Do you need extract fan cleaning in Blackfen?
Grease on a fan is a fire risk, in Blackfen as anywhere. A fire in the duct can reach the fan and the grease around it and an overworked motor runs hotter.
Signs it’s time to call us include:
- A heavily greased fan housing
- A fan that hums, whines or rumbles
- Hot, greasy smells near the fan
- Grease escaping from the fan outlet
A hospital like Eltham Community Hospital, about 1.7 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Extract fan cleaning for kitchens and businesses in Blackfen
If the extract fan in Blackfen has become noisy, weak or greasy? Tell us about it when you ring 0345 646 2711 or use the quote form, and you will get a fixed price, normally within one working day. The work covers axial fans, discharge points and in-line fans, and common reasons people get in touch are a noisy fan that has got louder over time and an extract fan with no cleaning record.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. For a kitchen in Blackfen, that usually means a longer system to clean and more access panels to plan around.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes a few hours where there are several fans or heavy deposits. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Blackfen.
- Diagnosis first: we look for grease, noise and vibration.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- We clean the casing, the outlet and around the motor.
- The fan goes back into service with a report on its condition.
Before we arrive
- Let us know about parking and loading
- Name a contact who can let us in at the agreed time
- Mention any locked doors, roof access or ceiling voids

Multi-site and managed buildings
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Facilities teams in offices, schools and healthcare sites book us too in Blackfen and across Greater London. Larger estates can be phased building by building around the people who use them.
What affects the quote in Blackfen
A fixed price needs a few facts first. We check:
- Site rules, permits and inductions
- Travel, parking and unloading
- The times the site is available
- What state the system is in
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, ring 0345 646 2711 or email us, and we’ll explain what it covers.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Close-ups of filters, grilles, hatches or access panels
- Wide photos of the system and the area around it
- Any previous report or certificate
- Where the plant sits or the system leaves the building, such as a roof or outside wall
If you need extract fan cleaning in Blackfen, give us a ring on 0345 646 2711 or use the quote form. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. We normally send a fixed quote within one working day.
Staff cleaning versus specialist work
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.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Grease, kitchens and Blackfen
There are about 144 restaurants, cafés and canteens and about 90 takeaways and sandwich shops within 1.5 miles or so of the middle of Blackfen, according to the Food Standards Agency’s register. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected. Blackfen is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
For schools such as Our Lady of the Rosary Catholic Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. Volunteers running a hall kitchen near Church of the Good Shepherd, or anywhere in Blackfen, may not know when the extract was last cleaned, and a grease test settles it.

How the job changes from site to site
Kitchens with long cooking hours
A fan in a long-hours kitchen runs for most of the day, so grease and wear build up together. Regular cleans help it keep going.
Impellers and blades
While the impeller is clean, we can see its condition: chips, distortion or wear. We note any concerns.
Blackfen questions
Does London parking affect a job in Blackfen?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Night visits tend to make loading easier on London streets.
Can you work in Blackfen outside opening hours?
Yes, nights and weekends are routine for us. That way a site in Blackfen does not have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Who is responsible for fire safety on the premises?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. If you are not sure, check your lease and fire risk assessment.
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.
What happens if you can’t reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
What’s the cleaning interval for an extract fan?
At least as often as the rest of the extract, which BESA guidance sets by daily cooking hours: every 3, 6 or 12 months. Some fans need attention sooner.
Do you survey before quoting?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Why is my extract fan noisy?
Uneven grease on the impeller often causes it. We clean the fan and tell you if anything else, like worn bearings, is to blame.

What a clean won’t put right
It’s worth knowing the limits before booking:
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
- Wiring faults to the fan
- An undersized fan that cannot cope
If you’re not sure, just give us a ring on 0345 646 2711 or email us and we will give you a straight answer before booking.
