During the initial trial period, the product rates will start from 7.89 per cent to 10.69 per cent and is available up to 90 per cent LTV.
If successful, the product could well be introduced as part of Future Mortgages' core product range.
Ian Warrilow, head of secured lending at Future Mortgages, said the scheme was a product of discussions with the firm's key partners:
"Our research has shown that in current market conditions customers value longer term security and the opportunity to accurately budget their financial commitments," he explained. "We therefore want to help our key partners with a product range that can meet the financial needs of their clients.
"We have offered this new product to a limited panel of brokers as a way of recognising our key partners since the launch of our web based decision system in July 2007."
