Figures from the lender show that almost one in ten customers who have both savings and borrowings with the bank now pay no interest on all their borrowings.
Ian Jeffery, sales director at IF, said: "I believe our transparent, competitive pricing and our fairer principle of offsetting balances for interest purposes, will help us to continue to grow strongly in the year ahead. Our plans for the intermediary sector are well advanced and 2002 will see us adding real value to our relationships with this important sector of the market."
