Captain Wilfrid Nunn relieved Mitchell on 20 April 1924 before "Ramillies" underwent a refit at Rosyth in June. On 1 November, the Atlantic Fleet underwent a reorganisation that saw the "Queen Elizabeth"-class ships sent to the Mediterranean Fleet and the ships of the 1st Division reconstituted as the 1st Battle Squadron. She decommissioned for an extensive refit at Devonport in September 1926 which concluded on 1 March 1927, when she recommissioned for service. "Ramillies" and her sisters were transferred to the Mediterranean Fleet in August. Captain Hubert Monroe was appointed in command of the ship on 3 February 1928. In August and September, "Ramillies" participated in torpedo and anti-submarine exercises. She took part in manoeuvres simulating a surprise attack in January 1929 and then in combined exercises with the Atlantic Fleet two months later. Captain Bernard Fairbairn replaced Monroe in late April. She went to Jaffa in Mandatory Palestine in October during a period of unrest in the city. "Ramillies" briefly ran aground in Malta's Grand Harbour in January 1930. She steamed to Alexandria in September 1930 in response to rioting there. The ship paid off in June 1932 for another extensive refit at Devonport that lasted until August 1934. In early 1935, the "Revenge" and "Queen Elizabeth" classes again swapped places, though by this time, the Atlantic Fleet had been renamed the Home Fleet. On 16 July, the ships were present during the fleet review at Spithead for King George V's silver jubilee. "Ramillies" accidentally collided with the German steamship in a gale in the Strait of Dover on 31 August; her bow was slightly damaged in the incident.
