Regulator publishes update on reinforced autoclaved aerated concrete (RAAC) in social housing

November 13, 2024

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

Following further updates from landlords, 145 social landlords have now confirmed that there is no RAAC present in their tenants’ homes.  Sixteen landlords have identified the presence of RAAC in some of the homes they provide to tenants, with 2445 homes affected. 

The sixteen 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
  • City of Edinburgh Council
  • Clackmannanshire Council
  • Dundee City Council
  • Link Group Ltd
  • Linstone Housing Association Ltd
  • North Lanarkshire Council
  • River Clyde Homes
  • Sanctuary Scotland Housing Association Ltd
  • South Lanarkshire Council
  • Stirling Council
  • Viewpoint Housing Association Ltd
  • West Lothian Council

Four landlords continue to investigate whether RAAC is present in any of their homes. These are:

  • Bridgewater Housing Association Ltd
  • Irvine Housing Association Ltd
  • North Ayrshire Council
  • Perth and Kinross Council

The number of homes currently under investigation is 667.  

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 management plans for the affected homes. A further four landlords are yet to fully complete their investigations into the presence of RAAC in some of their homes and we are engaging with them to get assurance about the plans they have in place to assess RAAC and timescales for completion.  We will continue to monitor landlords’ management of RAAC through our engagement with landlords.”

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