The products, which are being unveiled through its distributor packagers, include a 3-year fix at 3.99% and outside London and the South East a 3-year discounted rate (1.5% from SVR) at 3.49%.
The two products are offered to 75% loan to value or loans between £500,001 and £1m on terms ranging from 5 years to 35-years.
Jeremy Wood, chief executive of Dudley Building Society, said: “Last year much of our resource was employed in bedding in new processes and the new IT system, designed specifically to build our capability in the intermediary market.
“Having successfully completed that transition, this year we are focussing on developing our product range while continuing to improve our service to the intermediary community.
“These new products demonstrate our commitment to provide products that answer the needs of our introducers and their customers.”
The society has also launched another discounted rate product at 3.19% for 3-years for purchase and remortgage to 80% LTV for loans between £25,000 and £500,000.
Customers can make overpayments of up to 10% for the first three years.
