Digswell canopy cleaning
For canopy cleaning in Digswell, one call is all it takes: survey, fixed quote, work and sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Overflowing grease troughs and gutters
- A plenum thick with grease behind the filters
- A sticky, discoloured canopy
Leave it or put it right?
When grease clogs the filters and plenum, the canopy cannot draw air as it should. The kitchen gets hotter and smokier, and the fan works harder for less. A clean canopy and plenum let the extract do its job. It’s better to plan the work at a site near Digswell than wait for a failure.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.

About our canopy cleaning in Digswell
We clean canopies in Digswell when the kitchen isn’t cooking: evenings, overnight, early mornings or weekends. The equipment underneath is switched off, left to cool and sheeted, and the kitchen is left ready for the next service. If you’re dealing with poor capture at the hood and heavy deposits behind the grease filters, we can help, from grease gutters, wall canopies and plenum chambers onwards.
Size doesn’t change the work: a kitchen in a place like Digswell gets the whole system cleaned, canopy to discharge. The visit is booked around your opening hours, and the journey is planned ahead.
A written report with photos follows every visit, 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.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Tell us when the canopy starts to drip
- Check filters aren’t leaving gaps
- Wash or exchange the filters on a regular cycle
- Check and empty canopy gutters regularly
File the report alongside your fire risk assessment where an inspector can see it. Photos of a clean canopy and plenum make the record easy to follow.
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.
What staff can safely do
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
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.
Honest limits
We will not sell you work that does not address the problem, so these are the things it won’t cover:
- Electrical faults in the canopy
- A fan that can’t pull enough air because it’s worn out
- A canopy undersized for the equipment
If you’re not sure, just give us a ring on 0345 646 2711 or email us and we will give you a straight answer.

FAQs for Digswell
Who carries out food hygiene inspections in Digswell?
That is Welwyn Hatfield council, whose environmental health officers carry out food hygiene inspections in Digswell. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Who is the fire and rescue service for Digswell?
Fire safety enforcement in Digswell is handled by Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Can I just have the canopy cleaned instead of the whole system?
You can have the canopy cleaned on its own, but it will not cover the ductwork or fan. For TR19, the whole system needs cleaning, at intervals set by BESA guidance.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What we do, step by step
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a few hours, depending on the size of the canopy and how much grease has built up, and we clear up before we go. Around Digswell, access is typically simpler than in a town centre, though gates and roof access are worth mentioning.
- We start by checking the canopy and what’s behind its filters.
- We protect everything below once it has cooled.
- Heavy deposits come off by hand, then the surfaces are degreased.
- Plenum, housing, troughs and canopy are all cleaned and checked.
- You get photos of the result and a recommended date for the next clean.
Before we arrive
- Clear loose items from the work area
- Let us know about permits to work or site inductions
- Arrange a key holder or contact on site
Getting a quote
Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Advice
How the job changes from site to site
Grease troughs and gutters
Some troughs drain to a cup or drawer, we empty and clean that as well, and we’ll show staff where it is.
Plenums and filter housings
Behind neglected filters, the plenum can be heavily coated. Heavy deposits are scraped out by hand before degreasing.
Kitchen extracts in Digswell
According to Food Standards Agency records, there are about 16 pubs and bars in Digswell and the streets around it, up to about 1.5 miles out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Digswell is covered by 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. It’s Welwyn Hatfield council that sends environmental health officers to food businesses in Digswell. 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 cook for passing trade around Welwyn North station, the extract can be cleaned between your last and first customer. Healthcare kitchens, like those at hospitals such as Queen Elizabeth II Hospital (about 2.5 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.

Common problems we fix in Digswell
Grease that runs down the inside of a canopy gathers in its gutters and troughs. If they’re not emptied, they fill and overflow, so fat ends up running down the front of the hood.
Any of these means the system needs a check-up:
- A greasy hood noticed by an inspector
- A filter housing caked in grease
- Wet, greasy drips from the hood
- Filters that clog soon after cleaning
Bursars and site managers at schools such as Harwood Hill Junior Mixed Infant and Nursery School tend to book extract cleaning for when the kitchen is empty.
