Canopy cleaning for sites in Blackfen

Canopy cleaning for kitchens and businesses in Blackfen

Every canopy we clean in Blackfen gets the same treatment: filters out, plenum scraped and degreased, then the canopy cleaned inside and out. You get pictures of the canopy before and after. If you are dealing with a filter housing caked in grease and grease dripping from the canopy edge, we can put it right, from wall canopies, canopy light fittings and baffle filters onwards.

Kitchens in Blackfen, 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.

The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Keeping the system healthy

Once we’ve finished, these simple steps help:

  • Empty the grease troughs before they fill
  • Check filters are not leaving gaps
  • Wipe the canopy down at close every day
  • Use non-abrasive cloths on the hood

Keep the photo report with your maintenance log, so it’s ready when an EHO, insurer or fire officer asks. Before and after pictures speak for themselves.

Empty the grease troughs and cups before they fill. Most canopy drips start with a full trough, so make emptying them part of the closing routine.

What we do, step by step

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. On site, the work takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. Security desks and permits-to-work are routine in London, so let us know what your building in Blackfen needs from us.

  1. The canopy is checked from photos or on a visit.
  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. Inside and out, the hood and its troughs are cleaned.
  5. Filters are refitted, the area cleaned down and the photo report put together.

How to prepare

  • Mention any sign-in, permit or induction we need
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Let us know when the site is closed or quiet

Common problems we fix in Blackfen

Most canopies have troughs or channels that catch running grease. Left to fill up, they spill over, and grease ends up dripping from the canopy edge.

Most sites get in touch when they notice one of these:

  • Canopy gutters full of old fat
  • Wet, greasy drips from the hood
  • Grease filters blocking between washes
  • Poor capture at the hood

For schools such as Our Lady of the Rosary Catholic Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

What your quote should include

  • When they can work, and whether that’s outside your opening hours
  • Proof of insurance
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • Whether inaccessible sections are listed on the report

Questions to ask before booking

For landlords and multi-site operators

Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.

FAQs for Blackfen

Can a school canteen extract in Blackfen be done out of term time?

Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 36 schools, colleges and universities with registered kitchens within about a mile and a half of Blackfen. Just phone us on 0345 646 2711 or send us an email with your term dates and we will plan around them.

Who enforces fire safety at workplaces in Blackfen?

That’s London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

What kinds of canopies do you clean?

Most commercial kitchen canopies, from one small hood to a long run of canopies. We work out the approach when we survey, from photos or a visit.

Who has the legal duty for fire safety?

That depends on who controls the premises. The Fire Safety Order 2005 puts the duty on the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.

Do you work in Blackfen?

Yes. We work in Blackfen and the rest of Greater London, as part of our work across South East England and London. To book, call 0345 646 2711 or use the quote form.

Will I get a report after the canopy clean?

A photo report shows the canopy and plenum before and after. If the canopy is cleaned as part of a full TR19 clean, a TR19 certificate is issued too.

How much of the canopy do you clean?

We clean the canopy inside and out, along with its seams and grease channels. The plenum and filter housing behind the filters are cleaned too.

What does canopy cleaning cost?

The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, normally ready within one working day.

What the work involves, part by part

Island canopies

Island canopies often have filters on two sides. We work round the canopy, cleaning each filter bank and plenum.

Pub and hotel kitchens

Pub and hotel kitchens can cook from breakfast to late evening. Long hours mean the canopy collects grease fast, so it may need cleaning between full TR19 cleans.

What staff can safely do

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.

Kitchen extracts in Blackfen

There are about 144 cafés, restaurants and staff canteens and about 90 takeaways and sandwich shops within roughly a mile and a half of the centre of Blackfen, according to the Food Standards Agency’s register. Wherever there’s a canopy over the cooking, its hood and plenum collect grease with every service. London Fire Brigade covers Blackfen. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Environmental health officers from Greenwich council inspect food businesses in Blackfen. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.

If you run a café or takeaway near Falconwood station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Where a hall near Church of the Good Shepherd, or anywhere in Blackfen, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

How we price canopy cleaning

We do not publish a price list, because no two systems are the same. What we look at:

  • Whether it’s a one-off visit or part of a schedule
  • Access, including roofs, risers and ceiling voids
  • Whether several sites go on one quote
  • The scale of the work

What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

What we need to know

There’s no need for technical detail. It helps if you can send:

  • Your last certificate, test record or report
  • The site address and the type of premises
  • The times we could work without disrupting the site
  • Any access panels or hatches you can see

Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before we start.
