Extract fan cleaning in Northaw
Not all extract fans are the same: roof-mounted units, inline fans within the duct, and wall fans. The way in depends on the type and the survey shows us how to reach it. The work covers discharge points, axial fans and in-line fans, and the jobs we see most are a noisy fan that has got louder over time and a fan that no longer moves enough air.
For a kitchen in or near Northaw, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Kitchen extracts in Northaw
There are about 14 restaurants, cafés and works canteens and about 5 sandwich bars and takeaways in and around Northaw, up to about a mile and a half out, according to the Food Standards Agency’s register. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. The fire and rescue service for Northaw is Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. It’s Welwyn Hatfield council that sends environmental health officers to food businesses in Northaw. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand.
Church and community hall kitchens, near Parish Church of St Thomas A Becket or anywhere around Northaw, are easy to forget, but their extracts collect grease like any other. Historic houses near Northaw, such as Wyllyotts Manor about 2.1 miles west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Signs you need extract fan cleaning in Northaw
Grease builds up unevenly on the blades. Over time, that imbalance shakes the fan and puts strain on the bearings. Left too long, grease turns into wear.
Clients typically contact us when they notice one of these:
- A fan coated in grease inside its housing
- Weak extraction at the canopy
- Vibration from an unbalanced impeller
- A fan motor running hot under a coat of grease
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Chase Farm Hospital is the nearest hospital to Northaw, about 3.3 miles south-east.
Questions to ask before you book
- When the next visit should be, and why
- If they look at the system before pricing
- Whether the work can be done while the site is closed
- Whether the figure could change on the day
Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
Facilities teams in offices, schools and healthcare sites book us too in Northaw and across Hertfordshire. Larger estates can be phased building by building to keep disruption down.
How it works
Every visit runs to the same pattern: protect the area, make the system safe, carry out the extract fan cleaning, tidy up and leave you the report. The visit itself takes a couple of hours per fan, depending on its size and the build-up. In a small place like Northaw, the journey is planned ahead and the visit arranged around the site’s hours.
- Diagnosis first: we look for grease, noise and vibration.
- Once isolated, we open the fan up.
- Each blade is cleaned so the impeller runs evenly.
- We clean the casing, the outlet and around the motor.
- The fan goes back into service with a report on its condition.
Preparing for the visit
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool
- Tell us where we can park and unload

Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.

Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep the fan on whenever the range is lit
- Do not store items in front of the fan’s access point
- Check the report shows the fan was cleaned
- File the fan’s report with your other records
Once it’s clean, the fan is closed up and run to check it’s working smoothly. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.
A change in how the fan sounds is worth noting. New noise or vibration often means grease is building on the impeller, and catching it early keeps it a cleaning job.
Your questions about extract fan cleaning in Northaw
Can you get to a site in Northaw?
Yes. Villages and rural sites across the South East are part of our work, Northaw included. Photos of the system and directions to the site help us plan the visit.
Do you work at weekends in Northaw?
Yes, nights and weekends are routine for us. The work in Northaw can fit around your hours. Just call us on 0345 646 2711 or send us an email with your opening times and we will plan around them.
Do you offer extract fan cleaning separately?
Yes, if the fan needs it. We will often suggest checking the duct too, as a greasy fan normally means a greasy duct, but the choice is yours.
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.
Who has the legal duty for fire safety?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
Is the fan included in a TR19 clean?
Yes, the fan is part of a full TR19® Grease clean. We clean it alongside the canopy, ductwork and discharge.
Will we have to shut during the visit?
Not normally. The area we’re working in has to be out of use while we are there, so we book a time when it would be closed anyway.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Part by part
Roof-mounted fans
Roof fans sit at the top of the riser. We clean them where they can be safely reached, and anything we cannot reach is recorded.
Inline duct fans
An inline fan can be easy to forget because it’s out of sight. We find it during the survey and include it in the clean.

- Whether we need access equipment or extra panels
- What state the system is in
