08:30 Who we are
Clean Ducts has spent a decade keeping commercial and industrial ventilation clean, safe and compliant — ductwork, kitchen extract, fire dampers, AHUs, clean rooms. Many of our supervisors and engineers have over 30 years in the ventilation industry.
Behind the brand is Gemini AMPM Ltd — the employee-owned fire and security firm that has protected the South East’s most demanding buildings since 1997. Clean Ducts is its ventilation-hygiene arm: same engineers’ culture, same evidence-first standard, same group answerable for the result.
11:00 The standard
Every clean to BESA’s Guide to Good Practice — TR19 for ventilation hygiene, TR19 Grease for kitchen extract. Deposits measured, results certificated.
Vent Hygiene Associate member of BESCA — our work is independently verified, not self-declared.
Live accreditations held across AMPM Group — BAFE, NSI Gold, FIRAS, CHAS, Constructionline, SafeContractor and more, each verifiable on its register.
14:00 How we run a job
Free survey. We walk the system, measure what’s there and tell you what the regulations actually require.
A written scope with transparent pricing — frequency set by the evidence, not by a sales target.
Worked around your operation — nights, weekends, term breaks — by directly employed engineers.
Photographs, measurements, test results and certificates — filed and in your inbox before we leave site.
19:00 The group
The day shift — MEPH, commercial fit-out, fabric and groundworks across London and the South East.
The night watch — fire, security, gas suppression and passive fire. Est. 1997, employee-owned, our parent company.
The air shift — the loop that never stops. Ventilation hygiene, grease, dampers and ductwork, cleaned, tested, certificated.
