Opening in Chelsea, it will be the third dark kitchen to launch under the brand since it was established back in June.
Pearce has previously said he has aspirations of Clean Kitchen Club becoming the 'fastest growing plant-based delivery-kitchen brand in the UK', and has plans to also open sites in Wandsworth, Tumbridge Wells, Manchester, Edinburgh and Bournemouth in the coming weeks.
Clean Kitchen Club currently operates two delivery-only sites in Brighton, with the group saying the concept has proven to be a 'huge success' since it launched eight weeks ago.
Pearce has launched the business in partnership with his childhood friend Abe Garman, serving a '100% plant-based burger menu'.
Options include the 'Clean' burger, featuring a homemade vegan patty, lettuce, tomato, gherkin, vegan cheese, vegan mayo and ketchup; the buffalo burger, with a THIS isn’t chicken patty, buffalo sauce, vegan cheese, dill, vegan mayo, lettuce and tomato; and loaded fries topped with sriracha mayo, crushed peanuts, toasted sesame, crispy onions, and melted vegan cheese.
“The focus from the get go has been to bring people delicious, guilt-free food," says Pearce.
"We’ve made sure we’ve sourced the freshest ingredients we can to create some truly special dishes and we’re happy to report everyone seems to be loving them, no matter whether they follow a plant-based diet or not.
“We’ve felt so blessed that the local Brighton community has really got behind us and we’re aiming to become the UK’s fastest growing plant-based brand, opening sites in every major city.
"Chelsea will be our first London site but by no means our last."
The UK's plant-based burger market has snowballed in the last year or so, particularly in the capital.
Earlier this year, Halo Burger opened its first bricks and mortar site in London's Shoreditch, having previously operated solely out of a shipping container kitchen in POP Brixton.
At the time founder Ross Forder said his plan was to eventually expand the concept across the UK.
Meanwhile, the Lewis Hamilton-backed Neat Burger made its debut in Mayfair last September, with its founders saying at the time that they hope to establish more than 100 sites internationally in the next five years
