In 2003–04 Williams returned to form and was an important part of the Charlton Athletic side who challenged for all three domestic trophies. She started Charlton's second successive FA Women's Cup final in May 2004, but suffered another 3–0 defeat as Julie Fleeting scored a hat-trick for Arsenal. Although Arsenal also pipped Charlton to the League title by a single point, Williams collected an FA Women's Premier League Cup winners' medal when Charlton beat Fulham 1–0 at Underhill in March 2004.
