Belu
Welsh natural mineral water from a borehole at Churchstoke, Montgomeryshire, listed on Defra’s register as “Belu”. Montgomery Waters, a family-owned bottler with several registered sources at Churchstoke, bottles it at source; Belu named the partnership on its site in May 2026. Belu Water Ltd is owned by The Belu Foundation, a charity that has held 75% or more of the shares since October 2024 (Companies House). The company says it gives all net profits to WaterAid. Two other Belu products are not this water: the 330 ml cans hold spring water filled at Wenlock Spring in Shropshire, and the “filtration” range is filtered mains water.
