How we handle extract fan repair in Colney Heath
Not every failed fan needs replacing. Sometimes cleaning the impeller or renewing worn parts is enough, and that’s what we’ll recommend. When a fan is worn beyond sensible repair, we fit a replacement matched to the duct and the kitchen. If you’re dealing with a motor that trips out or overheats and weak extraction and a smoky kitchen, we can help.
Somewhere as small as Colney Heath, a kitchen extract fan might serve a pub, a school, a care home or a hall kitchen. A failed fan stops the kitchen, and emergency callout is available 24/7, villages included.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too in Colney Heath and across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
What affects the cost of extract fan repair
We quote each job individually. This is what makes a difference:
- The times the site is available
- Whether we need access equipment or extra panels
- Site requirements such as sign-in and permits
- Parking and loading at the site
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
What to send for a quote
We can often survey from pictures. The most useful are:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Photos showing the whole system and its surroundings
- The site address and the type of premises
- Detail shots of panels, filters and grilles
To help us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Then phone us on 0345 646 2711 or send us an email.
What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes anything from an hour or two to a full visit, depending on the fault. If you can send pictures, we can arrive in Colney Heath knowing what to expect.
- 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.
- You get a fixed price for putting it right.
- The work is done and the fan is tested running.
Getting ready for the visit
- Let us know about parking and loading
- Make sure someone can let us in and lock up afterwards
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

When something else is needed
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Grease throughout the ductwork, which needs a full TR19 clean
- Faults in the building’s electrical supply, which need an electrician
- Odour complaints that need filtration rather than a fan repair
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly before booking.

What extract fan repair looks like in Colney Heath
Look up Colney Heath on the FSA’s food hygiene register and you’ll find about 37 cafés, restaurants and staff canteens and about 14 takeaways and sandwich shops within roughly a mile and a half of the centre of Colney Heath. For any of them with a canopy, the extract fan is what keeps the kitchen usable. In Colney Heath, food businesses are inspected by environmental health officers from St Albans City council. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. That makes a fan repair urgent rather than something to put off. About 18 miles out from central London, Colney Heath is part of the South East area we work across. The visit is fixed around your opening hours, not ours.
If you look after a church or hall kitchen near Church of St Mark, or anywhere in Colney Heath, test the extract fan before a big event rather than on the day.

Staff cleaning versus specialist work
When your team notices a problem 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 can diagnose it and quote.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Your questions about extract fan repair in Colney Heath
Do you work in villages like Colney Heath?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Do you work overnight in Colney Heath?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Colney Heath needn’t be disturbed. Tell us your opening hours when you ask for a quote.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Can you tell me the price of a fan repair?
We price each job after finding the cause. A belt and a new fan are very different jobs so the first step is a diagnosis.
How long does an extract fan repair take?
Typically, a fan repair takes a few hours for most repairs, longer for a full fan replacement. Where parts need ordering, we’ll explain the timescale.
Does the law say we must follow TR19?
No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.

What we are called out for in Colney Heath
When filters clog and ducts fill with grease, the fan has to strain. An overworked motor overheats and may cut out or fail.
These are the problems we see most often:
- An extract fan that has stopped working
- Poor airflow at the canopy
- Vibration spreading from the fan into the ducts
- A worn or slipping fan belt
Holidays are the time to replace a tired kitchen fan at schools such as Colney Heath Junior Mixed Infant and Nursery School, rather than mid-term.
What your quote should include
- Whether the figure could change on the day
- Whether the work can be done while the site is closed
- Whether the whole system is included, or only the parts that are easy to reach
- What records you’ll receive afterwards
Part by part
Motors and bearings
An overheating motor is a warning sign. It may be straining against blocked filters or ducts, or the motor itself may be failing.
Belt-driven fans
In a belt-driven fan, the motor drives the impeller by belt. Belts wear, stretch and slip, and pulleys and bearings need checking too.
