The group will open a 50-cover restaurant on Buckingham Palace Road in Victoria on 14 October, its fifth in the capital.
The new restaurant will serve a menu of meat-free dishes including The Big Stack; Filet-No-Fish; and the Neat Dog as well as its bread-free burger bowls alongside items such as Chick'n bites, and taer tots.
"We are thrilled to launch a new site in Victoria, with the hope to encourage both plant-based diners and meat eaters alike to visit and sample our delicious vegan burgers and sides, whilst having an actively positive impact on the planet," says co-founder Zack Bishti.
The company announced it was looking at Victoria back in August, with sites in the capital also being lined up in Westfield Stratford, Canary Wharf, Bishopsgate, Kings Road, and Ealing.
Neat Burger is tipped for rapid expansion in the UK in the coming years with it expected to have a portfolio of around 20 UK restaurants by mid next year.
It recently signed a partnership with dark kitchen operator Reef Technology with plans to expand its dark kitchen presence across the UK. The company is also looking to grow internationally and has signed franchise deals in Italy, the Gulf, and America.
