Johanna Konta, Heather Watson, Laura Robson and Jocelyn Rae have been named in the British Fed Cup squad for February's matches in Estonia.
It is the first team to be picked by new captain Anne Keothavong.
Two changes can be made before the final selection deadline on 7 February.
"In Johanna Konta we are lucky to have a player who is at the very top of the game right now," said Keothavong of the British number one, who broke into the world's top 10 last year.
"Along with Jo, we have fantastic experience in Heather and Laura, with nearly 40 Fed Cup rubbers between them, and Joss Rae gives us a strong doubles option.
