United Biscuits' Carlisle factory remains closed after it was affected by Storm Desmond.
In a statement released on the firm’s website, spokespeople for UB said the local water levels have subsided and site access has been regained by specialist teams.
Officials are currently conducting an initial impact assessment and coordinating the reinstatement of temporary power supplies.
The statement said that after the assessment, UB would be able to give further update: “We will be able to update further on a planned timetable for the clean-up operation, subsequent resumption of production and fulfilment of orders.
“The company greatly appreciates the offers of help from the local employees, suppliers and their colleagues across United Biscuits to resume business as usual.
“Our thoughts remain with the thousands of people across Cumbria and Lancashire who have been impacted by the floods.”
Carlisle is one of the company’s largest employee catchment areas and more than 600 people work at the site.
In 2005 UB was handed a £1m government grant to secure its repair after similar floods caused millions of pounds of damage.
Production of biscuits were relocated to other factories across Britain during the lengthy clean-up process.
The army has been drafted in to support those affected. David Cameron has called an emergency Cobra meeting to deal with the situation.
