Canopy cleaning in Harmer Green, done properly
A kitchen team can wipe the outside of a canopy, but the seams, gutters and inner skin need more. Thick deposits are scraped off by hand, then the surfaces degreased to suit what’s there, using hot water or steam where it helps. The work covers canopy light fittings, island canopies and grease gutters, and common reasons people get in touch are a hood coated in old grease and a plenum thick with grease behind the filters.
In a village or hamlet like Harmer Green, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Canopy cleaning in Harmer Green: the local picture
Food Standards Agency records include about 15 bars, pubs and nightclubs within roughly a mile and a half of the centre of Harmer Green. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Harmer Green is covered by Hertfordshire Fire and Rescue Service. 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. It’s East Hertfordshire council that sends environmental health officers to food businesses in Harmer Green. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
For kitchens close to Welwyn North station, where the day often starts early and ends late, the extract can be cleaned overnight. A hospital like Queen Elizabeth II Hospital, about 3.4 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Part by part
School and staff canteen kitchens
School and canteen kitchens often cook to set hours, so the canopy can be cleaned when the kitchen is closed. We often clean them in holidays or at weekends.
Pub and hotel kitchens
In pubs and hotels, the kitchen may be busy for much of the day. Long hours mean the canopy collects grease fast, so it may need cleaning between full TR19 cleans.
What canopy cleaning can’t fix
An honest diagnosis matters more to us than a booking, so here’s what canopy cleaning will not do:
- Weak extraction caused by a failing fan motor
- Electrical faults in the canopy
- A hood that doesn’t cover the cooking line
If in doubt, call us on 0345 646 2711 or use the quote form and we will say what we think before booking.
Where we work
- Grease gutters
- Plenum chambers

Common questions in Harmer Green
Who would carry out a food hygiene inspection at a kitchen in Harmer Green?
In Harmer Green, it’s East Hertfordshire council that carries out food hygiene inspections. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Do you work at weekends in Harmer Green?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Just phone us on 0345 646 2711, or send details by email with your opening times and we will plan around them.
Does a canopy clean meet TR19?
TR19® Grease is about the whole extract, from canopy to discharge. Cleaning the canopy alone leaves the ducts, risers and fan untouched, and the report will say what was covered.
Will I get a report after the canopy clean?
You get a photo report with before and after photos. If the canopy is cleaned as part of a full TR19 clean, a TR19 certificate is issued too.
Are you fully insured?
Yes. We carry full insurance, and we have been trading since 2009.
Do you clean the grease filters as part of a canopy clean?
We remove the filters to reach the plenum, then clean and refit them. Any that are damaged are noted on the report.
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.
Who is the responsible person?
It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Aftercare tips
Think of this as the after-treatment advice, in brief:
- Make sure filters sit tight in the housing
- Empty the grease troughs before they fill
- Wipe the canopy down at close every day
- Leave the extract running until cooking stops
We clear away the sheeting, waste grease and water before we leave. Filters are back in place and seated properly, and the kitchen is ready to cook.
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.
Why act early in Harmer Green
Fresh grease comes off far more easily than old. Over months, the heat hardens it into a stubborn coating, so the longer it’s left, the longer the clean takes. Our emergency line runs 24/7, but a planned visit to Harmer Green is calmer for everyone.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
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. Leave those to us.
Signs you need canopy cleaning in Harmer Green
Air straight off the range hits the canopy first. Grease from the vapour lands on the canopy’s inner surfaces, its joints and its filters before what gets through reaches the plenum.
Keep an eye out for any of the following:
- A canopy that no longer draws the smoke away
- Canopy gutters full of old fat
- Fat running down the front of the hood
- A canopy flagged at an environmental health inspection
Term dates shape school work: for a school like Oaklands Primary School, an extract clean fits neatly into a half-term or summer break.
