Former childhood coach Cavaday, who has known her since she was 10 years old, proved a more stable presence.
In December, Raducanu said she enjoyed the continuity she felt with Cavaday, adding it was not her “philosophy to chop and change coaches”.
“I’ve never really wanted that. In the past, unfortunately, it hasn’t always worked like this,” she told a small group of British reporters at the National Tennis Centre.
“When I enjoy it, and it’s a good energy, then it’s a nice feeling.
“I also see how much I’ve developed in the last year as well, on and off the court.”
Cavaday, 38, worked with Raducanu up to the Australian Open, where she lost in the third round.
Since leaving Melbourne, Raducanu has travelled to Singapore for a WTA 250 event with fitness trainer Yutaka Nakamura.
“I am very happy to have been able to work with Emma over the last 14 months,” said Cavaday.
“At this moment in time, it’s important for me to spend some more time at home and prioritise getting back to full health which is hard to do with the extensive calendar.
“I am glad Emma is back to being established on tour now with a ranking inside the top 60, and I look forward to seeing what she does from here.”
