Property website Zoopla has announced it will no longer allow adverts which rule out renters who receive benefits.
The property portal has said that from April it will amend its member terms and conditions to prohibit the inclusion of the term "no DSS".
It will also remove the reference from listings uploaded to its website and from search fields in its cloud-based software products.

Zoopla said the new measures are in support of recommendations from the National Landlords Association and the Residential Landlords Association.
Previous analysis of 86,000 letting agent adverts on Zoopla by the National Housing Federation and charity Shelter found that 8,710 of the postings said "no DSS" or "no housing benefit".
Figures released by the Ministry of Housing, Communities and Local Government suggest that half of landlords would not be willing to let a property to tenants who receive housing benefit.
Charlie Bryant, managing director of Zoopla, said: "All tenants who are looking to rent a property deserve the chance to be fully assessed for their suitability and matched to a home that suits both their and the landlord's circumstances."
