- Poor airflow at the canopy
- Heavy grease build-up inside the duct runs
- Grease dripping from the canopy or filters
The process
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes one visit for most kitchens, while large or complex systems may need more than one. The timing of a visit to South Mimms is set by you, and the travel is our side of the planning.
- First the diagnosis: a survey of the whole system and its access points.
- We record grease levels at set points, then fix the price.
- We arrive after close, protect the area and contain the waste.
- The treatment: heavy grease scraped out, then every part degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
Preparing for the visit
- Let us know about parking and loading
- Mention any locked doors, roof access or ceiling voids
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
We don’t publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, give us a ring on 0345 646 2711, or send details by email.

What affects the cost of kitchen extract cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Any permits to work or inductions
- The scale of the work
- Whether we need access equipment or extra panels
- The condition of the system
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- Any previous report or certificate
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
- Your opening hours and when the area is out of use
Photos are the quickest way to a quote: 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 many jobs can be priced from that alone.
What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Grease, kitchens and South Mimms
Look up South Mimms on the FSA’s food hygiene register and you’ll find about 13 restaurants, cafés and works canteens and about 4 takeaways and sandwich shops across South Mimms and its immediate surroundings (about a mile and a half). Any of them cooking under a canopy is sending grease into its ductwork every service. South Mimms is covered by Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. In South Mimms, food businesses are inspected by environmental health officers from Hertsmere council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Wyllyotts Manor, about 1.6 miles east, is one of the historic houses near South Mimms; if you run event catering at a venue like that, cleans can be booked between functions. Church and community hall kitchens, near Church of St Giles or anywhere around South Mimms, are easy to forget, but their extracts collect grease like any other.
South Mimms is about 2 miles west of Potters Bar, in Hertfordshire. Whether your site is in the middle of South Mimms or further out, we cover kitchen extract cleaning for every kind of premises, from a single unit to a large public building. Our area takes in 381 places across Hertfordshire, from busy centres to quieter spots. We also work in London, around 15 miles away.

How the job changes from site to site
Ductwork and risers
Grease builds up most where the duct turns. Those are among the points where we take readings before and after, so the report shows the difference.
Grease filters
Gaps around filters let fat through to the duct. We check they fit as they should when we refit them, and flag any that don’t.
Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Don’t let the canopy gutters overflow
- Switch the fan on before cooking starts
- Give the canopy a daily wipe
- Book the next clean before the date on the report
When the clean is finished, grease readings are taken again at the same points, so you can see the difference in numbers as well as photos. Your TR19 certificate is then issued through the BESCA Vent Hygiene Elite portal.
Wipe the canopy down regularly and empty grease troughs or collection points. A daily wipe is not a deep clean, but it helps between visits.
When it’s something else
It’s worth knowing the limits before booking:
- Blocked drains from a neglected grease trap (a separate service)
- Damaged duct sections that need replacing
- An undersized canopy or fan
If you are not sure, just call 0345 646 2711, or send details by email and we will give you a straight answer.

South Mimms: your questions answered
Who inspects food businesses in South Mimms?
Kitchens in South Mimms are inspected by Hertsmere council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can a school canteen extract in South Mimms be done out of term time?
Yes. The holidays are the usual time for school work. There are about 4 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of South Mimms. You can call us on 0345 646 2711 or drop us a line with the dates the site is empty.
When do you clean the extract?
When the kitchen is closed, at whatever time suits you. The equipment is switched off and left to cool, and we hand the kitchen back ready for the next service.
What paperwork comes with a kitchen extract clean?
Yes, a TR19 certificate, along with a photo report. The report lists what was cleaned, anything we couldn’t reach and when the next clean is due.
Do you work in South Mimms?
Yes. We cover South Mimms and the rest of Hertfordshire, within our South East and London area. To book, call 0345 646 2711, or email photos.
Do you clean the whole extract system or just the canopy?
Everything from canopy to discharge: canopy inside and out, plenum, grease filters, ductwork, risers, extract fan and discharge, plus attenuators where fitted. Anything we cannot reach is recorded on the report.
Why do insurers care about extract cleaning?
Extract grease is fuel for a kitchen fire, which is why many insurers require TR19 cleaning. Each clean gives you a certificate and photo report to show them.
Are you accredited for kitchen extract cleaning?
We clean to BESA TR19® Grease as a BESCA Vent Hygiene Elite member, and certificates go through the BESCA Vent Hygiene Elite portal. We’ve been trading since 2009.

What we’re called out for in South Mimms
How fast grease builds up depends mostly on how long the kitchen cooks each day. Under BESA guidance, heavy use of 12 to 16 hours a day means a clean at least every 3 months, moderate use every 6 months and light use every 12. Those are minimums, and grease readings can show a kitchen needs cleaning sooner.
These are the problems we see most often:
- Years of baked-on grease in the ducts
- A smoky, hot kitchen with weak extraction
- Proof of cleaning requested by an insurer
- A system with no record of a TR19 clean
Healthcare kitchens, like those at hospitals such as Shenley Hospital (about 2.7 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands.
