Ductwork cleaning for kitchens and businesses in High Cross
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Grease settles along every metre of it, and that’s where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. The work covers vertical risers, attenuators and multi-storey ducts, and people most often call us about a duct nobody has opened in years and a duct clean needed for an insurer.
Work in a small place like High Cross starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

The process
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the ductwork cleaning, tidy up and leave you the report. On site, the work takes anything from a few hours to several visits, depending on the length of duct. For a village or hamlet like High Cross, tell us about narrow lanes, gates and parking when you book.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, photos and a next clean date.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Dig out any earlier paperwork for the system
- Mention any sign-in, permit or induction we need
Get a fixed quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

High Cross: your questions answered
Can the work in High Cross be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in High Cross keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Which environmental health team covers High Cross?
Food hygiene inspections in High Cross are carried out by East Hertfordshire council. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Are you accredited?
We are 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.
Do you work in High Cross?

Do I get a certificate for ductwork cleaning?
A full system clean comes with a TR19 certificate and a photo report. The report shows readings, photos and any sections we couldn’t reach.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
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.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
Ductwork cleaning around High Cross
Kitchens in High Cross get their food hygiene inspections from East Hertfordshire council. 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. The fire and rescue service for High Cross is Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you look after a school kitchen, at a school such as Thundridge Church of England Primary School or anywhere near High Cross, the holidays are the usual time for a TR19® clean. Volunteers running a hall kitchen near Church of St John the Evangelist, or anywhere in High Cross, may not know when the extract was last cleaned, and a grease test settles it.

What a clean won’t put right
A few issues sit outside what this work can do:
- A duct that is too small or badly routed for the kitchen (a design issue)
- A worn-out fan that needs replacing
- Leaking duct joints that need repair
If in doubt, ring 0345 646 2711 or use the quote form and we will say what we think before booking.
Where we work
- Bends and junctions
- Attenuators
- Horizontal duct runs
- Multi-storey ducts
- Vertical risers
- Access panels
Aftercare tips
A little care between visits keeps the system in better shape. We recommend:
- Diarise the next duct clean
- Report any grease dripping from duct joints
- Make sure filters are seated properly
- Don’t block access panels with shelving or stock
Any section of duct we couldn’t reach is listed on the report, with the reason. We can fit access panels so those sections are cleaned next time.
Extra access panels mean more of the duct gets cleaned each time. It doesn’t stop grease forming, but it stops it building unseen.
Signs you need ductwork cleaning in High Cross
A greasy duct is a fire path, in High Cross as anywhere. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
If you notice any of these, it’s worth a diagnosis:
- A grease test showing the duct is overdue
- Proof of duct cleaning for the insurer
- Hardened, baked-on grease in long horizontal runs
- Grease seeping out of the duct seams
If your kitchen is in a listed or historic building, like the houses around High Cross (Much Hadham Palace is about 4.2 miles east), fitting access panels needs care.
Questions to ask before you book
- Whether the price is fixed
- What’s included in the scope, part by part
- How they set the interval to the next visit
- Proof of insurance
Part by part
Bends and transitions
The join where the canopy meets the duct is a common hotspot. We clean it from the canopy side or through a nearby panel.
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.

Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
What your team can do, and what needs us
Staff cleaning and specialist work aren’t 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. That part needs specialist access and equipment.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
