For landlords and multi-site operators
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Ductwork cleaning in Bendish
Nobody sees duct grease building, so nobody notices it until something goes wrong. Flames pulled in from the cooking line can ignite it, carrying a fire along the duct and into rooms far from the kitchen. Cleaning the duct takes that fuel away. The work covers bends and junctions, access panels and attenuators, and the jobs we see most are an insurer asking for TR19 evidence and hardened, baked-on grease in long horizontal runs.
In a village or hamlet like Bendish, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Kitchen extracts in Bendish
Food Standards Agency records include about 3 pubs, bars and clubs across Bendish and its immediate surroundings (about a mile and a half). A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Hertfordshire Fire and Rescue Service covers Bendish. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Bendish, food businesses are inspected by environmental health officers from North Hertfordshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
If you run catering at a healthcare site, such as a hospital like Lister Hospital about 5.1 miles north-east, the extract may need cleaning more often than a part-time kitchen. Bursars and site managers at schools such as Breachwood Green Junior Mixed and Infant School tend to book extract cleaning for when the kitchen is empty.

FAQs for Bendish
Can you clean school kitchen extracts in Bendish during the holidays?
Yes, out-of-term visits are normal for schools. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Bendish. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you work in Bendish outside opening hours?
Yes, we can come after you close and finish before you open. The work in Bendish can fit around your hours. When you give us a ring on 0345 646 2711, or email photos, mention when the site is quiet.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
How can I tell if my extract ducts are dirty?
Start with the date of the last clean. If it’s overdue, or there isn’t one, a clean is due, and grease readings will confirm how urgent it is.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
Is a quote from photos possible?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How do you clean inside the ductwork?
We survey the route, test the grease, then open the access panels. We clean the runs and risers section by section, then the readings are repeated.
Leave it or put it right?
Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. Anywhere that reaches 500 microns or more needs immediate spot cleaning. Putting off the clean only pushes readings higher. Equipment tucked in a roof space or outbuilding near Bendish rarely gets looked at unless someone books it.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.

Between visits
A little care between visits keeps the system in better shape. We recommend:
- Tell us if grease leaks from the ductwork
- Have the grease measured if cooking hours go up
- Make sure filters are seated properly
- Ask us about extra access panels where sections cannot be reached
You’ll have a recommended date for the next clean, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Keep the fan on throughout service. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
How we price ductwork cleaning
The quote reflects the site in front of us. We consider:
- The scale of the work
- How many systems or sites are involved
- A single visit or a regular plan
- Working hours and out-of-hours timing
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
What to send for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- 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
- Where the site is and what kind of site it is
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Photos of the system and how to reach it help us plan a visit to Bendish.
- First we diagnose: the route, the access and the grease levels.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, pictures and a recommended next clean date complete the job.
How to prepare
- Name a contact who can let us in at the agreed time
- Clear loose items from the work area
- Find the previous report, if there is one

Signs you need ductwork cleaning in Bendish
Grease settles fastest where the air slows down. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
Common reasons sites call us include:
- Fat dripping from the ductwork
- Gaps where access panels were never fitted
- Thick crusts of old grease along the duct
- An insurer asking for TR19 evidence
Historic houses near Bendish, such as Shaw's Corner about 3.7 miles south-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
