Franco Di Pietro, head of intermediary mortgages at Newcastle BS (pictured), said that it was “ready to respond to changing market trends” to meet the diverse needs of brokers and clients.
He explained: “In the current rate environment and with the rising cost of living, our 10-year fixed rate offers brokers and their clients an option for those who may want or need to plan ahead and value the payment stability and peace of mind that an extended fixed rate provides.”
A PR spokesperson said that this the only 10-year fixed rate in the mutual’s range and it is the first it has launched in a few years. They added that Newcastle BS had been “seeing increased consumer demand for longer-term fixes in a rising rate environment”.
According to Moneyfacts, the number of 10-year fixed rates on the market has fluctuated over the past year, going from 114 in April last year to a peak of 180 in February this year. It has since then steadily fallen to around 115 to date.
