Question

To ask the hon. Member for Blaenau Gwent and Rhymney, representing the House of Commons Commission, for what reason some of the toilets at Block T-3 in the Parliamentary estate have been sealed since January 2025.

The toilets in T-block are closed due to the presence of Reinforced Autoclaved Aerated Concrete (RAAC), following guidance from the Institution of Structural Engineers published in 2023 and surveys carried out by structural engineers in 2024.

A further programme of investigation, longer-term mitigation and limited replacement (where possible and practical) continues to be developed by Strategic Estates. This requires thorough and potentially disruptive surveys that are carried out around the business of the House (for example, during recess). The investigations and surveys will provide a comprehensive assessment of the issues and works required to reopen the toilets, and if it is feasible or practical to do so.

The next phase of the programme is currently expected to begin by Summer recess, starting with surveys and investigations; the surveys could continue until the end of Conference recess. The project is envisaged to run to the end of 2027, due to the complexity of the work involved.
