Halifax is offering £750 cashback on qualifying mortgages to first-time buyers, homemovers and remortgage customers.
The lender’s broker-only arm, Halifax Intermediaries, offers £500 cashback to similar customers.
Halifax will pay basic legal and valuation costs for remortgagors.
Halifax mortgages director Richard Washington says: “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.”
The cashback will be paid automatically on completion and is available from 2 October to 2 January 2018.
