RAAC is a reinforced form of lightweight concrete mainly used in flat roofs but also in some floor and wall panel construction in the UK from the mid-1950s to the mid-1990s.

For further information surrounding the use of RAAC, the Royal Institute of Chartered Surveyors and the Institute of Structural Engineers have published helpful guides and FAQs that may address your concerns and questions.


Schools

Following a survey carried out in 2021, no Angus Council school buildings were identified as containing Reinforced Autoclaved Aerated Concrete (RAAC).


Non-educational buildings

During inspections of our non-educational buildings in 2023 we identified that RAAC was used in the construction of the roof of Rosehill Resource Centre. A structural engineer conducted a full inspection of the roof and found the RAAC roof panels to be in good condition, with no cause for concern. The Centre remains open and operational as normal. Annual inspections are in place and remedial works will take place as required.


Housing

Inspections identified that RAAC was used in the construction of a very small number of council and former council properties in Angus.

Angus Council continues to engage with residents of all council owned and former council owned properties, where we are confident RAAC was used in the construction of the properties.

We would like to thank all households who have engaged with us so far. Your feedback has been essential in helping us coordinate our approach to RAAC remediation and continues to shape the support we provide.


Private tenants

If you are a private tenant and you suspect or have been made aware that RAAC could have been used in the construction of your property, you should speak with your landlord in the first instance to discuss your concerns.


Private owners and landlords

If you are a homeowner or landlord and you suspect or have been made aware that RAAC could have been used in the construction of your property, we strongly recommend that, if you have not done so already, you have your property inspected by a suitable qualified Chartered Structural Engineer, in accordance with the guidance issued by the Institution of Structural Engineers, to determine if RAAC panels are present in the roof. The chartered Structural Engineer will be able to assess the condition of the concrete planks, whether RAAC is present, and advise you on any necessary mitigation works. We also recommend that you speak with your home insurance company for further advice.

If you are advised by a structural engineer that works should be undertaken immediately, as a private owner, it is your responsibility to ensure the works are undertaken.

If your property sits within a terrace that adjoins an Angus Council property, and a Structural Engineer has recommended alterations to your RAAC panels and roof finishes, Angus Council Housing ask that they are consulted, as the nature of these works could impact upon our adjoining roofs.

If your property adjoins and sits within a privately owned property terrace (that are all privately owned), Angus Council suggest that owners consult with all neighbours within the terrace prior to proceeding with any recommended works.

It is important to remember that any recommended works may require owners to seek Angus Council Planning and Building Standards approval before any works are undertaken.

  • RAAC Pilot Project

    Share RAAC Pilot Project on Facebook Share RAAC Pilot Project on Twitter Share RAAC Pilot Project on Linkedin Email RAAC Pilot Project link

    At a Special Council meeting on Tuesday 9 December, Councillors granted approval to begin an initial pilot project focused on council-owned housing.

    Following a tender process earlier this year, R S Hill (Joiners & Building Contractors) has been appointed as the successful contractor to carry out the pilot works. These works are scheduled to commence on 15 June 2026 and be completed by late summer 2026.

    The pilot project will be carried out on 10 Milton Street, a vacant council-owned property adjoining another empty council-owned home. This location has been selected to ensure that no privately owned properties are affected while we assess the viability of the proposed approach.

    The pilot will involve the removal of RAAC panels and the installation of a new timber-structured flat roof. The purpose of the project is to determine whether a successful connection can be achieved between the new roof structure and the existing roof finishes.

    Contractors will be on site between 8:00am and 5:00pm, Monday to Friday, throughout the duration of the works.

    If the pilot proves successful, we will look to continue with roof replacements on additional council-owned properties.

    If the pilot is not successful, we will present alternative options to the Committee.

    The property chosen for the pilot project - 10 Milton Street - is a vacant council-owned property adjoining another empty council-owned home. This location has been selected to ensure that we can test the proposed approach and find solutions to any issues that may arise. This may involve temporary pauses to the works as we find the best solutions, and a period for such occasions has been accounted for in the planned works timescale.

    This ensures that when we progress to the next phase of RAAC remedial works on the wider council owned housing stock in Milton Street, we can plan effectively to keep disruption to a minimum for all residents.

    Scaffolding required to begin works has been erected on site. The next steps of the pilot project involve the safe removal of a material containing between 1 and 4% of asbestos that is present within a thin coating applied to the RAAC panels, similar to Artex. We would like to reassure residents that the asbestos present is contained and has minimal risk if undisturbed.

    Given the very low asbestos content and its extensive use in buildings across the UK, we do not anticipate this causing a delay to the pilot project, which remains on track for completion by the end of summer 2026.
