Extract fan cleaning in Chiswell Green
Every TR19® Grease clean includes the extract fan, but a fan can also need attention on its own, for example when it’s noisy or vibrating. A fan-only clean is recorded as exactly that. We’re often asked to deal with a fan shaking on its mounts and an extract fan with no cleaning record, on discharge points, axial fans and roof-mounted fans.
Size doesn’t change the work: a kitchen in a place like Chiswell Green gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What the work involves, part by part
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.
Roof-mounted fans
A roof fan sits in cooler air, so grease can settle heavily. We scrape and degrease the blades and casing.
Extract fan cleaning in Chiswell Green: the local picture
According to Food Standards Agency records, there are about 7 pubs and bars within roughly a mile and a half of the centre of Chiswell Green. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in Chiswell Green get their food hygiene inspections from St Albans City council. 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. Fire safety in Chiswell Green falls to Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Healthcare kitchens, like those at hospitals such as Napsbury Hospital (about 2.1 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands. Church and community hall kitchens, near St. Stephen's Church or anywhere around Chiswell Green, are easy to forget, but their extracts collect grease like any other.

Chiswell Green: your questions answered
Do you work in villages like Chiswell Green?
Yes, Chiswell Green is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Which fire and rescue service is responsible for Chiswell Green?
Chiswell Green is in the area of 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.
Do you provide a report after cleaning the fan?
Before and after pictures go into a report, along with notes on the fan’s condition. A full clean adds a TR19 certificate from the BESCA Vent Hygiene Elite portal.
What should I send you?
A short description and a few photos plus the address and your hours. We will ask for anything else we need.
Why has my extract fan got louder?
An unbalanced impeller, normally from uneven grease, is a common cause. We clean the fan and tell you if anything else, like worn bearings, is to blame.
Should the extract fan be cleaned as part of TR19?
Yes, the fan is cleaned as part of TR19. Anything that cannot be reached is recorded, so the record is accurate.
Can you work evenings and weekends?
Yes, and it’s often the best time. We book the visit for when the area is out of use, whether that’s late evening, overnight or a weekend.
Who is the responsible person?
The Fire Safety Order 2005 calls them 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.
Looking after it afterwards
After the visit, a few habits help the work last:
- Do not store items in front of the fan’s access point
- Check the report shows the fan was cleaned
- Notice when the fan starts to sound different
- Keep the grease filters clean and in place
Keep the report with the maintenance log and fire risk assessment. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
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.
Common problems we fix in Chiswell Green
Grease on a fan is a fire risk, in Chiswell Green as anywhere. If grease in the duct catches, the fan and its housing can feed the fire and an overworked motor runs hotter.
What we’re most often called out for:
- A smell of hot grease from the extract
- Thick grease on the impeller and casing
- A fan shaking on its mounts
- Weak extraction at the canopy
Bursars and site managers at schools such as Killigrew Primary and Nursery School tend to book extract cleaning for when the kitchen is empty.
Questions to ask before booking
- Whether a written report and photos are included
- Whether inaccessible sections are listed on the report
- Whether the figure could change on the day
- Whether the quote is based on a survey or pictures
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. Inside the ducts, risers and fan is specialist work, which is where we come in.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
What happens on the day
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes an hour or two for one fan, longer when it’s hard to reach. Everything the job in Chiswell Green needs is worked out beforehand, from the survey.
- The fan is found and its type, access and isolation checked.
- It’s isolated so it can’t run while we work.
- We scrape the heavy grease from the blades and housing.
- Blades, housing and surrounds are degreased with care around the electrics.
- We reassemble, run and photograph the fan.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about permits to work or site inductions
