When to call us in Harlesden

Filters that are missing, damaged or badly seated leave gaps. The plenum and housing behind them then take far more grease than they should, which shows up as heavy deposits when the filters come out.

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

  • A hood coated in old grease
  • Fat running down the front of the hood
  • Smoke hanging around the canopy during service
  • Filters that clog soon after cleaning

Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Harlesden is Central Middlesex Hospital, about 1 mile west.

About our canopy cleaning in Harlesden

For canopies and hoods in Harlesden, the work follows the same careful routine: we remove the filters, clean the plenum and housing, then degrease the canopy shell. You get photos of the canopy before and after. We are often asked to deal with grease dripping from the canopy edge and condensation and grease dripping together, on baffle filters, wall canopies and island canopies.

Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In Harlesden, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.

Good records are part of the job. Each visit is written up with photos, 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.

How it works

Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a few hours for most canopies. A name and number for whoever controls access to the building in Harlesden saves time on the night.

  1. We look at the canopy, filters and troughs first.
  2. Once the kitchen has closed, the cooking line is cooled and sheeted.
  3. With the filters removed, the plenum and filter channels are cleaned.
  4. The canopy shell, seams, troughs and gutters are degreased inside and out.
  5. We put the filters back, tidy up and photograph the finished canopy.

Before we arrive

  • Name a contact who can let us in at the agreed time
  • Allow time for equipment near the work to be turned off and cool down
  • Dig out any earlier paperwork for the system

Advice

Between visits

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

  • Check and empty canopy gutters regularly
  • Report new drips or smells from the canopy
  • Keep every filter in place while cooking
  • Avoid harsh scourers that scratch the canopy

Where the canopy is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. Where only the canopy is done, the report says so clearly.

Tell us if the canopy starts dripping or the filters clog sooner than usual. It can mean the cooking has changed or the interval is too long, which a grease thickness test can confirm.

Staff cleaning versus specialist work

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.

Kitchen extracts in Harlesden

The FSA’s food hygiene register shows about 269 restaurants, cafés and works canteens and about 168 sandwich bars and takeaways within about 1.5 miles of central Harlesden. Every kitchen among them that cooks under a canopy has a hood, plenum and filters collecting grease. Most London extract cleaning happens at night, after the last service. Environmental health officers from Brent council inspect food businesses in Harlesden. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.

School kitchens, at schools like John Keble CofE Primary School for example, are usually cleaned in the holidays so no lunches are lost. Commuter trade near Willesden Junction station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

Different parts, different methods

Plenums and filter housings

Behind the grease filters is the plenum. Grease that slips past the filters settles there, so it’s scraped and degreased on every canopy clean.

Wall canopies

A wall-mounted canopy runs along the back of the range. The joint between canopy and wall is a common grease trap, and we clean that join along with the inside of the hood.

Harlesden: your questions answered

Can you work in Harlesden outside opening hours?

Yes, we can come after you close and finish before you open. Your customers, staff or residents in Harlesden needn’t be disturbed. Your opening times are the first thing we ask for.

Which environmental health team covers Harlesden?

In Harlesden, it’s Brent council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Do you offer emergency callouts?

Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.

Do you clean inside the canopy as well as outside?

We clean the canopy inside and out, including the seams, troughs and gutters. The plenum and filter housing behind the filters are cleaned too.

Is there a survey before the work?

Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.

What does TR19 mean?

TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

Why is my canopy dripping grease?

Grease that builds up inside the canopy has to go somewhere. Once the troughs and plenum are full, it runs down and drips, often mixed with condensation. A thorough clean stops it.

Which kinds of sites do you work on?

Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.

How we price canopy cleaning

We do not publish a price list, because sites vary so much. The quote depends on:

  • What state the system is in
  • Where the site is and how we reach it
  • Any permits to work or inductions
  • One-off work versus a regular cycle

The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and the price is agreed before we start.

Asking for a quote

When you contact us, these details help:

  • The site address and the type of premises
  • When the site is open and when it’s quiet
  • A few general shots of the system
  • Your last certificate, test record or report

There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, phone us on 0345 646 2711, or send details by email.

Managing agents and facilities teams in Harlesden

Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.

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