- An extract fan that rattles or knocks
- A fan worn beyond sensible repair
- An overheating extract motor
The process
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes anything from an hour or two to a full visit, depending on the fault. If the van will struggle with a lane or gateway near How Green, let us know and we’ll plan around it.
- You describe the fault and we arrange a visit.
- On site, the fan is safely isolated.
- 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
- Allow time for equipment near the work to be turned off and cool down
- Dig out any earlier paperwork for the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Ask for a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

About our extract fan repair in How Green
Working on a fan in How Green means switching the extract off first, so the job is fitted around the kitchen’s hours. We can work in the evening, overnight or at the weekend and there’s a 24/7 emergency line if the fan fails while you’re cooking. If you have a motor that trips out or overheats and a belt-driven fan that squeals, we can put it right.
Somewhere as small as How Green, 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.
A written report with pictures follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What happens if it’s left?
Some kitchens run a noisy fan on a lower speed to cut the noise. It hides the symptom and weakens the extract while the underlying wear continues. A proper diagnosis in How Green gets to the real cause. In a place like How Green, ductwork and fans are easy to forget until something goes wrong.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Why us?
- We’re fully insured
- We diagnose before we treat
- Photo reports with every job
- Fixed quotes from a survey or photos

Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Make sure the fan is cleaned with the rest of the system
- Avoid lowering the speed to quieten a fault
- Keep access to the fan controls unobstructed
- Keep all filters fitted while cooking
If parts have to be ordered, we tell you how the kitchen can carry on in the meantime. We then come back and fit them outside your busiest hours.
Regular TR19 cleaning includes the extract fan. Keeping grease off the impeller is one of the simplest ways to protect it, so planned cleaning helps the fan last.
Different parts, different methods
Impellers and housings
A damaged or corroded impeller cannot simply be cleaned. It may be replaced on its own, or with the whole fan.
Roof and wall-mounted fans
Fans outside are exposed to rain and condensation. Rust on fixings and housings is a frequent find.
What extract fan repair looks like in How Green
Food Standards Agency records list about 4 restaurants, cafés and canteens within 1.5 miles or so of the middle of How Green. Every one of them that cooks under a canopy depends on its extract fan to keep cooking. Food hygiene inspections in How Green are the job of Sevenoaks 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. How Green, about 23 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible.
If you run a school kitchen, at a school such as Hever Church of England Voluntary Aided Primary School or nearby, a fan that is getting noisy is best repaired in the holidays before it fails in term. A fan that rarely runs, like one in a hall kitchen near Church of St Peter or elsewhere in How Green, can seize between uses.

What affects the cost of extract fan repair
A fixed price needs a few facts first. We look at:
- When the work can happen, such as evenings, overnight or weekends
- The condition we find in the survey
- Parking and loading at the site
- Whether it’s a one-off visit or part of a schedule
We do not list prices on the website, because each job is priced on what it involves. For a fixed quote, ring 0345 646 2711 or email us, and we will talk you through it.
Asking for a quote
You do not need the technical terms. Just send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
- A few general shots of the system
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711, or send details by email.
Staff cleaning versus specialist work
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, next to our reports.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
When it’s something else
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
- An extract system that was undersized from the start
- Cooking smells reaching neighbours, which may need odour control
Not sure which it is? You can call 0345 646 2711, or email photos and we will tell you honestly before you book.
What the work covers
- Belts and pulleys
- Fan motors

Questions from How Green
Who inspects food businesses in How Green?
That’s Sevenoaks council, whose environmental health officers carry out food hygiene inspections in How Green. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.
Can you come to How Green after we close?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in How Green needn’t be disturbed. Tell us your opening hours when you ask for a quote.
What causes a noisy extract fan?
Noise normally comes from grease build-up, bearings, belts or loose fixings. Each sounds a little different, and we diagnose it on site.
Which accreditations do you hold?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Will you tell us when the next visit is due?
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, while fire dampers are tested at least annually.
Will you fit a new fan if ours can’t be repaired?
Yes. If repair isn’t sensible, we replace the fan. We check the duct size and the extract the kitchen needs before recommending a unit.
What happens if you cannot reach some of it?
Anything we can’t reach goes on the report, with photos where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
