Fire damper testing in Southfields, Greater London
Fire damper testing in Southfields from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Rusted damper blades and springs
- Blades that jam part-way when released
- Dust or grease build-up on damper blades
Between visits
How long the results last depends on use and care. We suggest:
- Keep an eye out for damp around dampers
- Keep cables and fixings away from damper blades
- Keep the damper register up to date after any building work
- Don’t let hatches get painted shut or boarded over
Failed dampers are set out separately, each with the fault we found, along with an offer to repair or replace them. After a repair, we retest the damper and update the record.
Keep a damper register: location, type, last test date and result. It stops dampers getting lost as the building changes.
Fire damper testing for kitchens and businesses in Southfields
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. The work covers offices and schools, fusible link fire dampers and riser dampers, and people most often call us about rusted damper blades and springs and smoke dampers with no recent test.
Damper testing in London buildings is typically planned around the people in them, so we work floor by floor or out of hours. We agree access to ceilings, risers and plant rooms with the building before we start.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

How the visit works
A visit follows the same order every time: protect the area, make the system safe, carry out the fire damper testing, tidy up and hand over the paperwork. On site, the work takes anything from a couple of hours for a handful of dampers to a full day for a large building. Loading bays, visitor permits and roof access are the first things we ask about for a site in Southfields.
- First we check the schedule and the last set of results.
- We locate every damper and note any we cannot reach.
- We test fire dampers by dropping them and smoke dampers by operating them through the controls.
- Passes are reset and any failures recorded with the reason.
- We report the results and offer remedials on failed dampers.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Clear the space around the work
- Dig out any earlier paperwork for the system

Fire damper testing around Southfields
The FSA’s food hygiene register lists about 21 schools, colleges and universities, about 50 care, childcare and hospital premises and about 3 hotels, B&Bs and guest houses with registered kitchens or food service across Southfields and its immediate surroundings (about a mile and a half). Buildings like these often have ducted ventilation, and wherever a duct crosses a fire-resisting wall or floor there should be a damper, tested at least once a year. For Southfields, the closest hospital is Royal Hospital for Neuro-disability, roughly 1 mile west. A hospital is the kind of building where dampers sit on every floor, and clinics, surgeries and care homes need the same annual testing for any they have. London buildings tend to have dampers on several floors, so testing is normally done out of hours, a zone at a time.
Wherever there are offices above shops, near Earlsfield station or elsewhere in Southfields, ductwork may cross fire-resisting floors, and any dampers need testing. School buildings such as Floreat Wandsworth Primary School are usually tested in the holidays, wherever they have dampers. The nearest hospital, Royal Hospital for Neuro-disability, is about 1 mile west; healthcare buildings like it are a reminder that dampers protect people who can’t move quickly.
Southfields is about 2 miles north-east of Wimbledon, in Greater London. Southfields gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with photos. Southfields is one of 764 towns, villages and districts in Greater London where we work for fire damper testing. London is in our area too, about 6 miles from Southfields.
Every address in SW18, SW19 and SW17 is covered for fire damper testing, from busy streets to back roads. If you need fire damper testing at premises on Burr Road, Acuba Road and Mount Road or anywhere close by, our technicians can take on the work. We also cover the places around Southfields: Earlsfield (1 mile south-east), Wandsworth (1 mile north), Summerstown (1 mile south), Battersea (2 miles north-east) and Clapham Junction (2 miles north-east).

Leave it or put it right?
Leaving damper testing for another year does not make the dampers any more likely to work. BESA guidance is to test at least annually, and a skipped year leaves a hole in your records as well. Choosing the date yourself beats having a fault choose it for you.

Southfields: your questions answered
Can you work in Southfields outside opening hours?
Yes, evening, overnight and weekend work is normal for us. It means the site in Southfields keeps running as normal. Tell us your opening hours when you ask for a quote.
Can you test school fire dampers in Southfields out of term?
Yes, and it’s the easiest time to do it. There are about 21 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Southfields. You can ring 0345 646 2711, or email photos with the dates the site is empty.
How often should fire dampers be tested?
BESA guidance is that fire dampers are tested on completion of installation and at least annually after that. Spring-operated dampers need annual testing as a minimum.
How long does fire damper testing take?
As a guide, it takes from an hour or two in a small building to several visits on a large estate. The number of dampers and how they’re reached decide the rest.
What about areas you cannot get to?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
Who has the legal duty for fire safety?
In the words of the Fire Safety Order 2005, it’s the responsible person. That is generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. If you’re not sure, check your lease and fire risk assessment.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.

What fire damper testing can’t fix
To be straight with you, there are a few things this work will not fix:
- Fire alarm or control system faults behind a smoke damper
- Designing the building’s fire compartments
- Dampers that were never installed where they’re needed
If you are not sure, just call us on 0345 646 2711 or drop us a line and we’ll give you a straight answer before you book.

- Wall and floor dampers
- Hospitals and care homes
- Riser dampers
- Fusible link fire dampers
- Offices and schools
- Motorised smoke dampers
What affects the cost of fire damper testing
You’ll get a fixed price before any work starts. It takes into account:
- Site rules, permits and inductions
- The scale of the work
- The times the site is available
- What state the system is in
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.
What to send for a quote
You do not need the technical terms. It helps if you can send:
- Any access panels or hatches you can see
- The postcode and the type of business
- The paperwork from the last visit, if you have it
- When the site is open and when it’s quiet
Want a quote for fire damper testing? Please call 0345 646 2711, or send details by email with a few details about the site. We’ll explain what we’d do and send a fixed quote before anything is booked.
Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
We also work for facilities teams across offices, schools and healthcare in Southfields and across Greater London. Work can be phased by floor, building or site to keep disruption down.
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. 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. That part needs specialist access and equipment.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
