How we handle fire damper testing in Trowley Bottom
We are often asked to take on annual damper testing by the people who look after buildings in and around Trowley Bottom. Send us the damper schedule or the drawings if you have them, and we’ll plan the visit around the building’s hours. The work covers hospitals and care homes, motorised smoke dampers and offices and schools, and the jobs we see most are dampers that can’t be reached without an access panel and dirty dampers that may not close.
Testing in a small place like Trowley Bottom is planned around the journey and access, and the test itself is the same as in any city building.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes a few hours for a single floor, with bigger buildings phased over more than one visit. For a village or hamlet like Trowley Bottom, tell us about narrow lanes, gates and parking when you book.
- We gather what’s known about the dampers, from drawings, registers or past reports.
- Dampers are located one by one and reached through their access panels.
- We release each fire damper blade and operate smoke dampers from their controls.
- We reset every damper that passes and check it’s left open.
- We report on every damper, with faults and suggested remedials set out.
Getting ready for the visit

Related advice
Staff cleaning versus specialist work
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. That part needs specialist access and equipment.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
What the work involves, part by part
Access panels
Access panels sometimes get painted over, screwed shut or hidden by new ceilings. Letting us know where they are speeds the visit up.
Offices and retail
Multi-let buildings may have dampers inside tenant areas. Access to each area is planned with whoever manages the building.
Between visits
After the visit, a few habits help the work last:
- Keep the damper register up to date after any building work
- Don’t let anything obstruct a damper’s blade
- Warn anyone working in ceiling voids about the dampers
- File every damper report where your assessor can find it
If we couldn’t get to a damper, the report says so and why, for example a missing panel or a covered hatch. We can fit access panels so they can be tested next time.
The simplest way to avoid failures is to test on time, every year. Faults caught early are easier to fix.
Managing agents and facilities teams in Trowley Bottom
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.
Why act early in Trowley Bottom
A damper that’s stuck open gives fire and smoke a route straight through a fire-resisting wall. Everything else about the compartment can be right and the duct still lets it down. Testing now is how you find out before it matters. Our emergency line runs 24/7, but a planned visit to Trowley Bottom is calmer for everyone.
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and the price is agreed before any work starts.

What’s TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.

We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
Who is the responsible person?
The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
Do you certify fire dampers?
We test, record and report, rather than certify dampers to a standard. It lists each damper, the result and any remedials needed.
