Deol accepted the role after being impressed by what was pitched to him by the producers, and being excited to be a part of the show's first Punjabi Sikh family.

Kheerat's storylines in the serial have included the expansion of his family, helping to bring justice to Gray Atkins (Toby-Alexander Smith) with help from Whitney Dean (Shona McGarty), his friendship with Ben Mitchell (Max Bowden), his romances and flings with several female characters including Chantelle Atkins (Jessica Plummer), Sharon Watts (Letitia Dean), and Stacey Slater (Lacey Turner), and falsely confessing to the murder of Ranveer Gulati (Anil Goutam) to save his mother, Suki Panesar (Balvinder Sopal), from arrest.

They plan to run away together but Kheerat is devastated to learn that she has died in a tragic accident, aware that Gray was behind the death to some extent and being accusatory towards him.

He later has a one-night stand with Stacey Slater (Lacey Turner) after they spend a night drinking and confiding in each other about their relationship woes.

After Vinny attacks Martin Fowler (James Bye) and it is revealed that Jags is in a secret relationship with Habiba Ahmed (Rukku Nahar) and no longer wants to be involved in the family business, Kheerat is dismayed to learn that his mother Suki Panesar (Balvinder Sopal) has arranged for Jags to be arrested for Vinny's crime.

Habiba leaves Walford and when Kheerat discovers she is pregnant he decides to pay for her flat and out of guilt for what his mother has done.

When Ranveer's body is uncovered, Suki is arrested for his murder, Kheerat tells her girlfriend Eve Unwin (Heather Peace) that he is planning to confess to the murder to save his mother from prison, and despite both Stacey and Suki pleading him not to, he remains adamant and is later arrested, to the dismay of his loved ones.

[3] He was pleased to gain the part: "I'm very proud and excited to be joining such an iconic show and bringing to life a character that is a reflection of the cultural background that I and many others come from in today's modern Britain.

[9] Upon their introduction, it is established that Kheerat, who is age 31,[5] is the oldest of his siblings and a "flashy"[4] and "successful businessman", which creates envy from his brother Jags.

[5] Sen billed them as "loveable rogues" and "wheeler dealers" over being hardened criminals, and teased the brothers bringing "a completely different tone and flavour" to the serial[5] and being prone to "ruffle feathers".

[13] Executive producer Jon Sen commented that Kheerat and his siblings had "lived under the shadow of an overbearing matriarch" and teased that while the brothers "arrived as men", Suki's introduction would show that they were "little boys who need their mum".

[11] Following Chantelle's death, Kheerat was set to share his suspicions about Gray to her father, Mitch Baker (Roger Griffiths).

[19] Ben had stolen Kheerat's expensive car, and the siblings wanted to show him who was boss leading to a dramatic feud.

"[12] Ben's guilt lead him to try distancing himself from Kheerat by admitting he doesn't want his business partnering involved in the Arches anymore.

[21] Deol admitted that he was initially unsure about how the romance would work, but grew an understanding after filming the scenes began.

[22] He noted that deep down his character still grieved for Chantelle, and was drawn to Sharon as the two women shared several traits which got him to "take his armour down".

[24] After Kheerat's arrest was aired in November 2022, it was confirmed that Deol had left the role, with a spokesperson for the show wishing him the best for his future work.

[25] In July 2024, Deol opined that he missed playing Kheerat, who he deemed a "fantastic character", but had to leave the show to pursue other projects.

[35] After the ship received "overwhelming fan support", Deol expressed joy to Digital Spy about how a "you have British turban wearing Sikh man in love with a mixed race woman and that's completely okay", adding that he was "moved" by people who were encouraging a relationship between the characters and hoped it would help pave the way for more representation on television.

[37] Following the episode that aired on 15 February 2021, where it is revealed that Kheerat had been spooking Gray, Grace Morris of What's On TV reported viewers being "ecstatic" by the revenge.

[39] Laura Denby of Radio Times called the unannounced departure a "shock", and hoped that the character wasn't gone from the soap for good as he had become "a popular mainstay" and his exit had been deemed a "huge injustice".

[40] Matt Spivey of MyLondon called Kheerat a "firm fan favourite", despite acknowledging the character's various "rough patches".

[41] His colleague, Amber-Louise Large, noted that viewers were unhappy with Kheerat's ending, with many calling his exit storyline "far fetched" and "terrible".

[43] Looking back at his time on the soap, Deol noted Kheerat "meant so much" to both the fans and Punjabi Sikh people.
