Extract fan cleaning in Manor House
Grease on a fan isn’t spread evenly. Heavier deposits on some blades throw the impeller off balance, which brings vibration, noise and extra wear on the bearings and motor. A thorough clean removes the cause. Typical jobs include grease stains around the discharge and a heavily greased fan housing, on roof-mounted fans, in-line fans and centrifugal fans.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. In Manor House, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
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.

Common problems we fix in Manor House
By the time air reaches the fan, it has passed the canopy, filters and duct. The grease that’s left lands on the blades and the casing, and the spinning blades fling it onto the walls of the housing.
Common reasons sites call us include:
- A fan coated in grease inside its housing
- A fan that hums, whines or rumbles
- Grease around the motor and its mounts
- Less air being pulled from the kitchen
If you run a café or takeaway near Harringay Green Lanes station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
What to look for in a quote
- Proof of accreditation you can verify
- What insurance they carry
- When they can work, and whether that is outside your opening hours
- Whether the price is fixed
How it works
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes a couple of hours per fan, depending on its size and the build-up. Getting kit into a London building takes planning, so let us know where we can load and park in Manor House.
- We locate the fan and plan how to reach and isolate it.
- We isolate the power before opening the housing.
- We scrape the heavy grease from the blades and housing.
- Blades, housing and surrounds are degreased with care around the electrics.
- It’s closed up, run, checked and photographed for the report.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Make sure someone can let us in and lock up afterwards
- Mention any sign-in, permit or induction we need
Getting a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Related advice
Leave it or put it right?
Grease on the fan is grease in the system. A TR19 clean that left out the fan wouldn’t cover the whole system and many insurers require the full system to be cleaned to TR19. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, call 0345 646 2711 or drop us a line for straight advice and a fixed quote.

Keeping the system healthy
Once we’ve finished, these simple steps help:
- Make sure the fan is included each time
- Don’t turn the fan off mid-service
- File the fan’s report with your other records
- Notice when the fan starts to sound different
Where the fan needs repair rather than cleaning, the report says so. We also repair and replace extract fans, so you have one point of contact.
Listen to the fan. New noise or vibration often means grease is building on the impeller, and catching it early keeps it a cleaning job.
What affects the cost of extract fan cleaning
The survey tells us what the work involves. We look at:
- When the work can happen, such as evenings, overnight or weekends
- The condition of the system
- How big the system is
- Site rules, permits and inductions
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Detail shots of panels, filters and grilles
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Manor House: your questions answered
Do you work at weekends in Manor House?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
Which council inspects kitchens in Manor House?
That is Hackney council, whose environmental health officers carry out food hygiene inspections in Manor House. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
How do you protect the area?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.
Do we need to close while you work?
Not typically. We need the work area to ourselves while we’re on site, so we book a time when it would be closed anyway.
Where does the waste go?
We take it away when we go. While we work, it’s kept contained to keep the area clean.
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 drop us a line.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
How long is a fan clean?
That depends on the fan’s size, its position and how much grease there is. As a guide, it takes a few hours where there are several fans or heavy deposits.
Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building to keep disruption down.
Honest limits
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- A fan that is too small for the system (a design question)
- A failed motor or worn bearings (that needs a fan repair or replacement)
- A faulty speed controller or isolator
Not sure which it is? You can call us on 0345 646 2711, or send details by email and we will tell you honestly.
Parts of the system we cover
- Discharge points
- In-line fans
- Fan housings
- Centrifugal fans
- Roof-mounted fans
- Axial fans
Grease, kitchens and Manor House
Look up Manor House on the FSA’s food hygiene register and you will find about 579 cafés, restaurants and staff canteens and about 161 sandwich bars and takeaways within 1.5 miles or so of the middle of Manor House. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. In London, kitchens are normally cleaned overnight, when the kitchen is closed and loading is easier. Kitchens in Manor House get their food hygiene inspections from Hackney council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
A hall kitchen that only cooks for events, whether near Church of St Olave or elsewhere in Manor House, 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; City of London Maternity Hospital is the nearest hospital to Manor House, about 1 mile west.
