About our extract fan cleaning in Willian
Is the extract fan louder than it used to be, or the airflow weaker? A few details or a photo help when you call 0345 646 2711 or send us an email, and we’ll give you a fixed quote for extract fan cleaning in Willian, usually within one working day. The work covers roof-mounted fans, axial fans and discharge points, and people most often call us about a motor area thick with grease and fat spreading onto the roof or wall by the fan.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

How the job changes from site to site
Kitchens with long cooking hours
In a busy kitchen, the fan rarely gets a rest, so grease and wear build up together. Cleaning on time helps keep it running.
Fan housings and motors
Inside the casing, grease is thrown onto the walls. We clean it along with the blades.
What extract fan cleaning looks like in Willian
Look up Willian on the FSA’s food hygiene register and you will find about 49 restaurants, cafés and canteens and about 25 takeaways across Willian and its immediate surroundings (about a mile and a half). Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. In Willian, food businesses are inspected by environmental health officers from North Hertfordshire council. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after. Hertfordshire Fire and Rescue Service covers Willian. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
A hospital like Lister Hospital, about 2.5 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run a church or community hall kitchen, near Church of All Saints or elsewhere in Willian, its extract still collects grease from every lunch and event.
Willian is about 1 mile south of Letchworth, in Hertfordshire. We provide extract fan cleaning for commercial premises of every kind in Willian and the rest of Hertfordshire. We cover 381 places across Hertfordshire, from busy centres to quieter spots. For sites nearby, see our Milton Keynes page (24 miles or so).

If your site is just outside Willian, we cover Letchworth (1 mile north), Letchworth Garden City (1 mile north), Great Wymondley (1 mile south-west), Walsworth (2 miles west) and Poets Estate (2 miles south-west).

Willian’s nearest station is Letchworth Garden City station, about 1.4 miles north of the centre.

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Questions from Willian
Which fire and rescue service is responsible for Willian?
Fire safety enforcement in Willian is handled by Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Which council inspects kitchens in Willian?
That is North Hertfordshire council, whose environmental health officers carry out food hygiene inspections in Willian. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
What if parts of the system cannot be reached?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Is TR19 cleaning required by law?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Do you work out of hours?
Yes, and it’s often the best time. We book the visit for when the area is out of use, whether that is late evening, overnight or a weekend.
Do you have insurance?
Yes. We carry full insurance, and we’ve been trading since 2009.
Who has the legal duty for fire safety?
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.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and pictures.

What affects the cost of extract fan cleaning
Your quote is based on your site. We consider:
- Parking and loading at the site
- Whether several sites go on one quote
- Site requirements such as sign-in and permits
- The condition we find in the survey
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before work begins.
What we need to know
To help us quote quickly, please include:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide pictures of the system and the area around it
- Your opening hours and when the area is out of use
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep the grease filters clean and in place
- Keep records of every fan clean
- Run the extract throughout cooking
- Check the report shows the fan was cleaned
Keep the report with the maintenance log and fire risk assessment. It gives a dated record of the fan’s condition, which helps if anything changes later.
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.
Why act early in Willian
Vibration from an unbalanced impeller doesn’t stay small. 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. Equipment tucked in a roof space or outbuilding near Willian rarely gets looked at unless someone books it.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.

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 it goes on the report too. All told, the work takes a couple of hours per fan, depending on its size and the build-up. Somewhere like Willian, lanes, gates and parking are worth mentioning in advance.
- We locate the fan and plan how to reach and isolate it.
- 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.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Plan for cooking equipment or plant to be off before we arrive
- Move anything stored near the system
