Halifax is offering £250 cashback for remortgaging from another mortgage provider.
Applications on qualifying mortgages must be made between 27 March and 7 May 2017.
Eligible borrowers can also have their legal fees and property assessment covered, and will have the support of a dedicated mortgage adviser.
Richard Washington, mortgages director at Halifax, said: “A mortgage is often our greatest financial commitment, so taking the right opportunity to remortgage can be an effective way of streamlining what’s often a household’s biggest outgoing.
“Moving to a new deal can not only help to make monthly payments more manageable, but our latest £250 cashback offer also helps to make remortgagers better off, providing a boost to bank accounts.”
