The incentive is available on 75-90% LTV 2-year deals and 85-90% LTV 7-year deals.
Stephen Noakes, mortgage director at Halifax, said the bank wants to “make things easier” for its customers.
He said: “£1,000 should go some way to covering unexpected costs like buying necessary furniture and personalising the home or even going on holiday to unwind when the whole experience is over.”
For homebuyers who have a Halifax current account an additional £150 cash back is available.
The offer will be available to first-time buyers who take out a mortgage with Halifax between 23 October and 6 December 2012, with £1,000 paid to the customer via their conveyancer once the purchase has been completed.
Halifax has also improved rates across its mortgage range by up to 0.15%.
