Why it’s worth doing now in Lemsford
Getting the canopy cleaned in Lemsford now saves a bigger job later. The work takes a few hours, depending on the size of the canopy and how much grease has built up, out of hours so service carries on. Left alone, grease keeps moving into the plenum and duct. It’s simpler to plan the work at Lemsford now than to arrange it in a hurry later.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.

Canopy cleaning in Lemsford
A kitchen team can wipe the outside of a canopy, but the seams, gutters and inner skin need more. We scrape the heavy deposits, then degrease the surfaces with methods that suit the build-up, using hot water or steam where it helps. Common call-outs are for a filter housing caked in grease and a canopy flagged at an environmental health inspection, across island canopies, grease gutters and wall canopies.
Work in a small place like Lemsford starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
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.

What we are called out for in Lemsford
Any canopy in Lemsford that is used for cooking will gather grease in the end. It’s fuel, sitting directly over the burners, which is why a flare-up near a dirty canopy is so dangerous.
Clients typically contact us when they notice something like this:
- Greasy streaks across the canopy
- A filter housing caked in grease
- A canopy that no longer draws the smoke away
- A canopy flagged at an environmental health inspection
If you run catering at a historic house or estate in the area (Digswell House is about 1.9 miles north-east), event kitchens in older buildings often have awkward duct runs that need planning.

How the visit works
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a few hours, depending on the size of the canopy and how much grease has built up. Somewhere like Lemsford, lanes, gates and parking are worth mentioning in advance.
- 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.
- With the filters out, the plenum and housing are cleaned back.
- 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
- Move anything stored near the system
- Let us know when the site is closed or quiet
- Find the previous report, if there is one
Ask for a quote
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.
Advice
Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Check and empty canopy gutters regularly
- Keep the fan on through service
- Wipe the canopy down at close every day
- Clean the baffle filters often
After the clean you get a photo report showing the canopy, plenum and housing before and after. The report lists what was cleaned and any part we couldn’t get to, 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.

What canopy cleaning can’t fix
In fairness, some problems need a different fix:
- Grease in the duct runs and risers behind the canopy
- A hood that does not cover the cooking line
- A fan that can’t pull enough air because it’s worn out
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we will tell you honestly before you book.

Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Lemsford: your questions answered
Do you clean school canteen extracts around Lemsford out of term?
Yes, and it’s the easiest time to do it. There are about 12 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Lemsford. Booking early in the term gives the best choice of holiday dates.
Is Lemsford within the area you cover?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
Can you clean the canopy outside our opening hours?
Only while we are working, and we work out of hours, so service isn’t affected. Evenings, overnight and weekends are all possible.
Do you clean the grease filters as part of a canopy clean?
The filters come out so the plenum behind them can be cleaned, and they’re cleaned before going back in. Any that are damaged are noted on the report.
Do you clean canopies in all kinds of kitchens?
Most commercial kitchen canopies, from one small hood to a long run of canopies. We work out the approach when we survey, from pictures or a visit.
Who is responsible for fire safety on the premises?
It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Call us any time and explain what’s happened.
Grease, kitchens and Lemsford
Food Standards Agency records include about 6 bars, pubs and nightclubs in and around Lemsford, up to about a mile and a half out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Lemsford get their food hygiene inspections from Welwyn Hatfield council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. Lemsford sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
School kitchens, at schools like Applecroft School for example, are normally cleaned in the holidays so no lunches are lost. If you run a church or community hall kitchen, near Church of St John the Evangelist or elsewhere in Lemsford, its extract still collects grease from every lunch and event.
Lemsford is about 2 miles west of Welwyn Garden City, in Hertfordshire. Across the AL8 area, we can take on canopy cleaning. Lemsford is one of 381 towns, villages and districts in Hertfordshire where we work for canopy cleaning. You can also see our page for London, about 21 miles away.

What the work involves, part by part
Pub and hotel kitchens
In a pub or hotel, the canopy is often in view of staff all day, so drips and smells soon become a daily nuisance. Cleaning the canopy and plenum sorts it.
Grease troughs and gutters
Some troughs drain to a cup or drawer, that is emptied and cleaned too, and we’ll show staff where it is.
