Your questions about fire damper testing in Nettleden
Who enforces fire safety at workplaces in Nettleden?
It’s Hertfordshire Fire and Rescue Service, which covers Nettleden. A report listing every damper, its location and its result is the easiest way to show the dampers are maintained.
Can fire dampers in schools around Nettleden be tested in the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Nettleden. Just give us a ring on 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
How often does BESA say fire dampers should be tested?
BESA’s guidance is a test on installation and at least once a year after that. Your fire risk assessment may call for some dampers to be tested more often.
Is TR19 cleaning required by law?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
What happens to dampers you cannot get to?
We do not leave it off the report; we note it as not reached. With an access panel fitted, it can be tested on a return visit.
What paperwork do we get after testing?
You get a test report recording every damper we tested, with its location, its result and any faults. It belongs in your fire safety log.
How far ahead should we book?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Are you fully insured?
Yes. We carry full insurance and have been trading since 2009.
Fire damper testing in Nettleden
Each damper we test gets a location, a result and a note of its condition. Dampers that pass are reset and left open, ready to operate, while failures are flagged with what we found. You end up with a clear record to keep with your fire safety documents. The work covers riser dampers, wall and floor dampers and hospitals and care homes, and the jobs we see most are dampers flagged on a fire risk assessment and blades that jam part-way when released.
Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, and the dampers in them are easily forgotten. A first test normally starts with finding them all.
The paperwork matters as much as the work. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Nettleden buildings and fire safety
Food Standards Agency records list about 3 schools, colleges and universities and about 5 hospitals, care homes and childcare premises registered as food businesses within roughly a mile and a half of the centre of Nettleden. Schools, care settings and hotels are the kind of buildings where fire dampers are commonly found. Nettleden’s nearest hospital, Hemel Hempstead Hospital, is about 3.1 miles south-east. Healthcare buildings rely on fire compartments to protect people who cannot easily move, and dampers keep those compartments sealed. Nettleden is covered by Hertfordshire Fire and Rescue Service. Its fire safety officers enforce the Fire Safety Order in most non-domestic buildings, and that covers fire safety systems such as dampers.
If you manage a care home or clinic near Nettleden, the testing that a hospital like Hemel Hempstead Hospital (about 3.1 miles south-east) relies on applies to your dampers too.

Staff cleaning versus specialist work
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Common problems we fix in Nettleden
Corrosion is another common cause of failure. Condensation, leaks and damp plant rooms corrode the parts that need to move, and the damper can seize quietly where no one sees it.
Signs it’s time to call us include:
- Dirty dampers that may not close
- Fire dampers with no recent test record
- Dampers that cannot be reached without an access panel
- Fire damper items raised by an assessor
For schools like Great Gaddesden Church of England Primary School, damper testing is easiest in the holidays, when corridors and ceilings are clear.

Multi-site and managed buildings
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Honest limits
To be straight with you, there are a few things this work will not fix:
- Designing the building’s fire compartments
- Dampers that were never installed where they’re needed
- Approving the building’s fire strategy
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we will tell you honestly.
What the work covers
- Fusible link fire dampers
- Wall and floor dampers
- Riser dampers
- Motorised smoke dampers
- Hospitals and care homes
- Offices and schools
What the work involves, part by part
Smoke dampers
Testing smoke dampers sometimes needs input from whoever looks after the control system. We agree the arrangements with you in advance.
Offices and retail
Offices and shops often have dampers above ceilings that are rarely opened. Testing can be done outside opening hours so the space stays open.
How we price fire damper testing
You’ll get a fixed price before we start. It’s based on:
- Access, including roofs, risers and ceiling voids
- Parking and loading at the site
- The condition of the system
- When the work can happen, such as evenings, overnight or weekends
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before work begins.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- Wide photos of the system and the area around it
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
What we do, step by step
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes a few hours for a single floor, with bigger buildings phased over more than one visit. Photos of the system and how to reach it help us plan a visit to Nettleden.
- We plan access and timing with you first, including any out-of-hours work.
- We open up ceilings and hatches and take off each access panel.
- The blade is released and watched to make sure it closes fully.
- We reset it and record any dirt, corrosion or damage.
- We close everything up and send the results in a report.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Tell us where we can park and unload
- Plan for cooking equipment or plant to be off before we arrive
How to get a quote
Getting a quote does not take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
