Extract fan cleaning near Harrow

Extract fan cleaning in Harrow, done properly

Grease on a fan isn’t spread evenly. Heavier deposits on some blades throw the impeller off balance, leading to vibration, noise and strain on the motor and bearings. A thorough clean removes the cause. The work covers discharge points, centrifugal fans and roof-mounted fans, and common reasons people get in touch are vibration from an unbalanced impeller and a fan that no longer moves enough air.

Kitchens in Harrow, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.

Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Staff cleaning versus specialist work

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.

Your questions about extract fan cleaning in Harrow

Can parking be tricky for a job in Harrow?

A loading bay, a visitor permit or off-street space near the site in Harrow makes the visit easier to plan. Working overnight, as we often do in London, typically makes it simpler.

Who inspects food businesses in Harrow?

Food hygiene inspections in Harrow are carried out by Harrow council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.

Do you have a 24/7 line?

Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.

Can the work be done while we’re closed?

Yes. Evenings, nights and weekends are normal working hours for us, so you don’t have to close during trading.

Can you set up regular visits?

Yes. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.

Can you fix a fan that’s worn out?

Fan repair and replacement is part of what we do. If we find wear or damage, we’ll explain it and send you a fixed quote.

Do you have insurance?

Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.

How long does extract fan cleaning take?

A single accessible fan doesn’t take long, while fans on high roofs or in tight voids take longer. It’s done while the kitchen is closed.

When something else is needed

Not every problem is solved by extract fan cleaning, and we will tell you before we start. It will not put right:

  • A fan that will not start
  • Wiring faults to the fan
  • A fan that’s too small for the system (a design question)

Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we will tell you honestly.

Parts of the system we cover

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

How the job changes from site to site

Roof-mounted fans

Roof fans also discharge grease onto the roof around them, so the outlet area is checked too. We note any grease around the fan.

Kitchens with long cooking hours

Kitchens that cook 12 to 16 hours a day put the most grease through their fans. BESA guidance sets at least 3-monthly cleaning for that level of use, fan included.

How we price extract fan cleaning

Some jobs are bigger than they look, and some smaller. The main factors:

  • A single visit or a regular plan
  • How big the system is
  • Access, including roofs, risers and ceiling voids
  • Where the site is and how we reach it

The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.

Asking for a quote

To help us quote quickly, send us:

  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • The site address and the type of premises
  • Close-ups of filters, grilles, hatches or access panels
  • Problems your staff have spotted

Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

The process

On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes a few hours where there are several fans or heavy deposits. A name and number for whoever controls access to the building in Harrow saves time on the night.

  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. We reassemble, run the fan and photograph the result.

Before we arrive

  • Have your last certificate or report to hand
  • Allow time for equipment near the work to be turned off and cool down
  • Mention any locked doors, roof access or ceiling voids

Harrow kitchens: local notes

The Food Standards Agency lists about 26 pubs and bars and about 3 hotels and B&Bs as registered food businesses within 1.5 miles or so of the middle of Harrow. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Harrow sits within the area of London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Kitchens in Harrow get their food hygiene inspections from Harrow council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.

Commuter trade near Harrow-on-the-Hill station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Volunteers running a hall kitchen near Church of St Peter, or anywhere in Harrow, may not know when the extract was last cleaned, and a grease test settles it.

Looking after it afterwards

A little care between visits keeps the system in better shape. We recommend:

  • Keep the grease filters clean and in place
  • Keep the fan on whenever the range is lit
  • Look for grease stains near the discharge
  • Leave a clear route to the fan

A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.

Keep the whole system on its cleaning cycle. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.

Do you need extract fan cleaning in Harrow?

Poor filters mean a greasier fan. Missing, damaged or badly fitted filters let grease travel the whole system, so the fan takes far more than it should.

If you notice any of these, it’s worth a diagnosis:

  • Grease escaping from the fan outlet
  • A motor area thick with grease
  • A smell of hot grease from the extract
  • Thick grease on the impeller and casing

Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Harrow is Clementine Churchill Hospital, about 1 mile south-east.

Before you book anyone

  • Whether the quote shows VAT
  • Whether the work can be done while the site is closed
  • What happens if part of the system can’t be accessed
  • Whether the whole system is included, or only the parts that are easy to reach
