How we handle canopy cleaning in Nup End Green
The canopy is the part of the extract everyone in the kitchen sees. It’s also the first place cooking vapour meets, so grease gathers on its inner skin, seams and gutters. We clean it inside and out, along with the plenum and filter housing behind it. The work covers island canopies, grease gutters and baffle filters, and people most often call us about condensation and grease dripping together and heavy deposits behind the grease filters.
Work in a small place like Nup End Green 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.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Wash or exchange the filters on a regular cycle
- Report new drips or smells from the canopy
- Check filters are not leaving gaps
- Check all filters are fitted before service
The kitchen is handed back clean, with the sheeting gone and the waste removed. Filters are back in place and seated properly, and the kitchen is ready to cook.
A daily wipe of the hood keeps fresh grease from baking on. It won’t replace a professional clean, but it slows the build-up you can see.
Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Leave it or put it right?
Drips from a dirty canopy land on the cooking line. It’s a food hygiene concern as much as a fire concern, and environmental health officers look at the cleanliness of equipment, extraction included. Equipment tucked in a roof space or outbuilding near Nup End Green rarely gets looked at unless someone books it.

The process
We turn up 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 before we start, and floors and nearby surfaces are sheeted. On site, it takes an hour or two for one small canopy, longer where there are several. Pictures of the system and its access let us plan the work in Nup End Green before we set off.
- We start by checking the canopy, filters and plenum.
- Equipment below is switched off and left to cool, then sheeted.
- 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 photos go into your report.
Before we arrive
- Name a contact who can let us in at the agreed time
- Dig out any earlier paperwork for the system
- Move anything stored near the system

Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
Advice
What a clean won’t put right
It’s worth knowing the limits before booking:

- Ductwork and fans beyond the canopy (those need a full TR19 clean)

How we price canopy cleaning
A fixed price needs a few facts first. We look at:
- The size of the system
- Site requirements such as sign-in and permits
- The number of sites or systems
- Parking and loading at the site
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before any work starts.
Helping us quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Your last certificate, test record or report
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Your questions about canopy cleaning in Nup End Green
Can school kitchens in Nup End Green be cleaned in the holidays?
Yes, holiday work suits schools best. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Nup End Green. Just call 0345 646 2711, or email photos with your term dates and we will plan around them.
Will you come out to Nup End Green?
Yes, Nup End Green is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
How much does canopy cleaning cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before any work starts.
What causes grease to drip from the hood?
A canopy only holds so much grease. When the gutters fill, it overflows onto the range, often mixed with condensation. A thorough clean stops it.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Do you offer emergency callouts?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then give us a ring on 0345 646 2711, or send details by email.
What the work involves, part by part
Wall canopies
A long wall canopy may hold several sections of filters. Each section’s plenum and housing is cleaned in turn, with pictures for each.
Plenums and filter housings
Filter housings hold the filters in place, and their channels fill with grease. Clean housings let the filters seat properly and leave no gaps.
What canopy cleaning looks like in Nup End Green
Look up Nup End Green on the FSA’s food hygiene register and you’ll find about 3 cafés, restaurants and staff canteens in and around Nup End Green, up to about a mile and a half out. Each canopy in those kitchens catches grease on the inside of the hood and behind the filters. The fire and rescue service for Nup End Green is 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. Kitchens in Nup End Green get their food hygiene inspections from North Hertfordshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Knebworth House is about 0.6 miles north-east), access may need planning. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Nup End Green is Lister Hospital, about 4.1 miles north. Volunteers running a hall kitchen near Church of St Mary and St Thomas, or anywhere in Nup End Green, may not know when the extract was last cleaned, and a grease test settles it.
