Water Mist Systems in UK Buildings: An Alternative to Traditional Sprinklers

Water mist systems use less water and cause less damage than sprinklers. We examine their applications and UK approval status.. Water Mist Systems How They Work Water mist systems use very fine droplets (typically <200 microns) at high pressure. The fine mist absorbs heat, displaces oxygen, and blocks radiant heat — suppressing fire with 80 90% less water than sprinklers. UK Applications Heritage buildings (minimal water damage) Residential retrofits (smaller pipe sizes) Commercial kitchens Machinery spaces Cable tunnels Standards BS 8458 — Fixed fire protection systems: residential and domestic water mist BS 8489 — Fixed fire protection systems: industrial and commercial water mist Third party certification essential (LPCB, FM, VdS) For water mist system design, contact us.
