Extract fan repair in Thorley Street
Extract fan repair starts with a diagnosis. Noise can come from grease on the impeller, worn bearings or a slipping belt, while a fan that will not start may have a motor or control fault. We explain the problem, and what it will take, before we start. Common call-outs are for a fan that won’t start at all and a fan worn beyond sensible repair, across kitchen extract fans, belts and pulleys and fan housings.
Rural kitchens often have fans mounted on outside walls or roofs, exposed to the weather. Weather and grease together wear out motors and bearings.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

When a fan fails in Thorley Street
Food Standards Agency data counts about 86 restaurants, cafés and works canteens and about 29 takeaways within roughly a mile and a half of the centre of Thorley Street. For any of them with a canopy, the extract fan is what keeps the kitchen usable. Thorley Street, about 27 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you. It’s East Hertfordshire council that sends environmental health officers to food businesses in Thorley Street. Food hygiene rules expect food premises to have suitable and sufficient ventilation. So a failed fan is worth fixing before the next service, not the next month.
If you run a church or community hall kitchen, near Parish Church of St James the Great or elsewhere in Thorley Street, an extract fan that rarely runs can seize or fail when it’s needed.

In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Your questions about extract fan repair in Thorley Street
Can you get to a site in Thorley Street?
Yes, we work in villages as well as towns, and Thorley Street is covered. Photos of the system and directions to the site help us plan the visit.
Do you cover Thorley Street for emergency fan repairs?
We run a 24/7 emergency line for failed extract fans, and Thorley Street is part of our area. The number to ring is 0345 646 2711. If you can, stop cooking until the fan is checked.
Will you fit a new fan if ours cannot be repaired?
Yes, when repair doesn’t make sense. We check the duct size and the extract the kitchen needs so we confirm that first.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Can you tell me the price of a fan repair?
The cost depends on what’s wrong and how easy the fan is to reach. We diagnose first and give you a fixed price so there are no surprises.
Should the fan be cleaned as well as repaired?
Often it makes sense to do both. A TR19 clean covers the canopy, plenum, ductwork and fan, with a certificate and photo report.
What makes a kitchen extract fan rattle or whine?
Noise usually 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.
Are you insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Keeping the system healthy
Once we have finished, these simple steps help:
- Report new noises from the fan early
- Write down when the fan misbehaves
- Keep the area around the fan controls clear
- Don’t cook with gaps in the filter bank
If the fan had grease on it, the rest of the system almost certainly does too. We can book a TR19® clean of the whole extract and you get a TR19 certificate and photo report afterwards.
A slipping belt or a loose mount is a small job. Ignored, they can lead to bigger failures, so it’s worth acting early.
Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
When it’s something else
Some problems need a different service or another trade:
- Smells from the discharge that need odour control equipment
- Problems with the gas supply or its interlock valve
- Problems with the electrical supply to the fan (an electrician’s job)
If in doubt, phone us on 0345 646 2711, or email photos and we’ll say what we think before you book.

- You describe the fault and we arrange a visit.
- On site, the fan is safely isolated.

Related advice
What we are called out for in Thorley Street
When filters clog and ducts fill with grease, the fan has to strain. A motor that strains runs hot, trips out or eventually burns out.
These are the problems we see most often:
- A failed fan that needs a replacement
- A knocking noise from the extract fan
- A squealing belt on start-up
- A humming noise from the fan motor
School kitchens can’t easily serve lunch without extraction, so if you look after one at a school like Thorley Hill Primary School, fix a failing fan before term starts.
