Lambert was previously chief executive of the British Woodworking Federation. Prior to this, he worked as a policy director at the British Property Federation and as a parliamentary civil servant.
Lambert said: “I'm hugely impressed at the way in which the NLA has built itself into a respected national organisation and developed a reputation as a credible and effective representative voice for landlords letting private residential property.
“I’m looking forward to taking this even further by ensuring that the NLA continues to work for its members, while seeking a coherent policy for the private-rented sector from government.”
David Salusbury, chairman at the NLA, said: “Richard will bring a wealth of experience to the NLA. His record at major industry associations is exemplary; past achievements include leading his previous organisation through the recession, while increasing membership and improving on the service it delivers to members.
“I would like to welcome Richard to the NLA and look forward to the benefits which his experience as an industry leader will bring to the private-rented sector.”
