Hertfordshire · Kitchen extract cleaning
Pottersheath kitchen extract cleaning
Professional kitchen extract cleaning in and around Pottersheath, timed so the site keeps working and finished with a written report and photos.
- Fat running down the canopy edge
- Years of baked-on grease in the ducts
- A smoky, hot kitchen with weak extraction
Different parts, different methods
Grease filters
We clean the grease filters as part of the job, and refitted so they sit properly in the housing. Damaged ones are noted on the report.
Canopy and plenum
Whether it’s one hood or a long island canopy, each section is cleaned and photographed before and after.
Kitchen extract cleaning in Pottersheath, done properly
Cooking sends fat-laden vapour into the canopy with every service. As it cools, it clings to the inside of the ductwork and keeps building. That film is fuel, and a proper clean removes it before it becomes a fire risk. We are often asked to deal with an overdue clean flagged by an EHO or fire officer and a system with no record of a TR19 clean, across canopies and hoods, extract fans and horizontal duct runs. Whether you call it kitchen extract cleaning, TR19 cleaning or kitchen duct cleaning, it’s the job we do every week across Hertfordshire.
Each job starts with a look at where grease has built up: wet film or deposit thickness readings show which parts of the duct need the most attention, and readings afterwards go into your report.
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.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

How we price kitchen extract cleaning
We don’t publish a price list, because sites vary so much. What we look at:
- Site requirements such as sign-in and permits
- Whether several sites go on one quote
- The size of the system
- A single visit or a regular plan
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, call us on 0345 646 2711, or send details by email for straight advice and a fixed quote.
What we need to know
Many jobs can be priced from photos and some basics. Useful things to send:
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
- Any previous report or certificate

Pottersheath questions
Which fire authority looks after Pottersheath?
That is Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Will you come out to Pottersheath?
Yes, Pottersheath is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
How often should a kitchen extract be cleaned?
The minimum is set by BESA guidance on daily use, from 3-monthly to 12-monthly. Heavy frying and grilling can mean shorter intervals, which grease thickness testing will show.
Can you quote from photos?
Often, yes. With good photos, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Do insurers need proof of extract cleaning?
Extract grease is fuel for a kitchen fire, so many insurers want evidence it’s being cleaned to TR19. Our certificate and photo report give you that evidence.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
How long does a kitchen extract clean take?
Allow anything from a few hours to a full night, depending on the size of the system. The survey tells us how long your system will need.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it doesn’t spread.
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Diarise the next clean as soon as you get the certificate
- Tell us when the extract starts to drip or smell
- Keep the baffle filters clean
- Run the extract fan throughout cooking
A TR19 certificate notes the date, the location and the technician. File it with the fire risk assessment and the maintenance log so it’s ready when anyone asks to see it.
Keep the fan on throughout service. Cooking with the extract off lets grease and heat settle in the canopy, and the next clean has more to do.
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
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.
What a clean will not put right
It’s worth knowing the limits before booking:
- Damaged duct sections that need replacing
- A broken extract fan that will not run
- A canopy that’s too small or a system that was badly designed
If in doubt, call 0345 646 2711, or send details by email and we will say what we think before booking.
What we work on in Pottersheath
- Plenums and filters
- Horizontal duct runs
- Vertical risers
- Extract fans
- Canopies and hoods
- Discharge points
What happens on the day
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a few hours for a small kitchen, longer for a large system. Visits to a village like Pottersheath are booked in advance, at a time that suits whoever runs the site.
- Diagnosis comes first, with a survey of the system and how it’s reached.
- Grease readings set the baseline, and a fixed quote follows.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- The treatment: heavy grease scraped out, then every part degreased to TR19® Grease.
- The sign-off: post-clean readings, a TR19 certificate and a photo report with the next clean date.
Getting ready for the visit
- Mention any parking or loading restrictions
- Tell us the best time to work, such as after service or at a weekend
- Dig out any earlier paperwork for the system
