Ventilation duct cleaning for kitchens and businesses in Cowey Green
In a building in Cowey Green, the people inside spend hours breathing what the ventilation delivers. Keeping the ducts clean is a sensible part of looking after them, as much as clean filters and a well-kept AHU. The work covers general extract ductwork, offices and schools and grilles and diffusers, and the jobs we see most are extract ducts clogged with lint and dust and systems missing access panels.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Managing agents and facilities teams in Cowey Green
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Different parts, different methods
Offices and retail
Multi-let buildings may share ductwork between tenants. We plan access with the managing agent.
Grilles and diffusers
Grilles and diffusers are where the ducts meet the room. They’re cleaned along with the ductwork, so dust on them is not blown back in.
The process
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before we start, and the area around the work is covered and protected. On site, it takes anything from a single shift for a small office to a planned programme of nights for a large building. Somewhere as small as Cowey Green, the date and timings are agreed with you well before the day.
- We agree timings that suit the building, including evenings and weekends.
- We open the ductwork through its access panels.
- Before photos are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- We take after pictures and send the certificate and report.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Dig out any earlier paperwork for the system
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Cowey Green questions
Do you offer ventilation duct cleaning in Cowey Green?
Yes. Our area runs across London and the South East, Cowey Green included. You can ring 0345 646 2711 or use the quote form and tell us what needs doing.
Do you work overnight in Cowey Green?
Yes, out-of-hours work is a big part of what we do. That way a site in Cowey Green does not have to lose a day’s trading. When you call us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
What if there are not enough access panels?
Accessible sections are cleaned and the others recorded. Extra access panels can solve it, and we can fit them.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
How often should ventilation ductwork be cleaned?
Under TR19® Air, the answer comes from inspecting the ducts. Busy or sensitive buildings may need it more often.
How much notice should we give?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. Our tips:
- Tell your facilities team about dirty diffusers
- Report leaks or damp near ceilings and risers
- File each ventilation report with the building records
- Book the next inspection on the date the report recommends
You get a TR19® certificate and a photo report after the clean. Keep them in the maintenance log, with the date, location and technician recorded.
Fix leaks and damp near the ductwork quickly, as wet dust is much harder to clean.
When to call us in Cowey Green
Damp ducts hold onto dirt. Where there’s condensation or a leak, dust clings and builds faster, and it becomes harder to remove.
Keep an eye out for any of the following:
- Odours carried round the building by the ducts
- Stuffy rooms and stale air
- Dirty diffusers dropping dust into rooms
- Construction dust left in ducts after a refit
Wherever a school like St George's Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
