How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes from a few hours to more than one visit, depending on duct length and access. Visits to a village like Thundridge are booked in advance, at a time that suits whoever runs the site.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- Each section is cleaned in turn through its access 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.
How to prepare
- Mention any parking or loading restrictions
- Name a contact who can let us in at the agreed time
- Find the previous report, if there is one
Getting a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.

About our ductwork cleaning in Thundridge
Grease in a duct is hidden, which is exactly why it’s dangerous. A flare-up drawn up from the range can light it, and fire can then run along the ductwork to other parts of the building. Cleaning the duct takes that fuel away. If you have an insurer asking for TR19 evidence and years of grease along the duct floor, we can help.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Access panels
Panels have to seal properly once they’re closed so the duct stays tight. We’ll tell you if any panel needs replacing.
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.
Between visits
How long the results last depends on use and care. We suggest:
- Run the extract fan throughout service
- Check readings when the menu changes
- Report any grease dripping from duct joints
- Keep access panels clear of stored items
File the paperwork in the maintenance log. It’s the evidence an insurer or inspector may ask for, and the photos make the duct’s condition easy to see.
Have access panels fitted where sections cannot be reached. It doesn’t stop grease forming, but it stops it building unseen.
Leave it or put it right?
There’s no law that names TR19. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, including the grease inside the extract ductwork. Planning a trip to Thundridge ahead is easier for everyone than a rushed one.
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 work begins.

What affects the cost of ductwork cleaning
A fixed price needs a few facts first. We check:
- When the work can happen, such as evenings, overnight or weekends
- Whether we need access equipment or extra panels
- The condition we find in the survey
- One-off work versus a regular cycle
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and the price is agreed before we start.
Asking for a quote
Many jobs can be priced from photos and some basics. Useful things to send:
- When the site is open and when it’s quiet
- Any symptoms, from odd noises to smells or leaks
- Close-ups of filters, grilles, hatches or access panels
- The site address and the type of premises

Kitchen extracts in Thundridge
The FSA’s food hygiene register includes about 3 bars, pubs and nightclubs and about 3 hotels and B&Bs within roughly a mile and a half of the centre of Thundridge. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Food hygiene inspections in Thundridge are the job of East Hertfordshire council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Hertfordshire Fire and Rescue Service covers Thundridge. 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.
If you run a church or community hall kitchen, near Parish Church of St Mary or elsewhere in Thundridge, its extract still collects grease from every lunch and event. If your kitchen is in a listed or historic building, like the houses around Thundridge (Much Hadham Palace is about 4.8 miles east), fitting access panels needs care. Term dates shape school work: for a school like Thundridge Church of England Primary School, an extract clean fits neatly into a half-term or summer break.

FAQs for Thundridge
Who enforces fire safety at workplaces in Thundridge?
It’s Hertfordshire Fire and Rescue Service, which covers Thundridge. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Can you get to a site in Thundridge?
Yes. Thundridge is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Do you have insurance?
Yes. We are fully insured, and we can share the details when you need them.
Can one contract cover all our sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it doesn’t spread.
What about areas you cannot get to?
We record them on the report, with pictures where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
How is kitchen extract ductwork cleaned?
Each section is cleaned through its own panel. Heavy grease comes out by hand, and what’s left is degreased, with readings taken before and after.
What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
When something else is needed
A few issues sit outside what this work can do:
- Parts of the duct with no way in
- An extract fan that has stopped working
- A duct that is too small or badly routed for the kitchen (a design issue)
If you’re not sure, just give us a ring on 0345 646 2711 or drop us a line and we will give you a straight answer.
