Thousands of ING Direct mortgage customers face a jump in their mortgage rate from next month.
The bank will raise its standard variable rate (SVR), which most mortgages revert to after an introductory period, from 3.5% to 3.99% on 1 August.
On a typical £150,000 repayment home loan with 20 years remaining, this would push monthly costs from £870 to £908, which would work out as a £456 annual rise.
ING has 4,500 borrowers on its SVR.
The Dutch-based bank will become the latest in a long line to raise its standard rate, blaming market conditions.
- Halifax's SVR jumped for 850,000 customers from 3.5% to 3.99% in May.
