Hertfordshire · Ductwork cleaning
Ductwork cleaning in Bengeo, Hertfordshire
One call covers cleaning of kitchen extract ductwork, horizontal runs and vertical risers through access panels in Bengeo, from survey to sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Heavy grease at the base of a riser
- An insurer asking for TR19 evidence
- Duct runs that can’t be reached
What we’re called out for in Bengeo
Slow air leaves the most grease behind. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
If you notice any of these, it’s worth a diagnosis:
- A grease test showing the duct is overdue
- An insurer asking for TR19 evidence
- Thick crusts of old grease along the duct
- Grease seeping out of the duct seams
Term dates shape school work: for a school like Mill Mead Primary School, an extract clean fits neatly into a half-term or summer break.
Before you book anyone
- What paperwork you get at the end
- Whether the quote shows VAT
- Proof of accreditation you can verify
- Whether the figure could change on the day
Ductwork cleaning in Bengeo
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, with each certificate issued through the BESCA portal. If you’re dealing with proof of duct cleaning for the insurer and a grease test showing the duct is overdue, we can put it right.
Kitchens around a place like Bengeo are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Why act early in Bengeo
Old grease in a duct for a kitchen in Bengeo doesn’t stay soft. It bakes into a hard layer that takes far longer to remove, so the later the clean, the bigger the job. Even a site near Bengeo that is only busy part of the week needs its system checked on a schedule.
The cost depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.
Why Bengeo businesses choose us
- Ventilation hygiene specialists since 2009
- Fully insured
- Every job surveyed first

How we price ductwork cleaning
The survey tells us what the work involves. The main factors are:
- Access, including roofs, risers and ceiling voids
- Travel, parking and unloading
- Site rules, permits and inductions
- The condition we find in the survey
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
What we need to know
What to send for a quote:
- The postcode and the type of business
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
- The roof, plant room or outside wall the system runs to

What happens on the day
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes anything from a few hours to several visits, depending on the length of duct. Tell us about any gates, ladders or locked plant areas at your site near Bengeo when you book.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.

Advice
Managing agents and facilities teams in Bengeo
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 pictures.
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
What ductwork cleaning looks like in Bengeo
According to Food Standards Agency records, there are about 30 bars, pubs and nightclubs and about 3 hotels and B&Bs in Bengeo 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. In Bengeo, food businesses are inspected by environmental health officers from East Hertfordshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Bengeo falls to 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 cook for passing trade around Hertford East station, the extract can be cleaned between your last and first customer. If you run catering at a healthcare site, such as a hospital like Hertford County Hospital about 0.7 miles south-west, the extract may need cleaning more often than a part-time kitchen.

Questions from Bengeo
Can the work in Bengeo be done at night or at weekends?
Yes, we can come after you close and finish before you open. The work in Bengeo can fit around your hours. Tell us your opening hours when you ask for a quote.
Do you work in villages like Bengeo?
Yes, we work in villages as well as towns, and Bengeo is covered. Photos of the system and directions to the site help us plan the visit.
Who is the responsible person?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
Are you fully insured?
Yes. We’re fully insured, and we can share the details when you need them.
Can you clean ductwork with no access panels?
We clean everything we can reach and record what we cannot. Extra panels can be installed, and we can do that for you.
How can I tell if my extract ducts are dirty?
We measure it. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. A mean above 200 microns, or 500 microns at any point, means it’s due.
How often does extract ductwork need cleaning?
It follows the same interval as the whole extract, ranging from 3-monthly to 12-monthly. Grease thickness testing shows whether that’s often enough.
Will I get a report after the ducts are cleaned?
Readings, photos and, for a full clean, a TR19 certificate. The report says when the next clean is due.
What the work involves, part by part
Bends and transitions
Bends, elbows and changes of size are where grease collects most. The air slows and drops its load, so we clean these points carefully.
Vertical risers
Risers carry the extract up through the building to the roof. Grease runs down the walls and gathers at the base, so the base is one of our test points.
