Jamie Woodhams was the subject of an investigation by detectives from the Kent and Essex Serious Crime Directorate after a report made to the force in October 2022.
The 51-year-old, of Ashford, has now been charged with six counts of rape and one count of sexual assault.
The charges relate to alleged offences against two women in Kent and elsewhere between 2006 and 2022.
He is also charged with three counts of misconduct in a public office, relating to alleged relationships he formed with women he had met during the course of his duties.
Mr Woodhams, who resigned from the force in April 2022, will appear before Westminster Magistrates’ Court on 27 June.
