Fire & Smoke Damper
Testing & Reporting
Inspection and operational testing of fire and smoke dampers in commercial ventilation systems across Yorkshire. We identify the damper type, access requirements and applicable test scope, with clear records of tested, failed and inaccessible assets.
If a damper we certify is later found non-compliant due to an error on our part, we re-test and remediate it free. Every damper is drop-tested, cleaned and photographed by our own BESA-qualified engineers — never subcontracted — and reported to DW/145 and NAAD-22, so your insurer, auditor or enforcement officer accepts it first time.
Fire dampers, smoke dampers and smoke-control systems
Not every damper is tested in the same way. Mechanical fire dampers, actuated fire/smoke dampers and smoke-control dampers have different operating and control arrangements. The survey identifies which assets are present, how they can be accessed and what testing can safely be completed.
For building smoke-control systems and AOVs, see the separate smoke-control and AOV testing page. System-level testing, control interfaces and specialist attendance must be agreed in the scope; a damper inspection does not by itself certify the whole system.
Useful information for a quote
Send the site postcode, damper schedule or drawings, previous test report, known defects and any ceiling or access restrictions. If quantities are unknown, tell us rather than guessing.
Clear asset-level findings
Records identify the asset, location, test outcome, photographs and recommended action. Inaccessible dampers are recorded as inaccessible, not marked as passed.
Duct hygiene can be planned alongside testing: supply and extract ventilation cleaning to TR19 Air 2026.
What Are Fire Dampers and Why Do They Fail?
Fire dampers are passive fire protection devices installed in ductwork where it passes through fire-rated walls, floors and ceilings. When a fire occurs, they close automatically to prevent the spread of fire and smoke. But only if they work.
Untested fire dampers put lives at risk:
- Dampers can seize open due to corrosion, grease build-up or mechanical failure
- A failed damper allows fire and smoke to travel freely through ductwork — bypassing fire compartmentation
- Building owners face prosecution under the Fire Safety Order 2005 for failure to test
- Fire insurance may be invalidated if dampers are not tested at the required frequency
- Buildings that house vulnerable people (care homes, hospitals, schools) face strict regulatory scrutiny
- Fire risk assessments will flag untested dampers as a critical outstanding action
Who Needs Fire Damper Testing?
Any building where ductwork passes through fire-rated compartment walls or floors. This includes offices, schools, hospitals, care homes, hotels, restaurants, warehouses and apartment blocks.
ALL COMMERCIAL BUILDINGSHow Often Must They Be Tested?
BS 9999 recommends fire damper testing at intervals not exceeding one year. Damper type, manufacturer guidance, environmental conditions and healthcare or smoke-control requirements may call for a different programme. We agree the applicable scope for your assets.
MINIMUM ANNUALLYWho Is Responsible?
The Responsible Person under the Regulatory Reform (Fire Safety) Order 2005 — typically the building owner, employer or facilities manager — has a legal duty to ensure fire dampers are maintained and tested.
LEGAL DUTY OF CAREWhat Does BS 9999 Require?
BS 9999 is the British Standard for fire safety in the design, management and use of buildings. It provides detailed requirements for the maintenance and testing of fire dampers, complemented by BESA DW145 which covers the practical installation and testing methodology.
Full Visual Inspection
Each damper must be visually inspected for signs of damage, corrosion, grease contamination, and any obstructions that could prevent correct operation.
Operational Testing
Every damper must be physically operated to confirm it closes fully and reopens correctly. This requires access and often involves working at height in ceiling voids.
Remediation Where Required
Failed dampers must be repaired or replaced. We carry out on-the-spot remediation where possible and provide a clear remediation report for any work that requires further action.
Compliance Documentation
A full test report is provided for every damper — pass or fail — with location, test result, any remedial action taken, and photographic evidence. This supports your fire safety maintenance records; outstanding defects and access limitations must still be addressed.
What We Do on Every Visit
Damper Location Survey
We identify and log every fire damper on site, including those that may not be on existing records. Each is assigned a reference number.
Access & Inspection
Each damper is accessed, inspected for damage and contamination, and photographed before testing begins.
Operational Test
Each damper is triggered and tested to confirm it closes fully and re-opens correctly. Results are recorded in real time.
Remediation & Report
Failed dampers are remediated where possible. A full written test report with all results, photos and remediation actions is issued upon completion of works and receipt of payment.
Fire Damper Testing FAQ
How long does fire damper testing take?
This depends entirely on the number of dampers and their accessibility. A small office building with 10-20 dampers may take half a day. A large commercial building with 100+ dampers could take 2-3 days. We'll provide a time estimate when we survey your site.
Do we need to vacate the building during testing?
Generally no — testing can be carried out while the building is occupied. However, we may need brief access to ceiling voids and plant rooms. We'll coordinate with your facilities team to minimise disruption.
What happens if a damper fails the test?
We'll attempt on-the-spot remediation for common failures (e.g. cleaning, lubrication, blade adjustment). For dampers requiring replacement, we'll provide a written quotation and temporary risk management advice.
What documentation do we get?
A full test report listing every damper tested, its location, test result (pass/fail), any remedial action taken, and photographic evidence. This is issued after completion of works and receipt of payment for your compliance records.
We've never had our dampers tested — where do we start?
Start with a site survey. We'll locate all dampers, assess their condition and produce a full report. Many buildings don't have an accurate damper schedule — we'll create one for you as part of the service.
The YPAC Compliance Guarantee — Pass or We Fix It Free
Most fire damper certificates we see would not survive an audit: no drop test carried out, no photographs, dampers that do not match the asset register. We built our reporting to change that — every damper we test is documented to BS 9999 with DW/145 and NAAD-22 standard reporting, so the record stands up on its own.
- Every damper drop-tested, cleaned and reset — the functional test is the whole point, and we do it properly on every single one.
- Photographic evidence for every damper — as found, tested position, and as left, so nothing is taken on trust.
- Reports an auditor or insurer accepts — DW/145 and NAAD-22 standard reporting with a full asset register, unique damper references and next test dates.
- Our guarantee: if a damper we certify is later found non-compliant due to an error on our part, we re-test and remediate it free.
- Never subcontracted — all testing is carried out by our own BESA-qualified engineers (AHO3 & AHT3).
Because we keep the work in-house, we take on a limited number of new compliance clients each month. Compliance certification issued on completion of works.
