The British Bankers’ Association says banks will sympathetically and sensitively consider the problems of each business.
Extra financial support will be available such as short to medium term finance arrangements for repairs and to replace stock and repayment holidays until insurance claims are settled.
Many bank branches have also been affected by the riots. Even in these areas banks are doing their best to make sure that all customers can get the banking services they need.
BBA chief executive Angela Knight said: "These riots are appalling. It seems that the majority of businesses affected are small.
“We hope that as many as possible will reopen and the banks are putting in place arrangements to help. Businesses must contact their insurance company, but at the same time we know that claims take time to process and we stand ready to help."
