Bakkavor is expected to close the former Geest headquarters at Midgate in Peterborough.
The Icelandic company took Geest over last year and recently gave the long-established UK business the Bakkavor name, removing one of the iconic names of the trade.
Now all the central functions at Peterborough are being passed down to the individual businesses making them stand-alone divisions within Bakkavor.
Although Bakkavor has as yet not confirmed details, staff at Midgate are reported to be on a consultation period and an insider told freshinfo they are likely to be allowed to go after Christmas.
