Fire damper testing in Green Street
BESA guidance is that fire dampers should be tested by a competent person when they’re installed and at least annually after that. For spring-operated types, annual testing is the minimum. We carry out fire damper testing for buildings in Green Street and give you the records to show it’s been done. We’re often asked to deal with fire damper items raised by an assessor and dampers that can’t be reached without an access panel, across fusible link fire dampers, wall and floor dampers and riser dampers.
For a building in or near Green Street, the visit is planned ahead, with access agreed in advance, and the test itself is the same as in any city building.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

In-house cleaning or a specialist?
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, next to our reports.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Green Street questions
Can you come to Green Street after we close?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Green Street needn’t be disturbed. Your opening times are the first thing we ask for.
Can a school’s dampers in Green Street be tested out of term time?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 8 schools, colleges and universities with registered kitchens within about a mile and a half of Green Street. Booking early in the term gives the best choice of holiday dates.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. Before we leave, we tidy up and clean down.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
How do you deal with dampers that can’t be reached?
Any damper we cannot reach is listed on the report so nothing is quietly missed. Fitting an access panel is the usual fix, and we can quote to fit one.
Who has the legal duty for fire safety?
The law calls them the responsible person. That is generally the employer or the person in control of the premises, and where several people have control, each can have duties. If you are not sure, check your lease and fire risk assessment.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
What we’re called out for in Green Street
Buildings in Green Street change owners, tenants and maintenance contractors over the years, and damper records often get lost along the way. Without a register, nobody knows how many dampers there are or when they were last tested.
Any of these means the system needs a check-up:
- Dampers clogged with dust or grease
- Dampers that cannot be reached without an access panel
- Fire dampers that fail to drop shut
- Gaps in the fire damper test log
If you manage a care home or clinic near Green Street, the testing that a hospital like Shenley Hospital (about 1.6 miles north-west) relies on applies to your dampers too.

When it’s something else
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- Fire alarm or control system faults behind a smoke damper
- Missing dampers that a designer needs to specify
- Holes around ductwork in fire-resisting walls

What fire damper testing looks like in Green Street
The FSA’s food hygiene register lists about 8 schools, colleges and universities, about 15 hospitals, care homes and childcare premises and about 4 hotels, B&Bs and guest houses with registered kitchens or food service within 1.5 miles or so of the middle of Green Street. If any of them has ducted ventilation, its dampers need an annual drop test at least. Fire safety in Green Street falls to 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. About 1.6 miles north-west of Green Street is Shenley Hospital, the nearest hospital. Where patients or residents may need help to leave a building, working dampers matter all the more.
For schools like Parkside Community Primary School, damper testing is easiest in the holidays, when corridors and ceilings are clear. Historic buildings that have had ventilation added later can hide dampers in awkward places; Wyllyotts Manor, about 3.7 miles north-east, is one of the historic houses in the area around Green Street.

Part by part
Access panels
A damper can only be tested if it can be reached. Most need an access panel in the duct and a hatch in the ceiling or wall.
Offices and retail
In shared buildings, some dampers sit inside tenants’ space. Access to each area is planned with whoever manages the building.
Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Warn anyone working in ceiling voids about the dampers
- Never wedge or tie a damper open
- Update the register when ductwork changes
- File every damper report where your assessor can find it
The next test should be no more than a year away. BESA guidance is at least annual testing, and booking the same month each year keeps it simple.
Good access is half the battle. Where there’s no hatch, an access panel makes testing possible ahead of the next visit.
How the visit works
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes a couple of hours for a few dampers, and a day or more across a big site. If you can send pictures, we can arrive in Green Street knowing what to expect.
- Before the visit, we agree access, timings and any areas with restrictions.
- We open up ceilings and hatches and take off each access panel.
- We release each blade and check it shuts all the way.
- The damper is reset and its condition noted.
- Panels and tiles go back, and the results are written up.
How to prepare
- Have your last certificate or report to hand
- Mention any parking or loading restrictions
- Name a contact who can let us in at the agreed time

Why it’s worth doing now in Green Street
Until a damper has been dropped, you cannot say whether it works. A test gives you a clear answer, and we can offer remedials for any that fail, which is far easier to plan for. Rural sites cannot always move to another kitchen or room when something fails.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
Why book with us
- Fixed quotes from a survey or photos
- We diagnose before we treat
- CHAS, SafeContractor and ISO 9001
- A written report with photos after every visit
