Fire damper testing for kitchens and businesses in St Margarets
BESA guidance is that fire dampers should be tested by a competent person when they’re installed and at least annually after that. Spring-operated dampers need testing every year as a minimum. We carry out fire damper testing for buildings in St Margarets and give you the records to show it’s been done. If you have damper actions from a fire risk assessment and fire dampers nobody can get to, we can put it right.
Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, where the dampers are easy to overlook. The first visit starts by locating each damper.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Fire damper testing around St Margarets
There are about 16 schools, colleges and universities and about 12 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register within 1.5 miles or so of the middle of St Margarets. If any of them has ducted ventilation, its dampers need an annual drop test at least. About 3.8 miles west of St Margarets is Hertford County Hospital, the nearest hospital. Healthcare buildings rely on fire compartments to protect people who can’t easily move, and dampers keep those compartments sealed. Hertfordshire Fire and Rescue Service covers St Margarets. Under the Fire Safety Order, the responsible person has to keep fire safety systems, dampers included, in working order, and the fire authority enforces that in most non-domestic premises.
For schools like The Cranbourne Primary School, damper testing is easiest in the holidays, when corridors and ceilings are clear. The nearest hospital, Hertford County Hospital, is about 3.8 miles west; healthcare buildings like it are a reminder that dampers protect people who can’t move quickly.

Near you in St Margarets

What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
What we do, step by step
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes a morning or an afternoon for a small number of dampers, longer where there are many. Visits to a village like St Margarets are booked in advance, at a time that suits whoever runs the site.
- Before the visit, we agree access, timings and any areas with restrictions.
- Ceiling tiles and hatches are opened and each damper’s access panel removed.
- The blade is released and watched to make sure it closes fully.
- The damper is reset and its condition noted.
- Panels and tiles go back, and the results are written up.
Preparing for the visit
- Let us know when the site is closed or quiet
- Plan for cooking equipment or plant to be off before we arrive
- Arrange a key holder or contact on site
How to get a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, ring 0345 646 2711, or email photos.

St Margarets: your questions answered
Can a school’s dampers in St Margarets be tested out of term time?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 16 schools, colleges and universities with registered kitchens within about a mile and a half of St Margarets. Booking early in the term gives the best choice of holiday dates.
Do you work at weekends in St Margarets?
Yes. We work evenings, overnight and at weekends. The work in St Margarets can fit around your hours. Just call us on 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Is TR19 a legal requirement?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and without records, many insurers may refuse or reduce a claim.
What about areas you cannot get to?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
How long does fire damper testing take?
Testing takes from an hour or two in a small building to several visits on a large estate. Bigger sites can be phased, and you can ring 0345 646 2711 or email us to talk it through.
How often do fire dampers need drop testing?
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.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Aftercare tips
Once we’ve finished, these simple steps help:
- Keep damper test reports with the fire safety log
- Don’t let hatches get painted shut or boarded over
- Do not let anything obstruct a damper’s blade
- Get remedials done soon after a failed test
Share the results with your fire risk assessor, so the assessment reflects where the dampers stand. Outstanding faults should be dealt with, not left on file.
A simple register of every damper helps a great deal: location, type, last test date and result. It stops dampers getting lost as the building changes.
What the work involves, part by part
Schools, hospitals and care homes
In schools and colleges, testing fits well into holidays and weekends, when ceilings can be opened without disturbing lessons.
Smoke dampers
A smoke damper that doesn’t respond to its controls is recorded as a fault, with a note of what we found.
