A new lender has been granted a licence by UK financial regulators to offer mortgages with fixed rates of up to 50 years.
Perenna is initially planning to provide home loans that lock in rates for 30 years, before rolling out products with even longer terms.
It could offer rates of 4% to 4.5% on the 30 to 50-year loans, although this would be affected by gilt yields at the time of launch.
