Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
How we handle ductwork cleaning in How Green
Each extract duct we take on in How Green goes through the full routine: readings at set points, heavy grease scraped out by hand, then degreasing to suit the deposit. Readings are taken again afterwards and photos go into your report. If you are dealing with readings above 200 microns from a grease thickness test and smells of old cooking grease from the ductwork, we can put it right.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

How Green: your questions answered
Do you work overnight in How Green?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Which council inspects kitchens in How Green?
Kitchens in How Green are inspected by Sevenoaks council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can you clean ductwork with no access panels?
Ductwork needs access to be cleaned. Those parts are listed, and we can install panels so they’re reached next time.
What paperwork do you give after a duct clean?
Every clean comes with a photo report, plus a TR19 certificate when the whole system is cleaned. File them with the fire risk assessment.
Do you install duct access panels?
Yes. We will point out where panels are needed, and fitting them means future cleans are more complete.
How much does ductwork cleaning cost in How Green?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What’s involved in cleaning extract ducts?
After a survey and grease readings, the duct is opened up through its access panels. Each run and riser is scraped and degreased, and test again when we’re done.
Honest limits
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Fire dampers that do not close (they need testing and remedials)
- Duct sections that need replacing
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we will tell you honestly before you book.
What the work covers
- Access panels
- Bends and junctions
- Multi-storey ducts
- Attenuators
- Vertical risers
- Horizontal duct runs
Managing agents and facilities teams in How Green
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes anything from a few hours to several visits, depending on the length of duct. In a small place like How Green, the journey is planned ahead and the visit arranged around the site’s hours.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Heavy deposits come out by hand, then each section is degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Before we arrive
- Dig out any earlier paperwork for the system
- Move anything stored near the system
- Let us know about parking and loading

Common problems we fix in How Green
A vertical riser can run up several floors. Grease collects on the riser walls and gathers at the bottom, where it can pool. Access along its height is needed to clean it properly.
Common reasons sites call us are:
- Hardened, baked-on grease in long horizontal runs
- A duct clean needed for an insurer
- Grease seeping out of the duct seams
- Duct runs with no cleaning record
Volunteers running a hall kitchen near Church of St Peter, or anywhere in How Green, may not know when the extract was last cleaned, and a grease test settles it.

Grease, kitchens and How Green
The FSA’s food hygiene register shows about 4 restaurants, cafés and canteens within roughly a mile and a half of the centre of How Green. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. In How Green, food businesses are inspected by environmental health officers from Sevenoaks council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand. How Green sits within the area of Kent Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If your kitchen is in a listed or historic building, like the houses around How Green (Hever Castle is about 0.7 miles south), fitting access panels needs care. Bursars and site managers at schools such as Hever Church of England Voluntary Aided Primary School tend to book extract cleaning for when the kitchen is empty.

Part by part
Vertical risers
A riser takes the duct up through one or more floors. Grease collects on the walls and at the foot of the riser, so the base is one of our test points.
Access panels
We can fit new access panels where the duct needs them, making future cleans more complete. We will recommend where they should go.
