The new product will offer the lowest rate for a five-year fixed deal ever offered by the society. It is available from Friday 23rd July, with a £995 fee.
For those looking for longer-term security, the society is also offering a ten-year fixed rate deal at 4.99% for those with a 75% deposit, with a fee of only £495.
Tom Girling, product manager for mortgages, said: "Although we are currently in a low base rate environment, it is inevitable that rates will rise in the next few years. Both our five and ten-year deals offer great value and piece of mind over the medium and longer-term - reducing the risk of any future interest rate rises.
"The new five-year product offers the lowest rate for a five-year fixed deal ever offered by the Yorkshire and is a great option for borrowers wanting a fantastic rate coupled with longer-term security when it comes to their mortgage payments - offering one less thing to worry about in these uncertain times."
