This will mean its One Mortgage, where the interest rate is fixed for the life of the mortgage, will have rates starting from 3.4pc, down from 3.8pc.
It is also reducing its three-year rate, down 0.1 of a percentage point to 3.6pc for those borrowing 80pc or less of the value of the home.
Its four-year fixed rate, which is its most popular mortgage product, will see its rate go from 3.6pc to 3.4pc.
The new rates are effective from next Thursday, November 7, with the cash-back incentive coming in from the start of next year.
