HMS President is a "stone frigate", or shore establishment of the Royal Naval Reserve, based on the northern bank of the River Thames near Tower Bridge in Wapping and is in the London Borough of Tower Hamlets.

This was the 58-gun frigate HMS President, berthed at the West India Docks and training ship of the local Royal Naval Reserve.

The London Division was established on 10 November 1903 and held its first drill night at the Fishmongers' Hall.

She served for nine years as the centre's home, until being paid off on 31 March 1911, and is now preserved in Chatham Historic Dockyard.

This President served until 23 January 1918, when she was lent to The Marine Society, finally being sold on 6 September 1921.

She was joined in 1938 by HMS Chrysanthemum, which served as a drill hall and gave extra space for activities.

President took a number of roles and duties, one of which was to serve as the accounting base for Admiralty personnel.

HMS President has also sited some departments at a number of different locations onshore in the city of London.

As the unit developed, new departments were established and spun off, often taking up residency in buildings across the city.

The Defensively Equipped Merchant Ship accounts were transferred to HMS Vivid on 1 October 1919.

In August 1935, President III also took over the accounts of the Mobile Naval Defence Base Organisation.

It was re-established on 28 August 1939 in Bristol to train those allocated for service on the Defensively Equipped Merchant Ships.
