How kitchen extract cleaning works in SW4
Duct Doctor has been cleaning kitchen extract systems since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001 and are fully insured. Typical jobs include an extract that has never been cleaned to TR19 and grease drips onto cooking equipment, across discharge points, canopies and hoods and vertical risers.
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes as long as the system needs, from a few hours to several planned visits.
- We start with a survey, so we know every part of the system before we quote.
- Set points are tested for grease thickness and the quote is fixed before we start.
- With the kitchen closed and equipment off and cool, the area is sheeted.
- We clean the canopy, plenum, filters, ducts, risers, fan and discharge.
- Finally the system is re-tested and photographed, and the certificate and report follow.
How we quote
The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.

Kitchen extract cleaning across SW4: local notes
In SW4, a busy kitchen in a place such as Stockwell, Clapham Junction and Battersea and a quiet village kitchen need very different cleaning intervals. Grease readings and BESA’s minimum intervals set the schedule for each.
Much of our work across London and the South East happens in the evening, overnight or at weekends, so sites across SW4 don’t have to lose a day.
Clapham: If you cook for passing trade around Clapham High Street station, the extract can be cleaned between your last and first customer. Term dates shape school work: for a school like Clapham Manor Primary School, an extract clean fits neatly into a half-term or summer break.
Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
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.
What affects the quote in SW4
Sites vary more than people expect. The main factors:
- Travel, parking and unloading
- The size of the system
- Any permits to work or inductions
- Whether it’s a one-off visit or part of a schedule
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- When the site is open and when it’s quiet
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
- Where the site is and what kind of site it is
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.
What we are called out for in SW4
Hours of cooking are the biggest factor. BESA guidance sets minimum cleaning intervals of every 3 months for 12 to 16 hours a day, 6 months for 6 to 12 hours, and 12 months for 2 to 6 hours. They are minimums: measured grease levels set the real interval.
Clients usually contact us after spotting something like this:
- A kitchen taken over without any extract records
- Grease dripping from the canopy or filters
- A kitchen with no current TR19 certificate
- Extraction mentioned at an environmental health visit
What the work involves, part by part
Restaurant and pub kitchens
Losing a service isn’t an option for most restaurants and pubs. Overnight and weekend cleans keep the kitchen trading, and hand back a clean kitchen ready to cook.
Extract fan and discharge
The fan pulls the air through the whole system, and grease that gets past everything else ends up on its blades. We isolate it, open it up and degrease it.
When something else is needed
In fairness, there are a few things this work will not fix:
- Extraction that cannot cope with the cooking because of its design
- Ductwork that’s corroded, split or leaking (that is for a ductwork contractor)
- Blocked drains from a neglected grease trap (a separate service)
Questions from SW4
What do you do with what you remove?
We take it away at the end of the visit. While we work, it’s kept contained to keep the area clean.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and leave the area clean.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
Do you cover SW4?
Yes. Our area takes in London and the counties of South East England, and that includes SW4.
