Richard Lane, director of external affairs at StepChange, said: "Today’s data from the bank shows that, in July, consumer borrowing was equalled by repayment of debt.
"In aggregate this perhaps paints a reasonably reassuring, if cautious, picture of the state of household finances.
"However, it masks the fact that, for some people, borrowing isn’t a discretionary activity, it’s the only way they can afford to put food on the table and keep the lights on.
“Among our own clients, we continue to see that many of those coming to us are from over-represented groups that have been negatively affected by the pandemic.
"We remain concerned that as support measures come to a close in the Autumn, financial pressures remain very real for many.
"The risk is of a two-speed recovery that leaves behind those who have been hardest hit – we strongly urge government to pay attention to their needs.”
