Octink has said it may have to move because of the difficulties the closure of Church Street in Isleworth is causing them.
Hounslow Council closed the road to through traffic to stop it being used as a “rat run”. However, Octink, who employ 120 people in nearby Brentford say they will be forced to relocate if the closure continues.
Chief executive Will Tyler told Getwestlondon he would be instructing agents early in 2016 to begin a search for new premises unless the road was reopened.
He cited additional half-hour journey times for delivery vans and for staff travelling to work due to traffic hold ups caused by the closure.
