How we handle fire damper testing in Roxeth
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. Our job is to do the testing and hand you the paperwork that shows it. If you have dampers flagged on a fire risk assessment and buildings with no damper register, we can help.
London’s offices, hotels, hospitals and blocks of flats are full of ductwork crossing fire-resisting walls and floors. In a larger building in Roxeth, that can mean dampers on every floor, many of them above ceilings or in risers.
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.

Multi-site and managed buildings
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
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.
Different parts, different methods
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.
Smoke dampers
If a smoke damper will not operate when signalled, it goes on the report as a failure, along with what we saw.
Fire dampers in Roxeth buildings
The FSA’s food hygiene register lists about 17 schools, colleges and universities, about 61 caring premises (care homes, nurseries and hospitals) and about 4 hotels and B&Bs with registered kitchens or food service within 1.5 miles or so of the middle of Roxeth. If any of them has ducted ventilation, its dampers need an annual drop test at least. London Fire Brigade covers Roxeth. When a fire safety officer audits a non-domestic building, maintenance of systems like dampers can come up. Ceiling voids and risers in London buildings can hold many dampers, and each one has to be reached and recorded.
If you look after a building near Sudbury Hill Harrow station with a fire risk assessment due, a damper test with a full record is worth having first. Clementine Churchill Hospital, about 0.7 miles east of Roxeth, is the kind of building where dampers protect every compartment; smaller care sites need the same annual tests. If you manage a school site such as Roxeth Primary School, any fire dampers can be tested in the holidays.
Roxeth is about 1 mile south of Harrow, in Greater London. Roxeth 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 pictures. Roxeth is one of 764 places in Greater London where we work for fire damper testing. London is in our area too, about 12 miles from Roxeth.

How we price fire damper testing
A fixed price needs a few facts first. We look at:
- Travel, parking and unloading
- Working hours and out-of-hours timing
- A single visit or a regular plan
- What state the system is in
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and the price is agreed before we start.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- How we’d reach plant on a roof or in a plant room
- The postcode and the type of business
- Any previous report or certificate
- Any access panels or hatches you can see
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
What fire damper testing cannot fix
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Fire alarm or control system faults behind a smoke damper
- Designing the building’s fire compartments
- Ductwork crossing a fire wall with no damper fitted
If you’re not sure, just ring 0345 646 2711 or drop us a line and we’ll give you a straight answer before you book.
Where we work
- Motorised smoke dampers
- Hospitals and care homes
- Riser dampers
- Offices and schools
- Wall and floor dampers
- Fusible link fire dampers
What happens if it’s left?
After any fire, one of the first questions is what maintenance had been done. A damper test log helps show the responsible person kept on top of things, and you can only produce records for tests that took place. It’s better booked as a planned job in Roxeth than handled as an emergency.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.

Your questions about fire damper testing in Roxeth
Does London parking affect a job in Roxeth?
London parking can be tight, so details of loading bays and permits help. Night visits tend to make loading easier on London streets.
Can a school’s dampers in Roxeth be tested out of term time?
Yes, holiday work suits schools best. The FSA’s register shows about 17 schools and colleges with food registrations within roughly a mile and a half of Roxeth. You can call 0345 646 2711, or email photos with the dates the site is empty.
What does fire damper testing cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will normally reply within one working day.
Is a quote from pictures possible?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
How much time does a damper test visit need?
Typically the work takes from an hour or two in a small building to several visits on a large estate. It comes down mainly to how many dampers there are and how easy they are to get to.
What happens to the waste?
We take it away when we go. During the work, it’s contained so the area stays clean.
What happens on the day
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, which takes a couple of hours for a few dampers, and a day or more across a big site. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Roxeth.
- 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.
- We release each blade and check it shuts all the way.
- We reset it and record any dirt, corrosion or damage.
- Panels and tiles go back, and the results are written up.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Arrange a key holder or contact on site
Getting a quote
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, and then send you a fixed quote. To get going, call us on 0345 646 2711 or drop us a line.
Advice
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. 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.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
