Canopy Cleaning in Patchetts Green
Professional canopy cleaning in and around Patchetts Green, timed so the site keeps working and signed off in writing with photos.
- Grease dripping from the canopy edge
- Grease channels that no longer drain
- A sticky, discoloured canopy
What happens if it’s left?
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. Cleaning it removes that fuel. Out of sight is the usual reason a rural system goes too long without attention.
The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so there are no surprises.

How we handle canopy cleaning in Patchetts Green
Canopy cleaning is part of every full TR19® Grease clean, but some sites need the canopy done between full cleans. Where that’s the case, we will be clear that the ducts and fan are not included, so your records stay accurate. The work covers plenum chambers, grease gutters and canopy light fittings, and common reasons people get in touch are filters that clog soon after cleaning and an EHO comment about the canopy.
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.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Patchetts Green: your questions answered
Which council inspects kitchens in Patchetts Green?
That’s Hertsmere council, whose environmental health officers carry out food hygiene inspections in Patchetts Green. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Will you come out to Patchetts Green?
Yes, we work in villages as well as towns, and Patchetts Green is covered. Let us know about access, parking and anything unusual about getting there when you book.
What paperwork do I get after a canopy clean?
Every clean comes with a photo report, listing what was cleaned. A full TR19 clean adds a certificate from the BESCA Vent Hygiene Elite portal.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Do you look at the system first?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
Does a canopy clean meet TR19?
You can have the canopy cleaned on its own, but it won’t cover the ductwork or fan. TR19 Grease covers everything the grease travels through, at intervals set by BESA guidance.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we will quote them together.
What happens if you can’t reach some of it?
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.
Between visits
After the visit, a few habits help the work last:
- Refit filters the right way round and fully seated
- Clean the baffle filters often
- Avoid harsh scourers that scratch the canopy
- Keep the fan on through service
We point out anything we noticed while the canopy was apart: bent or poorly fitting filters, a light cover that’s cracked, or troughs that fill too quickly. It’s a short list of what to watch, not a sales pitch.
Tell us if the canopy starts dripping or the filters clog sooner than usual. It can mean the cooking has changed or the interval is too long, which a grease thickness test can confirm.
How it works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes an hour or two for one small canopy, longer where there are several. Photos of the system and how to reach it help us plan a visit to Patchetts Green.
- The canopy is checked from photos or on a visit.
- Out of hours, the range is switched off, cooled and covered.
- We lift out the filters and scrape the plenum and housing.
- The canopy shell, seams, troughs and gutters are degreased inside and out.
- We put the filters back, tidy up and photograph the finished canopy.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Find the previous report, if there is one
- Let us know about permits to work or site inductions
Ask for a quote
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Advice
How we price canopy cleaning
Before we fix a price, we need to know a few things. We look at:
- Whether several sites go on one quote
- Site requirements such as sign-in and permits
- Working hours and out-of-hours timing
- The condition of the system
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before we start.
Helping us quote
To help us quote quickly, please include:
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
- Your last certificate, test record or report
To help us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Once you have those, give us a ring on 0345 646 2711, or send details by email.
Part by part
Wall canopies
Wall canopies sit against a wall over a cooking line. Grease often collects where the canopy meets the wall, and we clean that join along with the inside of the hood.
Island canopies
An island canopy is open on all sides, so every face can collect grease. Each face is cleaned inside and out.
Canopy cleaning around Patchetts Green
The Food Standards Agency lists about 10 pubs and bars as registered food businesses within about 1.5 miles of central Patchetts Green. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Patchetts Green, food businesses are inspected by environmental health officers from Hertsmere council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand. Hertfordshire Fire and Rescue Service covers Patchetts Green. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you look after a school kitchen, at a school such as Queens' School or anywhere near Patchetts Green, the holidays are the usual time for a TR19® clean. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Watford General Hospital is the nearest hospital to Patchetts Green, about 2.5 miles south-west. Where a hall near Church of St John the Baptist, or anywhere in Patchetts Green, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

When it’s something else
We will not sell you work that does not address the problem, so these are the things it will not cover:
- A fan that cannot pull enough air because it’s worn out
- A hood that does not cover the cooking line
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
