Efforts by landlords to engage their tenants in the Welsh Quality Housing Standard (WQHS) is patchy, according to John Drysdale of the Tenant Participation Advisory Service (TPAS) Cymru.
Whilst giving evidence to the Public Accounts Committee on 6 March 2012, he warned that there is "a huge iceberg of people" who are not involved or aware of what's going on.
The WHQS sets a minimum standard for homes, with certain requirements at its core that are more challenging than similar schemes in other parts of the United Kingdom.
In many cases landlords are required to install new bathrooms and kitchens to reach the standard.
Committee members were discussing the standard in light of a the Wales Audit Office's report published in January 2012, on standards in social housing.
The report looked at the progress made in delivering the Welsh Quality Housing Standard (WQHS), which was introduced by the Welsh government in 2002 in order to help improve social housing standards.
Despite making significant improvements, the original aim that all social housing would meet the WHQS by 2012 will not be met for some considerable time, according to the report.
