When a fan fails in Datchworth
Food Standards Agency records list about 6 cafés, restaurants and staff canteens within roughly a mile and a half of the centre of Datchworth. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. It’s East Hertfordshire council that sends environmental health officers to food businesses in Datchworth. 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. Datchworth, about 25 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours.
School kitchens can’t easily serve lunch without extraction, so if you look after one at a school like St Michael's Woolmer Green CofE VA Primary School, fix a failing fan before term starts.

How it works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes an hour or two to diagnose, then longer if parts or a new fan are needed. In a small place like Datchworth, the journey is planned ahead and the visit arranged around the site’s hours.
- We agree a time to attend, out of hours if needed.
- We isolate the extract and open the fan housing.
- We inspect every moving part and the fixings.
- We explain the options and quote a fixed price.
- The fan is repaired or replaced, then checked running.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Allow time for equipment near the work to be turned off and cool down
- Clear the space around the work
Ask for a quote
We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To start, call us on 0345 646 2711 or use the quote form.
Advice
What we’re called out for in Datchworth
Fan bearings don’t last for ever, especially in a hot, greasy airstream. As they wear, you hear a whine or a rumble and a seized bearing stops the fan.
If you notice any of these, it’s worth a diagnosis:
- A fan running too slowly to clear the kitchen
- A failed fan that needs a replacement
- A motor that trips out or overheats
- A squealing belt on start-up
If you look after a church or hall kitchen near Church of All Saints, or anywhere in Datchworth, test the extract fan before a big event rather than on the day.

FAQs for Datchworth
Can you come to Datchworth after we close?
Yes, evening, overnight and weekend work is normal for us. It means the site in Datchworth keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Which council inspects kitchens in Datchworth?
The local authority for Datchworth is East Hertfordshire council, and its environmental health team does the inspecting. If the extract fan has failed, it’s worth having the repair booked, and the details to hand, before an officer visits.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
Will you fit a new fan if ours can’t be repaired?
Yes. We fit replacement fans as well as repairing old ones, and we will explain the options.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Does a fan repair include cleaning the ductwork?
Often it makes sense to do both. A TR19 clean covers the canopy, plenum, ductwork and fan and comes with a TR19 certificate and photo report.
Do we lose a day’s trading?
Not usually. 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.
What makes a kitchen extract fan rattle or whine?
Noise normally comes from grease build-up, bearings, belts or loose fixings. Each sounds a little different and we find the exact cause on site.
Managing agents and facilities teams in Datchworth
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
What affects the cost of extract fan repair
We quote each job individually. This is what makes a difference:
- Whether we need access equipment or extra panels
- How big the system is
- How many systems or sites are involved
- A single visit or a regular plan
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before we start.
What to send for a quote
Many jobs can be priced from photos and some basics. Useful things to send:
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
- Any access panels or hatches you can see
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Once you have those, phone us on 0345 646 2711, or email photos.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Leave it or put it right?
It can be tempting to turn the fan down to quieten it. It hides the symptom and weakens the extract while the underlying wear continues. Diagnosing the fault properly is the lasting answer. Systems in rural buildings are often out of sight and out of mind.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.

Between visits
Good habits slow the build-up between visits. A few tips:
- Keep a record of any trips or stoppages
- Get a noisy fan checked rather than slowed down
- Don’t wait for a noisy fan to stop
- Make sure the isolator and controls are easy to reach
Keep an ear on the fan after the repair. If anything changes, let us know rather than waiting for it to fail.
The fan is part of every full TR19 clean. Keeping grease off the impeller is one of the simplest ways to protect it, so planned cleaning helps the fan last.
