Konta began 2014 at the Shenzhen Open, losing to 15-year-old wildcard Xu Shilin in the first qualifying round. Together with her Austrian partner Patricia Mayr-Achleitner, she reached the semi-finals in doubles, losing to the Ukrainian sisters Lyudmyla and Nadiia Kichenok in straight sets. The following week, seeded third in Australian Open qualifying, Konta won her first match against Grace Min, but lost for the second year in succession in the second qualifying round, in straight sets to Ukrainian Olga Savchuk.
At the start of 2014, she split from Picot for personal reasons. In August 2014, when the LTA decided to close the National Tennis Centre as a base for elite players, Konta began working with Spanish coach Esteban Carril. At the end of 2014, Konta began receiving help from mental coach Juan Coto, a friend of Carril's based in London. A dramatic cut in her LTA funding for 2015 encouraged Konta to move her training base to Gijon in northern Spain, where Esteban Carril and Jose-Manuel Garcia oversaw an increasingly rapid rise up the rankings. Supporters of the LTA's austerity drive argued this was a benefit of their tough love policy, though Konta disagreed that that was the case. After her mental coach Coto died suddenly in November 2016, Konta maintained that she would continue to benefit from his influence: "He’s still very much a part of everything that I do, everything that I will continue to do in this sport and this career. He has gifted me with an incredible amount of tools and habits".
