"Borough Market has adapted to meet the needs of Londoners for hundreds of years and continues to do so," said managing director Keith Davis.
"Opening the market for Wednesday trading will make available a world-class, ingredient-led market four days a week and allows us to respond to the needs of our customers in 21st-century London, whilst our lunch market on Mondays and Tuesdays will continue to provide quality lunches for those working and living in SE1."
From Monday 2 September onwards Borough Market's hours will be:
• Monday & Tuesday: 10am-5pm (lunch market)
• Wednesday & Thursday 10am-5pm (full market)
• Friday: 10am-6pm
