Reinforced autoclaved aerated concrete (RAAC) is a lightweight material that was used between the 1950s and 1990s, predominantly in the construction of flat roof sections but also in floors and walls.  This material has a limited lifespan of around 30 years and has been found to be susceptible to structural failure particularly when exposed to moisture. RAAC panels were often coated with bitumen or similar moisture retardant substances but the concrete beneath this coating layer can still be compromised and the Health and Safety Executive have gone on record that RAAC which has been in situ beyond its lifespan may "collapse with little or no notice".

The Scottish Housing Regulator continues to monitor responses from RSLs who have stock which may be impacted by the existence of RAAC. Some local authorities too have identified they have stock which include RAAC. Private owners, particularly those who acquired their properties directly as part of the former Right to Buy scheme, or who acquired such units later as part of an arms length deal think that the local authority or RSL who were involved in the initial sale should assist them in addressing any RAAC issues they face. Whilst local authorities and RSLs recognise and to some extent share the problems individual homeowners are facing, RSLs should explain to homeowners that they must seek their own advice and surveys to determine how best they can address any resultant structural problems in their individual properties. The Scottish Government have not confirmed any additional funding will be made available to meet RAAC costs incurred by any party affected and this includes RSLs.

We are aware that West Lothian Council met with homeowners earlier in the year and shared the concerns owners expressed with the Scottish Government.  Many of the concerns identified are faced by RSLs including;

• the need for affordable insurance to continue to be offered for units affected by RAAC, and
• that lenders will continue to offer loans to enable those who want to acquire RAAC affected units can do so.

These are issues which must be addressed at national level by the intervention, if required, by the Scottish Government. We will continue to monitor and report on information relative to this topic when available.
