The intermediary lender will also reduce rates by up to 0.25% across a selection of its 80% LTV products.
The new rates include a two-year fix for homebuyers at 4.70%, which also offers a free basic valuation and £250 cash back and a two-year fix for remortgagers at 4.75%, which also comes with a valuation and either basic legal costs or £250 cash back.
