Concerns have been voiced that as a result of the fees ban, more landlords will decide to self-manage when they have limited experience and knowledge.
Members of the Fair Fees Forum, which met last week, also said that if agents are not allowed to charge for referencing, then this could lead to the exclusion of vulnerable tenants and those on benefits.
The Forum called for a coherent framework to the regulation of the private rented sector, including registration of all letting agents and effective enforcement.
Attendees at the meeting included Belvoir, Chestertons, Countrywide, Hamptons, Hunters, Ryder & Dutton, Savills and Winkworth.
Also in attendance were trade bodies, redress schemes and tenancy deposit schemes, while the Department for Communities and Local Government was present in listening mode.
The Forum will meet again in July after the consultation on the fees ban has closed.
