Extract fan cleaning in Potters Bar, done properly
Grease on a fan is not 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. If you have a fan that has never been cleaned and a fan motor running hot under a coat of grease, we can help, from discharge points, axial fans and centrifugal fans onwards.
Around a town like Potters Bar, extract cleaning normally means a restaurant, pub, takeaway or the kitchen of a school or care home. Each has a canopy, filters, ductwork and a fan to keep clear of grease.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Signs you need extract fan cleaning in Potters Bar
A fan collects more grease when the filters let more through. Missing, damaged or badly fitted filters let grease travel the whole system, so the fan takes far more than it should.
If you notice any of these, it’s worth a diagnosis:
- An extract fan that vibrates or rattles
- A fan left out of previous cleans
- Less air being pulled from the kitchen
- Hot, greasy smells near the fan
If you run catering at a healthcare site, such as a hospital like Barnet General Hospital about 3.4 miles south-west, the extract may need cleaning more often than a part-time kitchen.
Questions to ask before booking
- If they look at the system before pricing
- Whether they’re fully insured
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether a written report and photos are included
The process
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. From there, it takes an hour or two for one fan, longer when it’s hard to reach. Three things shape a visit in Potters Bar: when you’re closed, where we can park and how we get to the system.
- We find the fan and check how it’s reached and how it’s isolated.
- With the fan isolated, the housing is opened.
- The impeller and the housing around it are scraped clean.
- We degrease the fan and housing, taking care around the motor.
- We reassemble, run the fan and photograph the result.
Getting ready for the visit
- Clear the space around the work
- Tell us the best time to work, such as after service or at a weekend
- Let us know about parking and loading

Advice
Between visits
A little care between visits keeps the system in better shape. Our advice:
- Keep the fan on whenever the range is lit
- Note any drop in extraction at the canopy
- Keep the grease filters clean and in place
- Don’t store items in front of the fan’s access point
The photo report shows the fan before and after cleaning. It lists what was cleaned and anything we couldn’t reach, along with the recommended next clean date.
Listen to the fan. Rattles, hums or shaking can be early signs of build-up or wear, and catching it early keeps it a cleaning job.
How we price extract fan cleaning
There’s no set price list, because sites vary so much. What we look at:
- The size of the system
- Whether it’s a one-off visit or part of a schedule
- The condition we find in the survey
- Site rules, permits and inductions
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, give us a ring on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.
Helping us quote
Many jobs can be priced from photos and some basics. Useful things to send:
- Problems your staff have spotted
- The times we could work without disrupting the site
- Any access panels or hatches you can see
- How we’d reach plant on a roof or in a plant room
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.
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
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. That part needs specialist access and equipment.
What a clean will not put right
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- A fan that’s too small for the system (a design question)
- A cracked or broken impeller (it needs replacing)
- A motor that has burnt out
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we will say what we think.

Potters Bar kitchens: local notes
Food Standards Agency records include about 10 pubs and bars within about 1.5 miles of central Potters Bar. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. In Potters Bar, food businesses are inspected by environmental health officers from Hertsmere council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. The fire and rescue service for Potters Bar is Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
If you run a church or community hall kitchen, near St. Mary's Church or elsewhere in Potters Bar, its extract still collects grease from every lunch and event. A kitchen near Potters Bar station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Potters Bar questions

Yes. The holidays are the usual time for school work. With about 13 schools and colleges on the FSA’s register within roughly a mile and a half of Potters Bar, it pays to plan holiday dates ahead. Send us your term dates when you phone us on 0345 646 2711, or email photos, and we’ll fit the work in.
Who is the fire and rescue service for Potters Bar?
It’s Hertfordshire Fire and Rescue Service, which covers Potters Bar. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Why is my extract fan noisy?
Often it’s grease on the impeller. Grease collects unevenly and unbalances the impeller, causing vibration and noise. Cleaning may sort it, but worn bearings or a failing motor need a repair.
Will we have to shut during the visit?
Not normally. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so you keep your normal hours.
