Hertfordshire · Kitchen extract cleaning
Kitchen extract cleaning in Shenley, Hertfordshire
Kitchen extract cleaning in Shenley from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- A TR19 certificate needed for the insurer
- An extract that no longer clears the smoke
- Heavy grease build-up inside the duct runs
What staff can safely do
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.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Kitchen duct cleaning in Shenley
The part of the system nobody sees is often the dirtiest. We reach horizontal runs and vertical risers through access panels, scraping heavy deposits by hand before degreasing. Anything out of reach is noted in the report, and new panels can be fitted. The work covers canopies and hoods, plenums and filters and extract fans, and people most often call us about a new tenancy or takeover with no cleaning history and ductwork thick with old, hardened grease. For TR19 kitchen extract cleaning in Shenley, you get one team and one number for every site, wherever you are in Hertfordshire.
What can be cleaned depends on what can be reached. Where a duct run has no panels, we say so on the report and can fit new ones.
Kitchens around a place like Shenley are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
The sign-off is always in writing: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

How we price kitchen extract cleaning
We quote each job individually. These are the things that affect it:
- How many systems or sites are involved
- The size of the system
- Site rules, permits and inductions
- Working hours and out-of-hours timing
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we’ll price it together.
What we need to know
What to send for a quote:
- Wide pictures of the system and the area around it
- The paperwork from the last visit, if you have it
- 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

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Empty any grease troughs or cups on the canopy
- Tell us when the extract starts to drip or smell
- Keep to the recommended cleaning interval
- Wipe the canopy down at the end of each day
We hand the kitchen back clean, with the sheeting removed and waste taken away. Grease and dirty water are collected and taken off site, and equipment can be switched back on once we’ve gone.
Tell whoever looks after the system when something changes. Drips, odours and fan noise often mean grease is building, and a grease thickness test can confirm it.
What kitchen extract cleaning looks like in Shenley
There are about 22 restaurants, cafés and canteens and about 5 sandwich bars and takeaways within about 1.5 miles of central Shenley, according to the Food Standards Agency’s register. Any of them cooking under a canopy is sending grease into its ductwork every service. Shenley sits within the area of 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. In Shenley, food businesses are inspected by environmental health officers from Hertsmere council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
A hospital like Shenley Hospital, about less than half a mile west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Bursars and site managers at schools such as Shenley Primary School tend to book extract cleaning for when the kitchen is empty.

Common questions in Shenley
Do you work in villages like Shenley?
Yes, Shenley is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Who is the fire and rescue service for Shenley?
Shenley is in the area of Hertfordshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
How long will the clean take?
It takes a few hours for a small kitchen, longer for a large system. The survey tells us how long your system will need.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
What information do you need?
A short description and a few pictures plus the address and your hours. If we need more, we’ll ask.
How much notice do you need?
The more notice, the better, particularly for night and weekend visits. Quotes typically come back within one working day, and emergencies are covered by our 24/7 line.
What’s the right cleaning interval for a kitchen extract?
That comes down mainly to daily cooking hours. BESA’s minimums run from every 3 months for heavy use to every 12 months for light use. We’ll recommend a date after measuring the grease.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
What we are called out for in Shenley
We often find duct sections that haven’t been cleaned since they were installed. The usual reason is a lack of access panels, so those sections were never reached. Grease in those sections keeps building out of sight.
Signs it’s time to call us include:
- Heavy grease build-up inside the duct runs
- A smoky, hot kitchen with weak extraction
- Grease drips onto cooking equipment
- An inspection that picked up a dirty extract
Volunteers running a hall kitchen near Church of St Martin, or anywhere in Shenley, may not know when the extract was last cleaned, and a grease test settles it.
Before booking anyone
- How they set the interval to the next visit
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Proof of insurance
- How areas they cannot reach will be recorded
What kitchen extract cleaning cannot fix
To be straight with you, there are a few things this work won’t fix:
- Blocked drains from a neglected grease trap (a separate service)
- A fan motor that has burnt out
- A canopy that is too small or a system that was badly designed
If in doubt, call 0345 646 2711 or drop us a line and we’ll say what we think before booking.
What the work covers
- Vertical risers
- Plenums and filters
- Horizontal duct runs
- Extract fans
- Discharge points
- Canopies and hoods
How it works
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 first, and floors and nearby surfaces are sheeted. The work itself takes as long as the system needs, from a few hours to several planned visits. In a place like Shenley, we fit the visit around your hours.
- We survey the system first, from your pictures and details or on a site visit.
- We measure the grease at set points along the system, then give you a fixed price.
- Once the kitchen has closed and the equipment has cooled, we sheet and protect the area.
- We clean the canopy, plenum, filters, ducts, risers, fan and discharge.
- Finally the system is re-tested and photographed, and the certificate and report follow.
Before we arrive
- Dig out any earlier paperwork for the system
- Clear loose items from the work area
- Arrange a key holder or contact on site
Getting a quote
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
