For landlords and multi-site operators
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Fire damper testing in High Barnet, done properly
The idea behind drop testing is straightforward: the blade is released, checked for a full close and reset. We do this for buildings in High Barnet and across Greater London, logging each one so the record builds year on year. The work covers fusible link fire dampers, offices and schools and hospitals and care homes, and the jobs we see most are dampers clogged with dust or grease and fire damper items raised by an assessor.
Many London buildings have been through several fit-outs, and dampers can end up hidden above new ceilings with no access panel. Locating each damper in a building in High Barnet is the first part of a proper test.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Diary the annual test well ahead
- Keep cables and fixings away from damper blades
- Close off damper faults promptly
- Add new dampers to the register as they’re fitted
The next test should be no more than a year away. The guidance is at least once a year, and booking the same month each year keeps it simple.
Make sure every damper can be reached. If a damper has no access panel, have one fitted ahead of the next visit.
Fire dampers in High Barnet buildings
Food Standards Agency data includes about 21 schools, colleges and universities and about 26 caring premises (care homes, nurseries and hospitals) in and around High Barnet, up to about a mile and a half out. If any of them has ducted ventilation, its dampers need an annual drop test at least. About 0.5 miles south-west of High Barnet is Barnet General Hospital, the nearest hospital. Where patients or residents may need help to leave a building, working dampers matter all the more. High Barnet is covered by London Fire Brigade. In most workplaces and other non-domestic buildings, it’s the fire and rescue authority that enforces the Fire Safety Order.
Site managers at schools such as Foulds School usually find the summer break the easiest time for ceiling work like damper testing. The nearest hospital, Barnet General Hospital, is about 0.5 miles south-west; healthcare buildings like it are a reminder that dampers protect people who can’t move quickly.

What else we do in High Barnet
High Barnet questions
Can you work in High Barnet outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The work in High Barnet can fit around your hours. Tell us your opening hours when you ask for a quote.
Which fire and rescue service is responsible for High Barnet?
Fire safety enforcement in High Barnet is handled by London Fire Brigade. A report listing every damper, its location and its result is the easiest way to show the dampers are maintained.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Do you carry out smoke damper testing?
Yes. We test smoke dampers through their control system, as they’re motor driven. We check every blade moves fully and record the outcome.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How much does fire damper testing cost?
It depends on the site, so we quote each one individually. To get one, ring 0345 646 2711 or drop us a line with the site type, opening hours and a few photos.
How often does BESA say fire dampers should be tested?
At least once a year, under BESA guidance, plus a test when the damper is first installed. Your fire risk assessment may call for some dampers to be tested more often.
Common problems we fix in High Barnet
Links and springs age like any other part. Damaged or painted links and weak springs mean the blade may stop short, which only shows up when the damper is dropped.
It’s time to book a visit if you see:
- Dampers flagged on a fire risk assessment
- Dampers that stick or won’t close fully
- Motorised smoke dampers due for testing
- Fire dampers nobody can get to
Historic buildings that have had ventilation added later can hide dampers in awkward places; Wyllyotts Manor, about 2.9 miles north, is one of the historic houses in the area around High Barnet.
What to look for in a quote
- How areas they cannot reach will be recorded
- Whether they recommend a next date
- Which accreditations they hold, and whether you can check them
- Whether the price is fixed
What happens if it’s left?
After any fire, one of the first questions is what maintenance had been done. Damper test records are part of that answer, and you can only produce records for tests that took place. A building in High Barnet may have flats or offices above and alongside, and a fault in the system can affect them too.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.

What the work involves, part by part
Fusible link fire dampers
For dampers closed by a spring, BESA guidance is annual testing as a minimum. Dropping the blade reveals springs that are tired and blades that drag.
Ceiling voids and risers
Plant rooms and risers can be damp, which leads to corrosion. We note any rust or water damage on the report so it can be dealt with.
How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Loading bays, visitor permits and roof access are the first things we ask about for a site in High Barnet.
- We go through the damper schedule and any previous faults.
- 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.
- The report sets out the results, and we can quote to repair or replace failed dampers.
Before we arrive
- Arrange a key holder or contact on site
- Dig out any earlier paperwork for the system
- Clear the space around the work

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
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.
