The value of UK mortgage arrears jumped by almost a third in April to June 2023 compared with the same period last year, according to the Bank of England (BoE).
Outstanding mortgage debt is now £16.9bn, the highest since 2016, it said.
Mortgage costs have risen for millions as the Bank has repeatedly hiked interest rates to slow soaring prices.
Some experts warn defaults will rise, but others say the number unable to repay remains relatively low.
According to the BoE, in April-June 16% of mortgages in arrears were new cases, which it said ‘was little changed compared to the previous quarter’.
It added that the proportion of mortgages in arrears was the highest since 2018.
