Your questions about extract fan cleaning in Nash Mills
Can school kitchens in Nash Mills be cleaned in the holidays?
Yes. The holidays are the usual time for school work. Around Nash Mills, the Food Standards Agency lists about 15 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Do you work at weekends in Nash Mills?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Nash Mills needn’t be disturbed. Just ring 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Why has my extract fan got louder?
Uneven grease on the impeller often causes it. We clean the fan and tell you if anything else, like worn bearings, is to blame.
How long is a fan clean?
Size, access and build-up all affect it. As a guide, it takes an hour or two for one fan, longer when it’s hard to reach.
What about areas you can’t get to?
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.
Does a TR19 kitchen extract clean cover the fan?
Yes, it should be. A TR19 Grease clean covers everything from canopy to discharge, and the fan is a key part of it, so it’s cleaned too.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
Extract fan cleaning in Nash Mills, done properly
If the ducts are the arteries, the fan is the heart. A greasy fan works harder and moves less air. We clean it, run it and note anything that needs a closer look so you get a clean bill of health. If you’re dealing with a smell of hot grease from the extract and vibration from an unbalanced impeller, we can put it right.
In a smaller place like Nash Mills, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
Each visit ends with a written report and pictures, 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 the work involves, part by part
Wall fans
Grease can mark the outside wall around the fan. The outlet is checked as well as the fan.
Inline duct fans
Some fans are built into the duct itself. We get to them through the duct or casing, once they’re isolated.
Staff cleaning versus specialist work
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. That’s our job.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
What we’re called out for in Nash Mills
Grease on a fan is a fire risk, in Nash Mills as anywhere. If grease in the duct catches, the fan and its housing can feed the fire, and a hot, struggling motor does not help.
Look out for these warning signs:
- A fan coated in grease inside its housing
- Less air being pulled from the kitchen
- A motor area thick with grease
- A noisy fan that has got louder over time
A kitchen near Apsley station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Why it’s worth doing now in Nash Mills
The fan is part of the fire path. A TR19 clean that left out the fan wouldn’t cover the whole system, and insurers asking for TR19 cleaning expect the full system. Booking ahead lets us plan the trip to Nash Mills at a time that suits you.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and the price is agreed before any work starts.

Between visits
Results last longer with the right care. We suggest:
- Listen for new noises or vibration from the fan
- Keep the grease filters clean and in place
- Don’t store items in front of the fan’s access point
- File the fan’s report with your other records
File the photo report with your other extract records. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
Make sure the fan is reachable. Clear access means it’s never left out of a clean, whether it’s on a roof, in a ceiling or on a wall.

Keeping each certificate and photo report on file helps show the extract is looked after.
