Members of the two bodies voted in favour of a merger to create the National Residential Landlords Association (NRLA) representing 80,000 landlords in September 2019.
Ben Beadle (pictured), former director of operations at housing group Touchstone, joined the merging operations to serve as chief executive of the new entity.
A statement from the RLA said: “NRLA remains on plan to merge. Despite a target of January being set at the time of the members’ vote last September, this was ambitious and technicalities have put dates back by a few weeks.
Beadle added: “Members of both associations continue to receive full services. Amalgamation of resources is going well and the new organisation will launch within a few weeks.”
The former chief executives Richard Lambert at NLA and Andrew Dixon at RLA departed at the end of 2019.
