Leicestershire Fire Damper Testing Services
Fire dampers are a critical mechanism installed in properties where they are designed to act as the first defence against fire, closing automatically when triggered by sensors that detect a rise in temperature. This vital fire prevention method effectively prevents the rapid spread of smoke and fire, allowing occupants to safely evacuate and helping to reduce the amount of damage to properties and their contents.
It has been recorded that as many as 20% of fire dampers in Leicestershire fail during testing as a result of issues such as blockages, poor installation and the build-up of dirt and grime. This alarming statistic on fire damper failure rates highlights the importance of regular testing, cleaning, and maintenance.
At Swiftclean, our team of experienced specialists work to deliver reliable, efficient and affordable fire damper testing throughout Leicestershire. This comprehensive service ensures that your building is safe and compliant with the necessary legal requirements and fire safety regulations.

What Are Fire Dampers and Why Are They Important?
Fire dampers are passive fire protection devices strategically installed in HVAC ductwork or ventilation openings. Essentially, they function as a critical safety barrier, designed to automatically close when detecting high heat in order to prevent the spread of flames, smoke, and toxic gases throughout a building.
These life-saving mechanisms are primarily constructed from fire-resistant materials like galvanised or stainless steel, enabling them to withstand extreme temperatures while maintaining structural integrity. A standard fire damper consists of several key components:
- Frame – Rectangular or square, made from heat-resistant materials
- Blades – Flat panels that move to seal off the damper
- Fusible link or actuator – The operational mechanism triggering closure
Furthermore, fire dampers come in three main varieties, each serving specific requirements:
- Curtain Fire Dampers – The most common type, featuring a folded curtain held open by a thermal link that drops when heated
- Intumescent Fire Dampers – Using materials that expand when exposed to high temperatures, ideal for space-limited locations
- Motorised Fire Dampers – Activated by building fire alarm systems, suitable for areas requiring maintained airflow
The importance of these devices cannot be overstated. Above all, they maintain fire compartmentation by preventing one of the most common pathways for fire spread: ventilation systems. Without properly functioning fire dampers, flames can rapidly move through ductwork, reaching areas far beyond the initial blaze.
Notably, while fire itself is dangerous, smoke and toxic gases cause the majority of fire-related fatalities. With their smoke sealing capabilities, fire dampers are able to effectively prevent these hazardous substances from circulating throughout a building.
Additionally, these devices contribute to preserving the structural integrity of fire-rated walls, floors, and ceilings by closing off ducts and helping prevent fire from weakening these barriers. This provides occupants with precious additional time to evacuate safely, while also limiting property damage.
The experts at Swiftclean understand that testing fire dampers is not merely about regulatory compliance – it’s about saving lives. That’s why we provide customers with comprehensive, tailored fire damper testing services to ensure that these critical systems are operating at peak efficiency.
What Happens During a Fire Damper Test?
The testing of fire dampers involves a meticulous process, which is why utilising the services of a qualified and experienced professional is always advisable, especially for larger or more complex properties. Comprehensive fire damper tests follow a structured sequence to ensure that the critical safety components function properly when needed.
Prior to commencing the test, our engineers will ensure the HVAC system is switched off to prevent unexpected airflow. Subsequently, they will locate and access the damper through designated access panels or hatches in the ductwork. Proper access is crucial – all fire dampers must be accessible through builder’s hatches or ductwork panels to facilitate regular testing.
Once accessed, the testing process unfolds in several stages:
- Visual inspection of the damper components, checking for damage, corrosion, or obstruction
- Manual release of the fusible link to simulate emergency activation
- Observation of the damper’s closure, ensuring it drops cleanly and seals 100% without intervention
- Cleaning of channels, runners, and blades to remove accumulated dust and debris
- Application of light lubrication where necessary to ensure smooth operation
- Replacement of damaged fusible links if required
- Careful resetting of the damper to its fully open position, ready for emergency activation
Our specialist assessors will then document all findings in detail, including any required photographic evidence of testing to satisfy authorities that proper assessment has been conducted. Though the basic testing process appears straightforward, it requires skilled technicians that understand the various damper types and their specific operational requirements.

More resources and best practice
Fire dampers are in almost constant use, making it essential to ensure they close reliably when needed. By providing a barrier that prevents fire from spreading, properly functioning fire dampers save lives. This makes regular fire damper testing, cleaning, and maintenance not only a legal requirement but also a critical part of any building’s fire safety strategy.
Swiftclean is one of the UK’s leading specialist building services providers, offering fire damper testing, cleaning, and maintenance in line with BS 9999:2017, which now specifies that all fire dampers must be tested, cleaned, and maintained at least annually.
Everyday operation of ventilation systems leads to a build-up of dust, debris, and other contamination on dampers and their moving parts. Regular cleaning and testing ensure they function correctly in the event of a fire. In sensitive environments such as healthcare facilities, Swiftclean also complies with Health Technical Memorandum (HTM) 03-01: Specialised ventilation for healthcare premises, helping clients establish testing schedules in agreement with local fire prevention officers.
As a trusted fire damper testing company, Swiftclean prides itself on meticulous care and expertise. All staff conducting tests are fully qualified and provide clear guidance throughout the process. We offer professional advice, recommendations, and a clear plan for next steps to maintain the safety and compliance of your building.
Fire damper testing should always be carried out by a competent, qualified professional.
Fire Damper – Open
Fire Damper – Closed
One of the main challenges in fire damper testing is identifying, locating, and accessing each damper within a building’s ductwork. Without expert knowledge, dampers can easily be overlooked or left unmaintained, compromising the safety system. Even when located, many dampers are hard to reach, making it essential to have access in order to inspect and test the internal blades properly. Thorough testing requires skill, experience, and the right equipment to ensure every damper operates effectively when it’s needed most.
Following the completion of your fire damper testing, we will provide you with a comprehensive written report to confirm compliance with BS 9999:2017. This report serves as an essential record for your fire safety management and should be kept on file.
Your report will include:
- Before and after photographs of each fire damper
- Damper numbers and exact locations for full traceability
- Detailed findings and outcomes of the inspection
This documentation provides clear evidence of compliance and can be presented to a Safety Compliance Officer or relevant authority if required, giving you complete confidence in the fire safety of your building.
