About our ductwork cleaning in Barwell
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, and our certificates are issued through the BESCA Vent Hygiene Elite portal. If you’re dealing with thick deposits at the bottom of a vertical duct and hardened, baked-on grease in long horizontal runs, we can put it right.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. For a kitchen in Barwell, that normally means a longer system to clean and more access panels to plan around.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What a clean won’t put right
To be straight with you, some problems need a different fix:
- Duct sections that need replacing
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- A duct that’s too small or badly routed for the kitchen (a design issue)
If in doubt, ring 0345 646 2711 or use the quote form and we will say what we think.

For landlords and multi-site operators
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Kitchen extracts in Barwell
Food Standards Agency records include about 10 pubs and bars within 1.5 miles or so of the middle of Barwell. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Barwell is covered by London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Food hygiene inspections in Barwell are the job of Kingston-Upon-Thames council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.
A hall kitchen that only cooks for events, whether near Church of St Mary the Virgin or elsewhere in Barwell, still needs its extract cleaned, just less often. Term dates shape school work: for a school like Ellingham Primary School, an extract clean fits neatly into a half-term or summer break.

Common questions in Barwell
Who would carry out a food hygiene inspection at a kitchen in Barwell?
That’s Kingston-Upon-Thames council, whose environmental health officers carry out food hygiene inspections in Barwell. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Do you clean school canteen extracts around Barwell out of term?
Yes. Half-terms and the summer break are the natural time for school work. With about 12 schools and colleges on the FSA’s register within roughly a mile and a half of Barwell, it pays to plan holiday dates ahead. Send us your term dates when you call us on 0345 646 2711, or send details by email, and we will fit the work in.
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.
What paperwork do you give after a duct clean?
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 much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
How long will the duct clean take?
It takes anything from a few hours to several visits, depending on the length of duct. The survey tells us how long your duct needs.
What should I send you?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.
What’s the cleaning interval for extract ductwork?
The duct is cleaned as part of the whole system, at intervals set by BESA guidance, from every 3 months for heavy use to every 12 months for light use. Grease thickness testing shows whether that’s often enough.
Leave it or put it right?
Dealing with the ductwork in Barwell now beats dealing with it after a problem. The work takes a shift or more, depending on the length of the runs and the number of access points, and we work evenings, overnight and weekends. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.

Different parts, different methods
Access panels
Access panels are the doors that let us into the duct. Where there are none, those sections cannot be cleaned and the report has to say so.
Vertical risers
A riser takes the duct up through one or more floors. Grease collects on the walls and at the foot of the riser, which is one of the points we test.
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes from a few hours to more than one visit, depending on duct length and access. Most London sites can’t stop for the day, so work in Barwell is normally done overnight, early in the morning or at weekends.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Heavy deposits come out by hand, then each section is degreased.
- We close up, re-test, photograph and record anything out of reach.
Before we arrive
- Have your last certificate or report to hand
- Move anything stored near the system
- Allow time for equipment near the work to be turned off and cool down

Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
What we are called out for in Barwell
Damaged or poorly fitted filters let more grease into the duct. The duct then takes grease that the filters should have stopped and it fills faster.
Look out for any of the following:
- Thick crusts of old grease along the duct
- A duct nobody has opened in years
- Heavy grease at the base of a riser
- Duct runs that can’t be reached
If you run a café or takeaway near Chessington South station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
Questions to ask before booking
- Whether a written report and photos are included
- If they look at the system before pricing
- How areas they can’t reach will be recorded
- If the quote is a fixed price or an estimate
