Canopy cleaning in St Paul's Walden, done properly
We clean canopies in St Paul's Walden when the kitchen is not cooking: evenings, overnight, early mornings or weekends. The equipment underneath is switched off, left to cool and sheeted so the kitchen is ready when we go. We are often asked to deal with fat running down the front of the hood and condensation running down the canopy, on baffle filters, canopy light fittings and island canopies.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
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.

St Paul's Walden: your questions answered
Who carries out food hygiene inspections in St Paul's Walden?
That’s North Hertfordshire council, whose environmental health officers carry out food hygiene inspections in St Paul's Walden. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can you work in St Paul's Walden outside opening hours?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in St Paul's Walden needn’t be disturbed. Just ring 0345 646 2711, or email photos with your opening times and we will plan around them.
Is the inside of the hood cleaned?
All of it: the outer surfaces, the inner skin, the seams and the troughs. We also remove the filters and clean the plenum and housing behind them because that is often the dirtiest part.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Do you clean canopies in all kinds of kitchens?
Wall canopies, island canopies and single hoods over individual appliances. Each one is cleaned inside and out, with the plenum behind the filters.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Why is my canopy dripping grease?
Usually because the troughs or gutters are full, or the plenum is overloaded. Grease has nowhere else to go, so it runs down and drips, and condensation can carry it too. A canopy clean sorts it out.
How long does canopy cleaning take?
A single canopy with a light build-up is fairly quick, but large or heavily soiled canopies take longer. You’ll know before any work starts.
In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

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.

What the work covers

- Baffle filters
Part by part
Island canopies
Island canopies often have filters on two sides. We work round the canopy, cleaning each filter bank and plenum.
Wall canopies
A long wall canopy may hold several sections of filters. We work along the canopy section by section, with pictures for each.
Why act early in St Paul's Walden
A greasy canopy is fuel directly above the flame. A flare-up can catch it and be drawn into the plenum and duct, where a fire is much harder to stop. A clean canopy takes that fuel away. In a place like St Paul's Walden, ductwork and fans are easy to forget until something goes wrong.

What affects the cost of canopy cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Where the site is and how we reach it
- The condition of the system
- The size of the system
- One-off work versus a regular cycle
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

Before you ask for a quote, gather:
- Wide photos of the system and the area around it
- When the site is open and when it’s quiet
- Any access panels or hatches you can see
- Where the plant sits or the system leaves the building, such as a roof or outside wall

What happens on the day
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off.

Visits to a village like St Paul's Walden are booked in advance, at a time that suits whoever runs the site.
- We look at the canopy first, from photos or on a visit.
- The range is turned off and allowed to cool before we cover it.
- With the filters out, the plenum and housing are cleaned back.
- We degrease the canopy shell, its seams and the grease troughs.
- We refit the filters, clear up and photograph the finished canopy.

What else we do in St Paul's Walden
Common problems we fix in St Paul's Walden
Air straight off the range hits the canopy first. Fat in that air settles on the inside of the hood, in its seams and on the filters, and the plenum behind them collects the rest.
It’s time to book a visit if you see:
- A plenum thick with grease behind the filters
- An EHO comment about the canopy
- A hood coated in old grease
- Filters that clog soon after cleaning
If you run a church or community hall kitchen, near All Saints Church or elsewhere in St Paul's Walden, its extract still collects grease from every lunch and event.
What your quote should include
- What paperwork you get at the end
- When they can work, and whether that is outside your opening hours
- When the next visit should be, and why
- Whether a survey comes first
