Fire safety isn’t a theoretical concern, it’s a real risk. In the past year alone, England recorded 38,189 building fires, accounting for nearly two-thirds of all major fire incidents. While high-rise fires have declined slightly, commercial and industrial buildings remain vulnerable, making fire-resistant design essential. Steel may not burn, but extreme heat can compromise its integrity. That’s why compliance with 2025 fire regulations isn’t about ticking boxes, it’s about protecting lives, assets, and businesses.
Here are five key fire safety practices for steel buildings in 2025 and beyond.
1. Understanding the New Fire Regulations
Fire safety laws are evolving. The 2025 update to Approved Document B consolidates previous amendments and introduces stricter compliance measures. One of the biggest changes is the shift from BS 476 fire testing to BS EN 13501, aligning UK standards with European norms. This directly affects fire resistance classifications for materials used in steel construction.
What does this mean for developers and contractors? You’ll need to ensure that all materials and fireproofing strategies meet the updated testing standards. Falling behind on compliance isn’t an option. Adapt now to avoid costly redesigns later.
2. Investing in Intumescent Coatings
Steel doesn’t burn, but under intense heat, it loses structural integrity. That’s where intumescent coatings come in. These fire-resistant paints expand when exposed to high temperatures, forming an insulating barrier that slows heat transfer and extends a building’s fire resistance.
Delaying structural failure by even a few minutes can be the difference between safe evacuation and catastrophe making intumescent coatings a critical investment in fire safety.
BS EN 13501 has become the established standard and is designed to reflect the latest advancements in fire protection technology whilst addressing the growing demands for safer buildings.
3. Prioritising Passive Fire Protection Measures
Fire-rated walls, doors, and ceilings compartmentalise buildings, containing fire and smoke while allowing safe evacuation. Fire stopping systems (sealants, barriers, and fire-resistant ductwork) help maintain compartmentalisation.
Without these measures, fire can spread rapidly, turning a small incident into a full-scale disaster. The key? Design with fire protection in mind from day one, ensuring escape routes remain secure and structural integrity is maintained.
4. Adapting to Environmental Changes in Fire Safety
Sustainability is changing the fire safety landscape. A major shift in 2025 is the UK’s ban on AFFF fire extinguishers, a move aimed at reducing environmental harm. Steel buildings must now incorporate alternative fire suppression systems that meet both safety and environmental standards.
Sustainability and fire safety don’t have to be at odds. Developers should also explore eco-friendly fire-resistant materials that support both safety and carbon reduction goals. By choosing the right materials and suppression methods, you can future-proof your buildings against both regulatory and environmental challenges.
5. Implementing Personal Emergency Evacuation Plans (PEEPs)
In 2025, Personal Emergency Evacuation Plans (PEEPs) will become mandatory for high-rise and high-risk buildings. This means tailored evacuation strategies must be in place for vulnerable individuals and safety is prioritised for everyone.
For steel-framed commercial and residential buildings, this translates to accessible escape routes, clearly marked exits, and fire-safe refuge areas.
Staying Ahead of Fire Safety Challenges
The future of fire safety in steel buildings is being shaped by regulation, innovation, and sustainability. As fire safety standards continue to evolve, Carnegie Steel Buildings is committed to staying ahead of these changes, helping clients navigate the latest compliance requirements while delivering resilient, fire-safe structures.
