Assistant Commissioner of Police of the Metropolis

Assistant Commissioner of Police of the Metropolis, usually just Assistant Commissioner (AC), is the third highest rank in London's Metropolitan Police, ranking below Deputy Commissioner and above Deputy Assistant Commissioner. There have usually been four officers in the rank; however, at times there have been five to seven and, as of June 2025, there are six owing to the continuing secondment of Stephen Kavanagh to Interpol.

From 1 September 2016 the salary is £198,823 (plus £2,373 allowance). This does not include use of private car and pension contributions. This makes them the equal fifth highest paid police officers in the United Kingdom, behind the Commissioner, the Deputy Commissioner, the Chief Constable of Police Scotland, and the Chief Constable of the Police Service of Northern Ireland, and alongside the chief constables of West Midlands and Greater Manchester.
