Canopy cleaning for kitchens and businesses in Letchworth Garden City
Has the canopy started to drip or look neglected?

Many kitchens in a town like Letchworth Garden City were fitted into buildings built for something else, which can mean awkward duct routes, long flat runs and not enough access panels. Sections we can’t reach are listed on the report, and access panels can be added.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Letchworth Garden City questions
Who carries out food hygiene inspections in Letchworth Garden City?
In Letchworth Garden City, it’s North Hertfordshire council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Which fire service covers Letchworth Garden City?
Fire safety enforcement in Letchworth Garden City is handled by Hertfordshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What does canopy cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
Who is responsible for fire safety on the premises?
The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.

Part by part
Island canopies
Island canopies often have filters on two sides. We work round the canopy, cleaning each filter bank and plenum.
Plenums and filter housings
The rails and channels that hold the filters collect grease. We clean them so the filters sit tight and leave no gaps.
What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes a few hours, depending on the size of the canopy and how much grease has built up. We arrive in Letchworth Garden City once you’ve closed and leave the site ready for the morning.
- We look at the canopy first, from pictures or on a visit.
- Cooking equipment is left to cool and the area under the canopy protected.
- 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
- Mention any locked doors, roof access or ceiling voids
- Tell us the best time to work, such as after service or at a weekend
- Mention any sign-in, permit or induction we need
How to get a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Related advice
Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Keep every filter in place while cooking
- Run the extract the whole time you are cooking
- Use non-abrasive cloths on the hood
- Keep filters on a set cleaning routine
A before and after photo report follows the clean. The report lists what was cleaned and any part we couldn’t get to, so the record is honest and complete.
A daily wipe of the hood keeps fresh grease from baking on. It does not reach the plenum, but it stops the outside building up.
Do you need canopy cleaning in Letchworth Garden City?
Most canopies have troughs or channels that catch running grease. Left to fill up, they spill over, and grease ends up dripping from the canopy edge.
Signs it’s time to call us include:
- Drips from the canopy onto the range
- Greasy streaks across the canopy
- A filter housing caked in grease
- Grease filters blocking between washes
If you run catering at a healthcare site, such as a hospital like Fairfield Hospital about 1.8 miles north-west, the extract may need cleaning more often than a part-time kitchen.
Questions to ask before you book
- When they can work, and whether that is outside your opening hours
- If the quote is a fixed price or an estimate
- Exactly which parts of the system are covered
- When the next visit should be, and why

Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
