About our extract fan cleaning in Gosmore
Kitchen extract fans come in different forms: fans on the roof, fans built into the duct run, and fans on an outside wall. Each is isolated and opened in its own way, and we plan that during the survey. Common call-outs are for an extract fan with no cleaning record and grease escaping from the fan outlet, across discharge points, axial fans and in-line fans.
Work in a small place like Gosmore starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the job changes from site to site
Kitchens with long cooking hours
A long-hours kitchen can’t afford a fan failure. A clean fan is less likely to strain, and our 24/7 emergency callout is there if it happens anyway.
Roof-mounted fans
Many kitchen extracts end at a fan on the roof. They’re cleaned where safe access allows, and anything we cannot reach is recorded.
When something else is needed
Extract fan cleaning cannot fix everything, and we will tell you before we start. It does not solve:
- A cracked or broken impeller (it needs replacing)
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
- A failed motor or worn bearings (that needs a fan repair or replacement)
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly.
Where we work
- Fan housings
- Roof-mounted fans
- Centrifugal fans
- Discharge points
- Axial fans
- In-line fans
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Extract fan cleaning around Gosmore
The FSA’s food hygiene register includes about 30 pubs and bars and about 4 hotels and B&Bs within roughly a mile and a half of the centre of Gosmore. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Gosmore is covered by 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. In Gosmore, food businesses are inspected by environmental health officers from North Hertfordshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready.
If you run catering at a historic house or estate in the area (Knebworth House is about 4.7 miles south-east), event kitchens in older buildings often have awkward duct runs that need planning. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Gosmore is Lister Hospital, about 2.6 miles east.

What else we do in Gosmore
Managing agents and facilities teams in Gosmore
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
The process
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes an hour or two for one fan, longer when it’s hard to reach. Pictures of the system and its access let us plan the work in Gosmore before we set off.
- The fan is found and its type, access and isolation checked.
- We isolate the power before opening the housing.
- Grease is scraped off the impeller blades and casing.
- Blades, housing and surrounds are degreased with care around the electrics.
- It’s closed up, run, checked and photographed for the report.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one
- Move anything stored near the system

Signs you need extract fan cleaning in Gosmore
How fast a fan gets greasy in Gosmore depends on the cooking: how many hours a day the kitchen runs and what it cooks. Under BESA guidance, the whole system, fan included, needs cleaning at least every 3, 6 or 12 months depending on daily hours.
Signs it’s time to call us include:
- A fan motor running hot under a coat of grease
- Less air being pulled from the kitchen
- A fan shaking on its mounts
- A fan that hums, whines or rumbles
For schools such as St Ippolyts Church of England Aided Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
Before you book anyone
- How areas they can’t reach will be recorded
- Which accreditations they hold, and whether you can check them
- When the next visit should be, and why
- Whether the work can be done while the site is closed
Leave it or put it right?
An unbalanced fan gets worse, not better. It wears bearings and mounts and can lead to a breakdown and a kitchen can’t cook safely without extraction. A planned clean beats an emergency. If the system at a site near Gosmore fails, there may be nowhere nearby to move to.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
