How we handle fire damper testing in Pratt's Bottom
Under BESA guidance, every fire damper is tested on completion of installation and then at least once a year. Spring-operated dampers need testing every year as a minimum. We carry out fire damper testing for buildings in Pratt's Bottom and give you the records to show it’s been done. The work covers fusible link fire dampers, riser dampers and motorised smoke dampers, and the jobs we see most are smoke dampers with no recent test and damper actions from a fire risk assessment.
Damper testing in London buildings is typically planned around the people in them, so we work floor by floor or out of hours. Access to ceiling voids and risers is agreed with the building manager first.
The sign-off is always in writing: a dated report with photos 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.

Between visits
Aftercare is simple, and it makes the next visit easier:
- Never wedge or tie a damper open
- Book the next test before the year runs out
- Keep damper test reports with the fire safety log
- Don’t let hatches get painted shut or boarded over
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.
Make sure every damper can be reached. If a damper has no access panel, have one fitted before the next test.

What else we do in Pratt's Bottom
What happens if it’s left?
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. It’s far better to find that out on a test than in a fire. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

How we price fire damper testing
The diagnosis comes before the price. We look at:
- Any permits to work or inductions
- The times the site is available
- Whether it’s a one-off visit or part of a schedule
- Where the site is and how we reach it
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before any work starts.
Asking for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- The site address and the type of premises
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
To get a fixed quote, ring 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
The process
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes a few hours for a single floor, with bigger buildings phased over more than one visit. Before any visit in Pratt's Bottom, we agree where the van can stop and how equipment reaches the system.
- Before the visit, we agree access, timings and any areas with restrictions.
- Ceiling tiles and hatches are opened and each damper’s access panel removed.
- 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.
How to prepare
- Find the previous report, if there is one
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
To help us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711 or send us an email.
Advice
What fire damper testing looks like in Pratt's Bottom
Going by the FSA’s register, there are about 3 schools, colleges and universities and about 3 caring premises (care homes, nurseries and hospitals) serving food across Pratt's Bottom and its immediate surroundings (about a mile and a half). Schools, care settings and hotels are the kind of buildings where fire dampers are commonly found. Testing in London is normally done zone by zone, evenings and weekends included, so occupants aren’t disturbed. The fire and rescue service for Pratt's Bottom is London Fire Brigade. When a fire safety officer audits a non-domestic building, maintenance of systems like dampers can come up.
If you manage a historic building in the area (Down House is about 2.7 miles west), dampers fitted during conversions can be hard to reach and need recording. Wherever there are offices above shops, near Knockholt station or elsewhere in Pratt's Bottom, ductwork may cross fire-resisting floors, and any dampers need testing.

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
What we are called out for in Pratt's Bottom
Over the life of a building, owners, tenants and contractors come and go, and the damper records don’t always go with them. Without a register, nobody knows how many dampers there are or when they were last tested.
Common reasons sites call us are:
- Dampers flagged on a fire risk assessment
- Corroded dampers in damp risers and plant rooms
- Smoke dampers with no recent test
- Gaps in the fire damper test log
Healthcare buildings such as Orpington Hospital (about 1.6 miles north-west) rely on fire compartments, and the dampers in them need testing at least annually.

Common questions in Pratt's Bottom
Do you do school damper testing in Pratt's Bottom in the summer holidays?
Yes, and it’s the easiest time to do it. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Pratt's Bottom. Tell us your holiday dates and we will book the visit for when the site is empty.
What do you need to know about parking in Pratt's Bottom?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Is a quote from pictures possible?
Typically, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we typically come back within one working day. If pictures are not enough, we will survey first.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Do you look at the system first?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. A fixed quote follows.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
Do we need to close while you work?
Not usually. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages to keep things running.
What if a damper has no access panel?
It goes on the report as inaccessible, with the reason. We can fit an access panel so the damper can be tested next time.
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Larger estates can be phased building by building around the people who use them.
