Fire damper testing in Netherne on-the-Hill
The idea behind drop testing is straightforward: the blade is released, checked for a full close and reset. We test dampers for sites in Netherne on-the-Hill and the rest of Greater London, logging each one so the record builds year on year. Common call-outs are for buildings with no damper register and dampers that stick or won’t close fully, across riser dampers, wall and floor dampers and offices and schools.
Many London buildings have been through several fit-outs, and dampers can end up hidden above new ceilings with no access panel. In Netherne on-the-Hill, as across London, finding every damper and recording its access is part of the job.
Each visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What we’re called out for in Netherne on-the-Hill
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has a duty to keep fire safety measures working, and dampers are part of those measures. Whoever that is, whether employer, owner, landlord, facilities manager or managing agent, needs to be able to show the dampers work.
Keep an eye out for these warning signs:
- Smoke dampers that need testing through their controls
- Fire dampers that haven’t been tested for over a year
- Damper actions from a fire risk assessment
- Missing or out-of-date damper records
Hospitals such as St Lawrence's Hospital, about 1.9 miles east, are a good example of buildings with dampers on many floors; if you manage a clinic, surgery or care home near Netherne on-the-Hill, the same annual testing applies.

Netherne on-the-Hill: your questions answered
Is parking a problem for work in Netherne on-the-Hill?
A loading bay, a visitor permit or off-street space near the site in Netherne on-the-Hill makes the visit easier to plan. Much of our London work is done overnight, which helps.
Can the work in Netherne on-the-Hill be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. It means the site in Netherne on-the-Hill keeps running as normal. Tell us your opening hours when you ask for a quote.
Do we lose a day’s trading?
Not usually. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we’re fully insured.
Does the law say we must follow TR19?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and without records, many insurers may refuse or reduce a claim.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What happens if a damper fails its test?
We record the damper as failed, with the reason, whether that’s a stuck blade, rust or a damaged link. Remedials are offered, either a repair or a replacement damper, and test it again afterwards.
How much time does a damper test visit need?
Testing takes a morning or an afternoon for a small number of dampers, longer where there are many. Large buildings can be split over several visits, and you can give us a ring on 0345 646 2711 or drop us a line to talk it through.
Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Book the next test before the year runs out
- Keep ceiling hatches and duct panels easy to open
- Act on failed dampers rather than leaving them on file
- Report leaks or condensation near ductwork quickly
Make sure trades working in ceilings and risers know where the dampers sit, and that they mustn’t tie, wedge or obstruct them. Anything they disturb should be checked again.
Make sure every damper can be reached. If a damper has no access panel, have one fitted ahead of the next visit.

What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
Part by part
Offices and retail
In shared buildings, some dampers sit inside tenants’ space. Access to each area is planned with whoever manages the building.
Schools, hospitals and care homes
Schools are often easiest to test during the holidays, when ceilings can be opened without disturbing lessons.
