How we price fire damper testing
A fixed price needs a few facts first. We look at:
- The number of sites or systems
- Whether we need access equipment or extra panels
- The size of the system
- One-off work versus a regular cycle
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before we start.
Helping us quote
What to send for a quote:
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
Fire damper testing in Radlett
Fire dampers sit inside ductwork where it passes through a fire-resisting wall or floor. A fusible link holds the blade open until heat melts it, and the blade then drops to shut the duct. A drop test shows that the damper still does that when it matters, and we record the result for every damper we test. If you have missing or out-of-date damper records and motorised smoke dampers due for testing, we can help, from offices and schools, motorised smoke dampers and hospitals and care homes onwards.
A building in a smaller place like Radlett might have only a few dampers, and each still needs an annual drop test at least, with the result recorded.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Aftercare tips
Here’s the after-treatment advice, short and simple:
- Update the register when ductwork changes
- Get remedials done soon after a failed test
- Warn anyone working in ceiling voids about the dampers
- Keep damper test reports with the fire safety log
When we finish, we send a report covering every damper on the visit, with its location and its result. File it with your fire safety log so it’s ready when your assessor or insurer asks.
Keep a damper register: location, type, last test date and result. It means nothing gets forgotten when staff or contractors change.

Why act early in Radlett
An untested damper is an unknown. Testing turns it into a known pass or a known fault, with remedials offered for anything that fails, which is far easier to plan for. In a smaller place like Radlett, a site that has to close is felt quickly.
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before work begins.

Questions from Radlett
Which fire and rescue service is responsible for Radlett?
Radlett is in the area of Hertfordshire Fire and Rescue Service. A report listing every damper, its location and its result is the easiest way to show the dampers are maintained.
Can you come to Radlett after we close?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Radlett needn’t be disturbed. Your opening times are the first thing we ask for.
Do you offer emergency callouts?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Is TR19 a legal requirement?
No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
Who is responsible for fire safety on the premises?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
How long does fire damper testing take?
As a guide, it takes a few hours for a single floor, with bigger buildings phased over more than one visit. It comes down mainly to how many dampers there are and how easy they are to get to.
What happens if you cannot reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
How it works
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes a couple of hours for a few dampers, and a day or more across a big site. Everything the job in Radlett needs is worked out beforehand, from the survey.
- We gather what’s known about the dampers, from drawings, registers or past reports.
- Dampers are located one by one and reached through their access panels.
- We release each fire damper blade and operate smoke dampers from their controls.
- Each one that passes is reset, ready to work.
- You get a report listing each damper, its result and any remedials needed.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Let us know when the site is closed or quiet
- Make sure someone can let us in and lock up afterwards
Getting a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.

What the work involves, part by part
Fusible link fire dampers
A damaged or painted link can stop a damper doing its job. Each link is looked at as part of the test and any problems go on the report.
Schools, hospitals and care homes
Where residents cannot easily get out, holding fire and smoke back matters even more. Regular damper testing supports that.
Landlords, agents and facilities managers
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Fire dampers in Radlett buildings
The FSA’s food hygiene register lists about 5 schools, colleges and universities and about 3 hospitals, care homes and childcare premises with registered kitchens or food service within roughly a mile and a half of the centre of Radlett. If any of them has ducted ventilation, its dampers need an annual drop test at least. Radlett sits within the area of Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and keeping dampers working is part of the responsible person’s duty. The nearest hospital to Radlett is Shenley Hospital, about 1.4 miles north-east. Hospitals are a good example of a building with fire dampers across many floors and departments.
A school like St John's Church of England Infant and Nursery School can have any dampers tested over half-term without disturbing lessons. Historic buildings that have had ventilation added later can hide dampers in awkward places; High Elms Manor, about 3.3 miles west, is one of the historic houses in the area around Radlett. Shenley Hospital, about 1.4 miles north-east of Radlett, is the kind of building where dampers protect every compartment; smaller care sites need the same annual tests.

What staff can safely do
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
