Mr. Eoin O'Dowd:

I think I can answer that. The provisions for sprinklers were originally introduced in an amendment to Technical Guidance Document B in 2020. The particulars for the systems, given they are an essential life safety system, require certainty in use and performance. For that reason, there is a provision within the then technical guidance document and in the 2024 version that there is a tank or a dedicated supply and that there is redundancy in pumps and facilities provided to ensure there is a continuity of service. The provision for the building regulations are separate, with provision of water in buildings generally. They are designed to ensure that reliability in use of an essential system.
