With the ending of the
Women's Cricket Super League in 2019, the
England and Wales Cricket Board intended to launch a new regional structure for domestic women's cricket in England and Wales, including a 50-over competition, a Twenty20 competition and
The Hundred. In 2021, with a return to a full schedule, it was announced in February that the new Twenty20 competition would be called the Women's Regional T20, to run alongside the Rachael Heyhoe Flint Trophy and to be competed for by the same teams. Two days before the tournament began, it was renamed the Charlotte Edwards Cup, with the
first edition of the tournament getting underway on 26 June, eventually being won by
South East Stars. The second edition of the tournament (
2022) was won by
Southern Vipers, who beat
Central Sparks in the final. Vipers retained their title in 2023, beating
The Blaze in the final by 7 wickets. The Blaze won the title the following year, defeating South East Stars in the final after topping the group stage. 2024's was the last edition of the competition as the ECB announced it would be replaced, due to another restructuring of women's domestic cricket in England and Wales. The ECB reversed the regionalised structure of the Charlotte Edwards Cup, and has replaced it with a new
Women's T20 Blast using the county structure. ==Teams==
