Making Fire Suppression Simple: BS 9251 vs BS 8458
JUN 10, 2025 | 2 minute read minutes read
Not all automatic suppression systems for domestic or residential occupancy are the same. We're launching an educational series that cuts through the complexity. Using simple language and straightforward comparisons, we'll explore the differences between BS 9251:2021 (Sprinklers) and BS 8458:2015 (Watermist).
Why? Because quantity surveyors, architects, and building professionals shouldn't need a PhD to understand their options.
What we'll cover:
• How each system works
• Real installation requirements and constraints
• Testing and maintenance—what's actually involved
• True cost comparisons—installation through life-cycle • Which system suits which building type
Our promise:No jargon. No bias. No sales pitch.
Just clear, factual information that helps you make informed decisions. We'll present both standards objectively, highlighting the practical differences that matter to your projects. Whether you're specifying for a residential tower, student accommodation, or care home, this series will give you the knowledge to choose with confidence.
Follow along as we demystify fire suppression standards—one simple comparison at a time.
