The consent rules are part of the Sexual Offenses Act of 2003 but the Home Office said low conviction rates across Britain are probably the fault of ignorance of the law.
Sky News reports radio ads will start running March 14 and posters will be placed on bar and club restroom walls.
The Sexual Offenses Act of 2003 prohibits sex without gaining a partner's consent. That consent must be made freely and the person needs to be able to make that choice.
Solicitor General Mike O'Brien said rules to clarify the law may be added to point out when a person is too drunk to give consent.
"Giving consent is active not passive and it's up to everyone to make sure that their partner agrees to sexual activity," O'Brien said.
