Nevill was impressed by the September 1909
Crystal Palace Rally of Scouts in London and he established and was the
scoutmaster of the 5th Enfield Boy Scout troop. He helped establish and was a warden and trustee of
Roland House Boy Scout settlement. He was instrumental in the donation of
Gilwell Park to The Boy Scouts Association and, in 1958, he funded the Troop Room at Gilwell Park. In 1948 he donated of cliff land adjoining the sea in
Kingsdown, Kent to create the Kingsdown Boy Scout Camp. He contributed to Scouting publications, translation of scouting publications and wrote two books on Scouting,
My Scouting Story (1960) and
Scouting in London (1966)
The Boy Scouts Association appointments The Boy Scouts Association appointed him as a district
commissioner for East London in 1916, and then a county commissioner. He was the association's headquarters commissioner for kindred societies, to liaise with other organisations, from 1914 until 1949, at the same time as he held other commissionerships and roles. He was also as the association's headquarters commissioner for
Rovers from 1920 to 1930, when he resigned to focus on his other commissionerships. In 1926, the association awarded him its
Silver Wolf. In the early 1960s, when he ended his commissionerships, the association appointed him as a vice president. He disagreed with changes implemented following the 1966 ''
The Chief Scout's Advance Party Report'', particularly the discontinuation of
Rovers and resigned all his active positions with the association but was made honorary commissioner for life.
Roland House In 1916, Nevill moved into Roland House Boy Scout Settlement, at 29 Stepney Green, East London as its warden. The house was the legacy of
Roland Philipps who was killed in action in the
1914-18 World War. Roland House and its Scout Shop were maintained by its wardens, Rovers and resident Boy Scout leaders.
William de Bois Maclaren was a guest of Nevill's at Roland House, which was decisive in De Boise Maclaren's donation of
Gilwell Park to The Boy Scouts Association. In 1920, Nevill took over the full lease for Roland House and all financial responsibility. Upon his marriage in 1926, he moved out of Roland House to Reigate, Surrey. He remained on the Roland House committee until the 1960s.
Rovers Rovers held Nevill's attention and support from the 1920s, soon after its beginning and The Boy Scouts Association appointed him as its headquarters commissioner for Rovers. He organised the first
jamboree for Rovers (which Baden-Powell termed a "moot"). He organised several more moots. After resigning as The Boy Scouts Association headquarters commissioner for Rovers in 1930, he remained involved with Rovers and attended further moots. In 1966, when The Boy Scouts Association discontinued Rovers following ''The Chief Scout's Advance Party Report'', Nevill resigned all his active positions with the association. ==Selected works==
