Canopy cleaning in Clerkenwell

What staff can safely do

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Canopy cleaning in Clerkenwell, done properly

Every TR19® Grease clean includes the canopy, but some sites need the canopy done between full cleans. Where that’s the case, we’ll be clear that the ducts and fan aren’t included, so your records stay accurate. The work covers baffle filters, island canopies and wall canopies, and common reasons people get in touch are filters that clog soon after cleaning and a hood coated in old grease.

Kitchens in Clerkenwell, 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, so a regular TR19® clean protects everyone in it.

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

What affects the quote in Clerkenwell

Sites vary more than people expect. What affects the quote:

  • Site requirements such as sign-in and permits
  • The condition of the system
  • The times the site is available
  • One-off work versus a regular cycle

When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before any work starts.

Asking for a quote

Before you ask for a quote, gather:

  • Detail shots of panels, filters and grilles
  • The postcode and the type of business
  • How we’d reach plant on a roof or in a plant room
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

When something else is needed

A few issues sit outside what this work can do:

  • A canopy too small for the cooking under it (that’s a design question)
  • A dirty extract fan further along the system
  • A light fitting that does not work

If in doubt, call 0345 646 2711 or send us an email and we will say what we think.

What the work covers

  • Baffle filters
  • Canopy light fittings
  • Grease gutters
  • Island canopies
  • Wall canopies
  • Plenum chambers

For landlords and multi-site operators

If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.

Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.

FAQs for Clerkenwell

Do you do school kitchen extract cleaning in Clerkenwell in the summer holidays?

Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 69 schools and colleges with food registrations within roughly a mile and a half of Clerkenwell. Tell us your holiday dates and we will book the visit for when the site is empty.

Who enforces fire safety at workplaces in Clerkenwell?

London Fire Brigade is the fire and rescue service for Clerkenwell. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.

Which sectors do you work in?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.

How long is a canopy clean?

That depends on the size of the canopy and how much grease is on it. As a guide, it takes part of a shift for most kitchens, more where there are several canopies or heavy deposits.

What is TR19?

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

What accreditations do you have?

Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.

Do you offer maintenance contracts?

Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.

Will we have to shut during the visit?

Not usually. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.

Clerkenwell kitchens: local notes

The Food Standards Agency lists about 519 pubs and bars and about 165 hotels and guest houses as registered food businesses in Clerkenwell and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. London Fire Brigade covers Clerkenwell. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Kitchens in Clerkenwell get their food hygiene inspections from Islington council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

Where a hall near St James's Church, or anywhere in Clerkenwell, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you look after a school kitchen, at a school such as St Peter and St Paul RC Primary School or anywhere near Clerkenwell, the holidays are the usual time for a TR19® clean.

Leave it or put it right?

Leaving the canopy until the next full clean can mean months of build-up. In a busy kitchen, the canopy and plenum can need attention between TR19 cleans, and readings or a look behind the filters will show it. For a site in Clerkenwell, fitting the work in overnight now is far easier than closing at short notice later.

Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

The process

On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes an hour or two for one small canopy, longer where there are several. Security desks and permits-to-work are routine in London, so let us know what your building in Clerkenwell needs from us.

  1. We look at the canopy, filters and troughs first.
  2. Out of hours, the range is switched off, cooled and covered.
  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. Filters are refitted, the area cleaned down and the photo report put together.

Preparing for the visit

  • Make sure someone can let us in and lock up afterwards
  • Clear loose items from the work area
  • Allow time for equipment near the work to be turned off and cool down

Advice

Signs you need canopy cleaning in Clerkenwell

Moisture in the air mixes with the grease on the canopy. Water vapour condenses on the cooler canopy surfaces and drips, carrying grease with it. The result is sticky streaks and drips onto the range.

The symptoms we’re asked about most are:

  • A filter housing caked in grease
  • Grease filters blocking between washes
  • Grease channels that no longer drain
  • A canopy that no longer draws the smoke away

Commuter trade near Farringdon station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

What your quote should include

  • If the quote is a fixed price or an estimate
  • Which accreditations they hold, and whether you can check them
  • How areas they can’t reach will be recorded
  • Exactly which parts of the system are covered
