood by being a liberty was excluded. That hundred around on all sides but the south was worth almost £48 in the 14th century and £136 16s. 4d. in 1636.
Burgh Heath however was recorded, appearing as Burgh, held in 1086 by Hugh of Port of Bishop Odo of Bayeux, his overlord; its assets were 5 exemption units (large estates) for which it was taxed on 2.5.
