Ductwork cleaning in Greenhill
The ductwork is where an extract clean is won or lost. Without enough access panels, long stretches can go years without being touched. Each section we can reach is cleaned, and any we cannot is written down, so you know exactly where you stand. Typical jobs include duct runs that can’t be reached and grease pooling at the foot of the riser, across bends and junctions, vertical risers and attenuators.
In London, few kitchens can spare a day to close, so work in Greenhill is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
The paperwork matters as much as the work. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What happens on the day
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Getting kit into a London building takes planning, so let us know where we can load and park in Greenhill.
- First we diagnose: the route, the access and the grease levels.
- You get a fixed price before work starts.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, pictures and a recommended next clean date complete the job.
How to prepare
- Have your last certificate or report to hand
- Arrange a key holder or contact on site
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote

Advice
What ductwork cleaning looks like in Greenhill
The FSA’s food hygiene register includes about 83 bars, pubs and nightclubs and about 23 hotels, B&Bs and guest houses within roughly a mile and a half of the centre of Greenhill. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. In Greenhill, food businesses are inspected by environmental health officers from Camden council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after. London jobs normally start after the last service, with loading and roof access agreed with the building first.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; New End Hospital is the nearest hospital to Greenhill, about within half a mile north-west. Bursars and site managers at schools such as The Royal School tend to book extract cleaning for when the kitchen is empty.

Do you need ductwork cleaning in Greenhill?
Damaged or poorly fitted filters let more grease into the duct. More grease reaches the ductwork than it should and it fills faster.
Look out for any of the following:
- Hardened, baked-on grease in long horizontal runs
- Grease seeping out of the duct seams
- Grease pooling at the foot of the riser
- Duct runs with no cleaning record
For kitchens close to Hampstead Heath station, where the day often starts early and ends late, the extract can be cleaned overnight.
Comparing quotes
- Whether they’re fully insured
- If the quote is a fixed price or an estimate
- How areas they cannot reach will be recorded
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
What happens if it’s left?
BESA guidance says grease shouldn’t exceed a mean of 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean straight away. Putting off the clean only pushes readings higher. Leaving it on a busy London site only adds to the work.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

FAQs for Greenhill
Is parking a problem for work in Greenhill?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Do you do school kitchen extract cleaning in Greenhill in the summer holidays?
Yes, out-of-term visits are normal for schools. There are about 69 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Greenhill. Send us your term dates when you ring 0345 646 2711 or use the quote form, and we’ll fit the work in.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What information do you need?
Some photos and a quick description of the system plus the address and your hours. We’ll ask for anything else we need.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
Do I get a certificate for ductwork cleaning?
You get a photo report with before and after pictures, and a full TR19 clean also comes with a certificate issued through the BESCA Vent Hygiene Elite portal. Keep both in the maintenance log.
Do we have to stop cooking while the ducts are cleaned?
Only while we are working, and we work around you. Most kitchens book overnight or weekend cleans, so no service is lost.
Are you insured?
Yes, we are fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.

What staff can safely do
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Between visits
Here’s the after-treatment advice, short and simple:
- Get panels fitted where the duct couldn’t be cleaned
- Tell us if grease leaks from the ductwork
- Book the next clean before the recommended date
- Leave a way through to the access panels
You’ll have a recommended date for the next clean, based on the readings and your daily cooking hours, in line with BESA guidance.
Extra access panels mean more of the duct gets cleaned each time. Grease you can reach is grease that gets removed.
What the work involves, part by part
Bends and transitions
The join where the canopy meets the duct is a common hotspot. We reach it from the plenum side where possible.
Attenuators and discharge
Near the discharge, the air has cooled the most, so it can collect more grease than expected. We include it in the clean and the readings.
