About our extract fan cleaning in Bernards Heath
If the ducts are the arteries, the fan is the heart. A heart under strain works harder for less. Our job is to clear it, check it runs smoothly and record what we found, before signing it off. The work covers in-line fans, fan housings and roof-mounted fans, and the jobs we see most are grease around the motor and its mounts and an extract fan that vibrates or rattles.
In a smaller place like Bernards Heath, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

How the visit works
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a couple of hours per fan, depending on its size and the build-up. In a place like Bernards Heath, we fit the visit around your hours.
- First we locate the fan and agree how it’s safely isolated.
- The fan is isolated so it can’t start while we work.
- 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.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Dig out any earlier paperwork for the system
- Make sure someone can let us in and lock up afterwards

Advice
Kitchen extracts in Bernards Heath
The FSA’s food hygiene register includes about 60 pubs, bars and clubs and about 4 hotels, B&Bs and guest houses across Bernards Heath and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Bernards Heath sits within the area of 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. It’s St Albans City council that sends environmental health officers to food businesses in Bernards Heath. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Commuter trade near St Albans station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Healthcare kitchens, like those at hospitals such as St Albans City Hospital (about within half a mile west), often cook for long hours, which puts them in BESA’s heavier-use bands.

Different parts, different methods
Inline duct fans
An inline fan can be easy to forget because it’s out of sight. We find it during the survey and include it in the clean.
Impellers and blades
Grease on the leading edges of the blades cuts the fan’s efficiency. We clean each blade back to its surface, so the fan can run as intended.
When it’s something else
Extract fan cleaning cannot fix everything, and we’ll tell you before any work starts. It doesn’t solve:
- A failed motor or worn bearings (that needs a fan repair or replacement)
- An undersized fan that cannot cope
- A cracked or broken impeller (it needs replacing)
If in doubt, ring 0345 646 2711, or email photos and we will say what we think.
Where we work

FAQs for Bernards Heath
Who is the fire and rescue service for Bernards Heath?
Fire safety enforcement in Bernards Heath is handled by Hertfordshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Will you come out to Bernards Heath?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and we will quote them together.
Can you work evenings and weekends?
Yes. Evenings, nights and weekends are normal working hours for us, so the site does not lose a service.
How often should the extract fan be cleaned?
At least as often as the rest of the extract, which BESA guidance sets by daily cooking hours: every 3, 6 or 12 months. A noisy or heavily coated fan may need it sooner.
What if the fan needs more than a clean?
Anything beyond cleaning is flagged, with what we found. We can repair or replace it, and there’s a 24/7 emergency callout for breakdowns.
Do you offer extract fan cleaning separately?
Yes, we can clean just the fan. It’s useful when a fan is noisy or greasy between full cleans, but it does not replace a full TR19 clean.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
Common problems we fix in Bernards Heath
A greasy fan in Bernards Heath is fuel at the end of the duct. If grease in the duct catches, the fan and its housing can feed the fire and an overworked motor runs hotter.
Most sites get in touch after spotting something like this:
- A heavily greased fan housing
- An extract fan with no cleaning record
- A smell of hot grease from the extract
- A noisy fan that has got louder over time
Bursars and site managers at schools such as Garden Fields Junior Mixed and Infant School tend to book extract cleaning for when the kitchen is empty.

What happens if it’s left?
Grease on a roof fan can also escape outside. It marks the area around the outlet and leaves more fuel outside, which is one more reason to keep it clean. It’s better to plan the work at a site near Bernards Heath than wait for a failure.
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.

Looking after it afterwards
Results last longer with the right care. We suggest:
- Keep each photo report with the maintenance log
- Flag smoke lingering at the canopy
- Never cook with a filter missing
- Run the extract throughout cooking
Once it’s clean, the fan is closed up and run to check it’s working smoothly. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.
A change in how the fan sounds is worth noting. New noise or vibration often means grease is building on the impeller and early action can save a repair.
What your team can do, and what needs us
Staff cleaning and specialist work are not 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.
