Why is the South Harrow Branch closing. Before the mobile, internet and telephone banking. The only way to do meet your banking needs was to come into branch. But today with debit and credit card payments, bank transfers, mobile, internet and telephone banking less and less people visit the branch. Barclays say that "less than 10 customers use the branch regularly as the only way they do their banking and 44% of this branches customers have used nearly branches in the last 12 months." Please see the Barclays web page on the closure of this branch in the link below for more information.
