Extract fan cleaning for kitchens and businesses in Woollensbrook
Grease on a fan is not spread evenly. Uneven build-up unbalances the impeller, which brings vibration, noise and extra wear on the bearings and motor. A thorough clean removes the cause. Common call-outs are for fat spreading onto the roof or wall by the fan and vibration from an unbalanced impeller, on centrifugal fans, axial fans and fan housings.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
Good records are part of the job. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Leave a clear route to the fan
- File the fan’s report with your other records
- Flag smoke lingering at the canopy
- Report rattles or humming early
When the fan is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.
Run the fan throughout cooking. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
What extract fan cleaning looks like in Woollensbrook
The FSA’s data shows about 12 pubs and bars registered in and around Woollensbrook, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Food hygiene inspections in Woollensbrook are the job of Broxbourne council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked. Hertfordshire Fire and Rescue Service covers Woollensbrook. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Term dates shape school work: for a school like Westfield Community Primary School, an extract clean fits neatly into a half-term or summer break. A hall kitchen that only cooks for events, whether near Church of St Catherine & St Paul or elsewhere in Woollensbrook, still needs its extract cleaned, just less often.

Your questions about extract fan cleaning in Woollensbrook
Can you clean school kitchen extracts in Woollensbrook during the holidays?
Yes, out-of-term visits are normal for schools. There are about 8 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Woollensbrook. Just call 0345 646 2711 or drop us a line with your term dates and we will plan around them.
Which fire authority looks after Woollensbrook?
That’s Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Do you provide a report after cleaning the fan?
Photos, notes on condition and a recommended next date. Keep it with your maintenance log.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
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.
Can you fix a fan that’s worn out?
A fan that needs repair is noted on the report, with what we found. We can repair or replace it, and there’s a 24/7 emergency callout for breakdowns.
Why deal with it now?
A fan that sounds rough in Woollensbrook is often telling you the extract needs a clean. Grease on the fan means grease in the duct before it, so it’s worth checking the whole system. Somewhere as small as Woollensbrook, losing a kitchen or building to a fault is felt by everyone who uses it.
The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.

What we are called out for in Woollensbrook
Grease condenses as the air cools, and a fan out on a roof or wall often sits where the air is coolest. So grease often settles heavily there.
Signs it’s time to call us include:
- Less air being pulled from the kitchen
- A noisy fan that has got louder over time
- Grease around the motor and its mounts
- Burning smells from the fan area
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Woollensbrook is Hertford County Hospital, about 3.1 miles north-west.
Questions to ask before booking
- What happens if part of the system cannot be accessed
- Proof of accreditation you can verify

How the visit works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes a couple of hours per fan, depending on its size and the build-up. If you can send pictures, we can arrive in Woollensbrook knowing what to expect.
- First we check the fan’s condition and how it sounds.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- We clean the casing, the outlet and around the motor.
- The fan goes back into service with a report on its condition.
Getting ready for the visit
