Fire damper testing for kitchens and businesses in Ayot St Peter
Wherever a duct crosses a fire-resisting wall or floor, there should be a fire damper inside it. A fusible link holds the blade open until heat melts it, and the blade then drops to shut the duct. Drop testing proves that this still happens, and we record the result for every damper we test. We’re often asked to deal with smoke dampers with no recent test and dampers that stick or won’t close fully, on hospitals and care homes, offices and schools and fusible link fire dampers.
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.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Honest limits
Not every problem is solved by fire damper testing, and we’d rather say so up front. It will not put right:
- Faults in the alarm or building controls that signal smoke dampers
- Sign-off of the whole building’s fire safety
- Fire risk assessments, which need a fire risk assessor
If you’re not sure, just give us a ring on 0345 646 2711, or email photos and we will give you a straight answer before booking.
Where we work
- Motorised smoke dampers
- Fusible link fire dampers

- Wall and floor dampers
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Keep cables and fixings away from damper blades
- Keep ceiling hatches and duct panels easy to open
- Keep damper test reports with the fire safety log
- Keep an eye out for damp around dampers
After testing, you get a report listing each of the fire and smoke dampers we tested, with its location and its result. File it with your fire safety log so it’s to hand for assessors and insurers.
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.
Multi-site and managed buildings
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
What the work involves, part by part
Access panels
A damper can only be tested if it can be reached. That typically means an access panel in the duct, plus a way through the ceiling or wall.
Smoke dampers
If a smoke damper will not operate when signalled, it goes on the report as a failure, along with what we saw.
Ayot St Peter: your questions answered
Is Ayot St Peter within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Ayot St Peter included. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you test dampers in schools in Ayot St Peter during the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 6 schools, colleges and universities with registered kitchens within about a mile and a half of Ayot St Peter. Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we’ll fit the work in.
How often do fire dampers need drop testing?
BESA guidance is that fire dampers are tested on completion of installation and at least annually after that. For spring-operated dampers, once a year is the minimum.
Is TR19 a legal requirement?
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 cleaning to TR19® is the recognised way to show grease is under control.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What if a damper has no access panel?
Any damper we cannot reach is listed on the report, so you know exactly what’s outstanding. An access panel tends to solve it, and we can quote for it.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Who is the responsible person?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.

Smaller healthcare sites, from surgeries to care homes, need the same annual damper test as a hospital.
