What is Structural Fire Engineering
Evidence-based fire resistance. Performance-driven design.
Design boldly and build smart.
Structural Fire Engineering (SFE) is the science of assessing how a building’s structure will behave during a fire. It goes beyond prescriptive codes to deliver performance-based solutions using advanced modelling, heat transfer analysis, and engineering judgement. SFE is essential for validating fire resistance in complex, unconventional, or existing structures — supporting safe evacuation and emergency response.

Tailored Specifications
"Working collaboratively with Kiwa we have been able to navigate through the constantly changing requirements for compliant fire safety design and have successfully implemented our own ‘best practice’ standards.”
Frequently Asked Questions
Q: Can you assess existing buildings?
A: Yes. We conduct site inspections and desktop studies to evaluate fire resistance during refurbishment or change of use.
Q: What modelling techniques do you use?
A: We use finite element analysis, CFD, and heat transfer simulations aligned with Eurocode and BS standard
Q: How does Structural Fire Engineering help me meet Building Regulations?
A: Our performance-based approach ensures compliance with UK Building Regulations and recognised standards like Eurocode and BS 7974, giving you confidence in regulatory approval.
Q: Can you support projects during design and construction stages?
A: Yes. We work with design teams early to optimise fire resistance strategies and provide validation during construction for peace of mind.
Q: Will using Structural Fire Engineering reduce costs without compromising safety?
A: Absolutely. By avoiding unnecessary over-specification, we help you achieve compliance and safety while minimising material and protection costs.
Q: Do you provide independent third-party reviews for fire engineering reports?
A: Yes. Our impartial reviews are widely accepted by building control, insurers, and approval bodies.
Q: Can you assess existing buildings for refurbishment or change of use?
A: Yes. We conduct site inspections and desktop studies to evaluate fire resistance in existing structures.
Q: What types of projects benefit most from Structural Fire Engineering?
A: Complex designs, high-rise buildings, refurbishment projects, and structures using innovative materials or hybrid systems often require performance-based fire assessments.
Q: How early should I involve Structural Fire Engineering in my project?
A: Ideally at concept or design stage to maximize design flexibility and cost efficiency. However, we can also get involved at later stages of construction to review fire resistance strategies, validate compliance, and provide independent assessments if design changes or regulatory queries arise.
Q: Are your methods recognised by insurers and approval authorities?
A: Yes. Our evidence-based approach and compliance with international standards make our reports trusted by regulators and insurers.
