Halifax is giving first-time buyers, homemovers and remortgage customers £750 cashback on qualifying mortgages.
Free basic legal fees and standard valuation costs will also be paid by the bank to remortgage customers.
Eligible borrowers will also be supported through the mortgage process by a dedicated mortgage adviser.
Richard Washington, mortgages director at Halifax, said: “Buying a home is one of the biggest financial commitments of our lives – whether it’s a first property or another step on the housing ladder.
“Our latest cashback offer supports customers at this expensive time and helps those remortgaging with any unexpected costs.”
