A vertical riser can run up several floors. Grease collects on the riser walls and gathers at the bottom as liquid grease runs down. Access along its height is needed to clean it properly.
It’s time to book a visit if you see:
- Thick deposits at the bottom of a vertical duct
- Stale grease odours from the duct
- Proof of duct cleaning for the insurer
- Fat dripping from the ductwork
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Queen Elizabeth II Hospital is the nearest hospital to Tewin, about 2.8 miles south-west.

Ductwork cleaning in Tewin
Every duct has its own route. Some run a short distance to an outside wall, others climb several floors to the roof. We map the route during the survey and finds every access point before we quote. If you have years of grease along the duct floor and sections of duct with no access panels, we can put it right.
Work in a small place like Tewin 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.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, 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.

What your team can do, and what needs us
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, and that is where we come in.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

How the visit works
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. From there, it takes a shift or more, depending on the length of the runs and the number of access points. Visits to a village like Tewin are booked in advance, at a time that suits whoever runs the site.
- First we diagnose: the route, the access and the grease levels.
- You get a fixed price before work starts.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- The duct is signed off with readings, pictures and a next clean date.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Tell us where we can park and unload
- Name a contact who can let us in at the agreed time
How to get a quote
We don’t publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To start, call 0345 646 2711, or email photos.
Advice
For landlords and multi-site operators
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Get panels fitted where the duct couldn’t be cleaned
- Report any grease dripping from duct joints
- File each certificate and photo report in the maintenance log
- Keep to the interval on the report
File the paperwork in the maintenance log. An insurer, fire officer or EHO may ask to see it, and the pictures make the duct’s condition easy to see.
Have access panels fitted where sections cannot be reached. Grease you can reach is grease that gets removed.
Fixed quotes for ductwork cleaning in Tewin
The survey tells us what the work involves. The main factors are:
- Parking and loading at the site
- The scale of the work
- How easy every part is to reach
- How many systems or sites are involved
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before we start.
Helping us quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- When the site is open and when it’s quiet
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Then ring 0345 646 2711 or drop us a line.
What ductwork cleaning can’t fix
It’s worth knowing the limits before booking:
- Leaking duct joints that need repair
- Parts of the duct with no way in
- Undersized or badly laid-out ducts
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we’ll tell you honestly before you book.

Ductwork cleaning in Tewin: the local picture
According to Food Standards Agency records, there are about 4 pubs and bars within roughly a mile and a half of the centre of Tewin. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Hertfordshire Fire and Rescue Service covers Tewin. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Kitchens in Tewin get their food hygiene inspections from East 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.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Digswell House is about 2.1 miles west), access may need planning. If you look after a school kitchen, at a school such as Ridgeway Academy or anywhere near Tewin, the holidays are the usual time for a TR19® clean.

Common questions in Tewin
Do you work overnight in Tewin?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Can a school canteen extract in Tewin be done out of term time?
Yes, holiday work suits schools best. There are about 5 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Tewin. Booking early in the term gives the best choice of holiday dates.
Where does the waste go?
We take it away at the end of the visit. While we work, it’s kept contained so the area stays clean.
Is Tewin in your area?
Yes. Tewin is part of the area we cover, as part of our area across London and the South East.
What if part of the duct can’t be reached?
Sections out of reach are written down on the report, in line with TR19. New panels can be fitted to reach them in future.
What does ductwork cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
Who is the responsible person?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
