HMS LOCH MORE was laid up in the Sheerness Division of the Reserve Fleet until 1950 when she was brought forward for service with the 5th Frigate Flotilla in the Mediterranean. After refitting she commissioned at Chatham in November that year and before sailing to the Mediterranean carried out A/S training at Londonderry.. The Pennant Number for visual signalling purposes was changed to F639. The ship joined the Flotilla in Malta during March 1951. Later that year she was deployed as Guardship at Aqaba and Port Said. She took part in the Fleet Exercise and Visits Programme with ships of the Flotilla including the NATO Exercise SYMPHONIE DEUX in October.


She was refitted at Gibraltar early in 1952 and rejoined the Flotilla in June to take part in the Fleet Summer Cruise Visits and Exercise Programme including Exercise LONGSTOP. After being nominated for reduction to Reserve she returned to UK and Paid-off at Chatham in February 1953. Although held in Reserve pending Modernisation this was never carried cut and the ship was preserved at North Shields before being laid-up at Hartlepool. She briefly re-commissioned in 1956 after a refit but returned to Reserve after sea trials. An offer made for sale to Ceylon was not accepted and the ship was placed on the Disposal List in May 1961. Sold to BISCO for demolition by  T W Ward in August 1963 she arrived in tow at Inverkeithing to be broken-up on 27th August that year.
