Ductwork cleaning in St George's Fields
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. Typical jobs include thick deposits at the bottom of a vertical duct and years of grease along the duct floor, on access panels, attenuators and vertical risers.
In London, few kitchens can spare a day to close, so work in St George's Fields 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.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

When to call us in St George's Fields
The further the air travels from the cooking, the cooler it gets. As it cools, the grease it carries condenses onto the duct walls, so duct runs keep collecting grease long after the canopy.
Keep an eye out for these warning signs:
- Years of grease along the duct floor
- Sections of duct with no access panels
- Grease leaking from duct joints
- Duct runs with no cleaning record
A kitchen near Elephant & Castle station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Common questions in St George's Fields
Do you do school kitchen extract cleaning in St George's Fields in the summer holidays?
Yes, and it’s the easiest time to do it. Around St George's Fields, the Food Standards Agency lists about 111 schools and colleges with registered kitchens within a mile and a half or so. You can ring 0345 646 2711 or use the quote form with the dates the site is empty.
Which council inspects kitchens in St George's Fields?
That is Southwark council, whose environmental health officers carry out food hygiene inspections in St George's Fields. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Will the duct clean disrupt the kitchen?
Out of hours, at a time that suits the kitchen. Larger systems may be cleaned over several nights, with the kitchen ready to cook each morning.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then call 0345 646 2711 or email us.
What shows that the ducts need a clean?
We measure it. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
Can you quote from pictures?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Do you work in St George's Fields?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, St George's Fields included.
Is there a survey before the work?
Yes. We always survey first, either from pictures and details you send or on a site visit. A fixed quote follows.
Why it’s worth doing now in St George's Fields
Grease narrows the duct and slows the air. Less air moves, so heat and smoke stay in the kitchen while the fan strains and grease can drip from duct joints. Leaving it on a busy London site only adds to the work.
We do not list prices on the website, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or use the quote form, and we’ll explain what it covers.

What affects the cost of ductwork cleaning
Sites vary more than people expect. The main factors:
- Working hours and out-of-hours timing
- The scale of the work
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
Asking for a quote
To speed up the quote, send us:
- Wide pictures of the system and the area around it
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
To help us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Then ring 0345 646 2711 or use the quote form.
What happens on the day
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a few hours for a short run, longer for long runs and tall risers. We fit London jobs around the building rather than the other way round, so a visit in St George's Fields is typically out of hours.
- First the duct route is traced and every access point noted.
- Set points along the runs are tested for grease.
- We open the panels and scrape out the heaviest grease.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Before we arrive
- Name a contact who can let us in at the agreed time
- Clear the space around the work
- Tell us where we can park and unload
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

What the work involves, part by part
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.
Attenuators and discharge
At the end of the duct is the discharge. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.
What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

What else we do in St George's Fields
St George's Fields kitchens: local notes
The FSA’s data shows about 358 bars, pubs and nightclubs and about 102 hotels and guest houses registered across St George's Fields and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Fire safety in St George's Fields 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. In London, kitchens are normally cleaned overnight, when the kitchen is closed and loading is easier.
A hall kitchen that only cooks for events, whether near Former Church of St Jude or elsewhere in St George's Fields, still needs its extract cleaned, just less often. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; General Lying-In Hospital is the nearest hospital to St George's Fields, about 0.5 miles west.

Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Ask for a grease thickness test if the kitchen gets busier
- Run the extract fan throughout service
- Report any grease dripping from duct joints
- Keep access panels clear of stored items
Every panel we open is refitted when we finish, 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.
