Fire Safety Testing & Certification Services
From duct leakage smoke testing and fire door certification inspections to FM200 integrity testing, thermography imaging, and foam conductivity testing — our certified testing and inspection specialists deliver accurate, documented results that meet regulatory, insurance, and AHJ compliance requirements.
Duct Leakage Testing & Smoke Duct Test Services — HVAC Compliance
Our duct leakage testing services verify the airtightness of HVAC ductwork systems using pressurisation and smoke testing methods — identifying leaks that reduce system efficiency and compromise fire and smoke compartmentation. Testing is conducted to SMACNA, EN 12237, and DW144 standards, with full test reports provided for building compliance sign-off and M&E contractor handover.

Fire Door Certification & Inspection Services — Compliance Surveys
Our fire door certification inspection services assess fire doors against BS 8214, BS EN 1634, and Regulatory Reform (Fire Safety) Order 2005 requirements — checking gaps, seals, hinges, closers, glazing, and signage for compliance. Each door receives a pass/fail certification report with photographic evidence and remedial recommendations. Suitable for new installations, periodic surveys, and post-incident inspections.

FM200 Room Integrity Testing — Fire Suppression System Certification
FM200 room integrity testing (also called enclosure integrity testing) verifies that a protected room maintains sufficient agent concentration to suppress a fire for the required hold time. Using a fan door pressurisation test to ISO 14520 and NFPA 2001 standards, we identify air leakage paths in the enclosure and provide a certified integrity test report — mandatory for FM200, CO2, Novec, and inert gas suppression systems.

Pressure Relief Vent (PRV) Installation for FM200 & Gas Suppression Rooms
Pressure Relief Vent (PRV) installation is essential for rooms protected by FM200 and other gaseous suppression systems. When agent discharges, the rapid pressure rise can structurally damage the enclosure if PRVs are not correctly sized and installed. Our engineers calculate the required vent area to ISO 14520 and NFPA 2001 standards and install certified PRVs — protecting both the structure and the suppression system investment.

Thermography Imaging & Thermal Inspection Services — Electrical & Building Surveys
Our thermography imaging services use infrared thermal cameras to identify heat anomalies in electrical panels, switchgear, cable trays, motors, and building envelopes — detecting failing components, overloaded circuits, moisture ingress, and insulation defects before they cause fires or failures. Thermal imaging surveys are non-invasive, conducted under live load conditions, and deliver a full thermographic report with categorised findings and recommended actions.

Foam Conductivity Testing & Certification — Fire Suppression Foam Quality Testing
Our foam conductivity testing services assess the electrical conductivity of firefighting foam concentrates and solutions — critical for data centres, server rooms, and electrical equipment protection where low-conductivity foam must be verified to prevent electrical damage during suppression discharge. Tests are conducted to manufacturer and system specification standards, with a full conductivity test certificate issued on completion.

Fire System Inspection, Rectification, Labelling & DRI Services
Our fire system inspection, rectification, and labelling services cover the full compliance lifecycle of passive and active fire protection installations — from initial inspection and defect identification through to rectification works, system labelling, and DRI (Defect, Rectification & Inspection) documentation. Each completed project is issued with a DRI certificate demonstrating compliance with fire safety regulations and insurer requirements — critical for building sign-off, insurance renewal, and fire authority audits.
