In October 1918, "Africa" returned to the United Kingdom; she went into reserve at Portsmouth in November 1918. Following World War I, "Africa" was briefly the depot ship of the 9th Cruiser Squadron and was employed as an accommodation ship. In December 1919 she was selected to replace the protected cruiser as stokers' training ship at Portsmouth, but this was cancelled. "Africa" was placed on the sale list in March 1920, and was sold for scrapping to Ellis & Company of Newcastle upon Tyne, England on 30 June 1920. She was scrapped at Newcastle.
