Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
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, which is where we come in.
About our ductwork cleaning in Langley Bottom
If the ducts in Langley Bottom haven’t been cleaned for a while, or nobody is sure when they were? A few details about the system are a good start when you call 0345 646 2711 or drop us a line, and a fixed price will follow, typically within one working day. The work covers attenuators, vertical risers and bends and junctions, and the jobs we see most are a grease test showing the duct is overdue and fat dripping from the ductwork.
In a village or hamlet like Langley Bottom, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Grease, kitchens and Langley Bottom
The FSA’s data shows about 8 pubs and bars registered in Langley Bottom and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Fire safety in Langley Bottom falls to Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Environmental health officers from North Hertfordshire council inspect food businesses in Langley Bottom. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.
A hospital like Lister Hospital, about 2.4 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Bursars and site managers at schools such as The Thomas Alleyne School tend to book extract cleaning for when the kitchen is empty.

Signs you need ductwork cleaning in Langley Bottom
The further the air travels from the cooking, the cooler it gets. Cooling air drops its grease onto the inside of the duct, so duct runs keep collecting grease long after the canopy.
It’s time to book a visit if you see:
- Thick crusts of old grease along the duct
- An insurer asking for TR19 evidence
- Sections of duct with no access panels
- Fat dripping from the ductwork
If your kitchen is in a listed or historic building, like the houses around Langley Bottom (Knebworth House is about 1.8 miles south-east), fitting access panels needs care.
What your quote should include
- Proof of insurance
- Whether they recommend a next date
- Which accreditations they hold, and whether you can check them
- Whether the price is fixed
What affects the quote in Langley Bottom
A fixed price needs a few facts first. We check:
- A single visit or a regular plan
- The condition we find in the survey
- The number of sites or systems
- How easy every part is to reach
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.
What to send for a quote
When you call or email, these details help:
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
- How we’d reach plant on a roof or in a plant room
For a fixed quote, give us a ring on 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
What happens if it’s left?
Grease narrows the duct and slows the air. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy and grease can drip from duct joints. It’s simpler to plan the work at Langley Bottom now than to arrange it in a hurry later.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.

What a clean won’t put right
It’s worth knowing the limits before booking:
- Fire dampers that don’t close (they need testing and remedials)
- An extract fan that has stopped working
- Duct sealed behind fixed ceilings or walls
If you’re not sure, just phone us on 0345 646 2711, or email photos and we’ll give you a straight answer.
Parts of the system we cover
- Access panels
- Vertical risers
- Horizontal duct runs
- Attenuators
- Bends and junctions
- Multi-storey ducts
What the work involves, part by part
Attenuators and discharge
The last section of duct before the discharge is often the coolest, so it can collect more grease than expected. It’s tested and cleaned along with the rest.
Vertical risers
Cleaning a riser needs access along its height. Where it can’t be reached safely, the report says so.
How it works
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a shift or more, depending on the length of the runs and the number of access points, and the area is cleaned down before we leave. Visits to a village like Langley Bottom are booked in advance, at a time that suits whoever runs the site.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Getting ready for the visit
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards
- Make sure equipment near the work can be switched off and left to cool

FAQs for Langley Bottom
Which fire authority looks after Langley Bottom?
Fire safety enforcement in Langley Bottom is handled by Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Which environmental health team covers Langley Bottom?
That’s North Hertfordshire council, whose environmental health officers carry out food hygiene inspections in Langley Bottom. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Do you have a 24/7 line?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What information do you need?
Some pictures and a quick description of the system plus the address and your hours. If we need more, we will ask.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
What shows that the ducts need a clean?
Start with the date of the last clean. If it’s overdue, or there isn’t one, a clean is due, and grease readings will confirm how urgent it is.
Do we have to stop cooking while the ducts are cleaned?
When the kitchen is closed. Long ducts can be split across visits, with the kitchen ready to cook each morning.
