Greater London · Extract fan cleaning
Welling extract fan cleaning
We cover Welling for extract fan cleaning. Fixed quotes, work around your opening hours and photo reports as standard.
- Grease stains around the discharge
- Vibration from an unbalanced impeller
- Weak extraction at the canopy
The process
A visit follows the same order every time: protect the area, make the system safe, carry out the extract fan cleaning, clear away and leave you the report. The visit itself takes an hour or two for most single fans. Most London sites can’t stop for the day, so work in Welling is typically done overnight, early in the morning or at weekends.
- The fan is found and its type, access and isolation checked.
- We isolate the power before opening the housing.
- We scrape the heavy grease from the blades and housing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
How to prepare
- Dig out any earlier paperwork for the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any sign-in, permit or induction we need
Getting 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. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Extract fan cleaning in Welling
Is the extract fan louder than it used to be, or the airflow weaker? A few details or a photo help when you phone us on 0345 646 2711 or email us, and we’ll give you a fixed quote for extract fan cleaning in Welling, typically within one working day. We are often asked to deal with less air being pulled from the kitchen and a smell of hot grease from the extract, across in-line fans, axial fans and discharge points.
In a London area like Welling, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
Each visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

When to call us in Welling
Fans that are hard to reach are often the ones that get missed. A fan that has never been cleaned can be heavily coated, and the report will show it.
Signs it’s time to call us include:
- Less air being pulled from the kitchen
- A noisy fan that has got louder over time
- Vibration from an unbalanced impeller
- Hot, greasy smells near the fan
If you run a church or community hall kitchen, near St John's Church or elsewhere in Welling, its extract still collects grease from every lunch and event.

Why deal with it now?
A fan that sounds rough in Welling is often telling you the extract needs a clean. If the fan is coated, the duct before it usually is too so a full TR19 clean may be due. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
The cost depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
What you get with us
- Fully insured
- A written report with photos after each visit
- A single point of contact for sites across the South East and London
- Survey first, then a fixed quote

How the job changes from site to site
Inline duct fans
Inline fans can be in tight spaces, so we plan how to reach and clean them. Anything out of reach is recorded.
Wall fans
Grease can mark the outside wall around the fan. The outlet is checked as well as the fan.
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Check filters are seated before cooking
- File the fan’s report with your other records
- Leave a clear route to the fan
- Keep the fan on whenever the range is lit
We take away the grease and dirty water from the fan clean. On a roof or outside wall, we leave the surrounding area tidy.
Don’t run the kitchen with the extract off. Grease settles faster when the air stops moving, so keeping it running helps keep it clean.
Welling kitchens: local notes
Food Standards Agency records include about 43 bars, pubs and nightclubs within about 1.5 miles of central Welling. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Kitchens in Welling get their food hygiene inspections from Bexley council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
If you run a café or takeaway near Welling station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. If you look after a school kitchen, at a school such as Danson Primary School or anywhere near Welling, the holidays are the usual time for a TR19® clean.

Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Your questions about extract fan cleaning in Welling
Who enforces fire safety at workplaces in Welling?
It’s London Fire Brigade, which covers Welling. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can parking be tricky for a job in Welling?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
What makes a kitchen extract fan vibrate?
A common cause is grease. Grease collects unevenly and unbalances the impeller, causing vibration and noise. Cleaning may sort it, but worn bearings or a failing motor need a repair.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
What’s the cleaning interval for an extract fan?
With the whole system, at intervals set by BESA guidance: from 3-monthly for heavy use to 12-monthly for light use. A noisy or heavily coated fan may need it sooner.
How long does extract fan cleaning take?
Size, access and build-up all affect it. As a guide, it takes a couple of hours per fan, depending on its size and the build-up.
What do you do with what you remove?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
Do you work out of hours?
Yes. Evenings, nights and weekends are normal working hours for us, so you do not have to close during trading.
Honest limits
