Katie Boulter will lead the Great Britain team at the Billie Jean King Cup Finals in Shenzhen, China, with Emma Raducanu omitted due to injury and illness struggles. The squad mirrors the side that upset Australia in Melbourne qualifying, featuring Harriet Dart, 17-year-old Mika Stojsavljevic, and Jodie Burrage alongside Boulter.

Britain open their campaign against the Czech Republic on 22 September in the quarter-finals. Captain Anne Keothavong expressed confidence in Boulter's experience and the team's heart shown in April, when Stojsavljevic secured a crucial singles win over world No. 56 Talia Gibson to seal qualification for a fourth finals in five years.

Czechia, 11-time champions, field Wimbledon champion Linda Noskova and runner-up Karolina Muchova. Other contenders include Kazakhstan led by world No. 2 Elena Rybakina, hosts China with Olympic champion Zheng Qinwen, and defending champions Italy featuring Olympic doubles gold pair Jasmine Paolini and Sara Errani. Ukraine and Belgium complete the eight-team field, with all ties decided in a best-of-three format of two singles and one doubles.
