TSB has launched a 5-year fixed remortgage product.
Available up to 60% LTV, the mortgage is priced at 1.49% and comes with a £1,495 product fee.
There is a choice of free legals or £300 cashback.
Nick Smith, head of mortgages at TSB, said: “The mortgage market is currently very competitive as borrowers come off existing fixed rate deals.
“Due to an increase in demand for longer-term fixed rate products, particularly at the lower LTV end of the spectrum, we have introduced this new 5-year remortgage deal.
“We expect it to be very popular.”
The lender has also increased rates for 5-year fixed rate mortgages for purchases.
There is a 2.49% deal which comes with a £999 product fee and a 2.54% mortgage which has no fee.
Both mortgages are available from 85% to 90% LTV.
