About our Fire Damper Testing Service

Protect your building with professional fire damper testing and inspections, and fire damper maintenance services. We help facilities managers, duty holders, and building owners achieve fire safety compliance through thorough testing, detailed reporting, and expert remediation advice.

Our comprehensive fire damper testing and inspection service ensures your building's passive fire protection systems operate correctly in the event of a fire.

We inspect and functionally test all fire and smoke dampers throughout your ventilation system, documenting their condition, accessibility, and operation in accordance with BS 9999, DW145, and other relevant UK guidance.

Every inspection includes detailed photographic evidence, compliance reporting, and practical recommendations where remedial work or fire damper maintenance is required. This helps building owners demonstrate fire safety compliance, reduce risk, and maintain a safe environment for occupants.

Fire Damper Testing FAQs

How often should fire dampers be tested?

UK regulations require fire dampers to be tested at least once every 12 months. Initial testing should be conducted after installation, with ongoing annual inspections thereafter. Buildings with higher fire risks or critical operations may require more frequent testing.

What standards govern fire damper testing?

Fire damper testing must comply with BS 9999, DW145 guidance from BESA, and the Building Regulations Approved Document B. Our testing procedures adhere to all current standards, including the upcoming 2024 revision of DW145.

What does the testing process involve?

Our testing includes visual inspection of damper condition, functional operation testing, verification of correct installation, and documentation of results. We check for obstructions, damage, corrosion, and ensure fusible links are intact and operational.

How do you access fire dampers for testing?

We access dampers through existing maintenance access panels where available. For dampers without proper access, we can advise on the installation of access panels to ensure compliance with regulations that require all fire dampers to be accessible for inspection.

What documentation do you provide?

We provide comprehensive documentation including inventory of all dampers tested, photographic evidence, detailed findings, pass/fail status, and specific recommendations for remedial work if required. This documentation serves as evidence of compliance for insurance, fire safety officers, and building certification.

Is a fire dampener the same as a fire damper?

Yes. "Fire dampener" is a common search term, but the correct engineering term is fire damper. The same goes for "smoke dampener" as smoke damper.

Fire and smoke dampers are passive fire safety devices installed within ventilation ductwork to prevent the spread of fire and smoke between compartments.
