Drummonds Bank

Andrew Drummond (1688–1769), a goldsmith, founded the bank in 1717. The bank remained within the Drummond family until 1924, when it became known as the Drummonds Branch of the Royal Bank of Scotland. The bank was the Royal Bank's first acquisition south of the Scottish border and continued to be managed by a board of local directors until the 1960s.

In 1992, RBS Holt's branch in Whitehall was absorbed by the London Drummonds branch; it continues to operate as Holt's Military Banking, based in Farnborough, offering personal banking tailored to the needs of navy, army and air force officers. At the same time, the Royal Bank of Scotland revived Drummonds as a specialist in private banking.

The bank offers a variety of services to its private clients, including wealth and asset management. It has been based at its headquarters since 1760. Prior to 1758, the site was occupied by the townhouse, Naunton House. In 1758 the Westminster Bridge Commissioners purchased Naunton House and its neighbouring houses, for the purpose of widening the street. The surplus property was sold to Drummonds for £1,100. The building was reconstructed from 1877 to 1881; Admiralty Arch was built and The Mall laid out nearby shortly after. The building is listed Grade II on Historic England's register of listed buildings.

The bank's focus on wealth management led it to create a specialised department for UK National Lottery winners separate from its more traditional practices.
