Borough Market has written off the rents owed by tenants for the 11 days they were closed following the terror attack on 3 June.
The charity which runs the market said it is trying to help traders work through financial difficulties which resulted from the closure, The Sunday Times reported.
The market is open today for a special extra day of trading, despite usually being closed on Sundays. It will also open Sunday 25 June, as traders try to make up for lost business and other closure costs.
The market reopened on Wednesday for the first time since terrorists killed 8 people earlier this month.
