This comes as £35bn worth of mortgages are due to mature later on this year.
Yorkshire Building Society has introduced a 2-year fixed rate mortgage at 1.19% with a £995 fee and £500 cashback.
Meanwhile the society has launched a remortgage 5-year fix at 2.39% to 75% LTV with no product fee and £250 cashback.
These additions include free standard valuation and free legal service.
Charles Mungroo, mortgage manager at Yorkshire Building Society, said: "We hope by reducing rates on mortgages and adding attractive additional features to selected mortgages it will ease the cost of remortgaging for borrowers and give them a helping hand at what can become an expensive time.”
This comes as more than £35bn worth of mortgages are due to mature in September and October.
