Lionel William Neeld Inigo-Jones (1885–1956) and his successors remained at their main home, Kelston Park near Bath, and rented Grittleton House to various tenants. During the 1940s the house was used by the MOD to store historical documents. Also during this period, foreign fighter pilots stayed at the house. In 1948 a private girls' school rented the property and in 1967 Joanna Shipp, who had being running her own private day school in Rangeworthy Court, Gloucestershire since 1951, moved into the house. In 1972 she bought the property and began extensive renovations. The Shipp family still owns the house and today it is a venue for special events, particularly weddings.
