In-house cleaning or a specialist?

Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Extract fan cleaning for kitchens and businesses in Northwick Park

In Northwick Park, as everywhere we work, the fan follows a set routine: isolated first, then opened, scraped and degreased. Your report shows the impeller as we found it and as we left it. The work covers discharge points, roof-mounted fans and fan housings, and common reasons people get in touch are a fan that has never been cleaned and hot, greasy smells near the fan.

London kitchens tend to trade late and open early, so extract cleaning in Northwick Park is typically done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.

For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What happens on the day

Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes a couple of hours per fan, depending on its size and the build-up, and we clear up before we go. Getting kit into a London building takes planning, so let us know where we can load and park in Northwick Park.

  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. The impeller and the housing around it are scraped clean.
  4. We degrease the fan and housing, taking care around the motor.
  5. We reassemble, run the fan and photograph the result.

Getting ready for the visit

  • Name a contact who can let us in at the agreed time
  • Make sure equipment near the work can be switched off and left to cool
  • Mention any sign-in, permit or induction we need

Advice

Questions from Northwick Park

Is parking a problem for work in Northwick Park?

Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.

Can the work in Northwick Park be done at night or at weekends?

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

How much notice do you need?

For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.

Is the fan isolated during cleaning?

With the fan isolated, the extract is not running. That is why fan cleans are done out of hours, and the kitchen is ready when we leave.

Will I get pictures of the cleaned fan?

You get a photo report with before and after pictures of the fan. If it’s part of a full TR19 clean, a TR19 certificate is issued too.

How long is a fan clean?

That depends on the fan’s size, its position and how much grease there is. As a guide, it takes a couple of hours per fan, depending on its size and the build-up.

Can you look after several sites?

Yes. Tell us the addresses and what each needs and we’ll quote them together.

Which sectors do you work in?

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

Part by part

Impellers and blades

While the impeller is clean, we can see its condition: chips, distortion or wear. We note any concerns.

Roof-mounted fans

Grease can escape from a roof fan onto the surrounding surface, so the outlet area is checked too. Heavy staining is noted on the report.

When it’s something else

Some problems need a different service or another trade:

  • A fan that is too small for the system (a design question)
  • A motor that has burnt out
  • Wiring faults to the fan

If in doubt, call us on 0345 646 2711 or use the quote form and we’ll say what we think before booking.

Parts of the system we cover

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

Grease, kitchens and Northwick Park

The Food Standards Agency lists about 28 pubs and bars and about 3 hotels, B&Bs and guest houses as registered food businesses across Northwick Park and its immediate surroundings (about a mile and a half). A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Northwick Park is covered by London Fire Brigade. 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. In Northwick Park, food businesses are inspected by environmental health officers from Harrow council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

A hall kitchen that only cooks for events, whether near Saint Cuthberts Church or elsewhere in Northwick Park, still needs its extract cleaned, just less often. A hospital like Northwick Park Hospital, about within half a mile north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you look after a school kitchen, at a school such as Harrow High School or anywhere near Northwick Park, the holidays are the usual time for a TR19® clean.

What happens if it’s left?

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. Choosing the date yourself beats having a fault choose it for you.

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

Fixed quotes for extract fan cleaning in Northwick Park

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • A single visit or a regular plan
  • The scale of the work
  • How easy every part is to reach
  • Working hours and out-of-hours timing

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, call 0345 646 2711 or email us for straight advice and a fixed quote.

Helping us quote

You do not need the technical terms. It helps if you can send:

  • Your last certificate, test record or report
  • Your opening hours and when the area is out of use
  • Detail shots of panels, filters and grilles
  • A few general shots of the system

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 work begins.

Between visits

After the visit, a few habits help the work last:

  • Report rattles or humming early
  • Keep access to the fan clear
  • Don’t turn the fan off mid-service
  • Check filters are seated before cooking

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.

A change in how the fan sounds is worth noting. Rattles, hums or shaking can be early signs of build-up or wear and early action can save a repair.
