The SHR had been assessing the quality of social housing in the country, requiring landlords to carry out checks on these properties.

16 landlords have identified the presence of RAAC in some of their properties, with 2,445 homes affected.

These included Aberdeen City Council, Dundee City Council, City of Edinburgh Council and River Clyde Homes.

Four landlords - Bridgewater Housing Association, Irvine Housing Association, North Ayrshire Council and Perth and Kinross Council - are continuing to investigate the presence of RAAC.

This leaves 667 homes under investigation.

Elsewhere, 145 social landlords had confirmed there was no presence of RAAC in tenants’ homes.

Nicola Harcus, assistant director at the SHR, said the authority was coordinating with the four landlords still investigating to ensure they had plans in place and timescales for completion.

“We will continue to monitor landlords’ management of RAAC through our engagement with landlords,” added Nicola.

RAAC is a type of porous, weaker concrete that is prone to sudden collapse. It was widely used in schools and other public buildings between the 1950s and 1990s.

It entered prominence in 2018 when a school roof collapsed in Kent. The UK government has since been removing this from schools and other public buildings.
