How we handle canopy cleaning in Hitchin
We’ve been cleaning kitchen canopies since we started trading in 2009. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we are fully insured, with CHAS, SafeContractor and ISO 9001. Common call-outs are for a hood coated in old grease and grease channels that no longer drain, on grease gutters, canopy light fittings and plenum chambers.
In a town like Hitchin, most of the kitchen extracts we’re asked about belong to restaurants, cafés, pubs, takeaways and school or care home kitchens. Whatever the kitchen, the canopy, filters, duct and fan all collect grease.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Canopy cleaning around Hitchin
Food Standards Agency records include about 37 pubs, bars and clubs and about 4 hotels, B&Bs and guest houses in and around Hitchin, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Food hygiene inspections in Hitchin are the job of North Hertfordshire council’s environmental health team. 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. Hitchin is covered by Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Church and community hall kitchens, near Church of the Holy Saviour or anywhere around Hitchin, are easy to forget, but their extracts collect grease like any other. For schools such as Hitchin Girls' School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

Looking after it afterwards
Once we have finished, these simple steps help:
- Leave the extract running until cooking stops
- Check all filters are fitted before service
- Report new drips or smells from the canopy
- Clean the baffle filters often
Keep the photo report with your maintenance log, so it’s ready when an EHO, insurer or fire officer asks. Before and after photos speak for themselves.
Wipe the canopy surfaces at the end of each day. It will not replace a professional clean, but it slows the build-up you can see.
How it works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a few hours, depending on the size of the canopy and how much grease has built up. Send us pictures of the system and we can plan most of a visit in Hitchin before we arrive.
- 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.
- Inside and out, the canopy and its grease channels are degreased.
- Filters go back, the area is cleaned down and pictures are taken.
How to prepare
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one
- Let us know when the site is closed or quiet
Getting a quote
The quickest way to a quote is to send pictures: 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.

What happens if it’s left?
In Hitchin, as elsewhere, a greasy canopy is one of the first things an inspector sees. Keeping it clean shows the rest of the kitchen is being looked after and keeping it that way is easier than catching up. Dealt with now, it’s a planned visit around your hours rather than a callout when the site needs to be open.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, call us on 0345 646 2711 or send us an email for straight advice and a fixed quote.

Common questions in Hitchin
Which fire authority looks after Hitchin?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Hitchin. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Who carries out food hygiene inspections in Hitchin?
In Hitchin, it’s North Hertfordshire council that carries out food hygiene inspections. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Do you work in Hitchin?
Yes. Our technicians work in Hitchin, within the South East and London area we cover.
Do you provide photos of the cleaned canopy?
A photo report, with before and after pictures of the canopy and plenum. The report includes a recommended next clean date.
Which canopies and hoods do you clean?
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.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
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.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What affects the quote in Hitchin
Sites vary more than people expect. The main factors:
- Whether several sites go on one quote
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before work begins.
What we need to know
To help us quote quickly, please include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.
What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
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.
Other services in Hitchin
How the job changes from site to site
Plenums and filter housings
Behind neglected filters, the plenum can be heavily coated. We remove thick grease by hand, then degrease.
Pub and hotel kitchens
A hotel or pub kitchen can rarely close for long. Canopy cleans are done late at night or early in the morning so the kitchen keeps trading.
What we’re called out for in Hitchin
The canopy takes the hottest, wettest air in the kitchen. Grease from the vapour lands on the canopy’s inner surfaces, its joints and its filters before what gets through reaches the plenum.
Keep an eye out for any of the following:
- Grease channels that no longer drain
- Greasy streaks across the canopy
- Filters that never seem to stay clean
- Poor capture at the hood
For kitchens close to Hitchin station, where the day often starts early and ends late, the extract can be cleaned overnight.
