Extract fan repair in Derringstone
Across Derringstone, we deal with fan faults of every kind, from rattling and humming to a fan that has stopped dead. We find the cause, give you a fixed price and fix it or fit a replacement when it’s beyond repair. Common call-outs are for a fan that won’t start at all and a humming noise from the fan motor, across bearings, fan motors and kitchen extract fans.
Somewhere as small as Derringstone, a kitchen extract fan might serve a pub, a school, a care home or a hall kitchen. When one fails, the cooking stops, and emergency callout is available 24/7, villages included.
Good records are part of the job. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

How the job changes from site to site
Impellers and housings
The fan housing collects grease too. We check both and cleaning may be part of the fix.
Roof and wall-mounted fans
Noise from an outside fan can carry beyond the kitchen. Loose fixings and worn mounts are often the cause.
The process
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes a few hours for most repairs, longer for a full fan replacement. Pictures of the system and its access let us plan the work in Derringstone before we set off.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- The fan is isolated and opened up so we can see inside.
- The impeller, bearings, belts or drive, motor and mounts are all inspected.
- We explain the fault and give you a fixed price for the fix.
- We fix or replace the fan, then test it running before we leave.
Getting ready for the visit
- Tell us where we can park and unload
- Have your last certificate or report to hand
- Let us know how we reach the system, including roofs, risers and plant rooms

What staff can safely do
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, next to our reports.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Between visits
Once we have finished, these simple steps help:
- Tell us about a new rattle or whine right away
- Keep access to the fan controls unobstructed
- Keep all filters fitted while cooking
- Save our number for the 24/7 emergency line
Keep an ear on the fan after the repair. If anything changes, let us know, so it can be looked at before it grows.
Clogged filters make the fan strain. Keeping filters clean eases the strain and protects the motor.
What extract fan repair looks like in Derringstone
There are about 3 restaurants, cafés and works canteens within about 1.5 miles of central Derringstone, according to the Food Standards Agency’s register. Wherever they cook under a canopy, a failed extract fan stops the kitchen. We cover Derringstone, about 58 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours. Environmental health officers from Canterbury City council inspect food businesses in Derringstone. 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.
School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Barham Church of England Primary School, fix a failing fan before term starts.

What extract fan repair can’t fix
In fairness, some problems need a different fix:
- Gas interlock faults that a Gas Safe registered engineer must deal with
- Wiring and supply faults beyond the fan itself
- Grease throughout the ductwork, which needs a full TR19 clean

Derringstone questions
Is Derringstone within the area you cover?
Yes. Derringstone is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Which council inspects kitchens in Derringstone?
The local authority for Derringstone is Canterbury City council, and its environmental health team does the inspecting. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
Are you fully insured?
Yes. We’re fully insured, and we can share the details when you need them.
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 don’t leave it behind.
Does the report say when we need you again?
Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, while fire dampers are tested at least annually.
Is there help out of hours when the extract fails?
We provide a 24/7 emergency callout. Cooking without working extraction isn’t sensible so we’ll work to get it back in service.
Does a faulty extract fan always need replacing?
In many cases, yes. Many faults are fixed by cleaning the impeller or renewing worn parts, and we will always say when repair makes sense.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we’re fully insured.
What we’re called out for in Derringstone
Some grease always slips past the filters and reaches the fan. Deposits gather on the blades, never quite evenly, so the fan runs out of balance and starts to vibrate and rattle.
Clients usually contact us after spotting something like this:
- A dead fan motor
- A whining or grinding extract motor
- A squealing belt on start-up
- An extract that vibrates through the ductwork
If you run a church or community hall kitchen, near Church of St John the Baptist or elsewhere in Derringstone, an extract fan that rarely runs can seize or fail when it’s needed.
Questions to ask before booking
- Whether the work can be done while the site is closed
