Kartal won her first title in November 2021, at the Antalya $15k event, beating Amarissa Toth in the final. This was shortly followed by her second title (and her first on hardcourt) at Monastir $15k, defeating former world No. 40, Ayumi Morita, in the final.

Kartal won the women's title at the UK Pro League with a 6–0, 6–1 win over Freya Christie in the final. She ended 2021 ranked 993.

She followed up her success in late 2021 early in the 2022 season; winning her third title at the $25k Birmingham event with a three-sets win over compatriot Talia Neilson Gatenby. She won a second consecutive $25k title in Glasgow, beating Czech player Barbora Palicová.

Kartal was part of the BJK Cup team for the qualifying tie in April 2022 when Great Britain faced the Czech team in Prague. However, she was not selected to play any matches.

In May, she won two consecutive singles titles in the third and fourth weeks of the $25k Nottingham events— beating Danielle Lao and Joanna Garland in the finals.

Kartal posted a quarterfinal result at the $60k indoor event in Trnava, losing to the second seed Vitalia Diatchenko. The following week at the $60k Trvana 2, she upset third seed Daria Snigur in the first round, but was forced to retire from her second-round match due to injury. However, these performances allowed her to make her top-200 debut. Kartal ended the year ranked No. 198, almost 800 places above her 2021 year-end ranking.

At the 2023 Australian Open, Kartal lost in three sets to 21st seed Elizabeth Mandlik in the first qualifying round. As a wildcard player, Kartal entered the $60k event in Sunderland, England, falling to former top-30 player Mona Barthel in the quarterfinals.

In June 2024, ranked No. 295, she qualified for the first time at the 2024 Wimbledon Championships, earning a spot in the main draw, having received wildcards in the previous two editions. She defeated 29th seed Sorana Cirstea and world number 45 Clara Burel. She became the second British woman in the Open Era to reach the third round at this Major as a qualifier, and first since Karen Cross in 1997. She lost her third round match to second seed Coco Gauff, going down in straight sets.

In August, Kartal lifted back-to-back ITF W35 GB Pro Series trophies on hardcourts in Roehampton, England, her fourth and fifth titles at that level in the season.

In September, ranked No. 151, having made it through qualifying, she reached the first WTA Tour quarterfinal in her career at the Jasmin Open in Monastir, Tunisia, upsetting fifth seed Jaqueline Cristian, her third Top 100 win of 2024, and Mai Hontama. Next, she defeated Yuliia Starodubtseva in straight sets, and then Eva Lys in the semifinals by retirement, to reach her maiden WTA Tour final. In the final Kartal defeated Rebecca Šramková in straight sets. As a result of her success she broke into the top 100, raising 55 positions up to a new career-high of world No. 96 in the WTA singles rankings for the first time in her career.

Kartal won her sixth ITF title of the year at the W100 Shrewsbury in October, defeating fellow Briton Heather Watson in the final.
