About our extract fan cleaning in Chevening

The extract fan is the heart of the system: it draws the air through the canopy and ductwork and pushes it outside. Whatever grease slips past the filters and duct reaches the fan, and that is what we clean. The work covers roof-mounted fans, axial fans and discharge points, and common reasons people get in touch are a fan that hums, whines or rumbles and a motor area thick with grease.

Somewhere as small as Chevening, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.

Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

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 it goes on the report too. The visit takes an hour or two for one fan, longer when it’s hard to reach. If you can send photos, we can arrive in Chevening knowing what to expect.

  1. We find the fan and check how it’s reached and how it’s isolated.
  2. Power to the fan is isolated before anyone touches it.
  3. We remove the grease from the blades, impeller and casing.
  4. The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
  5. It’s closed up, run and checked, and pictures go into your report.

How to prepare

  • Agree a time when the area can be out of use
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Have your last certificate or report to hand

How to get a quote

To get a fixed quote, phone us on 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 photos and your last certificate or report help a lot. We usually come back within one working day.

Extract fan cleaning around Chevening

According to Food Standards Agency records, there are about 6 bars, pubs and nightclubs within roughly a mile and a half of the centre of Chevening. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Chevening, food businesses are inspected by environmental health officers from Sevenoaks council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. The fire and rescue service for Chevening is Kent Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.

If you look after a school kitchen, at a school such as Combe Bank School or anywhere near Chevening, the holidays are the usual time for a TR19® clean. A hall kitchen that only cooks for events, whether near Church of St Botolph or elsewhere in Chevening, still needs its extract cleaned, just less often.

Chevening is about 3 miles north-west of Sevenoaks, in Kent. Every kind of commercial site in Chevening, extract fan cleaning is something we can help with.

Why it’s worth doing now in Chevening

A greasy fan has to work harder to move the same air. Airflow at the canopy drops and the kitchen gets hotter and smokier, while the motor runs under more strain. With notice, the visit to Chevening can be fitted around your bookings and events.

Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

What we’re called out for in Chevening

By the time air reaches the fan, it has passed the canopy, filters and duct. Whatever grease is still in it settles on the impeller and inside the housing where the spinning blades spread it around.

Signs it’s time to call us include:

  • Hot, greasy smells near the fan
  • An extract fan with no cleaning record
  • A heavily greased fan housing
  • An extract fan that vibrates or rattles

Healthcare kitchens, like those at hospitals such as Sevenoaks Hospital (about 2.8 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.

What your quote should include

  • What insurance they carry
  • If the quote is a fixed price or an estimate
  • When the next visit should be, and why
  • Whether inaccessible sections are listed on the report

Our hiring checklist

What the work involves, part by part

Roof-mounted fans

A roof fan sits in cooler air, so grease can settle heavily. We scrape and degrease the blades and casing.

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.

Keeping the system healthy

To keep the system working properly between visits:

  • Leave a clear route to the fan
  • Keep each photo report with the maintenance log
  • Don’t turn the fan off mid-service
  • Check filters are seated before cooking

The area around the fan is left clean, with waste grease removed. Wherever the fan is, the area around it is cleaned down.

Fewer grease particles reaching the fan means less build-up. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.

How we price extract fan cleaning

We quote each job individually. This is what makes a difference:

  • The times the site is available
  • Site requirements such as sign-in and permits
  • What state the system is in
  • Whether it’s a one-off visit or part of a schedule

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

What we need to know

To speed up the quote, please include:

  • A few general shots of the system
  • The paperwork from the last visit, if you have it
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • The postcode and the type of business

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, give us a ring on 0345 646 2711 or drop us a line.

When something else is needed

We’d rather tell you now than book work that will not help, so here are the limits:

  • Electrical faults in the fan’s supply or controls (an electrician’s job)
  • Grease in the duct and canopy before the fan (those need a full TR19 clean)
  • A fan that will not start

Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we’ll tell you honestly.

What the work covers

  • Discharge points
  • Roof-mounted fans
  • Fan housings
  • In-line fans
  • Axial fans
  • Centrifugal fans

Chevening questions

Which fire and rescue service is responsible for Chevening?

Kent Fire and Rescue Service is the fire and rescue service for Chevening. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

Can you come to Chevening after we close?

Yes, out-of-hours work is a big part of what we do. That way a site in Chevening does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.

How long is a fan clean?

It takes an hour or two for most single fans. Your quote will give an idea.

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.

What types of premises do you cover?

Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

Why has my extract fan got louder?

A common cause is grease. Uneven build-up on the blades throws the fan off balance, causing vibration and noise. If cleaning doesn’t, the bearings or motor may need attention.

Should the extract fan be cleaned as part of TR19?

Yes. The whole system is cleaned, from the canopy to the discharge, and the fan is a key part of it, so it’s cleaned too.

How do you protect the area?

Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
