Independent Expert Witness & Litigation Support

Apex Fire Engineering provides independent expert witness services for legal proceedings involving fire safety. Our expert opinion is grounded in operational firefighting experience, technical fire engineering knowledge, and extensive experience of fire risk assessment and fire safety regulation across multiple building types and sectors.

• Fire risk assessment adequacy and compliance disputes
• Regulatory breach under the RRO 2005 and Building Regulations
• Fire causation and fire spread analysis
• Professional negligence in fire safety consultancy
• Contractual disputes involving fire safety works
• Building defects and passive fire protection failures
• Contested EWS1 assessments and PAS 9980 disputes
• Over-specified remediation challenges and second opinions

Duty holders frequently receive overly cautious, commercially damaging fire safety assessments — particularly EWS1 ratings that trap leaseholders and stall property transactions. When a second opinion is needed, Apex's absolute independence is the critical differentiator. We are not incentivised to over-specify remedial works. We provide pragmatic, proportionate, independent verification strictly aligned with the true intent of PAS 9980 — ensuring absolute life safety without demanding unnecessary, exorbitant remediation.

Our second opinion service covers fire risk assessments, FRAEW reports, fire strategies, and fire engineering reports from any provider. We identify whether the original assessment was technically sound, proportionate, and compliant with current standards.

All expert reports are prepared in full compliance with CPR Part 35 requirements. We provide:

• Single joint expert reports
• Joint statements following experts' meetings
• Independent technical reviews for court proceedings
• Oral evidence at trial and tribunal hearings
• Forensic site inspections with court-grade photographic evidence

Our duty is to the court, not to the instructing party. As a genuinely independent consultancy with no product sales, installation contracts, or commercial relationships that could suggest bias, Apex's expert opinion carries the weight of demonstrated impartiality. This independence is not merely a marketing position — it is a structural feature of how the firm operates, and it stands up to cross-examination.

What does a fire safety expert witness do?

A fire safety expert witness provides independent, impartial expert opinion to courts and tribunals on matters involving fire safety. This includes assessing whether fire safety obligations were met, evaluating the adequacy of fire risk assessments or fire safety designs, and providing technical analysis of fire spread, compartmentation failures, or means of escape deficiencies. The expert witness duty is to the court, not to the party instructing them, and all opinions must be objective and evidence-based.

What is CPR Part 35 and why does it matter?

Part 35 of the Civil Procedure Rules governs expert evidence in civil proceedings in England and Wales. It sets the standards for expert reports, requires experts to declare their duty to the court, and establishes the requirements for independence and impartiality. Apex expert witness reports are prepared in full compliance with CPR Part 35 and the Practice Direction, including the required statement of truth, declaration of conflicts of interest, and clear presentation of the basis for each opinion.

What types of cases require fire safety expert evidence?

Fire safety expert evidence is commonly required in disputes between landlords and leaseholders over fire safety costs and remediation obligations, construction defect claims involving passive or active fire protection, regulatory prosecutions under the Regulatory Reform (Fire Safety) Order 2005, insurance claims following fire events, and professional negligence claims against fire safety consultants. Apex has provided expert opinion across each of these case types.

How does expert witness work differ from consultancy?

In consultancy, the fire safety professional acts as an adviser to their client and provides recommendations to achieve a specific outcome. As an expert witness, the professional’s overriding duty is to the court — they must provide an objective, impartial opinion regardless of which party has instructed them. This requires a different approach to investigation, analysis, and reporting. Apex maintains clear separation between its consultancy and expert witness functions to preserve independence.

Can you provide a second opinion on an existing fire safety report?

Yes. Apex regularly provides independent second opinions on fire risk assessments, fire strategies, and fire engineering reports produced by other consultants. This may be for litigation purposes, or simply because the commissioning organisation wants assurance that the original report is technically sound and compliant with current standards. Contact Apex to discuss the scope of the review required.
