About our extract fan repair in Cow Roast
Across Cow Roast, we deal with fan faults of every kind, from a squeal at start-up to a fan that will not run at all. We find the cause, give you a fixed price and fix it, or the fan is replaced if repair does not make sense. The work covers belts and pulleys, roof and wall fans and bearings, and the jobs we see most are a belt-driven fan that squeals and an overheating extract motor.
In a village or hamlet like Cow Roast, the kitchens with extract fans are few, wherever there are any. A failed fan stops the kitchen, and emergency callout is available 24/7, villages included.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What happens if it’s left?
A fan that’s running slowly is not clearing the kitchen properly. Staff work in hotter, steamier air, and more grease settles where it shouldn’t. In a place like Cow Roast, ductwork and fans are easy to forget until something goes wrong.
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711 or send us an email, and we will talk you through it.

Aftercare tips
Think of this as the after-treatment advice, in brief:
- Do not cook with gaps in the filter bank
- Don’t turn the fan down to hide a noise
- Book regular TR19 cleaning, which includes the fan
- Make sure the isolator and controls are easy to reach
Once the fan is running smoothly, keep the filters clean. Less grease on the impeller means less wear and fewer faults.
Noise is typically the first sign of a fan problem. Booking a check at this stage keeps it a planned job rather than an emergency during service.
What the work involves, part by part
Fan controls
Where the fault is in the building’s electrical supply, an electrician is needed. We will tell you if that’s what we find so you know who to call.
Motors and bearings
Motors and bearings take the most strain in a kitchen extract fan. Hot, greasy air and long days wear them down.
How it works
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes a few hours on site, depending on the fault and the access to the fan. Somewhere as small as Cow Roast, the date and timings are agreed with you well before the day.
- You describe the fault and we arrange a visit.
- We isolate the fan before touching it.
- We diagnose the fault, checking the controls as well as the fan.
- A fixed quote for the repair or replacement follows.
- The work is done and the fan is tested running.
Before we arrive
- Mention any sign-in, permit or induction we need
- Let us know when the site is closed or quiet
- Plan for cooking equipment or plant to be off before we arrive

FAQs for Cow Roast
Who carries out food hygiene inspections in Cow Roast?
Food hygiene inspections in Cow Roast are carried out by Dacorum council. A note of when the fan failed and when it was fixed shows the problem was dealt with.
Do you cover Cow Roast for emergency fan repairs?
Cow Roast is covered, and our emergency callout runs 24/7. Call 0345 646 2711 and tell us what the fan is doing, or not doing. If you can, stop cooking until the fan is checked.
Can you repair a fan rather than replace it?
Often, yes. Many faults are fixed by cleaning the impeller or renewing worn parts and we only recommend replacement when repair does not make sense.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Do you recommend a next date?
Yes. We put a recommended next date on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, and fire dampers need testing at least once a year.
Managing agents and facilities teams in Cow Roast
We also work for facilities teams across offices, schools and healthcare in Cow Roast and across Hertfordshire. Larger estates can be phased building by building to keep disruption down.
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. Where responsibility is shared, records matter even more.
What we are called out for in Cow Roast
In Cow Roast, as anywhere, long cooking days mean long hours for the fan. Belts on a belt-driven fan stretch and wear and a slipping belt means slower fan speed and weaker extraction.
Common reasons sites call us include:
- A fan that won’t start at all
- An extract that vibrates through the ductwork
- A knocking noise from the extract fan
- A whining or grinding extract motor
A fan that rarely runs, like one in a hall kitchen near Church of St Bartholomew (church of England) or elsewhere in Cow Roast, can seize between uses.
Questions to ask before you book
- Whether they’re fully insured
- Whether a written report and photos are included
- Whether the quote is based on a survey or photos
- Whether the whole system is included, or only the parts that are easy to reach
