Why deal with it now?
Putting it off simply moves the grease further down the duct. Fat that was soft and easy to remove hardens with heat and time, which is slower to clean. Regular cleans keep each visit shorter. Our emergency line runs 24/7, but a planned visit to Graveley is calmer for everyone.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before any work starts.

Kitchen duct cleaning in Graveley
We have been trading since 2009, cleaning kitchen extracts across the South East and London. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001 and are fully insured. The work covers vertical risers, canopies and hoods and plenums and filters, and the jobs we see most are rancid smells from grease in the duct and poor airflow at the canopy. When a restaurant in Graveley asks for duct cleaning, it’s nearly always the kitchen extract they mean, and that is exactly what we do: canopy to fan, to TR19® Grease.
What can be cleaned depends on what can be reached. Where a duct run has no panels, we say so on the report and can fit new ones.
For a kitchen in or near Graveley, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.

What we’re called out for in Graveley
What’s on the menu matters as much as how much is cooked. Fryers, grills and open flames throw much more fat into the extract than gentler cooking, so two kitchens with the same hours can need very different intervals.
Keep an eye out for any of the following:
- A smoky, hot kitchen with weak extraction
- Extraction mentioned at an environmental health visit
- Missing paperwork after a change of operator
- A system with no record of a TR19 clean
Volunteers running a hall kitchen near Church of St Mary, or anywhere in Graveley, may not know when the extract was last cleaned, and a grease test settles it.

- If the quote is a fixed price or an estimate
- What records you’ll receive afterwards

Questions from Graveley
Do you cover smaller places like Graveley?
Yes, Graveley is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Who would carry out a food hygiene inspection at a kitchen in Graveley?
Kitchens in Graveley 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.
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 accreditations do you hold?
We’re members of Vent Hygiene Elite, the scheme run by BESCA, and we clean to BESA TR19® Grease. We hold CHAS, SafeContractor and ISO 9001 too, and we’re fully insured.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Is a quote from pictures possible?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote normally follows within one working day. Some sites still need a visit, and we’ll say so.
Why do insurers care about extract cleaning?
Grease-filled ducts can carry fire well beyond the kitchen. Many policies say the extract must be cleaned to TR19, and a claim may be reduced without proof, so keep every certificate.
Which kinds of sites do you work on?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes a single shift for most kitchens, with long duct runs and tall risers needing more time. Seeing the system in pictures first means the trip to Graveley can be planned properly.
- Diagnosis comes first, with a survey of the system and how it’s reached.
- Grease readings set the baseline, and a fixed quote follows.
- We arrive after close, protect the area and contain the waste.
- Heavy deposits are scraped by hand and the system degreased to TR19® Grease.
- The sign-off: post-clean readings, a TR19 certificate and a photo report with the next clean date.
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
- Tell us where we can park and unload
Getting a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
Advice
Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

Multi-site and managed buildings
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Wipe the canopy down at the end of each day
- Wash or exchange the filters often
- Refit filters properly after cleaning
- Don’t let the canopy gutters overflow
The certificate records when the clean was done, where and by whom. File it with the fire risk assessment and the maintenance log so it’s ready when anyone asks to see it.
Wipe the canopy down regularly and empty grease troughs or collection points. It will not replace a TR19 clean, but it slows what reaches the duct.
Grease, kitchens and Graveley
The FSA’s food hygiene register shows about 8 cafés, restaurants and staff canteens and about 3 sandwich bars and takeaways within roughly a mile and a half of the centre of Graveley. Every kitchen in that count with a canopy has a full extract system, canopy to discharge, to keep clear of grease. Graveley sits within the area of Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Food hygiene inspections in Graveley are the job of North Hertfordshire council’s environmental health team. 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.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Graveley is Lister Hospital, about 0.8 miles south. If your kitchen is in a listed or historic building, like the houses around Graveley (Knebworth House is about 4.4 miles south), fitting access panels needs care.

Different parts, different methods
Schools, hospitals and care homes
Some healthcare kitchens never fully close. Cleans are planned between meals or overnight with as little disruption as possible.
Extract fan and discharge
The fan pulls the air through the whole system, and grease that gets past everything else ends up on its blades. We isolate it, open it up and degrease it.
