Marshalswick canopy cleaning
Canopy cleaning for Marshalswick, with a survey first and a report with photos at the end. Ask us for a fixed quote.
- A canopy flagged at an environmental health inspection
- A filter housing caked in grease
- Filters that never seem to stay clean
What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Canopy cleaning in Marshalswick, done properly
Every TR19® Grease clean includes the canopy, but some sites need the canopy done between full cleans. In that case, the report makes clear what was and wasn’t cleaned, so your records stay accurate. If you’re dealing with fat running down the front of the hood and heavy deposits behind the grease filters, we can put it right.
For a smaller kitchen near Marshalswick, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

FAQs for Marshalswick
Can you work in Marshalswick outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just call 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Do you clean school canteen extracts around Marshalswick out of term?
Yes, holiday work suits schools best. Around Marshalswick, the Food Standards Agency lists about 18 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Who has the legal duty for fire safety?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Is TR19 cleaning required by law?
No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
What’s TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do you cover Marshalswick?
Yes. We cover Marshalswick and across Hertfordshire, within our South East and London area. For a fixed quote, give us a ring on 0345 646 2711, or send details by email.

What else we do in Marshalswick
What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes an hour or two for one small canopy, longer where there are several. Around Marshalswick, access is usually simpler than in a town centre, though gates and roof access are worth mentioning.
- We start by checking the canopy, filters and plenum.
- The range is turned off and allowed to cool before we cover it.
- Filters come out and the plenum behind them is scraped and degreased.
- The canopy is cleaned inside and out, including troughs and seams.
- Clean filters are refitted and before and after pictures go into your report.
How to prepare
- Find the previous report, if there is one
- Arrange a key holder or contact on site
- Let us know about parking and loading

Between visits
Good habits slow the build-up between visits. Our tips:
- Wipe the canopy down at close every day
- Keep every filter in place while cooking
- Empty the grease troughs before they fill
- Check filters aren’t leaving gaps
After the clean you get a photo report showing the canopy, plenum and housing before and after. It notes what was cleaned and anything we couldn’t reach, 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.
Part by part
Island canopies
With filters on more than one side, an island canopy has more plenum to clean. We work round the canopy, cleaning each filter bank and plenum.
Plenums and filter housings
A plenum that hasn’t been cleaned for a long time can hold a thick layer of grease. Heavy deposits are scraped out by hand before degreasing.
Common problems we fix in Marshalswick
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.
If you notice any of these, it’s worth a diagnosis:
- Drips from the canopy onto the range
- A sticky, discoloured canopy
- Smoke hanging around the canopy during service
- Wet, greasy drips from the hood
If you run catering at a historic house or estate in the area (Batchwood Hall is about 2 miles west), event kitchens in older buildings often have awkward duct runs that need planning.
What your quote should include
- Whether they’re fully insured
- What paperwork you get at the end
- When the next visit should be, and why
- Whether the quote shows VAT
What canopy cleaning can’t fix
Canopy cleaning cannot fix everything, and we will tell you before any work starts. It will not put right:
- Electrical faults in the canopy
- A fan that can’t pull enough air because it’s worn out
- A canopy too small for the cooking under it (that is a design question)
If you’re not sure, just phone us on 0345 646 2711 or send us an email and we’ll give you a straight answer.
What we work on in Marshalswick

What affects the cost of canopy cleaning
Every site gets its own quote. These are the things that affect it:
- Any permits to work or inductions
- The size of the system
- The number of sites or systems
- Whether we need access equipment or extra panels
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, ring 0345 646 2711 or email us for straight advice and a fixed quote.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- How we’d reach plant on a roof or in a plant room
- Any previous report or certificate
- Your opening hours and when the area is out of use
- Problems your staff have spotted
Getting a quote doesn’t take long. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Kitchen extracts in Marshalswick
The FSA’s food hygiene register shows about 83 restaurants, cafés and canteens and about 33 sandwich bars and takeaways in Marshalswick and the streets around it, up to about 1.5 miles out. Each canopy in those kitchens catches grease on the inside of the hood and behind the filters. Environmental health officers from St Albans City council inspect food businesses in Marshalswick. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after photos from each clean are a simple way to show the extract is in hand. Fire safety in Marshalswick falls to 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.
Bursars and site managers at schools such as St John Fisher Roman Catholic Primary School tend to book extract cleaning for when the kitchen is empty. Healthcare kitchens, like those at hospitals such as Hill End Hospital (about 1.1 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.
