Oldrids & Downtown will reopen two stores in Lincolnshire on June 15.
Downtown Superstores in Grantham and Boston will be allowed to return trading alongside the rest of the retail sector.
Downtown’s garden centres have been open since May 13, but the home and fashion section of the stores are now being reopened.
In a statement published on Facebook, the company said: “We have really missed seeing our wonderful customers and never, in our 216 year history, have we been away from you for so long.
“We are very excited about the 15th. We are confident that during these difficult times our cautious and considered approach has protected our people, our customers and our business.”
The 2 metre markings will be placed on the floors of the shops, as well as having perspex screens at tills and regular cleaning of key touch points.
