John Tooth, head of business to business mortgage distribution and strategy at Clydesdale, said: “Brokers have been telling us that there is a desire for a 3-year product from applicants who want a longer fixed term but do not want to commit to a 5-year rate.
“These new products are in response to that feedback and continue our line of introducing products that there is demand for in the intermediary market.”
