Fire Damper Certification
When it comes to fire safety and air quality within buildings, fire dampers play a crucial but often overlooked role.
They are an essential part of a building’s passive fire protection system — designed to automatically close when temperatures rise, preventing the spread of fire and smoke through ventilation ducts.
However, simply installing fire dampers is not enough. To ensure they work effectively in an emergency, they must be properly certified, tested, inspected, and maintained.
At Clean Air 24 Seven, we specialise in ensuring your fire damper systems are fully compliant, safe, and certified. This cornerstone page explains what fire damper certification means, the legal requirements involved, and how our team can help you meet your obligations and safeguard your property.

What Is Fire Damper Certification?
Fire damper certification is the formal process that confirms your fire dampers meet recognised standards and will perform correctly under fire conditions. Certification provides documented assurance that dampers are manufactured, installed, and maintained according to British and European standards.
The process includes:
Product or Type Approval – Ensuring the damper has been tested under controlled fire conditions and approved to the correct standards (e.g., BS EN 1366-2).
Declaration of Performance and Marking – Each certified damper carries a Declaration of Performance (DoP) and the appropriate CE or UKCA marking to prove it meets required performance levels.
Correct Installation – Dampers must be installed exactly as they were during testing; any deviations can invalidate certification.
Inspection and Maintenance – Ongoing testing and maintenance ensure that dampers continue to operate correctly and retain certification validity.
Comprehensive Documentation – Certified reports, test results, and maintenance logs provide a full audit trail for compliance and insurance purposes.
Certification provides building owners and responsible persons with proof that fire dampers will work when they are needed most.
Fire Damper Certification Standards and Legislation
BS 9999:2017
This British Standard provides guidance on fire safety management and states that all fire dampers must be tested by a competent person upon installation and at regular intervals not exceeding 12 months. In high-risk or dusty environments, more frequent testing is required.
DW145 (Healthcare Premises)
For hospitals and healthcare facilities, DW145 sets stricter standards for accessibility, installation, and inspection frequency, ensuring fire compartmentation integrity in sensitive environments.
Regulatory Reform (Fire Safety) Order 2005
Under this legislation, the building’s “responsible person” is legally required to ensure all fire safety systems, including fire dampers, are maintained in efficient working order. Non-compliance can lead to prosecution and significant fines.
EN 1366-2: Fire Resistance Testing for Dampers
This European test standard defines how dampers must be tested to verify their integrity (E), insulation (I), and leakage (S) performance. Classifications such as EIS 60, EIS 90, or EIS 120 indicate how many minutes a damper can withstand fire exposure.

Why Fire Damper Certification Matters
Protecting Life and Property
Fire dampers are a frontline defence in stopping fire and smoke from spreading through ventilation systems. Certification ensures they will perform correctly, protecting building occupants and reducing fire damage.
Legal Compliance
Failing to test, maintain, or certify fire dampers can lead to enforcement notices, fines, or even prosecution under the Fire Safety Order. Certification provides documented compliance for fire safety inspections.
Insurance and Liability Protection
Insurance companies often require proof of fire safety compliance. If a fire occurs and certification records are missing, insurers may reject claims or reduce payouts.
Preparedness for Audits and Inspections
Fire authorities and building inspectors routinely check fire safety documentation. Having valid fire damper certification demonstrates proactive compliance and avoids costly remediation.
Cost Efficiency and System Longevity
Regular inspection and certification help identify issues early, preventing mechanical failure or costly replacements later on. A well-maintained system lasts longer and performs more reliably.
The Fire Damper Certification Process
At Clean Air 24 Seven, our certification process is detailed and fully compliant with industry best practice.
Survey and Audit – We begin with a full site survey to locate and record every fire damper within the system. A detailed register and asset map are created for tracking and documentation.
Document Review – We review existing installation drawings, manufacturer certificates, and Declaration of Performance records to verify that installed dampers match their certified design.
Visual Inspection – Our engineers check each damper for accessibility, damage, corrosion, obstructions, and correct installation.
Operational (Drop) Testing – We perform either manual or motorised drop tests to confirm that each damper closes and resets properly. Any failures are documented and rectified.
Cleaning and Maintenance – Dampers are cleaned to remove dust, grease, or debris that might affect operation. Moving parts and fusible links are checked and lubricated if necessary.
Repairs and Replacements – Where faults or non-conformances are found, we carry out or recommend repairs and replacements using approved components.
Certification and Reporting – Upon completion, we provide a detailed report including test results, photographs, and certificates confirming compliance.
Scheduled Recertification – To maintain compliance, we schedule regular re-inspections (typically every 12 months or more frequently where required).
Common Issues and Pitfalls – Even well-designed systems can lose certification integrity if certain mistakes occur. Common issues include:
- Incorrect Installation – If installed differently from the tested configuration, certification becomes void.
- Poor Access – Lack of access hatches prevents inspection and testing.
- Inadequate Sealing – Gaps or incorrect sealing materials compromise fire resistance.
- Dirty or Obstructed Dampers – Dust or grease can prevent dampers from closing properly.
- Untrained Personnel – Testing must only be performed by competent, trained engineers.
- Missing Records – Without documentation, compliance cannot be proven even if the dampers work.
Avoiding these pitfalls through regular, professional certification keeps your building safe and compliant.

How often should fire dampers be tested?
At least every 12 months, or more frequently in dusty or high-risk environments.
-
Who can certify fire dampers?
Only competent and trained professionals with knowledge of fire safety standards can perform testing and issue certification.
-
What happens if a damper fails a test?
Repairs or replacements are carried out immediately, followed by retesting to restore compliance.
