Canopy cleaning in How Wood, done properly
A greasy canopy tells an inspector a lot before they’ve opened anything. What is not seen, behind the filters, tends to be worse. We clean both, so the canopy is clean where it shows and where it doesn’t. We’re often asked to deal with smoke hanging around the canopy during service and wet, greasy drips from the hood, across island canopies, plenum chambers and canopy light fittings.
In a smaller place like How Wood, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Wash or exchange the filters on a regular cycle
- Report new drips or smells from the canopy
- Do not scrape the canopy with metal tools
- Make sure filters sit tight in the housing
A before and after photo report follows the clean. The report lists what was cleaned and any part we couldn’t get to, so the record is honest and complete.
Keep the fan running throughout service and for a short while after. Air that keeps moving carries less grease onto the canopy.
Common questions in How Wood
Do you work at weekends in How Wood?
Yes, nights and weekends are routine for us. The work in How Wood can fit around your hours. Tell us your opening hours when you ask for a quote.
Which fire and rescue service is responsible for How Wood?
Fire safety enforcement in How Wood is handled by Hertfordshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Why does grease run off the canopy edge?
Full gutters and a heavily coated plenum are the common causes. With nowhere to collect, the grease overflows, and condensation can carry it too. A canopy clean sorts it out.
How much notice do you need?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Do we need to close while you work?
Not typically. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
Do you provide pictures of the cleaned canopy?
You get a photo report with before and after pictures. If the canopy is cleaned as part of a full TR19 clean, a TR19 certificate is issued too.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.

Leave it or put it right?
When grease clogs the filters and plenum, the canopy cannot draw air as it should. Smoke and heat hang around the cooking line, and the fan works harder for less. A clean canopy and plenum let the extract do its job. Around How Wood, a kitchen or building out of action is missed right away.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

What happens on the day
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes an hour or two for one small canopy, longer where there are several. We plan the journey to How Wood and bring what the job is likely to need.
- We start by checking the canopy and what’s behind its filters.
- Equipment is turned off and cooled, and the area under the canopy is protected.
- Thick grease is scraped away before the canopy is degreased.
- Plenum, housing, troughs and canopy are all cleaned and checked.
- The canopy is signed off with before and after photos and a next clean date.
How to prepare
- Clear loose items from the work area
- Name a contact who can let us in at the agreed time
- Tell us the best time to work, such as after service or at a weekend

Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

What the work involves, 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.
Grease troughs and gutters
Drips from the canopy edge often start in a full gutter. We clean it out so the grease has somewhere to go.
Landlords, agents and facilities managers
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.
Facilities teams in offices, schools and healthcare sites book us too in How Wood and across Hertfordshire. Work can be phased by floor, building or site around the people who use them.
In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Day-to-day cleaning is something your team can do: 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.
Do you need canopy cleaning in How Wood?
Filters that are missing, damaged or badly seated leave gaps. More grease reaches the plenum and housing than they’re designed to take, which shows up as heavy deposits when the filters come out.
Most sites get in touch when they notice something like this:
- Grease channels that no longer drain
- A sticky, discoloured canopy
- Grease dripping from the canopy edge
- An EHO comment about the canopy
School kitchens, at schools like How Wood Primary and Nursery School for example, are usually cleaned in the holidays so no lunches are lost.

Kitchen extracts in How Wood
The FSA’s food hygiene register shows about 11 cafés, restaurants and staff canteens and about 13 takeaways in How Wood and the streets around it, up to about 1.5 miles out. Wherever there’s a canopy over the cooking, its hood and plenum collect grease with every service. How Wood sits within the area of Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. In How Wood, food businesses are inspected by environmental health officers from St Albans City council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
If you cook for passing trade around How Wood station, the extract can be cleaned between your last and first customer. If you run catering at a healthcare site, such as a hospital like Napsbury Hospital about 1.8 miles east, the extract may need cleaning more often than a part-time kitchen.
