The lender is reopening its entire shared equity and ownership range to homemovers and not just first-time buyers.
In June Halifax restricted lending using the scheme to first-time buyers, which it said was a temporary measure reflecting its share of over 50% of the market.
In August the lender capped maximum loan sizes to £150,000, but these are also being increased to £250,000.
A Lloyds Banking Group spokesperson, said: “This was a prudent, short-term change to ensure we did not take a disproportionate share of the market, while continuing to support first-time buyers who have limited options to get onto the ladder.
“We remain committed to supporting the affordable housing sector and new build market, and will continue to review and make changes when appropriate.”
