- Grease around the motor and its mounts
- Grease escaping from the fan outlet
- A heavily greased fan housing
How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes a couple of hours per fan, depending on its size and the build-up. For a village or hamlet like Mackerye End, tell us about narrow lanes, gates and parking when you book.
- First we locate the fan and agree how it’s safely isolated.
- Power to the fan is isolated before anyone touches it.
- The impeller and the housing around it are scraped clean.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- We reassemble, run the fan and photograph the result.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
To help us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711 or email us.
Advice
How we handle extract fan cleaning in Mackerye End
Every kitchen extract depends on its fan: it pulls air from the canopy, through the duct and out of the building. Whatever grease slips past the filters and duct reaches the fan and we clean it off. Common call-outs are for weak extraction at the canopy and vibration from an unbalanced impeller, on centrifugal fans, roof-mounted fans and discharge points.
Somewhere as small as Mackerye End, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Do you need extract fan cleaning in Mackerye End?
Fans that are hard to reach are often the ones that get missed. A fan that has never been cleaned can be heavily coated, and the report will show it.
Common reasons sites call us are:
- A fan shaking on its mounts
- Grease stains around the discharge
- Burning smells from the fan area
- Less air being pulled from the kitchen
Term dates shape school work: for a school like Sauncey Wood Primary School, an extract clean fits neatly into a half-term or summer break.

Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Listen for new noises or vibration from the fan
- Look for grease stains near the discharge
- Run the extract throughout cooking
- Flag smoke lingering at the canopy
We take away the grease and dirty water from the fan clean. On a roof or outside wall, we leave the surrounding area tidy.
The fan stays cleaner when less grease gets past the canopy. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.
How we price extract fan cleaning
You will get a fixed price before any work starts. It takes into account:
- The scale of the work
- Parking and loading at the site
- One-off work versus a regular cycle
- Any permits to work or inductions
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711 or send us an email for straight advice and a fixed quote.
What we need to know
Photos let us diagnose from a distance. Try to include:
- Photos showing the whole system and its surroundings
- Any previous report or certificate
- The site address and the type of premises
- Detail shots of panels, filters and grilles

What extract fan cleaning can’t fix

Not sure which it is? You can ring 0345 646 2711, or send details by email and we’ll tell you honestly.

Why deal with it now?
Vibration from an unbalanced impeller does not stay small. It can wear the bearings and lead to failure, which may leave the kitchen without extraction. A planned clean beats an emergency. A planned visit to Mackerye End is easier to arrange than an emergency callout.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.

Extract fan cleaning around Mackerye End
Food Standards Agency records list about 3 cafés, restaurants and staff canteens across Mackerye End and its immediate surroundings (about a mile and a half). Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. Mackerye End sits within the area of Hertfordshire Fire and Rescue Service. 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. In Mackerye End, food businesses are inspected by environmental health officers from St Albans City council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

Common questions in Mackerye End
Can school kitchens in Mackerye End be cleaned in the holidays?
Yes, holiday work suits schools best. There are about 5 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Mackerye End. You can call 0345 646 2711 or use the quote form with the dates the site is empty.
Will you come out to Mackerye End?
Yes, Mackerye End is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
Who is the responsible person?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
What makes a kitchen extract fan vibrate?
A common cause is grease. 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.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
Is TR19 cleaning required by law?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Do we need to close while you work?
Usually not. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages so parts stay in use.
