Notable new deals include an 80% LTV 2-year fix at 1.88%, and an 80% LTV 5-year fix at 1.92%.
Both products include a £1,495 fee and are available for remortgages only.
In addition, an 80% LTV 2-year fix at 2.05%, and an 80% LTV 5-year fix at 2.25% have been added.
The two offerings include a £495 fee, £250 cashback and a free valuation, available to homebuyers.
Furthermore, the lender has also reduced the rates on some of its mortgages in the 75% and 85% LTV ranges, and strengthened its offering on other home loans by including additional features such as cashback, free standard valuation and free legal fees.
Ben Merritt, senior mortgage manager at Yorkshire Building Society, said: “With the housing market still very much active we’ve reduced the rates on some of our mortgages to help those looking to start the New Year with a house move, or remortgage.
“As ever, we understand people’s mortgage requirements differ, so we’ve made sure we continue to offer home loans with a number of different features to best meet the varying needs borrowers have.
“This means we’ve improved both short and longer-term fixed rate mortgages, ensured some have no product fees and for others have included additional features so borrowers can choose a mortgage best suited to them.”
