In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
How we handle ductwork cleaning in Over Wallop
The ductwork is where an extract clean is won or lost. Sections with no way in can go uncleaned for years. We open up every reachable section and record any we can’t reach, so you know exactly where you stand. The work covers access panels, multi-storey ducts and bends and junctions, and the jobs we see most are a grease test showing the duct is overdue and ductwork that has never been cleaned.
Somewhere as small as Over Wallop, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
A written report with photos follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Aftercare tips
Once we have finished, these simple steps help:
- Keep your cleaning records together
- Keep grease filters clean and fitted whenever you cook
- Ask for a grease thickness test if the kitchen gets busier
- Leave a way through to the access panels
The report names every part of the duct that couldn’t be reached, 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 does not stop grease forming, but it stops it building unseen.
What happens on the day
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. The work itself takes a shift or more, depending on the length of the runs and the number of access points. Somewhere like Over Wallop, lanes, gates and parking are worth mentioning in advance.
- We start by working out how the duct runs and where it can be opened.
- Set points along the runs are tested for grease.
- Through the access panels, thick grease is removed by hand first.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- We test again, take pictures and note any part that couldn’t be reached.
How to prepare
- Find the previous report, if there is one
- Mention any sign-in, permit or induction we need
- Move anything stored near the system

Attenuators and discharge
Near the discharge, the air has cooled the most, so it can collect more grease than expected. It’s tested and cleaned along with the rest.
Horizontal duct runs
Flat runs of duct link the canopy to the riser or the outside wall. Grease drops out of the slowing air along them, so each section is cleaned through its access panels.
Over Wallop: your questions answered
Which fire and rescue service is responsible for Over Wallop?
It’s Hampshire and Isle of Wight Fire and Rescue Service, which covers Over Wallop. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can the work in Over Wallop be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Over Wallop needn’t be disturbed. Tell us your opening hours when you ask for a quote.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Do I get a certificate for ductwork cleaning?
When the duct is cleaned as part of a full TR19 clean, you get a TR19 certificate and a photo report. It includes readings, photos and any unreachable sections.
How long does it take to clean extract ducts?
Short runs are quick, but long or complex ducts may take several visits. We plan the work around your kitchen.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
Leave it or put it right?
There’s no law that names TR19. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, and grease in the duct is part of that. Planning a trip to Over Wallop ahead is easier for everyone than a rushed one.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
