How we handle extract fan repair in Aylesbury
A faulty fan doesn’t always mean a new one. Often a clean, a new belt or new bearings brings it back, and that is what we will recommend. When a fan is worn beyond sensible repair, a replacement suited to the system goes in. Typical jobs include an extract fan that rattles or knocks and a humming noise from the fan motor, across belts and pulleys, roof and wall fans and kitchen extract fans.
Busy kitchens in a place like Aylesbury can run their extract fans for long hours, which wears out belts, bearings and motors. Grease on the impeller makes it worse, throwing it out of balance.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

FAQs for Aylesbury
Do you work at weekends in Aylesbury?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Aylesbury needn’t be disturbed. Your opening times are the first thing we ask for.
Is there an emergency callout for extract fans in Aylesbury?
Extract fan emergencies in Aylesbury are covered around the clock. Call 0345 646 2711 and tell us what the fan is doing, or not doing. Let us know whether the fan is silent, noisy or tripping the power.
Can you supply and fit a replacement fan?
Yes, when repair doesn’t make sense. We check the duct size and the extract the kitchen needs so we confirm that first.
Is TR19 a legal requirement?
No. TR19® itself isn’t law; it’s a BESA specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Can you repair a fan rather than replace it?
Repair is always our starting point. Where the motor has burnt out or the fan is worn out, replacing it can be the better answer, and we will explain why.
Do you provide a certificate or report?
Yes. It’s the record insurers and inspectors ask to see: a dated report with photos, listing the work and any areas we couldn’t reach.
Is it worth cleaning the extract while you are fixing the fan?
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 you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.

What else we do in Aylesbury
What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
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, and that’s where we come in.
What we do, step by step
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes part of a day for most faults, with a return visit if parts have to be ordered. Larger sites in Aylesbury can be done in phases, out of hours, so part of the building keeps working.
- A visit is booked, in the evening or overnight if that suits.
- The extract is switched off and the fan opened up.
- We inspect every moving part and the fixings.
- You hear whether repair or replacement makes sense, with a fixed quote.
- The fan is repaired or replaced, then checked running.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet
- Arrange a key holder or contact on site

Extract fans in Aylesbury
The FSA’s food hygiene register shows about 91 restaurants, cafés and works canteens and about 58 sandwich bars and takeaways in and around Aylesbury, up to about a mile and a half out. Wherever they cook under a canopy, a failed extract fan stops the kitchen. It’s Buckinghamshire council that sends environmental health officers to food businesses in Aylesbury. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. So a failed fan is worth fixing before the next service, not the next month. Aylesbury, about 38 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible.
A fan that rarely runs, like one in a hall kitchen near Church of St Mary or elsewhere in Aylesbury, can seize between uses. School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Buckinghamshire UTC, fix a failing fan before term starts. If you run a café or takeaway near Aylesbury station, a failed fan in the middle of service is exactly what our 24/7 emergency line is for.

Part by part
Motors and bearings
If the motor runs hot or keeps tripping, something’s wrong. The cause might be grease restricting the airflow, or the motor itself may be failing.
Direct-drive fans
Direct-drive fans are compact and common in kitchen extracts. When the motor fails, replacing the whole fan unit can make more sense than repairing it and we will talk you through it.
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Problems with the electrical supply to the fan (an electrician’s job)
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- An extract system that was undersized from the start
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think before booking.
Where we work
- Roof and wall fans
- Belts and pulleys
- Bearings
- Kitchen extract fans
- Fan housings
- Fan motors
What happens if it’s left?
Wherever the kitchen is, Aylesbury included, the fan often sits on an outside wall or roof, so its noise does not stay in the kitchen. Dealing with the fault brings the noise back down before neighbours notice. Several systems on one site in Aylesbury are simpler to look after when the dates are set in advance.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

What affects the cost of extract fan repair
The diagnosis comes before the price. The main factors are:
- Parking and loading at the site
- How many systems or sites are involved
- Site requirements such as sign-in and permits
- One-off work versus a regular cycle
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
Photos let us diagnose from a distance. Try to include:
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
- The site address and the type of premises
- The paperwork from the last visit, if you have it
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before we start.
Landlords, agents and facilities managers
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
