The following year he undertook a series of paintings of women in interiors, a subject dear to him all his life. He was a conscientious objector during World War I and in 1919 he and his wife moved back to London. In the capital, Harold Knight continued as a portrait painter of well-known society figures and in 1925 was awarded a Silver Medal for his portrait of Ethel Bartlett at the Paris Salon. He was elected President of the Nottingham Society of Artists, 1936-1946 and he exhibited regularly at the RA and RP. He was elected an Associate of the RA, 1928, and RA, 1937, each time a year after his wife. He also exhibited at the Leicester Galleries, ROI, RP, RWA and NSA. Examples of his work are in the collections of art galleries in Auckland, Brisbane, Dunedin, Perth, Wellington, the Royal Cornwall Museum, Truro, Penlee House Museum, Russell-Cotes Art Gallery & Museum, Bournemouth, Nottingham Art Gallery, Brighton & Hove Art Gallery and the Tate Gallery, London.
