Homemovers who want access to the shared equity and shared ownership deals must now arrange these through an in-branch adviser.
Only first-time buyers will be able to access products such as the Help to Buy equity loan through brokers.
A spokesperson for Halifax said: “Halifax has recently taken the decision to temporarily offer shared equity and shared ownership mortgages to first-time buyers only through its intermediary network.
“We remain fully committed to supporting first time buyers, and the affordable housing sector. This prudent, short term change reflects that Halifax currently holds a circa 50% share of this market.”
The Help to Buy mortgage indemnity guarantee scheme remains available through mortgage brokers.
