William Inge's share of Eynsford Castle was inherited by the Zouche family and, when the last of the de Criols died in 1461, the Crown granted the Zouches complete ownership.
The castle passed to Lady Elizabeth Chaworth, and on her death in 1501 the Crown gave it to the Harts of Lullingstone Castle.
The Harts-Dykes branch of the family later acquired the lordship of the castle and during the 18th century they used the ruined site for their hunting kennels and stables.

In 1835, the castle ceased to be used as kennels and the architect Edward Cresy was employed to remove the more recent modifications.
As part of this work he surveyed and excavated parts of the castle, removing up to 9 feet (2.7 m) of accumulated debris.
The castle then fell into neglect again, and sections of the north-western walls collapsed in 1872.

A local landowner, E. D. Till, leased the castle in 1897 and undertook restoration work.
Agnes Lady Fountain took over the lease after his death in 1917.
She agreed to a plan to protect the castle, under which she purchased the freehold and transferred this to the Society for the Protection of Ancient Buildings in 1937; then, once the leasehold on the property had expired, the castle was passed into the guardianship of the Ministry of Works in 1948.

The site was excavated by S. Rigold between 1953 and 1961 while the castle was being restored, and again between 1966 and 1967 during work to install a new bridge over the moat.
Subsequent excavations in the early 1980s by Valerie Horsman led to a substantial reassessment of the fortification's earlier history.
In the 21st century, Enysford Castle is controlled by English Heritage and open to visitors; the ruins are protected under UK law as an ancient monument.
