How we handle ductwork cleaning in Richmond upon Thames
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Every horizontal run and vertical riser collects grease along the way, and that is where a kitchen fire can travel. We clean it from the inside, through access panels, to BESA TR19® Grease. If you are dealing with hardened, baked-on grease in long horizontal runs and proof of duct cleaning for the insurer, we can help.
London kitchens tend to trade late and open early, so work in Richmond upon Thames is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Between visits
Here’s the after-treatment advice, in brief:
- Flag drips from the duct straight away
- Run the extract fan throughout service
- Keep your cleaning records together
- Ask us about extra access panels where sections cannot be reached
Any section of duct we couldn’t reach is listed on the report and why. We can fit access panels so those sections are cleaned next time.
Keep to the cleaning interval on the report. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.

What ductwork cleaning looks like in Richmond upon Thames
The FSA’s data shows about 45 pubs and bars and about 8 hotels, B&Bs and guest houses registered within 1.5 miles or so of the middle of Richmond upon Thames. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Environmental health officers from Richmond-Upon-Thames council inspect food businesses in Richmond upon Thames. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
Where a hall near Holy Trinity Richmond, or anywhere in Richmond upon Thames, hosts lunch clubs or events, its extract gathers grease just as a café’s does. School kitchens, at schools like Marshgate Primary School for example, are typically cleaned in the holidays so no lunches are lost. If you cook for passing trade around Richmond station, the extract can be cleaned between your last and first customer.

How the job changes from site to site
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.
Access panels
Extra panels can be installed where there are gaps, so the next clean reaches more of the system. The survey shows where they’re needed.
In-house cleaning or a specialist?
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
In-house cleaning and specialist cleaning do different jobs. 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. That part needs specialist access and equipment.
The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a shift or more, depending on the length of the runs and the number of access points. In Richmond upon Thames, as across London, we typically work overnight or at weekends and hand the site back ready to open.
- 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.
- 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
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us about site rules, permits or sign-in
- Plan for cooking equipment or plant to be off before we arrive
How to get a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before any work starts.
Advice
Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Leave it or put it right?
Fire inside a duct is out of sight and out of reach. It can travel through the ductwork to other parts of the building, so cleaning the duct is as important as cleaning the hood. A booked night’s work in Richmond upon Thames costs you no trading time; an unplanned closure does.
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711 or send us an email, and we’ll explain what it covers.

FAQs for Richmond upon Thames
Who is the fire and rescue service for Richmond upon Thames?
That is London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Do you work at weekends in Richmond upon Thames?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Richmond upon Thames needn’t be disturbed. Just call us on 0345 646 2711 or use the quote form with your opening times and we will plan around them.
How can I tell if my extract ducts are dirty?
We measure it. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). A mean above 200 microns, or 500 microns at any point, means it’s due.
What happens if you cannot reach some of it?
Anything we can’t reach goes on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
Do we need to close while you work?
Not normally. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages so parts stay in use.
Do you install duct access panels?
Yes, extra panels can be fitted. That lets the next clean reach sections that were missed, and the report will show where they’re needed.
Is TR19 cleaning required by law?
No. TR19® itself is not law; it’s a BESA specification. 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.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
