About our extract fan cleaning in Knockholt

Is the extract fan louder than it used to be, or the airflow weaker? Tell us about it when you call us on 0345 646 2711 or send us an email, and you will get a fixed price, typically within one working day. The work covers axial fans, fan housings and in-line fans, and the jobs we see most are a fan that hums, whines or rumbles and burning smells from the fan area.

In a village or hamlet like Knockholt, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease.

The paperwork matters as much as the work. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Extract fan cleaning in Knockholt: the local picture

Food hygiene inspections in Knockholt are the job of Sevenoaks council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Knockholt falls to Kent Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

If you run catering at a healthcare site, such as a hospital like Orpington Hospital about 3.6 miles north, the extract may need cleaning more often than a part-time kitchen. Down House, about 2.7 miles north-west, is one of the historic houses near Knockholt; if you run event catering at a venue like that, cleans can be booked between functions.

In-house cleaning or a specialist?

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.

Your questions about extract fan cleaning in Knockholt

Do you work in villages like Knockholt?

Yes, we work in villages as well as towns, and Knockholt is covered. The journey is planned ahead, so a few details about the route help.

Which fire authority looks after Knockholt?

It’s Kent Fire and Rescue Service, which covers Knockholt. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

Who is the responsible person?

The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.

Is it safe to clean the fan while the kitchen is open?

With the fan isolated, the extract is not running. We work evenings, overnight or weekends, and the kitchen is ready when we leave.

What accreditations do you have?

BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we are fully insured.

How much notice should we give?

It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.

How much does extract fan cleaning cost?

Every site is different, so each gets its own fixed quote. For a quote, give us a ring on 0345 646 2711 or send us an email with the site type, opening hours and a few pictures.

What happens if you cannot reach some of it?

They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.

Keeping the system healthy

To keep the system working properly between visits:

  • File the fan’s report with your other records
  • Check filters are seated before cooking
  • Report grease escaping from the fan
  • Listen for new noises or vibration from the fan

When we’ve finished, the fan is reassembled and run. If anything seems wrong, from vibration to wear, we note it, so you can plan any repair.

Fewer grease particles reaching the fan means less build-up. Keep the grease filters clean, fitted and in place, and replace any that are damaged.

Part by part

Impellers and blades

Grease on the leading edges of the blades cuts the fan’s efficiency. We clean each blade back to its surface, so the fan can run as intended.

Fan housings and motors

We clean around the motor without soaking its electrics, and the fan is isolated throughout. Grease on and around the motor can trap heat, so the surrounding area is cleaned carefully.

Why deal with it now?

A greasy fan at the discharge can spread grease onto the roof or wall around it. It marks the area around the outlet and leaves more fuel outside, which is one more reason to keep it clean. In a place like Knockholt, ductwork and fans are easy to forget until something goes wrong.

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, phone us on 0345 646 2711, or email photos for straight advice and a fixed quote.

How it works

Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes an hour or two for one fan, longer when it’s hard to reach. Seeing the system in photos first means the trip to Knockholt can be planned properly.

  1. We start by checking where the fan sits and how to isolate it.
  2. With the fan isolated, the housing is opened.
  3. Grease is scraped from the impeller blades and the inside of the housing.
  4. The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
  5. We reassemble, run the fan and photograph the result.

How to prepare

  • Mention any locked doors, roof access or ceiling voids
  • Let us know about permits to work or site inductions
  • Mention any parking or loading restrictions

Common problems we fix in Knockholt

Grease on a fan is a fire risk, in Knockholt as anywhere. If grease in the duct catches, the fan and its housing can feed the fire, and a hot, struggling motor does not help.

Common reasons sites call us are:

  • Weak extraction at the canopy
  • A noisy fan that has got louder over time
  • An extract fan with no cleaning record
  • Grease escaping from the fan outlet

Where a hall near St Katharine's Church, or anywhere in Knockholt, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
