Hertfordshire · Extract fan repair and replacement
Letchmore Heath extract fan repair
Extract fan repair in Letchmore Heath from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- A fan running too slowly to clear the kitchen
- A fan worn beyond sensible repair
- A humming noise from the fan motor
Why deal with it now?
In kitchens with an interlocked gas supply, no extract can mean no cooking. Even without an interlock, cooking without extraction is not sensible, so a failing fan is worth dealing with early. Planning a trip to Letchmore Heath ahead is easier for everyone than a rushed one.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before any work starts.

Extract fan repair in Letchmore Heath
Every fan job begins with finding the fault. Noise can come from grease on the impeller, worn bearings or a slipping belt, while a fan that won’t start may have a motor or control fault. You hear what we have found before any work goes ahead. We are often asked to deal with a dead fan motor and a humming noise from the fan motor, across roof and wall fans, belts and pulleys and kitchen extract fans.
For a fan repair in or near Letchmore Heath, the more you tell us about the fan, the better the first visit: a photo of the fan, the details on its label and the access arrangements help us plan.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What else we do in Letchmore Heath
When a fan fails in Letchmore Heath
Food Standards Agency records list about 18 restaurants, cafés and works canteens and about 7 takeaways in and around Letchmore Heath, up to about a mile and a half out. Wherever they cook under a canopy, a failed extract fan stops the kitchen. Kitchens in Letchmore Heath get their food hygiene inspections from Hertsmere council. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. That makes a fan repair urgent rather than something to put off. We cover Letchmore Heath, about 16 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
For school kitchens, at schools like Fair Field Junior School for example, a planned fan repair in the holidays avoids losing lunches in term time.

When to call us in Letchmore Heath
Some faults are in the controls rather than the fan. Speed controllers, isolators and wiring can all fail so we check the controls before blaming the motor.
Most sites get in touch when they notice one of these:
- A fan rattling in its housing
- A failed fan that needs a replacement
- A squealing belt on start-up
- A fan that will not start at all
A fan that rarely runs, like one in a hall kitchen near Church of St John the Baptist or elsewhere in Letchmore Heath, can seize between uses.
What your quote should include
- Whether they’re fully insured
- When the next visit should be, and why
- What paperwork you get at the end
- Whether VAT is included
Keeping the system healthy
A little care between visits keeps the system in better shape. Our advice:
- Keep the emergency number where staff can see it
- Report new noises from the fan early
- Keep the fan on a planned cleaning cycle
- Make sure the isolator and controls are easy to reach
Once we are done, the extract is back in service. We leave the area tidy and talk you through what we found.
A fan that’s starting to make noise is giving you a warning. Booking a check at this stage keeps it a planned job rather than an emergency during service.
When it’s something else
A few issues sit outside what this work can do:
- Faults in the building’s electrical supply, which need an electrician
- A system that needs redesigning rather than repairing
- Odour complaints that need filtration rather than a fan repair
If in doubt, give us a ring on 0345 646 2711 or send us an email and we will say what we think before you book.

Letchmore Heath: your questions answered
Do you work overnight in Letchmore Heath?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Letchmore Heath needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Who inspects food businesses in Letchmore Heath?
Kitchens in Letchmore Heath are inspected by Hertsmere council’s environmental health officers. A note of when the fan failed and when it was fixed shows the problem was dealt with.
What makes a kitchen extract fan rattle or whine?
Noise normally comes from grease build-up, bearings, belts or loose fixings. Rattles, whines and grinding point to different faults and we find the exact cause on site.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
What happens to the waste?
We take it away at the end of the visit. During the work, it’s contained so the area stays clean.
Will we have to shut during the visit?
Not typically. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.
Is TR19 a legal requirement?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
Do you offer emergency callouts?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Managing agents and facilities teams in Letchmore Heath
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
What the work involves, part by part
Motors and bearings
A grinding or rumbling noise often means worn bearings. We diagnose whether it’s the bearings or the motor itself before recommending a fix.
Fan controls
Supply faults are a job for an electrician. We’ll tell you if that’s what we find so you know who to call.
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, and that takes a few hours for most repairs, longer for a full fan replacement. If the van will struggle with a lane or gateway near Letchmore Heath, let us know and we’ll plan around it.
- We take details of the symptoms and book a time that suits the kitchen.
- On site, the fan is safely isolated.
- The fan and its controls are checked to pin down the fault.
- You get a fixed price for putting it right.
- The work is done and the fan is tested running.
Preparing for the visit
- Tell us where we can park and unload
- Let us know about permits to work or site inductions
- Move anything stored near the system
Getting a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, ring 0345 646 2711 or email us.
