The Scottish Housing Regulator has published updated information on the presence of reinforced autoclaved aerated concrete (RAAC) in social housing.

Earlier this month the regulator asked social landlords to provide an update where they were continuing to investigate the presence of RAAC in their homes.

The updated position shows that 13 landlords have now identified the presence of RAAC in some of the homes, with 1,994 homes affected. 125 landlords have confirmed that there is no RAAC present in their homes, and 27 continue to investigate whether RAAC is present. The number of homes currently under investigation is 8,311.

The 13 landlords that have identified the presence of RAAC in some of their homes are:

Aberdeen City Council

Almond Housing Association Ltd

Angus Council

Bield Housing & Care

The City of Edinburgh Council

Clackmannanshire Council

Dundee City Council

North Lanarkshire Council

Sanctuary Scotland Housing Association Ltd

South Lanarkshire Council

Stirling Council

Viewpoint Housing Association Ltd

West Lothian Council

Nicola Harcus, Assistant Director with the regulator, said: “We have engaged with the landlords that have identified RAAC in their homes and have assurance that they have appropriate management plans for the affected homes.  We will continue to update the information we have on the presence of RAAC in social housing as landlords complete their outstanding investigations.”

RAAC is a lightweight structural construction material used between the 1950s and 1990s in the floors, walls and roofs of some buildings in Scotland, including some residential properties.  It is no longer used in buildings in Scotland.

More information about RAAC and the risks associated with its use is available on the website of the Institution of Structural Engineers.
