How we handle extract fan cleaning in St Luke's
Cleaning removes grease, not wear. Anything that looks worn or damaged goes on the report and fan repair or replacement is something we also do. You get an honest view of the fan’s condition. Common call-outs are for a fan motor running hot under a coat of grease and an extract fan that vibrates or rattles, on roof-mounted fans, discharge points and centrifugal fans.
In London, few kitchens can spare a day to close, so work in St Luke's is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

St Luke's: your questions answered
How do you handle parking and loading in St Luke's?
London parking can be tight, so details of loading bays and permits help. Night visits tend to make loading easier on London streets.
Who is the fire and rescue service for St Luke's?
That is London Fire Brigade. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
How long will it take to clean the fan?
That depends on the fan’s size, its position and how much grease there is. Typically it takes a couple of hours per fan, depending on its size and the build-up.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What types of premises do you cover?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Can you clean the fan on its own?
Yes, a fan can be cleaned on its own. It’s useful when a fan is noisy or greasy between full cleans, but it doesn’t replace a full TR19 clean.

Leave it or put it right?
A fan that fails mid-service can stop a kitchen cooking. Grease is often where fan trouble begins, so keeping it clean is part of keeping it running. If it does fail, our 24/7 emergency line is there. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.

What extract fan cleaning looks like in St Luke's
According to Food Standards Agency records, there are about 516 bars, pubs and nightclubs and about 126 hotels and B&Bs in St Luke's and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in St Luke's get their food hygiene inspections from the City of London Corporation. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for St Luke's 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.
Bursars and site managers at schools such as St Luke's CofE Primary School tend to book extract cleaning for when the kitchen is empty. If you cook for passing trade around Old Street station, the extract can be cleaned between your last and first customer.
St Luke's is about 2 miles north of London, in Greater London. Every kind of commercial site in St Luke's, extract fan cleaning is something we can help with. We can work out of hours so the site keeps running. Across Greater London, we cover 764 places, and St Luke's is one of them.
Work in N1, EC1V and EC2A is surveyed, quoted and booked the same way as anywhere else. We cover sites on Long Lane, City Road and Moor Lane and nearby roads. Being close to the A1 and A501, St Luke's is easy for our technicians to reach at any hour. If your site is just outside St Luke's, we cover Finsbury (1 mile south), Barbican Estate (1 mile south), Shoreditch (1 mile east), Hoxton (1 mile north-east) and City of London (1 mile south). Within a short drive, we also cover City of Westminster (3 miles west), Kensington (5 miles west), Walthamstow (5 miles north-east), Hampstead (4 miles north-west), Ruislip (14 miles west) and Brompton (4 miles south-west).
Local landmarks in St Luke's
Around St Luke's, our work takes us to kitchens and buildings near Barts Health Archives, Charterhouse Square School and The Masque Haunt pub and the streets around them. You will also find St Mary-at-Hill (1.1 miles south), Central Foundation Boys' School (less than half a mile east) and Artillery Ground (within half a mile south-east). There’s a railway station in St Luke's itself: Old Street station. A little further out are Gabriel's Wharf (1.3 miles south-west) and Montfichet's Tower (0.9 miles south-west). Not far away are St. James's Park Lake and Barnsbury Wood.
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Book the fan into every full TR19 clean
- Notice when the fan starts to sound different
- Leave a clear route to the fan
- Report grease escaping from the fan
We take away the grease and dirty water from the fan clean. On a roof or outside wall, we leave the surrounding area tidy.
Keep the whole system on its cleaning cycle. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
For landlords and multi-site operators
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Do you need extract fan cleaning in St Luke's?
Each blade collects a slightly different amount. Over time, that imbalance shakes the fan and puts strain on the bearings. Left too long, grease turns into wear.
The symptoms we’re asked about most are:
- Less air being pulled from the kitchen
- Grease stains around the discharge
- A noisy fan that has got louder over time
- A fan left out of previous cleans
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St Luke's Hospital for Lunatics is the nearest hospital to St Luke's, about within half a mile east.
What your quote should include
- Whether inaccessible sections are listed on the report
- Whether the figure could change on the day
- When the next visit should be, and why
- Whether VAT is included
What happens on the day
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes an hour or two for most single fans. A name and number for whoever controls access to the building in St Luke's saves time on the night.
- Diagnosis first: we look for grease, noise and vibration.
- 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.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Mention any parking or loading restrictions
- Find the previous report, if there is one
How to get a quote
The quickest way to a quote is to send photos: 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.
