About our extract fan cleaning in Greenhithe
The extract fan is the heart of the system: it pulls air from the canopy, through the duct and out of the building. Grease that gets past everything else ends up on its blades and housing and we clean it off. The work covers axial fans, roof-mounted fans and fan housings, and people most often call us about an extract fan with no cleaning record and rough running from the extract fan.
Kitchens around a place like Greenhithe are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Extract fan cleaning around Greenhithe
The FSA’s food hygiene register includes about 11 pubs and bars in Greenhithe and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Kent Fire and Rescue Service covers Greenhithe. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Environmental health officers from Dartford council inspect food businesses in Greenhithe. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
If you run a café or takeaway near Greenhithe for Bluewater station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. A hospital like Darent Valley Hospital, about 1.5 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Where a hall near Church of St Mary, or anywhere in Greenhithe, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Questions from Greenhithe
Can a school canteen extract in Greenhithe be done out of term time?
Yes, holiday work suits schools best. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Greenhithe. You can ring 0345 646 2711, or email photos with the dates the site is empty.
Who would carry out a food hygiene inspection at a kitchen in Greenhithe?
That is Dartford council, whose environmental health officers carry out food hygiene inspections in Greenhithe. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Why is my extract fan noisy?
Uneven grease on the impeller often causes it. We clean the fan and tell you if anything else, like worn bearings, is to blame.
How much does extract fan cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, normally ready within one working day.
Do we lose a day’s trading?
Not typically. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
Can you fix a fan that is worn out?
Cleaning removes grease, but it can’t fix worn parts. Where the fan needs repair or replacement, we can do that too, with a fixed quote first.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
Do you cover Greenhithe?
Yes. We work in Greenhithe and the rest of Kent, as part of our work across South East England and London. To book, call 0345 646 2711, or send details by email.
When it’s something else
It’s worth knowing the limits before booking:

- Wiring faults to the fan

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
The process
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes a couple of hours per fan, depending on its size and the build-up. Everything the job in Greenhithe needs is worked out beforehand, from the survey.
- The fan is found and its type, access and isolation checked.
- We isolate the power before opening the housing.
- We scrape the heavy grease from the blades and housing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
How to prepare
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
- Let us know about permits to work or site inductions

Advice
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Don’t store items in front of the fan’s access point
- Report rattles or humming early
- Watch for grease marks around the outlet
- Keep the grease filters clean and in place
File the photo report with your other extract records. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
Do not run the kitchen with the extract off. Grease settles faster when the air stops moving, so keeping it running helps keep it clean.
Different parts, different methods
Inline duct fans
Hidden in a ceiling void, an inline fan is easily missed. We find it during the survey and include it in the clean.
Fan housings and motors
We clean around the motor without soaking its electrics, and the fan is isolated throughout. Grease around the motor can make it run hotter, so we clean what we safely can.
Why it’s worth doing now in Greenhithe
Grease on a roof fan can also escape outside. That stains surfaces and can add to the fire risk outside the building, which is one more reason to keep it clean. Systems on quieter sites still build up dirt and wear, just more slowly.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
