Langley Bottom extract fan cleaning
Our technicians work in Langley Bottom on cleaning of kitchen extract fans, impellers, fan housings and discharge points. Fixed quotes, work around your opening hours and photo reports as standard.
- A fan that hums, whines or rumbles
- A fan left out of previous cleans
- Vibration from an unbalanced impeller
Extract fan cleaning in Langley Bottom, done properly
Grease on a fan isn’t spread evenly. Heavier deposits on some blades throw the impeller off balance, which brings vibration, noise and extra wear on the bearings and motor. Cleaning the impeller and housing puts that right. If you have an extract fan with no cleaning record and a noisy fan that has got louder over time, we can put it right.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What happens on the day
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes an hour or two for most single fans. Somewhere like Langley Bottom, lanes, gates and parking are worth mentioning in advance.
- We locate the fan and plan how to reach and isolate it.
- It’s isolated so it can’t run while we work.
- Grease is scraped off the impeller blades and casing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Make sure equipment near the work can be switched off and left to cool
- Name a contact who can let us in at the agreed time

Related advice
Langley Bottom: your questions answered
Do you work in villages like Langley Bottom?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Can you come to Langley Bottom after we close?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. When you ring 0345 646 2711 or use the quote form, mention when the site is quiet.
How long is a fan clean?
That depends on the fan’s size, its position and how much grease there is. As a guide, it takes an hour or two for one fan, longer when it’s hard to reach.
What’s the cleaning interval for an extract fan?
The fan follows the full system’s interval, from every 3 months for 12 to 16 hours of cooking a day to every 12 months for 2 to 6 hours. Grease readings and the fan’s condition can show it needs more.
Is the fan included in a TR19 clean?
Yes, the fan is cleaned as part of TR19. Anything that can’t be reached is recorded, so you always know what was cleaned.
Do we need to close while you work?
Usually not. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Each site gets its own report and photos.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it does not spread.
Grease, kitchens and Langley Bottom
Food Standards Agency records list about 28 restaurants, cafés and canteens and about 10 takeaways in and around Langley Bottom, up to about a mile and a half out. The fan at the end of each of those extracts collects grease that slows it and wears the motor. It’s North Hertfordshire council that sends environmental health officers to food businesses in Langley Bottom. 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. The fire and rescue service for Langley Bottom is Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Term dates shape school work: for a school like The Thomas Alleyne School, an extract clean fits neatly into a half-term or summer break. Knebworth House, about 1.8 miles south-east, is one of the historic houses near Langley Bottom; if you run event catering at a venue like that, cleans can be booked between functions. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Lister Hospital is the nearest hospital to Langley Bottom, about 2.4 miles north-east.

Managing agents and facilities teams in Langley Bottom
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Staff cleaning versus specialist work
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 will take a look and send you a fixed quote.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Why deal with it now?
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. If the system at a site near Langley Bottom fails, there may be nowhere nearby to move to.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.

Honest limits
Extract fan cleaning cannot fix everything, and we’d rather say so up front. It won’t put right:
- An impeller that is bent or split
- A dirty duct upstream of the fan
- A motor that has burnt out

What the work covers
- In-line fans
- Fan housings
- Discharge points
- Axial fans
- Centrifugal fans
- Roof-mounted fans
Part by part
Fan housings and motors
Motors and their electrics are kept dry and treated with care, and the fan is isolated throughout. Grease around the motor can make it run hotter, so the surrounding area is cleaned carefully.
Kitchens with long cooking hours
Long cooking hours mean more grease reaches the fan. Under BESA guidance, heavy use means cleaning at least every 3 months, fan included.
How we price extract fan cleaning
The diagnosis comes before the price. We look at:
- How many systems or sites are involved
- The condition of the system
- Where the site is and how we reach it
- A single visit or a regular plan
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before work begins.
