Extract fan cleaning for kitchens and businesses in Hadley
We’ve been trading since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we are fully insured, with CHAS, SafeContractor and ISO 9001. If you are dealing with grease around the motor and its mounts and an extract fan that vibrates or rattles, we can help.
In a London area like Hadley, 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.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What happens on the day
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a few hours where there are several fans or heavy deposits. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Hadley.
- We find the fan and check how it’s reached and how it’s isolated.
- Power to the fan is isolated before anyone touches it.
- Grease is scraped from the impeller blades and the inside of the housing.
- Blades, housing and the area around the motor are degreased with care.
- The fan is put back into service, checked and photographed.
How to prepare
- Let us know about parking and loading
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us the best time to work, such as after service or at a weekend
How to get a quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price, before work begins.

Aftercare tips
So the system stays in good health:
- Note any drop in extraction at the canopy
- Don’t turn the fan off mid-service
- Keep access to the fan clear
- Keep records of every fan clean
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. If only the fan is cleaned, the photo report says so.
Stick to the interval for the full extract. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
Grease, kitchens and Hadley
Look up Hadley on the FSA’s food hygiene register and you’ll find about 53 restaurants, cafés and canteens and about 25 sandwich bars and takeaways across Hadley and its immediate surroundings (about a mile and a half). Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. Kitchens in Hadley get their food hygiene inspections from Barnet council. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Hadley falls to 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.
If you run catering at a healthcare site, such as a hospital like Barnet General Hospital about 0.7 miles south-west, the extract may need cleaning more often than a part-time kitchen. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Wyllyotts Manor is about 2.8 miles north), access may need planning.

FAQs for Hadley
Who carries out food hygiene inspections in Hadley?
In Hadley, it’s Barnet council that carries out food hygiene inspections. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Do you do school kitchen extract cleaning in Hadley in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 21 schools and colleges on the FSA’s register within roughly a mile and a half of Hadley, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and pictures.
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: from 3-monthly for heavy use to 12-monthly for light use. Some fans need attention sooner.
Do you have insurance?
Yes. Full insurance covers our work, and we have been trading since 2009.
How much notice should we give?
Earlier is better, especially for out-of-hours work. We typically quote within one working day, and there’s a 24/7 line for emergencies.
How long is a fan clean?
Allow an hour or two for most single fans. We’ll confirm the time when we quote.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Different parts, different methods
Fan housings and motors
Motors and their electrics are kept dry and treated with care, and the fan is isolated throughout. Grease on and around the motor can trap heat, so the surrounding area is cleaned carefully.
Roof-mounted fans
Many kitchen extracts end at a fan on the roof. They’re cleaned where safe access allows, with any limits noted.
Why deal with it now?
Vibration from an unbalanced impeller does not stay small. It wears bearings and mounts and can lead to a breakdown and a kitchen cannot cook safely without extraction. Cleaning it early is far less disruptive. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before work begins.

- In-line fans
- Discharge points
What we’re called out for in Hadley
Grease on a fan is a fire risk, in Hadley as anywhere. If grease in the duct catches, the fan and its housing can feed the fire and an overworked motor runs hotter.
Any of these means the system needs a check-up:
- Less air being pulled from the kitchen
- A fan that hums, whines or rumbles
- A fan shaking on its mounts
- Burning smells from the fan area
Bursars and site managers at schools such as Susi Earnshaw Theatre School tend to book extract cleaning for when the kitchen is empty.
Questions to ask before you book
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether VAT is included
- Whether the price is fixed
- How they set the interval to the next visit
Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
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.
