How we handle extract fan repair in Greenhill
Across Greenhill, we deal with fan faults of every kind, from rattling and humming to a fan that has stopped dead. The fault is diagnosed, quoted at a fixed price and put right, or the fan is replaced if repair doesn’t make sense. If you have vibration spreading from the fan into the ducts and an extract fan that has stopped working, we can help, from fan housings, kitchen extract fans and fan motors onwards.
Replacing a fan in a London building often means working at height or in a tight plant space, and in Greenhill, parking and lifting are part of that. Work can be done after service, so the kitchen loses as little time as possible.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What extract fan repair can’t fix
We’ll always give you a straight diagnosis, so here’s what this work cannot put right:
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- Grease build-up in the rest of the extract system
- An extract system that was undersized from the start

Common questions in Greenhill
Is there an emergency callout for extract fans in Greenhill?
Greenhill is covered, and our emergency callout runs 24/7. The number to ring is 0345 646 2711. Tell us where the fan is and how to reach it.
Who would carry out a food hygiene inspection at a kitchen in Greenhill?
Food hygiene inspections in Greenhill are carried out by Camden council. Keeping the fan serviced is easier than explaining a broken one on inspection day.
How much time does a fan repair need?
As a guide, it takes a few hours on site, depending on the fault and the access to the fan. Where parts need ordering, we will explain the timescale.
Does a fan repair include cleaning the ductwork?
Doing both together is often sensible. A TR19 clean covers the canopy, plenum, ductwork and fan, with a certificate and photo report.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Will you tell us when the next visit is due?
Yes. The interval depends on how much the system is used and what we find and the report sets out why.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Does a faulty extract fan always need replacing?
It depends on the fault. After diagnosing, we explain whether it can be repaired and quote a fixed price for the option you choose.
Common problems we fix in Greenhill
In Greenhill, 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 are:
- A fan rattling in its housing
- A motor that trips out or overheats
- A dead fan motor
- A fan running too slowly to clear the kitchen
School kitchens can’t easily serve lunch without extraction, so if you look after one at a school like The Royal School, fix a failing fan before term starts.
Questions to ask before you book
- Whether the figure could change on the day
- How areas they cannot reach will be recorded
- Whether they’re fully insured
- Exactly which parts of the system are covered
What affects the cost of extract fan repair
There’s no set price list, because sites vary so much. The quote depends on:
- The times the site is available
- A single visit or a regular plan
- Where the site is and how we reach it
- How easy every part is to reach
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before work begins.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Detail shots of panels, filters and grilles
- Your last certificate, test record or report
- Wide pictures of the system and the area around it
- Problems your staff have spotted
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
What we do, step by step
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes an hour or two to diagnose, then longer if parts or a new fan are needed. Expect the work in Greenhill to happen after your last customer leaves, not during trading.
- 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.
- A fixed quote for the repair or replacement follows.
- We fix the fault and run the fan to check it.
Preparing for the visit
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down
- Make sure someone can let us in and lock up afterwards
Ask for a quote
For a fixed quote, call 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We typically come back within one working day.
Advice
How the job changes from site to site
Roof and wall-mounted fans
Fans outside are exposed to rain and condensation. Corrosion of housings and fixings is common.
Motors and bearings
Motors and bearings take the most strain in a kitchen extract fan. Heat, grease and long running hours all wear them.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Make sure every filter is in place and clean
- Write down when the fan misbehaves
- Keep the area around the fan controls clear
- Keep the emergency number where staff can see it
Grease on the fan usually means grease in the duct as well. A full TR19® clean deals with the canopy, ductwork and fan together, with a certificate and photo report.
A scheduled maintenance plan keeps the whole system on a regular cycle, so the fan is looked at as part of each visit and problems are spotted sooner.
In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

What else we do in Greenhill
What extract fan repair looks like in Greenhill
There are about 617 cafés, restaurants and staff canteens and about 268 takeaways in and around Greenhill, up to about a mile and a half out, according to the Food Standards Agency’s register. Wherever they cook under a canopy, a failed extract fan stops the kitchen. London extract fans are often at the end of long duct runs, on roofs or in basements. Food hygiene inspections in Greenhill are the job of Camden council’s environmental health team. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. Getting the fan running again is the priority.
A fan that rarely runs, like one in a hall kitchen near Rosslyn Hill Unitarian Chapel or elsewhere in Greenhill, can seize between uses. For kitchens close to Hampstead Heath station, a fan that stops mid-service needs fixing fast, and our emergency line runs 24/7.
