Boulter split from Biljana Veselinovic late last year after a three-year partnership in which she won three WTA titles.
The 29-year-old is currently the British number four having fallen out of the world’s top 100.
Boulter has won only three tour level matches since Wimbledon and tore an abductor in her final event of last year in Hong Kong.
As a result she just missed out on a main draw place at the Australian Open. She is currently the third alternate, and without sufficient withdrawals, will need to win through qualifying at Melbourne Park.
But there is still plenty Boulter wishes to achieve, as she made clear in an interview with BBC Sport in November.
“Going forward with a new coach, one thing I’m very clear on is that they are going to be someone who has a lot of experience in how to make it to the very top level of this game,” she said.
“I’ve been ranked as high as 23 and I know I can get back there. I don’t think my level has gone anywhere, I think the consistency needs to improve.
“My goal is not to be ranked 50, 40, 30, 20 – we’ve been there. The goal is to be inside 20.”
On Instagram, Boulter welcomed 2026 as “the best year of her life” – she is due to marry Australia’s world number seven Alex de Minaur.
And she made it clear she will not be mourning the year just gone.
“Adios 2025. Don’t let the door hit you on the way out,” she posted.
