How we handle ductwork cleaning in Nup End Green
If the ducts in Nup End Green haven’t been cleaned for a while, or nobody is sure when they were? Tell us about the system when you give us a ring on 0345 646 2711, or email photos, and we’ll send you a fixed quote for ductwork cleaning, normally within one working day. The work covers multi-storey ducts, bends and junctions and horizontal duct runs, and people most often call us about hardened, baked-on grease in long horizontal runs and duct runs with no cleaning record.
In a village or hamlet like Nup End Green, 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.
The paperwork matters as much as the work. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Common problems we fix in Nup End Green
Grease in a duct running from a kitchen in Nup End Green is as much a fire risk as in any building. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
Keep an eye out for any of the following:
- Heavy grease at the base of a riser
- Grease seeping out of the duct seams
- Thick crusts of old grease along the duct
- Proof of duct cleaning for the insurer
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Nup End Green is Lister Hospital, about 4.1 miles north.
What to look for in a quote
- If the quote is a fixed price or an estimate
- How they set the interval to the next visit
- Whether the whole system is included, or only the parts that are easy to reach
- What happens if part of the system can’t be accessed
Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Honest limits
It’s worth knowing the limits before booking:
- Leaking duct joints that need repair
- An extract fan that has stopped working
- Faulty fire dampers
If you’re not sure, just ring 0345 646 2711 or email us and we’ll give you a straight answer.
Parts of the system we cover
- Bends and junctions
- Access panels
- Multi-storey ducts
- Attenuators
- Horizontal duct runs

Landlords, agents and facilities managers
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
What affects the quote in Nup End Green
Every site gets its own quote. These are the things that affect it:
- Whether we need access equipment or extra panels
- The size of the system
- Travel, parking and unloading
- Working hours and out-of-hours timing
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, call us on 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- Photos showing the whole system and its surroundings
- The site address and the type of premises
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
For a fixed quote, call 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We normally come back within one working day.
Grease, kitchens and Nup End Green
According to Food Standards Agency records, there are about 7 pubs, bars and clubs across Nup End Green and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. In Nup End Green, food businesses are inspected by environmental health officers from North Hertfordshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked. Nup End Green is covered by Hertfordshire 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 Nup End Green (Knebworth House is about 0.6 miles north-east), fitting access panels needs care. Where a hall near Church of St Mary and St Thomas, or anywhere in Nup End Green, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

How it works
We turn up 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 floors and nearby surfaces are sheeted. On site, it takes anything from a few hours to several visits, depending on the length of duct. We agree a date with you, plan the drive to Nup End Green and turn up when the site is quiet.
- We start by working out how the duct runs and where it can be opened.
- We measure grease thickness at set points before cleaning.
- Access panels are opened and heavy deposits scraped out by hand.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- We test again, take photos and note any part that couldn’t be reached.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
- Name a contact who can let us in at the agreed time

Nup End Green questions
Who inspects food businesses in Nup End Green?
Kitchens in Nup End Green are inspected by North Hertfordshire 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.
Who enforces fire safety at workplaces in Nup End Green?
That is Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
How long does it take to clean extract ducts?
Duct length, access and grease levels all affect it. Typically it takes anything from a few hours to several visits, depending on the length of duct.
Can you fit access panels in our ductwork?
Yes. We’ll point out where panels are needed, and we can fit them so those sections are cleaned in future.
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 pictures.
Is a quote from photos possible?
Normally, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and we usually come back within one working day. If photos aren’t enough, we’ll survey first.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
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, then the readings are repeated.
How the job changes from site to site
Multi-storey and shared buildings
In a shared building, the duct links the kitchen to other spaces, which makes keeping it clean all the more important. Your certificate and report give building managers the record they need.
Bends and transitions
Transitions from the canopy spigot into the duct catch a lot of grease. We clean it from the canopy side or through a nearby panel.
