Fixed quotes for extract fan cleaning in Nash
Sites vary more than people expect. The main factors:
- Access, including roofs, risers and ceiling voids
- The number of sites or systems
- What state the system is in
- How big the system is
No two sites are the same, 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.
What to send for a quote
There’s no need for technical detail. Just send:
- When the site is open and when it’s quiet
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
- The paperwork from the last visit, if you have it
The quickest way to a quote is to send photos: 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.
About our extract fan cleaning in Nash
Every kitchen extract depends on its fan: it draws the air through the canopy and ductwork and pushes it outside. Grease that gets past everything else ends up on its blades and housing and we clean it off. If you are dealing with a noisy fan that has got louder over time and burning smells from the fan area, we can put it right.
London kitchens tend to trade late and open early, so extract cleaning in Nash is typically done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What else we do in Nash
Managing agents and facilities teams in Nash
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
The process
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes a couple of hours per fan, depending on its size and the build-up. Most London sites can’t stop for the day, so work in Nash is usually done overnight, early in the morning or at weekends.
- First we locate the fan and agree how it’s safely isolated.
- With the fan isolated, the housing is opened.
- Grease is scraped from the impeller blades and the inside of the housing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- We reassemble, run the fan and photograph the result.
How to prepare
- Clear the space around the work
- Tell us about site rules, permits or sign-in
- Find the previous report, if there is one

Related advice
Do you need extract fan cleaning in Nash?
The cooler the air, the more grease drops out, and on a roof or outside wall the fan can be in some of the coolest air in the system. So grease often settles heavily there.
Common reasons sites call us include:
- Rough running from the extract fan
- A smell of hot grease from the extract
- A fan left out of previous cleans
- A fan that no longer moves enough air
Where a hall near Keston Parish Church, or anywhere in Nash, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What extract fan cleaning looks like in Nash
Look up Nash on the FSA’s food hygiene register and you’ll find about 12 cafés, restaurants and staff canteens and about 13 sandwich bars and takeaways in and around Nash, up to about a mile and a half out. Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. In London, kitchens are normally cleaned overnight, when the kitchen is closed and loading is easier. Environmental health officers from Bromley council inspect food businesses in Nash. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
Term dates shape school work: for a school like Wickham Common Primary School, an extract clean fits neatly into a half-term or summer break. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Down House is about 2.4 miles south-east), access may need planning.

Green spaces nearby include Hutchinson's Bank and Summer Hill.
Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Keeping the system healthy
After the visit, a few habits help the work last:
- Keep access to the fan clear
- Book the fan into every full TR19 clean
- Don’t turn the fan off mid-service
- Listen for new noises or vibration from the fan
When we’ve finished, the fan is reassembled and run. If anything seems wrong, from vibration to wear, we note it, so you can plan any repair.
Stick to the interval for the full extract. Regular full cleans keep the fan from building up heavy deposits, in line with BESA guidance.
What happens if it’s left?
Grease on the fan is grease in the system. A TR19 clean that left out the fan wouldn’t cover the whole system, and insurers asking for TR19 cleaning expect the full system. For a site in Nash, fitting the work in overnight now is far easier than closing at short notice later.
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

Questions from Nash
Who would carry out a food hygiene inspection at a kitchen in Nash?
In Nash, it’s Bromley council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Do you work overnight in Nash?
Yes, evening, overnight and weekend work is normal for us. That way a site in Nash does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Is there a survey before the work?
Yes. We always survey first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
Does the law say we must follow TR19?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.
Are you fully insured?
Yes. We are fully insured, and we can share the details when you need them.
What do you do with what you remove?
It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
How often should the extract fan be cleaned?
Daily cooking hours set the minimum in BESA guidance. Heavy use means at least every 3 months, light use at least every 12, fan included.
