What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- A fan that cannot pull enough air because it’s worn out
- Bent or broken filters
- A light fitting that doesn’t work
If in doubt, call 0345 646 2711 or drop us a line and we’ll say what we think before booking.

How we handle canopy cleaning in Chiswell Green
For canopies and hoods in Chiswell Green, the work follows the same careful routine: we remove the filters, clean the plenum and housing, then degrease the canopy shell. Before and after photos go into your report. The work covers grease gutters, canopy light fittings and wall canopies, and common reasons people get in touch are a plenum thick with grease behind the filters and a canopy flagged at an environmental health inspection.
In a smaller place like Chiswell Green, 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 report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.

Questions from Chiswell Green
Do you work at weekends in Chiswell Green?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just ring 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Is Chiswell Green within the area you cover?
Yes, Chiswell Green is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Does the law say we must follow TR19?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005, which applies in England and Wales.
What paperwork do I get after a canopy clean?
Before and after photos go into a report, listing what was cleaned. Where the whole system is cleaned, you also get a TR19 certificate through the BESCA Vent Hygiene Elite portal.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. Quotes typically come back within one working day, and emergencies are covered by our 24/7 line.
Do you clean canopies in all kinds of kitchens?
We clean canopies in commercial kitchens of every kind. The routine stays the same whatever the kitchen, with the equipment off and cool.
Can you come out in an emergency?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
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 grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Canopy cleaning around Chiswell Green
Food Standards Agency records list about 11 restaurants, cafés and canteens and about 13 sandwich bars and takeaways within about 1.5 miles of central Chiswell Green. Any of those kitchens with a canopy has a hood that needs cleaning inside and out. Fire safety in Chiswell Green falls to 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. Food hygiene inspections in Chiswell Green are the job of St Albans City council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you run a café or takeaway near Park Street station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. A hospital like Napsbury Hospital, about 2.1 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Bursars and site managers at schools such as Killigrew Primary and Nursery School tend to book extract cleaning for when the kitchen is empty.

Why it’s worth doing now in Chiswell Green
Baked-on grease gets harder to shift the longer it stays. Heat from the range bakes canopy grease into a hard, dark layer, so the longer it’s left, the longer the clean takes. A visit arranged in advance is far less disruptive than a callout on a busy day.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before we start.
What you get with us
- CHAS, SafeContractor and ISO 9001
- A fixed price before any work starts
- One contact for all your sites in London and the South East
- Work around your opening hours, with 24/7 emergency cover
Between visits
So the system stays in good health:
- Leave the extract running until cooking stops
- Check and empty canopy gutters regularly
- Refit filters the right way round and fully seated
- Keep every filter in place while cooking
File the report alongside your fire risk assessment, so it’s ready when an EHO, insurer or fire officer asks. Before and after pictures speak for themselves.
Run the extract for as long as anything is cooking. Turning the fan off early lets vapour settle on the hood.
How the job changes from site to site
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, and canopy cleans between full cleans can help.
Wall canopies
The back of a wall canopy is hard to reach and easy to miss. With the filters out we can get to it and degrease it properly.
What we do, step by step
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, tidy up and leave you the report. The visit itself takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. For a site near Chiswell Green, the work is booked around your opening hours, evenings and weekends included.
- First the canopy is surveyed, by photos or in person.
- Equipment below is switched off and left to cool, then sheeted.
- We remove the grease filters and clean the plenum and filter housing.
- Inside and out, the canopy and its grease channels are degreased.
- We refit the filters, clear up and photograph the finished canopy.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know when the site is closed or quiet

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.
