What are fire dampers?
Fire dampers are safety devices fitted within HVAC ductwork that automatically close when heat from a fire is detected. That stops fire and smoke spreading through ventilation systems — helping to contain the event to its origin.
They are a vital part of any coordinated fire protection strategy in buildings with mechanical ventilation.
Where fire dampers are used
If your building uses ducted air systems, there’s likely a requirement to control smoke and fire spread via dampers.
- Commercial offices
- Retail and hospitality spaces
- Healthcare facilities
- Schools and universities
- Industrial buildings with ventilation systems

Designed for compliance. Built for performance.
Strong design. Accurate installation. Proper records.
Fire dampers must meet strict UK standards and building regulations. We assess your ventilation layout, then supply and install fire dampers that:
- Fit your ductwork and architecture
- Integrate with fire detection and building systems
- Operate reliably when triggered
- Come with certification and documentation
Fire damper servicing and maintenance
Like all life-safety components, fire dampers need routine inspection and testing to stay ready.
Our maintenance visits cover:
- Mechanical operation checks
- Actuator and linkage performance
- Integration with fire alarm signals
- Documentation of test results
Scheduled maintenance gives you confidence that dampers will close when they need to.
FAQ: Fire Dampers
What triggers a fire damper to close?
Fire dampers typically close when a linked heat detector or fire alarm signal detects elevated temperature, activating the damper’s mechanism.
Are fire dampers required by law?
Where ductwork penetrates fire-resisting compartments, fire dampers are often required under UK building regulations and fire strategy guidance to help maintain compartmentation.
How often should fire dampers be tested?
Industry standards and manufacturers recommend annual or biannual testing by a competent engineer to confirm mechanical operation and integration with fire systems.
