FAQs for Sidcup
Who inspects food businesses in Sidcup?
That is Bexley council, whose environmental health officers carry out food hygiene inspections in Sidcup. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Do you clean school canteen extracts around Sidcup out of term?
Yes, and it’s the easiest time to do it. There are about 29 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Sidcup. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
What’s the cleaning interval for an extract fan?
Daily cooking hours set the minimum, under BESA guidance. Heavy use means at least every 3 months, light use at least every 12, fan included.
Are you fully insured?
Yes. We’re fully insured, and the details are available on request.
How much does extract fan cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, typically ready within one working day.
What if parts of the system cannot be reached?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Extract fan cleaning in Sidcup, done properly
Think of the fan as the system’s heart and the grease as a clot. A greasy fan works harder and moves less air. Our job is to clear it, check it runs smoothly and record what we found so you get a clean bill of health. The work covers fan housings, roof-mounted fans and discharge points, and people most often call us about a smell of hot grease from the extract and a fan that has never been cleaned.
In a London area like Sidcup, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What else we do in Sidcup
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
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.
Fixed quotes for extract fan cleaning in Sidcup
Before we fix a price, we need to know a few things. We check:
- Parking and loading at the site
- Any permits to work or inductions
- Working hours and out-of-hours timing
- The condition of the system
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
What we need to know
When you contact us, it’s useful to have:
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your opening hours and when the area is out of use
- The postcode and the type of business
To help us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Then give us a ring on 0345 646 2711 or use the quote form.
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Keep the fan on whenever the range is lit
- Report grease escaping from the fan
- Don’t store items in front of the fan’s access point
- Make sure the fan is included each time
The photo report shows the fan before and after cleaning. It notes what was done and anything that couldn’t be reached, along with the recommended next clean date.
A change in how the fan sounds is worth noting. Rattles, hums or shaking can be early signs of build-up or wear and early action can save a repair.
What happens if it’s left?
Grease on the fan is grease in the system. TR19® Grease covers the whole extract, fan included, and insurers asking for TR19 cleaning expect the full system. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

Take a look at how cleaning jobs are priced and our accreditations.
Part by part
Impellers and blades
Coated blades move less air. We clean each blade back to its surface, so the fan can run as intended.
Wall fans
The wall around a wall fan can be stained with grease. The outlet is checked as well as the fan.

Sidcup kitchens: local notes
Food Standards Agency records list about 108 restaurants, cafés and works canteens and about 58 takeaways in Sidcup and the streets around it, up to about 1.5 miles out. The fan at the end of each of those extracts collects grease that slows it and wears the motor. In London, kitchens are normally cleaned overnight, when the kitchen is closed and loading is easier. The fire and rescue service for Sidcup is London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
A kitchen near Sidcup station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. If you run catering at a healthcare site, such as a hospital like Queen Mary's Hospital about 1 mile south, the extract may need cleaning more often than a part-time kitchen. Volunteers running a hall kitchen near Holy Trinity Church, or anywhere in Sidcup, may not know when the extract was last cleaned, and a grease test settles it.

How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes a couple of hours per fan, depending on its size and the build-up. A name and number for whoever controls access to the building in Sidcup saves time on the night.
- First we check the fan’s condition and how it sounds.
- Once isolated, we open the fan up.
- Each blade is cleaned so the impeller runs evenly.
- Housing, outlet and the area around the motor are cleaned.
- The fan goes back into service with a report on its condition.
Before we arrive
- Tell us where we can park and unload
- Plan for cooking equipment or plant to be off before we arrive
