Why act early in Greatness

Without a working extract fan, a kitchen cannot cook safely. Grease is often where fan trouble begins, so keeping it clean is part of keeping it running. If it does fail, our 24/7 emergency line is there. When a site near Greatness shuts unexpectedly, the people who rely on it notice at once.

What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before we start.

Extract fan cleaning in Greatness, done properly

Every kitchen extract depends on its fan: 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 in-line fans, axial fans and roof-mounted fans, and the jobs we see most are an extract fan with no cleaning record and thick grease on the impeller and casing.

Size does not change the work: a kitchen in a place like Greatness gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What a clean will not put right

Extract fan cleaning can’t fix everything, and we’d rather say so up front. It does not solve:

  • Wiring faults to the fan
  • A fan that was never right for the kitchen
  • A cracked or broken impeller (it needs replacing)

Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we will tell you honestly before booking.

Where we work

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

For landlords and multi-site operators

We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.

We also work for facilities teams across offices, schools and healthcare across Kent. Work can be phased by floor, building or site to keep disruption down.

Common problems we fix in Greatness

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, and the spinning blades fling it onto the walls of the housing.

Look out for these warning signs:

  • Grease stains around the discharge
  • Grease around the motor and its mounts
  • A fan coated in grease inside its housing
  • Less air being pulled from the kitchen

For schools such as St John's Church of England Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Questions to ask before you book

What staff can safely do

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.

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, alongside our reports.

Extract fan cleaning around Greatness

The FSA’s food hygiene register includes about 11 bars, pubs and nightclubs and about 3 hotels, B&Bs and guest houses across Greatness and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Greatness is covered by Kent Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Food hygiene inspections in Greatness 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.

A hall kitchen that only cooks for events, whether near St John the Baptist or elsewhere in Greatness, still needs its extract cleaned, just less often. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Greatness is Sevenoaks Hospital, about within half a mile south-west.

Greatness is about 1 mile north-east of Sevenoaks, in Kent.

Greatness: your questions answered

Who inspects food businesses in Greatness?

That is Sevenoaks council, whose environmental health officers carry out food hygiene inspections in Greatness. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Do you cover smaller places like Greatness?

Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.

Are you accredited?

We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Can you come out in an emergency?

Yes. Our emergency line runs 24/7, for problems that cannot wait. Call us any time and explain what’s happened.

What is TR19?

TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

How do you protect the area?

By covering it before any work starts. We keep the work contained and clean down when we finish.

Which kinds of sites do you work on?

Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.

Can one contract cover all our sites?

Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.

Fixed quotes for extract fan cleaning in Greatness

The survey tells us what the work involves. The main factors are:

  • The size of the system
  • Whether it’s a one-off visit or part of a schedule
  • The number of sites or systems
  • Whether we need access equipment or extra panels

When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.

Asking for a quote

We can often survey from photos. The most useful are:

  • Any access panels or hatches you can see
  • Problems your staff have spotted
  • Where the site is and what kind of site it is
  • Any previous report or certificate

Quotes are quick. Send a few details and pictures, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

The process

There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, which takes an hour or two for most single fans. Everything the job in Greatness needs is worked out beforehand, from the survey.

  1. First we locate the fan and agree how it’s safely isolated.
  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. It’s closed up, run and checked, and pictures go into your report.

Getting ready for the visit

  • Move anything stored near the system
  • Let us know about parking and loading
  • Mention any locked doors, roof access or ceiling voids
