In September 2016, Kout Food Group hired a property agent to carry out a strategic review of the 13 Maison Blanc locations and production facility.[6] In December 2016, there were rumours that rival, Patisserie Valerie, would purchase the chain, but with Kout Food Group retaining the brand name.[7]
In March 2017, the chain was closed by Kout Food Group as they began to withdraw from the UK market, with all locations closed down.[8]
In July 2017, it was announced that Patisserie Valerie would move into four former Maison Blanc locations.[9]
In February 2019, Maison Blanc's former production facility was sold to Joe & Seph's. The office space above had served as the UK headquarters for Kout Food Group.[10]
