The deals are available through selected house builders only and via a limited distribution of brokers.
A Halifax spokeswoman said: “This move recognises changes in the new build market and will allow us to support those unable to meet larger deposit requirements.”
The products will be available for new build houses built by Barratts, Persimmon Homes and Taylor Wimpey and their subsidiaries.
“These builders have been selected following a very thorough review process,” added the spokeswoman. “However we will assess the list of participating builders on an ongoing basis.”
The maximum LTV will remain at 80% for new build flats and all new build houses not through one of the named builders. It will remain at 65% for buy-to-let lending.
Halifax did not confirm which brokers were able to access the deal.
