Ductwork cleaning in St Margarets
The ductwork is where an extract clean is won or lost. Sections with no way in can go uncleaned for years. Each section we can reach is cleaned, and any we can’t is written down, so you know exactly where you stand. Common call-outs are for grease seeping out of the duct seams and high readings at a recent grease test, on horizontal duct runs, bends and junctions and vertical risers.
London kitchens tend to trade late and open early, so work in St Margarets 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.
The sign-off is always in writing: a written report, dated and illustrated with photos, 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.

How the visit works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a shift or more, depending on the length of the runs and the number of access points. Loading bays, visitor permits and roof access are the first things we ask about for a site in St Margarets.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Find the previous report, if there is one
- Move anything stored near the system

Related advice
In-house cleaning or a specialist?
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
What we’re called out for in St Margarets
The further the air travels from the cooking, the cooler it gets. Cooling air drops its grease onto the inside of the duct, which is why ducts go on gathering grease well beyond the filters.
What we’re most often called out for:
- Duct runs that cannot be reached
- Duct runs with no cleaning record
- Proof of duct cleaning for the insurer
- Grease seeping out of the duct seams
Bursars and site managers at schools such as Worple Primary School tend to book extract cleaning for when the kitchen is empty.
What your quote should include
- If the quote is a fixed price or an estimate
- What paperwork you get at the end
- Whether a survey comes first
- What insurance they carry

Why act early in St Margarets
Fire inside a duct is out of sight and out of reach. It can travel through the ductwork to other parts of the building, which is why the duct matters as much as the canopy. In St Margarets, a planned overnight visit is much easier than closing unexpectedly.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

Common questions in St Margarets
Which fire authority looks after St Margarets?
London Fire Brigade is the fire and rescue service for St Margarets. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Who would carry out a food hygiene inspection at a kitchen in St Margarets?
That is Richmond-Upon-Thames council, whose environmental health officers carry out food hygiene inspections in St Margarets. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can you quote from photos?
Typically, yes. 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 photos aren’t enough, we’ll survey first.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Will the duct clean disrupt the kitchen?
We plan the clean when you are not cooking. Most kitchens book overnight or weekend cleans, so no service is lost.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
What about areas you can’t get to?
We record them on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
What the work involves, part by part
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, and we clean them section by section through access panels.
Bends and transitions
Grease tends to pile up at elbows. We clean it back by hand and with degreaser, and readings are taken there before and after.
Ductwork cleaning in St Margarets: the local picture
The FSA’s food hygiene register includes about 55 pubs, bars and clubs and about 10 hotels and guest houses across St Margarets and its immediate surroundings (about a mile and a half). A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier. It’s Richmond-Upon-Thames council that sends environmental health officers to food businesses in St Margarets. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Historic houses near St Margarets, such as Richmond House about 1 mile south, are a reminder that older buildings with event kitchens can have long, awkward duct routes. A kitchen near St Margarets (London) station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
