The mortgages are available to purchase and remortgage customers, and have interest rates of 5.79%, with a £1,499 fee, or 5.99%, with a £999 fee.
The two deals are available on a repayment basis and can only be accessed by Openwork appointed representatives.
Purchase deals offer a refunded valuation and remortgage deals come with a free valuation.
Paul Shearman, mortgage, protection and general insurance proposition director at Openwork, said: “These products from Halifax offer a competitive rate for borrowers with a small deposit and we are pleased to be able to offer these deals on an exclusive basis, enabling our advisers to help kick start the first- and second-time buyer markets.”
