Ductwork cleaning for kitchens and businesses in Richmond
We treat ductwork like a doctor treats arteries: diagnose where grease has built up, clear it and confirm the result. Grease readings before and after give you the evidence, alongside before and after pictures. If you are dealing with grease leaking from duct joints and high readings at a recent grease test, we can put it right, from multi-storey ducts, access panels and attenuators onwards.
Kitchens in Richmond, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
What ductwork cleaning looks like in Richmond
Food Standards Agency records list about 272 restaurants, cafés and works canteens and about 30 takeaways and sandwich shops in Richmond and the streets around it, up to about 1.5 miles out. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. London jobs usually start after the last service, with loading and roof access agreed with the building first. Fire safety in Richmond falls to London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
A hospital like South Middlesex Hospital, about 1.6 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you look after a school kitchen, at a school such as The Vineyard School or anywhere near Richmond, the holidays are the usual time for a TR19® clean.
Richmond is about 5 miles south-west of Kensington, in Greater London. Whatever kind of site you run in Richmond, ductwork cleaning is something we can help with.

Richmond questions
Which environmental health team covers Richmond?
That is Richmond-Upon-Thames council, whose environmental health officers carry out food hygiene inspections in Richmond. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Does London parking affect a job in Richmond?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, usually makes it simpler.
Are you fully insured?
Yes. Full insurance covers our work and have been trading since 2009.
How is kitchen extract ductwork cleaned?
We get into the duct through its access panels. Heavy grease is scraped out by hand, then the surfaces are degreased with a method that suits the deposit, such as degreasers, hot water or steam.
How much notice should we give?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
Is a quote from pictures possible?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote typically follows within one working day. If pictures are not enough, we will survey first.
What’s the cleaning interval for extract ductwork?
It depends mostly on daily cooking hours. Kitchens cooking 12 to 16 hours a day need it at least every 3 months, while lighter use can go longer.
What paperwork do you give after a duct clean?
You get a photo report with before and after photos, plus a TR19 certificate when the whole system is cleaned. Keep both in the maintenance log.
Common problems we fix in Richmond
A greasy duct is a fire path, in Richmond as anywhere. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
What we are most often called out for:
- Grease pooling at the foot of the riser
- A grease test showing the duct is overdue
- Duct runs with no cleaning record
- Proof of duct cleaning for the insurer
A kitchen near Richmond station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
What your quote should include
- Whether a written report and photos are included
- Whether the work can be done while the site is closed
- Whether the figure could change on the day
- Whether a survey comes first
What affects the quote in Richmond
Some jobs are bigger than they look, and some smaller. The main factors:
- Any permits to work or inductions
- Where the site is and how we reach it
- What state the system is in
- The times the site is available
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
What we need to know
Before you ask for a quote, gather:
- The postcode and the type of business
- When the site is open and when it’s quiet
- Any previous report or certificate
- The roof, plant room or outside wall the system runs to
To help us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Then ring 0345 646 2711, or send details by email.
Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Store the certificate with the fire risk assessment
- Run the extract fan throughout service
- Make sure filters are seated properly
- Have the grease measured if cooking hours go up
Access panels are closed and sealed back up after cleaning, and the area around them is cleaned down. Grease and dirty water are contained and removed.
Run the extract the whole time the kitchen is cooking. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
The process
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from a few hours to several visits, depending on the length of duct. A name and number for whoever controls access to the building in Richmond saves time on the night.
- First the duct route is traced and every access point noted.
- Set points along the runs are tested for grease.
- Through the access panels, thick grease is removed by hand first.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Before we arrive
- Tell us about site rules, permits or sign-in
- Mention any parking or loading restrictions
- Plan for cooking equipment or plant to be off before we arrive
How to get a quote
For a fixed quote, give us a ring on 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
Related advice
What happens if it’s left?
Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean straight away. Putting off the clean only pushes readings higher. Every month a London system goes without attention adds to what has to be done later.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.
