Kitchen extract cleaning in North Mymms
Any kitchen we clean in North Mymms gets exactly the same specification as everywhere else we work. The job starts with a survey and grease readings, then works through canopy, plenum, filters, ductwork, fan and discharge. At the finish there’s a TR19 certificate and a before and after photo report. If you have an extract that has never been cleaned to TR19 and heavy grease build-up inside the duct runs, we can put it right, from canopies and hoods, vertical risers and plenums and filters onwards. Whether you call it kitchen extract cleaning, TR19 cleaning or kitchen duct cleaning, it’s the job we do every week across Hertfordshire.
A kitchen running fryers and chargrills all day builds up grease much faster than one that mostly steams and boils, so we look at the menu as well as the opening hours when we suggest the next date.
Work in a small place like North Mymms starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
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.

Why act early in North Mymms
There’s no law that names TR19, but the Fire Safety Order 2005 still applies. It puts a duty on the responsible person to assess and reduce fire risk, which in a kitchen includes the grease in the extract. TR19 is the benchmark insurers, fire officers and EHOs look to. It’s worth booking a check, because nobody sees inside a duct day to day.
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.

North Mymms questions
Which environmental health team covers North Mymms?
In North Mymms, it’s Welwyn Hatfield council that carries out food hygiene inspections. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Which fire service covers North Mymms?
That’s Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
How do you keep the site clean during the work?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What does a TR19 kitchen extract clean include?
Everything from canopy to discharge: the canopy, the plenum behind the filters, the filters, horizontal ducts, vertical risers, the fan and the discharge, plus attenuators where fitted. Any part without access is noted.
Do insurers need proof of extract cleaning?
Because a dirty extract can spread a fire through a building. Many policies say the extract must be cleaned to TR19, and a claim may be reduced without proof, so keep every certificate.
What information do you need?
A short description and a few photos, with the address and opening hours. We’ll ask for anything else we need.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. A fixed quote follows.
Are you accredited for kitchen extract cleaning?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 sit alongside that, and we are fully insured.

Any of them serving cooked food has an extract to keep clean, from canopy to discharge. North Mymms is covered by Hertfordshire Fire and Rescue Service.

A dated certificate in the maintenance file answers the question before it’s asked.

Fixed quotes for kitchen extract cleaning in North Mymms
You’ll get a fixed price before we start. It takes into account:
- Site rules, permits and inductions
- A single visit or a regular plan
- What state the system is in
- The number of sites or systems
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.
Asking for a quote
Before you ask for a quote, gather:
- Any previous report or certificate
- The times we could work without disrupting the site
- Problems your staff have spotted
- Photos showing the whole system and its surroundings
We don’t publish a price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, call us on 0345 646 2711 or use the quote form.
What your team can do, and what needs us
If your staff spot something 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 can diagnose it and quote.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
What we do, step by step
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before we start, and the area around the work is covered and protected. The work itself takes as long as the system needs, from a few hours to several planned visits. If the van will struggle with a lane or gateway near North Mymms, let us know and we’ll plan around it.
- We start with a survey, so we know every part of the system before we quote.
- Set points are tested for grease thickness and the quote is fixed before work begins.
- On the day, cooking equipment is switched off and left to cool, and everything nearby is sheeted.
- Canopy, plenum, filters, duct runs, risers, fan and discharge are all cleaned to TR19® Grease.
- Finally the system is re-tested and photographed, and the certificate and report follow.
How to prepare
- Let us know about permits to work or site inductions
- Let us know about parking and loading
- Clear loose items from the work area
How to get a quote
The quickest way to a quote is to send photos: 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.

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.

Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Book the next clean before the date on the report
- Empty any grease troughs or cups on the canopy
- Refit filters properly after cleaning
- Keep the cleaning records where you can find them
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.
Clean the grease filters often, not just on clean day. A filter that is clean and seated properly stops more grease getting into the plenum, which slows build-up further down the system.
Common problems we fix in North Mymms
Grease filters are the first line of defence, and they’re often the weak point. Filters that are bent, badly fitted, missing or left uncleaned let more fat into the plenum and duct, and it does not stop until it reaches the fan.
Common reasons sites call us include:
- An inspection that picked up a dirty extract
- Grease smells coming from the extract
- A smoky, hot kitchen with weak extraction
- Years of baked-on grease in the ducts
Commuter trade near Brookmans Park station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
