The remortgage products, which have no booking fee, will be available through all of its key accounts. Deals include a two-year 60% loan-to-value fixed rate at 2.44% and a five-year 70% LTV fixed-rate at 2.99%.
Meanwhile, the lender has cut rates on its Help to Buy products by five basis points. A two-year fixed rate or tracker will be offered from next week at 3.24% and five-year fixed rate products at 3.44%.
The cuts come a month after Halifax reduced the rate on its Help to Buy two-year fixed rate offering to 3.34%.
Santander for Intermediaries managing director Miguel Sard said: “We are pleased to support intermediaries and their clients with further rate reductions across our range.
“In addition, we have launched a new range of market leading zero fee remortgage products, which are available exclusively through our key accounts partners.”
