Fire Dampers
A fire damper is a passive fire protection device installed where ventilation ductwork passes through fire-rated walls and floors. When triggered by heat, the damper closes automatically, sealing the duct opening and stopping fire and smoke from spreading through the building’s ventilation system. Annual testing is required under the Regulatory Reform (Fire Safety) Order 2005 to verify dampers remain operational and your building stays compliant.
Robinsons Facilities Services delivers certified fire damper installation, testing, inspection and maintenance for commercial buildings across Yorkshire and the North of England.
Our specialist engineers test all common damper types to BS 9999:2017 and BESA DW/145 standards, ensuring your dampers operate as intended and your compliance records are current.

Annual fire damper testing is a legal requirement under the Regulatory Reform (Fire Safety) Order 2005 for responsible persons managing non-domestic premises. BS 9999:2017 and BESA DW/145 outline the standards for testing frequency and procedures. Fire dampers must be tested upon installation and then annually thereafter to verify closure operation and ensure fire compartmentalisation remains effective.
Is fire damper testing a legal requirement?
Yes. The Regulatory Reform (Fire Safety) Order 2005 places a duty on the responsible person to ensure all fire precautions in non-domestic premises are maintained in efficient working order. Fire dampers are fire precautions.
BS 9999:2017 specifies that all fire dampers must be inspected and tested annually by a competent person.
BESA DW/145 sets out the procedures, documentation requirements and competency standards for testing and maintenance.
What fire damper testing involves
Each annual test follows a structured sequence covering identification, physical inspection, operational verification and documentation.
Step 1: Damper identification
We survey the building to locate all fire dampers within ventilation systems, accessing ductwork, plant rooms and roof voids as required. Each damper is logged by type and location, with photographic evidence collected as required by BESA DW/145.
Step 2: Visual inspection
Each damper is inspected for physical damage, corrosion, paint accumulation, debris or wear. Seals, blades and closure mechanisms are examined for degradation that could prevent reliable operation.
Step 3: Operational test
The damper is triggered to confirm it closes reliably and seals fully. For spring-operated dampers, blade freedom and closure are checked. For electrically operated dampers, control signals, closure timing and sealing integrity are verified. Digital photographic evidence is collected before, during and after testing.
Step 4: Remedial action where required
If a damper fails or is found defective, we discuss options: cleaning and adjustment, repair or replacement. Any remedial work is documented alongside the original test findings.
Step 5: Test certificate and compliance records
A test certificate is issued documenting each damper inspected, its condition, test results and any remedial actions. This provides the evidence required to demonstrate compliance under the Fire Safety Order and satisfies insurer and auditor requirements.
Fire damper types and testing standards
Fire dampers vary in design and operation. Our specialist engineers are trained to test all common types to BS 9999:2017 and BESA DW/145 standards.
Spring-operated (fusible link) dampers
Held open by a fusible link that melts when exposed to heat, releasing the spring and closing the damper blades. Testing verifies blade freedom, spring tension and that the closure mechanism operates without obstruction.
Electro-mechanical dampers
Operated by electrical control signals triggered by fire detection systems. Testing verifies electrical continuity, signal reception, closure timing and sealing integrity.
Fire and smoke combination dampers
These block both flames and smoke, providing enhanced compartmentalisation. Testing verifies both fire and smoke sealing functions.
All testing is conducted to BS 9999:2017 and BESA DW/145. BS 9999:2017 specifies testing frequency and acceptance criteria.
BESA DW/145 sets out procedures, documentation requirements and engineer competency standards for installation, inspection and maintenance.
Fire damper testing across Yorkshire and the North of England
Robinsons Facilities Services delivers fire damper testing for commercial buildings across Yorkshire and the North of England, covering North Yorkshire, West Yorkshire, East Yorkshire, South Yorkshire, and surrounding regions.
We serve property managers, facilities teams, healthcare providers, schools, local authorities, and multi-academy trusts across diverse building types: office blocks, hospitals, care homes, educational facilities, retail premises, industrial buildings, and leisure centres.
Our engineers are trained and experienced in testing all damper types and are familiar with the unique ventilation system layouts common across Yorkshire and Northern England commercial properties.
Testing is available as a standalone service or as part of a Planned Preventative Maintenance (PPM) and Compliance contract. Contract customers also benefit from priority response for reactive attendance and access to a separate 24/7/365 out-of-hours call-out facility where required.
Fire damper repair and replacement
If testing identifies that a damper is faulty, repair or replacement may be necessary. Our engineers assess whether repair is practical or replacement is recommended.
Repair
Cleaning, blade adjustment, spring re-tensioning, and replacement of worn seals can often restore damper function. Repair is typically faster and more cost-effective than replacement, provided the damper housing is sound.
Replacement
If a damper is structurally damaged, severely corroded, or beyond practical repair, replacement with a certified equivalent is necessary. We install certified dampers matched to the ductwork size and specification of your ventilation system.
Repair and replacement work is quoted separately and delivered through our Quoted Works service. Contract customers can access out-of-hours support for critical failures through our separate 24/7/365 call-out facility.
Pricing
From £150+VAT
Fire damper testing costs vary based on the number and type of dampers in your building and the complexity of accessing them. A small office with two dampers will cost significantly less than a large multi-storey building with many dampers across multiple floors.
We provide a detailed quote before testing begins.

Fire Dampers FAQs
Yes, if your building has mechanical ventilation with fire dampers installed. The Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to maintain all fire precautions in working order. BS 9999:2017 specifies annual testing as the minimum frequency for most commercial buildings.
BS 9999:2017 requires all fire dampers to be inspected and tested at least once every 12 months by a competent person. In higher-risk environments, including hospitals, laundries, commercial kitchens or dusty industrial spaces, more frequent testing is required. BESA DW/145 provides further guidance on frequency by environment type.
Fire dampers are tested to BS 9999:2017 and BESA DW/145. BS 9999:2017 sets out annual testing frequency and acceptance criteria. BESA DW/145 is the industry standard for installation, inspection, maintenance and documentation of fire and smoke dampers in commercial buildings.
If a damper fails, we assess whether cleaning and adjustment, repair or full replacement is required. Non-functional dampers must be remediated promptly to restore compliance. Under the Fire Safety Order, leaving a known defective damper unaddressed exposes the responsible person to enforcement action.
Yes. Testing is often scheduled alongside ventilation maintenance, boiler servicing or fire safety inspections as part of a PPM contract. This reduces disruption and keeps all critical systems verified on a single visit where possible.
Duration depends on the number of dampers and the complexity of access. A small building with two or three dampers typically takes one to two hours. A large multi-storey building may take a full day or require multiple visits. We provide a time estimate before commencing.
Fire damper testing starts from £150+VAT. Costs depend on the number of dampers, damper type, and accessibility. We provide a detailed quote before testing begins. For buildings with many dampers, annual preventive maintenance contracts often offer better value than individual ad-hoc tests.
A test certificate is issued documenting each damper inspected, its condition, test outcome, photographic evidence and any remedial actions taken. This record satisfies compliance requirements under the Fire Safety Order and is available for inspection by fire authorities or insurers.
Contract customers have access to a separate 24/7/365 out-of-hours call-out facility for urgent fire safety issues outside normal business hours. For non-contract customers, attendance is during business hours. Speak to us about a Planned Preventative Maintenance (PPM) and Compliance contract if out-of-hours cover is a requirement for your site.
