For TR19 Air cleaning of general supply and extract ventilation ductwork in commercial buildings in Farningham, one call is all it takes, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.

- Poor airflow from the vents
- Duct runs that can’t be reached for cleaning
Different parts, different methods
Hospitals and care homes
People in hospitals and care homes can be more vulnerable to poor air. Inspection-led cleaning under TR19® Air helps keep systems in good condition.
Extract ductwork
Extract fans pull air through these ducts, so a blocked duct strains them. Clearing the duct helps the fan do its job.
How we handle ventilation duct cleaning in Farningham
Ductwork is reached through access panels along each run. Where there aren’t enough panels to reach every section, we note the uncleaned parts in the report, and we can fit new panels so they’re covered next time. We’re often asked to deal with dust marks around grilles and ceiling diffusers and dusty supply ductwork that hasn’t been cleaned in years, across toilet extract systems, supply ductwork and general extract ductwork.
For a building in or near Farningham, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Every visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

How it works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes a day or less for a small system and a series of visits for a large one, and we clear up before we go. For a village or hamlet like Farningham, tell us about narrow lanes, gates and parking when you book.
- First we plan when the work can happen, often out of hours.
- Access panels are opened along each run.
- Before pictures are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- After pictures are taken and the certificate and report issued.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Arrange a key holder or contact on site
- Find the previous report, if there is one
Ask for a quote
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To get going, call us on 0345 646 2711, or email photos.

Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Do not run the ventilation while builders are sanding or cutting
- Report leaks or damp near ceilings and risers
- Keep filters changed on time
- Store cleaning certificates where auditors can find them
The report includes a recommended date for the next inspection, in line with the risk-based approach of TR19® Air. Put it in the diary now so it is not missed.
Good filter maintenance protects the ductwork. Overdue or badly fitted filters let dust into the supply ducts.

Common questions in Farningham
Do you work overnight in Farningham?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Can you do ventilation duct cleaning in Farningham?
Yes, Farningham is covered. You can call 0345 646 2711 or email us and tell us what needs doing.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Will we have paperwork to show the system was cleaned?
Yes, a TR19® certificate and photos. It also notes unreached sections and a recommended next inspection.
What is TR19® Air?
TR19® Air is the part of BESA’s TR19® that covers general supply and extract ventilation, beyond the kitchen. It’s risk-based and led by inspection, and kitchen extract falls under TR19® Grease.
What happens if you cannot reach some of it?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.

What else we do in Farningham
Do you need ventilation duct cleaning in Farningham?
Why does it matter?: dirt in the ducts can come back out of the grilles, slow the air and add strain on fans. In hospitals, care homes and schools, clean air is especially important.
These are the problems we see most often:
- Ventilation full of debris from building work
- Ductwork never cleaned since it was installed
- Systems missing access panels
- Damp or stale smells from grilles
If you manage a school such as The Anthony Roper Primary School, ventilation cleaning is best booked for the holidays.
Questions to ask before you book
- If the quote is a fixed price or an estimate
- Whether inaccessible sections are listed on the report
- How they set the interval to the next visit
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
What your team can do, and what needs us
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.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
