Extract fan cleaning in Colney Butts, Hertfordshire

Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
How we handle extract fan cleaning in Colney Butts
Think of the fan as the system’s heart and the grease as a clot. A heart under strain works harder for less. Our job is to clear it, check it runs smoothly and record what we found, before signing it off. The work covers axial fans, roof-mounted fans and fan housings, and the jobs we see most are a motor area thick with grease and grease stains around the discharge.
In a smaller place like Colney Butts, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Extract fan cleaning in Colney Butts: the local picture
Food Standards Agency records list about 213 restaurants, cafés and works canteens and about 66 takeaways within about 1.5 miles of central Colney Butts. Any of those kitchens with a canopy relies on a fan that gathers grease as it runs. Food hygiene inspections in Colney Butts are the job of Watford council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Hertfordshire Fire and Rescue Service covers Colney Butts. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Healthcare kitchens, like those at hospitals such as Watford General Hospital (about less than half a mile south-west), often cook for long hours, which puts them in BESA’s heavier-use bands. Commuter trade near Watford High Street station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

How we price extract fan cleaning
The quote reflects the site in front of us. We take into account:
- Site rules, permits and inductions
- One-off work versus a regular cycle
- When the work can happen, such as evenings, overnight or weekends
- Where the site is and how we reach it
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.
What to send for a quote
To help us quote quickly, send us:
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
- The site address and the type of premises
- Any previous report or certificate
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
Questions from Colney Butts
Can a school canteen extract in Colney Butts be done out of term time?
Yes, out-of-term visits are normal for schools. With about 35 schools and colleges on the FSA’s register within roughly a mile and a half of Colney Butts, it pays to plan holiday dates ahead. You can call us on 0345 646 2711 or send us an email with the dates the site is empty.
Which fire and rescue service is responsible for Colney Butts?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Colney Butts. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Do you offer extract fan cleaning separately?
Yes, we can clean just the fan. That helps when the fan needs attention before the next full clean, but it doesn’t replace a full TR19 clean.
Do you survey before quoting?
Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Do you repair extract fans as well as clean them?
A clean won’t mend wear. We repair and replace extract fans as well, with a fixed quote first.
Do you need to turn the fan off to clean it?
It has to be off and isolated before anyone touches it. Cleans are done when the kitchen is closed, so cooking isn’t affected.
What happens if it’s left?
Vibration from an unbalanced impeller doesn’t stay small. It wears bearings and mounts and can lead to a breakdown, which may leave the kitchen without extraction. A planned clean beats an emergency. Systems on quieter sites still build up dirt and wear, just more slowly.
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.
Why us?
- One number for every site across the South East and London
- Evenings, overnight and weekends, plus 24/7 emergency callout
- BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Fixed quotes from a survey or photos

Landlords, agents and facilities managers
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
When to call us in Colney Butts
Grease builds up unevenly on the blades. The difference throws the impeller off balance, wearing bearings and mounts. Left too long, grease turns into wear.
It’s time to book a visit if you see:
- Grease around the motor and its mounts
- A fan left out of previous cleans
- A fan coated in grease inside its housing
- An extract fan that vibrates or rattles
If you look after a school kitchen, at a school such as Watford Grammar School for Girls or anywhere near Colney Butts, the holidays are the usual time for a TR19® clean.
What your quote should include
- What’s included in the scope, part by part

Different parts, different methods
Kitchens with long cooking hours
In a busy kitchen, the fan rarely gets a rest, which means grease and wear add up quickly. Regular cleans help it keep going.
Roof-mounted fans
Roof fans also discharge grease onto the roof around them, so the outlet area is checked too. Heavy staining is noted on the report.
