Part by part
Impellers and housings
The fan housing collects grease too. We check both and cleaning may be part of the fix.
Fan controls
We check the controls as part of every diagnosis, because a fan that won’t start isn’t always a failed motor.
About our extract fan repair in Astwick
Diagnosis comes before parts. We look at the motor, the belts or direct drive, the impeller and the mountings, along with the fan’s controls. After that, you get a fixed price for what’s needed. If you have a fan shaking on its mountings and a belt-driven fan that squeals, we can help, from fan motors, belts and pulleys and kitchen extract fans onwards.
In a small place like Astwick, fans are often on an outside wall or roof, open to wind and rain. Weather and grease together wear out motors and bearings.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Questions from Astwick
Who inspects food businesses in Astwick?
That’s Central Bedfordshire council, whose environmental health officers carry out food hygiene inspections in Astwick. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.
Who do I call if an extract fan fails in Astwick?
Astwick is covered, and our emergency callout runs 24/7. Ring 0345 646 2711 at any hour and describe the fault. Tell us where the fan is and how to reach it.
What will a fan repair or replacement cost?
The cost depends on what’s wrong and how easy the fan is to reach. We diagnose first and give you a fixed price before any work starts.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
Who is the responsible person?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
What if parts of the system can’t be reached?
We record them on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
Do I get a report after the visit?
Yes, on every job. It’s a dated, written report with pictures, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. File it with your fire safety records.
When something else is needed
It’s worth knowing the limits before booking:
- 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 0345 646 2711 or use the quote form and we will say what we think.

Signs you need extract fan repair in Astwick
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 after spotting something like this:
- A humming noise from the fan motor
- A knocking noise from the extract fan
- Poor airflow at the canopy
- A fan shaking on its mountings
For school kitchens, at schools like St Mary's CofE Academy Stotfold for example, a planned fan repair in the holidays avoids losing lunches in term time.

Extract fans in Astwick
There are about 4 restaurants, cafés and works canteens and about 4 takeaways within about 1.5 miles of central Astwick, according to the Food Standards Agency’s register. Those that cook under a canopy rely on a fan that runs every hour they’re open. We cover Astwick, about 37 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included. Food hygiene inspections in Astwick are the job of Central Bedfordshire council’s environmental health team. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. So a failed fan is worth fixing before the next service, not the next month.

The process
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the extract fan repair, tidy up and leave you the report. The visit itself takes a few hours on site, depending on the fault and the access to the fan. Somewhere as small as Astwick, the date and timings are agreed with you well before the day.
- We agree a time to attend, out of hours if needed.
- The extract is switched off and the fan opened up.
- We inspect every moving part and the fixings.
- We explain the options and quote a fixed price.
- We complete the work and check the fan runs smoothly.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Tell us where we can park and unload
- Find the previous report, if there is one
Ask for a quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.

Why deal with it now?
A fan that’s running slowly is not clearing the kitchen properly. Staff work in hotter, steamier air and grease has more chance to settle on surfaces and in the duct. A fault that closes a site in a village like Astwick affects everyone who depends on it.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
Why us?
- One contact for all your sites in London and the South East
- Out-of-hours work and a 24/7 emergency line
- CHAS, SafeContractor and ISO 9001
- We are fully insured

What affects the cost of extract fan repair
We do not publish a price list, because sites vary so much. What we look at:
- The number of sites or systems
- Site requirements such as sign-in and permits
- The scale of the work
- Parking and loading at the site
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
- Photos showing the whole system and its surroundings
- When the site is open and when it’s quiet
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, ring 0345 646 2711 or drop us a line.
Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Do not cook with gaps in the filter bank
- Keep access to the fan controls unobstructed
- Report new noises from the fan early
- Note when the fan trips or cuts out
Keep an ear on the fan after the repair. If anything changes, let us know, so it can be looked at before it grows.
When filters block, the fan works harder. Keeping filters clean eases the strain and protects the motor.
