The lender has made the move on a temporary basis as it currently holds around 50% of this segment of the market.
Its change will affect Help to Buy equity loan scheme and all other shared equity and shared ownership products.
A Lloyds Banking Group spokesperson said: “We have taken the decision to temporarily cap shared equity and shared ownership lending to £150,000.
“This is a prudent, short-term change that reflects the fact that we currently hold around a 50% share of this market and is a further step to focus our activity on supporting 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, recently extending our Help to Buy mortgage guarantee scheme to allow applications for those with a 5% deposit on new build properties.”
