What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Extract fan cleaning for kitchens and businesses in Chipperfield
Any fan serving a kitchen in Chipperfield is cleaned the same careful way as anywhere else: isolated first, then opened, scraped and degreased. Your report shows the impeller as we found it and as we left it. The work covers discharge points, fan housings and centrifugal fans, and common reasons people get in touch are grease escaping from the fan outlet and grease around the motor and its mounts.
In a small place like Chipperfield, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What affects the cost of extract fan cleaning
A fixed price needs a few facts first. We look at:
- The number of sites or systems
- The scale of the work
- Where the site is and how we reach it
- The condition of the system
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- The paperwork from the last visit, if you have it
- When the site is open and when it’s quiet
- Wide photos of the system and the area around it
- Problems your staff have spotted
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

Kitchen extracts in Chipperfield
Food Standards Agency data counts about 8 cafés, restaurants and staff canteens in Chipperfield and the streets around it, up to about 1.5 miles out. The fan at the end of each of those extracts collects grease that slows it and wears the motor. Fire safety in Chipperfield falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Environmental health officers from Dacorum council inspect food businesses in Chipperfield. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
School kitchens, at schools like Kings Langley School for example, are typically cleaned in the holidays so no lunches are lost. If you run catering at a historic house or estate in the area (Chenies Manor House is about 2.9 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning.

Do you need extract fan cleaning in Chipperfield?
A greasy fan in Chipperfield is fuel at the end of the duct. A fire in the duct can reach the fan and the grease around it and an overworked motor runs hotter.
Common reasons sites call us are:
- A fan shaking on its mounts
- A fan left out of previous cleans
- Hot, greasy smells near the fan
- Grease around the motor and its mounts
A hall kitchen that only cooks for events, whether near Church of St Paul or elsewhere in Chipperfield, still needs its extract cleaned, just less often.
What your quote should include
- Proof of accreditation you can verify
- If the quote is a fixed price or an estimate
- What paperwork you get at the end
- How areas they cannot reach will be recorded
What the work involves, part by part
Roof-mounted fans
On a roof, the air is cooler and grease drops out faster. We scrape and degrease the blades and casing.
Inline duct fans
Space around an inline fan can be tight, so the method is planned in advance. If it cannot be reached fully, the report says so.
What we do, step by step
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes a couple of hours per fan, depending on its size and the build-up. Pictures of the system and its access let us plan the work in Chipperfield before we set off.
- First we check the fan’s condition and how it sounds.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- We clean the casing, the outlet and around the motor.
- We run the fan and note its condition in the photo report.
Getting ready for the visit
- Agree a time when the area can be out of use
- Mention any parking or loading restrictions
- Clear loose items from the work area
Getting a quote
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.

FAQs for Chipperfield
Will you come out to Chipperfield?
Yes, Chipperfield is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can you work in Chipperfield outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Chipperfield does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Do you need to turn the fan off to clean it?
We always isolate the fan first, so it can’t run during the clean. That means the extract is off, so we clean while the kitchen is closed.
Where does the waste go?
We take it away at the end of the visit. During the work, it’s contained to keep the area clean.
What if parts of the system can’t be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
What’s the cleaning interval for an extract fan?
With the whole system, at intervals set by BESA guidance: every 3, 6 or 12 months. Some fans need attention sooner.
How much notice do you need?
Earlier is better, especially for out-of-hours work. We typically quote within one working day, and there’s a 24/7 line for emergencies.
Who is responsible for fire safety on the premises?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
