Nearly a third (31%) of customers used at least some of the cash raised to pay off unsecured debts such as credit cards or loans in quarter one 2015, up from a quarter (26%) in 2014.
Over the same period the number of customers using funds to pay off mortgage debts also rose from 21% to 23%.
Equity release is most commonly used for home and garden improvements, with three in five (61%) releasing the funds for that purpose. A quarter (26%) also use the money to spend on family and friends.
Dean Mirfin, technical director at Key Retirement, said: “Debt in retirement is a growing issue with large numbers of customers using money to clear mortgages as well as credit card debts and loans.
“That highlights a real need for lenders - including equity release providers - to develop solutions to help.”
Typical equity release customers released £66,730 in the first quarter of 2015, up from £61,200 in the one before, while in London the average was nearly £130,000.
