In 1919, a committee chaired by the Marquess of Crewe determined there existed the need to separate the agency work of the India Office from its other political and administrative roles, and recommended the transfer of all such work to "a High Commissioner for India or some similar Indian Governmental Representative in London."

[3] The Government of India Act that same year upheld the recommendations of the committee, making provision for "the appointment of a High Commissioner by His Majesty by Order in Council, which might delegate to the official any of the contractual powers of the Secretary of State [for India] in Council, and prescribe the conditions under which he should act on behalf of the Government of India or any Provincial Government."

On 13 August 1920, King-Emperor George V issued the required Order in Council.

The first High Commissioner for India was Indian Civil Service officer Sir William Stevenson Meyer; the first of Indian origin was Sir Dadiba Merwanji Dalal.

The High Commissioner enjoyed the same status as his counterparts from the British Dominions.
