Hertfordshire · Canopy and hood cleaning
Letty Green canopy cleaning
For deep cleaning of kitchen canopies, hoods, plenums and grease filters, inside and out in Letty Green, one call is all it takes: survey, fixed quote, work and sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Grease dripping from the canopy edge
- Canopy gutters full of old fat
- Greasy streaks across the canopy
What happens if it’s left?
Drips from a dirty canopy land on the cooking line. That’s a hygiene problem as well as a fire one, and environmental health officers look at the cleanliness of equipment, extraction included. In a small place like Letty Green, a system that fails can take a site out of use.
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and the price is agreed before work begins.
What you get with us
- Fully insured
- One contact for all your sites in London and the South East
- Evenings, overnight and weekends, plus 24/7 emergency callout
- Ventilation hygiene specialists since 2009

About our canopy cleaning in Letty Green
If the canopy in Letty Green is dripping, sticky or overdue a clean? Send us a photo of the hood and filters when you ring 0345 646 2711, or email photos, and we will send you a fixed quote for canopy cleaning, typically within one working day. Typical jobs include a plenum thick with grease behind the filters and overflowing grease troughs and gutters, across grease gutters, plenum chambers and baffle filters.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What canopy cleaning looks like in Letty Green
It’s East Hertfordshire council that sends environmental health officers to food businesses in Letty Green. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. We cover Letty Green, about 20 miles from central London, as part of our work across London and the South East. Evening, overnight and weekend visits are all possible.
Healthcare kitchens, like those at hospitals such as Queen Elizabeth II Hospital (about 2.2 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands. Church and community hall kitchens, near St John's Church or anywhere around Letty Green, are easy to forget, but their extracts collect grease like any other.
Letty Green is about 3 miles south-east of Welwyn Garden City, in Hertfordshire. We carry out canopy cleaning for businesses, landlords and public buildings in Letty Green and the rest of Hertfordshire. We cover 381 places across Hertfordshire, from busy centres to quieter spots. You can also see our page for London, about 20 miles away.
Work in SG14 is surveyed, quoted and booked the same way as anywhere else. You will find streets such as Station Road, Woolmers Lane and Chapel Lane, and we cover them all for canopy cleaning. If your site is just outside Letty Green, we cover East End Green (1 mile east), Staines Green (1 mile north-east), Hertingfordbury (1 mile north-east), Essendon (2 miles south-west) and Little Berkhamsted (2 miles south). Larger places within reach include Watford (14 miles south-west), Hemel Hempstead (14 miles west), Stevenage (9 miles north), St Albans (8 miles west), Bishop's Stortford (14 miles north-east) and Welwyn Garden City (3 miles north-west).
Landmarks near Letty Green
Around Letty Green, our work takes us to kitchens and buildings near The Sele School and Panshanger Park and the streets around them. Letty Green’s nearest station is Hertford North station, roughly 2.2 miles north-east. A little further out are Howard Centre (3.2 miles north-west) and Mcmullen & Sons Brewery Museum (2.6 miles north-east). The countryside around Letty Green includes Willowmead.
Do you need canopy cleaning in Letty Green?
A canopy with gaps around its filters lets grease straight through. 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
- An EHO comment about the canopy
- Condensation and grease dripping together
- Smoke hanging around the canopy during service
If your kitchen is in a listed or historic building, like the houses around Letty Green (Hatfield House is about 3.4 miles south-west), fitting access panels needs care.
What your quote should include
- How VAT is shown on the quote
- Proof of insurance

Managing agents and facilities teams in Letty Green
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Common questions in Letty Green
Which environmental health team covers Letty Green?
Kitchens in Letty Green are inspected by East Hertfordshire council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Is Letty Green within the area you cover?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Ring any time and tell us what’s happened.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
Do you clean the grease filters as part of a canopy clean?
We take them out, clean them and put them back. Between cleans, a filter exchange service can keep them in good order.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.
Do you look at the system first?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
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 they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Aftercare tips
To keep the system working properly between visits:
- Make sure filters sit tight in the housing
- Run the extract the whole time you are cooking
- Check all filters are fitted before service
- Flag any change in how the canopy behaves
We point out anything we noticed while the canopy was apart: damaged filters, gaps around the housing or troughs that need emptying more often. It’s a short list of what to watch, not a sales pitch.
Clean filters are the canopy’s first defence. Keep them on a regular cleaning or exchange cycle, and make sure they’re all in place before cooking. Less grease gets into the plenum as a result.
What a clean will not put right
Some problems need a different service or another trade:
- Grease filters too damaged to refit (they need replacing)
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
- A fan that can’t pull enough air because it’s worn out
If you are not sure, just phone us on 0345 646 2711 or use the quote form and we will give you a straight answer.

What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes part of a shift for most kitchens, more where there are several canopies or heavy deposits, and the area is cleaned down before we leave. The timing of a visit to Letty Green is set by you, and the travel is our side of the planning.
- We start by checking the canopy and what’s behind its filters.
- Equipment is turned off and cooled, and the area under the canopy is protected.
- Thick grease is scraped away before the canopy is degreased.
- Plenum, housing, troughs and canopy are all cleaned and checked.
- The canopy is signed off with before and after pictures and a next clean date.
How to prepare
- Let us know about parking and loading
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool
