How the job changes from site to site
Supply ductwork
Supply runs are inspected at set points first to see where cleaning is needed.
Grilles and diffusers
Every duct ends at a grille or diffuser in the room. They’re cleaned along with the ductwork, so the room side matches the duct side.
How we handle ventilation duct cleaning in Farley Green
Everyone in the building breathes the air the ventilation brings in. Keeping the ducts clean is a sensible part of looking after them, as much as clean filters and a well-kept AHU. Common call-outs are for ductwork with too few access panels to clean and blocked general extract ductwork, across hospitals and care homes, general extract ductwork and grilles and diffusers.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
What we do, step by step
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes anything from a single shift for a small office to a planned programme of nights for a large building. Seeing the system in pictures first means the trip to Farley Green can be planned properly.
- We agree timings that suit the building, including evenings and weekends.
- Access panels are opened along each run.
- We photograph the ducts, then clean each section in turn.
- We clean the grilles and diffusers and put them back.
- After photos are taken and the certificate and report issued.
Getting ready for the visit
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend
- Dig out any earlier paperwork for the system
How to get a quote
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before we start.
Related advice
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Keeping the system healthy
After the visit, a few habits help the work last:
- Include grilles in the cleaning rota
- Log every filter change
- Diary the next TR19® Air inspection
- Make sure nothing is stacked against extract grilles
Share the report with whoever looks after the building’s maintenance, so it’s all in one place. Over time, it shows how quickly the system gets dirty.
Fit access panels where the ductwork can’t be reached. Hidden sections are the ones that get worst.
What happens if it’s left?
Dust in ducts does not go away on its own. Every year adds to the job, and the more gets blown back into the rooms. Our emergency line runs 24/7, but a planned visit to Farley Green is calmer for everyone.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

FAQs for Farley Green
Do you work overnight in Farley Green?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Will you come out to Farley Green?
Yes. Farley Green is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What happens if you cannot reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Do you clean grilles and diffusers?
Yes. Where they can be removed, they’re taken down, cleaned and refitted. Fixed ones are cleaned in place.
What should I send you?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then give us a ring on 0345 646 2711, or send details by email.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
Common problems we fix in Farley Green
It matters for the people inside: dusty ducts can blow debris back into rooms, restrict airflow and make fans work harder. In hospitals, care homes and schools, clean air is especially important.
Any of these means the system needs a check-up:
- Rooms that feel airless when the system runs
- Ductwork never cleaned since it was installed
- Ventilation full of debris from building work
- Dust marks around grilles and ceiling diffusers
Ventilation work in and around Farley Green is risk-based: inspect, then clean what needs it.
