The Guardian, in 1928, praised the book as "a great lark; its author has an agreeable sense of comedy and characterisation, and the gift of writing smart and telling conversation, while his drawings are quite in tune with the spirit of the tale". The newspaper also compared the superficial presentation in the novel to that employed by P. G. Wodehouse.[9] Arnold Bennett hailed it as "an uncompromising and brilliantly malicious satire"[10] and the writer John Mortimer called it Waugh's "most perfect novel ... a ruthlessly comic plot."
In his biography of Waugh, journalist Christopher Sykes recalled, "I was in a nursing home when Decline and Fall came out, and Tom Driberg visited me and brought a copy. He began to read out some favourite passages and was literally unable to read them to the end because he and I were so overcome by laughter."[11]
In a 2009 episode of Desert Island Discs, the British actor and comedian David Mitchell named Decline and Fall as the book he would take to a desert island, calling it "one of the funniest books I've ever read" and "exactly the sort of novel I would like to have written."[12]
