Moiseiwitsch was appointed a Commander of the Order of the British Empire (CBE) in 1946 for services to music during the Second World War, having performed hundreds of recitals for servicemen and charities.

He married Daisy Kennedy, an Australian concert violinist, and had two daughters, the set designer Tanya Moiseiwitsch and Sandra (1922-1996).

"[9] At the piano, Moiseiwitsch was noted for his elegance, poetry, lyrical phrasing, brilliance, rhythmic freedom, and relaxed virtuosity.

His distinctive style can be heard in his recording of Rachmaninoff's Rhapsody on a Theme of Paganini and the Barcarolle, Ballade No.

[10] He worked meticulously and amicably as a chamber musician, including in Rachmaninoff's Trio Élégiaque and Cello Sonata in G minor.
