If you’re responsible for building maintenance or compliance, you’ve probably been told your property needs fire damper testing — but figuring out what fire damper testing costs (and why prices vary so much) isn’t always straightforward.
We hear it all the time from facilities managers, landlords, and compliance officers across the UK:
“Why does one company quote £15 per damper and another charge £45 or more?”
The truth is, not all fire damper testing is the same, and understanding what you’re paying for can save you serious time, money, and risk down the line.
So, in this post, we’ll break down what affects the cost, what’s included in a proper fire damper test, and how to make sure you’re budgeting correctly for 2025.
Let’s make this simple.
How Much Does Fire Damper Testing Costs in the UK?
As a general rule, fire damper testing costs between £20 and £50 per damper, depending on access, volume, and whether the system includes additional fire duct cleaning or maintenance.
Here’s a quick guide:
| Type of Property | Typical Cost per Damper | Average Total Cost |
|---|---|---|
| Small commercial premises | £20–£30 | £300–£600 |
| Medium office block or healthcare facility | £25–£40 | £750–£1,500 |
| Large site (hospital, school, multi-floor building) | £35–£50 | £2,000+ |
These figures assume annual testing, which is a legal requirement under BS 9999 and the Regulatory Reform (Fire Safety) Order 2005.
But let’s be clear: price isn’t the most important factor — proof is.
Because if a fire damper fails to operate during an inspection or incident, the cost of non-compliance could be devastating.

What You’re Actually Paying For
When you receive a quote for fire damper testing costs, you’re not just paying for a few technicians to open and close dampers.
You’re paying for a safety-critical service that ensures your building’s life-saving systems work exactly as they should.
Here’s what’s typically included in a professional test:
- Accessing each damper (which can involve removing ceiling tiles or duct panels)
- Manual operation and reset testing
- Inspection for corrosion, obstruction, or failed springs
- Cleaning of associated ductwork to remove dust or debris affecting performance
- Photographic evidence and full reporting for compliance
- Asset tagging and test documentation for your fire safety logbook
Every one of these steps takes time — and cutting corners often means compliance failures later on.

Why Prices Vary Between Providers
When you compare quotes for fire duct cleaning and damper testing, you’ll notice big differences. Here’s why:
1. Number and Location of Dampers
A small single-floor office might have 10–20 dampers.
A multi-level hospital could have 500+.
More dampers mean more testing time — especially if access is difficult.
2. Access Requirements
If dampers are behind plasterboard ceilings or hard-to-reach voids, engineers may need scaffolding, ceiling access panels, or specialist equipment.
3. System Condition
Older systems often have rusted or seized dampers that require additional maintenance or cleaning to restore full function.
4. Fire Duct Cleaning Requirements
If your ductwork hasn’t been cleaned in years, debris build-up can affect damper performance.
Many professional services now combine fire duct cleaning and damper testing to save cost and downtime.
5. Certification and Reporting Standards
Always ask what certification you’ll receive.
A proper NAAD21 or BESA-compliant report ensures your results will satisfy insurers, auditors, and the fire safety officer.

The Real Cost of Skipping Proper Testing
Let’s be honest — it’s tempting to go with the lowest fire damper testing costs quote.
But here’s what we’ve seen happen when corners are cut:
A facilities manager for a retail chain hired a company that offered a “bulk discount” of £15 per damper.
When the building underwent a fire safety audit, 40% of the dampers were marked “untested” because access panels hadn’t been opened.
The company failed compliance, had to redo the entire inspection, and lost several days of trading access during remedial works.
That “cheap” test ended up costing them over £5,000 in downtime and reinspection costs.
Price without proof isn’t value — it’s risk.

How Often Should Fire Dampers Be Tested?
According to BS 9999, all fire dampers must be tested and maintained at least once every 12 months.
Some high-risk environments — like hospitals, kitchens, or manufacturing plants — may require more frequent checks.
Combining your annual fire duct cleaning with your damper testing is often the most cost-effective way to stay compliant.
It ensures both your ductwork and safety systems are functioning together as intended.

Why Combine Fire Duct Cleaning and Damper Testing?
These two services go hand-in-hand:
- Fire duct cleaning removes grease, dust, and debris that block airflow and trigger fire spread.
- Fire damper testing ensures your passive fire safety systems close properly in an emergency.
Together, they protect your building and everyone inside it.
That’s why many facilities now book both services during the same site visit — cutting downtime and cost while improving compliance documentation.
