Canopy cleaning in Cooper's Green

A greasy canopy tells an inspector a lot before they’ve opened anything. What isn’t seen, behind the filters, tends to be worse. Canopy cleaning deals with both, so the hood looks right and works properly. Typical jobs include an EHO comment about the canopy and a filter housing caked in grease, on grease gutters, baffle filters and canopy light fittings.

In a small place like Cooper's Green, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.

A written report with pictures follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

When to call us in Cooper's Green

Grease that runs down the inside of a canopy gathers in its gutters and troughs. Left to fill up, they spill over, and grease ends up dripping from the canopy edge.

Clients normally contact us when they notice one of these:

  • A sticky, discoloured canopy
  • Poor capture at the hood
  • Grease dripping from the canopy edge
  • A filter housing caked in grease

Historic houses near Cooper's Green, such as Hatfield House about 2.7 miles east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Questions from Cooper's Green

Who would carry out a food hygiene inspection at a kitchen in Cooper's Green?

The local authority for Cooper's Green is Welwyn Hatfield council, and its environmental health team does the inspecting. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

Do you work overnight in Cooper's Green?

Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Cooper's Green needn’t be disturbed. When you ring 0345 646 2711 or drop us a line, mention when the site is quiet.

What happens if you cannot reach some of it?

They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.

How long is a canopy clean?

Size and build-up decide it. Typically it takes a few hours, depending on the size of the canopy and how much grease has built up.

Do you cover Cooper's Green?

Yes. Cooper's Green is part of the area we cover, as part of our area across London and the South East.

Do you provide pictures of the cleaned canopy?

Every clean comes with a photo report, listing what was cleaned. Where the whole system is cleaned, you also get a TR19 certificate through the BESCA Vent Hygiene Elite portal.

Do you clean canopies in all kinds of kitchens?

Single hoods, long wall canopies and island canopies alike. We work out the approach when we survey, from pictures or a visit.

Which kinds of sites do you work on?

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

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, depending on the size of the canopy and how much grease has built up. Pictures of the system and its access let us plan the work in Cooper's Green before we set off.

  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. Inside and out, the hood and its troughs are cleaned.
  5. We put the filters back, tidy up and photograph the finished canopy.

How to prepare

  • Name a contact who can let us in at the agreed time
  • Let us know when the site is closed or quiet
  • Tell us where we can park and unload

What affects the cost of canopy cleaning

There’s no set price list, because sites vary so much. The quote depends on:

  • Access, including roofs, risers and ceiling voids
  • Whether it’s a one-off visit or part of a schedule

Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.

  • Your opening hours and when the area is out of use
  • Where the site is and what kind of site it is

  • The paperwork from the last visit, if you have it

Aftercare tips

So the system stays in good health:

  • Keep filters on a set cleaning routine
  • Make sure filters sit tight in the housing
  • Do not scrape the canopy with metal tools
  • Leave the extract running until cooking stops

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.

Clean filters are the canopy’s first defence. Keep them on a regular cleaning or exchange cycle, and make sure they’re all in place before cooking. Less grease gets into the plenum as a result.

What canopy cleaning can’t fix

In fairness, there are a few things this work won’t fix:

  • Filters that no longer seal in the housing
  • A canopy too small for the cooking under it (that’s a design question)
  • Poor airflow from a fan that needs repair

If in doubt, ring 0345 646 2711 or send us an email and we’ll say what we think.

What we work on in Cooper's Green

For landlords and multi-site operators

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.

We also work for facilities teams across offices, schools and healthcare in Cooper's Green and across Hertfordshire. Larger estates can be phased building by building around the people who use them.

Part by part

Plenums and filter housings

Behind the grease filters is the plenum. Grease that slips past the filters settles there, and it’s cleaned every time we clean the canopy.

Wall canopies

Long wall canopies often have several filter banks. We work along the canopy section by section, with pictures for each.
