TR19 kitchen extract cleaning in Haldens
We cover Haldens for TR19 Grease cleaning of complete kitchen extract systems, from canopy to discharge. Out-of-hours visits, a fixed quote and a written report with photos on every job.
- Missing paperwork after a change of operator
- A TR19 certificate needed for the insurer
- Rancid smells from grease in the duct
Keeping the system healthy
After the visit, a few habits help the work last:
- Clean grease off the canopy surfaces regularly
- Diarise the next clean as soon as you get the certificate
- Keep grease collection points emptied
- Keep the TR19 certificate and photo report in the maintenance log
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 pictures. A TR19 certificate follows, issued through the BESCA Vent Hygiene Elite portal.
Stick to the cleaning interval on the certificate. BESA guidance links the minimum interval to daily cooking hours, so a change in hours may mean a change in interval, and grease readings will show it.
Kitchen extract cleaning for kitchens and businesses in Haldens
Not sure when the extract was last cleaned, or by whom? Just call us on 0345 646 2711, or email photos with photos of the canopy and filters, and you’ll have a fixed quote for kitchen extract cleaning in Haldens, usually within one working day. The work covers vertical risers, horizontal duct runs and canopies and hoods, and the jobs we see most are grease drips onto cooking equipment and ductwork thick with old, hardened grease. Some call it canopy cleaning, others extract cleaning or duct cleaning, but in Haldens, as everywhere, the insurer wants the full system cleaned, not just the hood.
Before we clean, we look at where the grease is: grease readings at set points tell us where the heaviest deposits are, and readings afterwards go into your report.
For a smaller kitchen near Haldens, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Common problems we fix in Haldens
Grease in the extract matters because it burns. A flare-up on the range can be drawn up into the canopy and duct, where burning grease can carry a fire along the ducts and into other parts of the building. That’s why controlling extract grease belongs in the fire risk assessment.
Look out for these warning signs:
- Rancid smells from grease in the duct
- Grease dripping from the canopy or filters
- Cleaning needed before an insurance renewal or survey
- An extract that has never been cleaned to TR19
For kitchens close to Welwyn North station, where the day often starts early and ends late, the extract can be cleaned overnight.
Questions to ask before booking
- Proof of insurance
- What hours they’ll be on site
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- How they set the interval to the next visit
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes a single shift for most kitchens, with long duct runs and tall risers needing more time. Your opening hours decide when we come to Haldens, not ours.
- First comes a survey of the whole system, by photos or a visit.
- Set points are tested for grease thickness and the quote is fixed before any work starts.
- Once the kitchen has closed and the equipment has cooled, we sheet and protect the area.
- 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.
Preparing for the visit
- Move anything stored near the system
- Mention any locked doors, roof access or ceiling voids
- Make sure someone can let us in and lock up afterwards
Ask for a quote
Getting a quote doesn’t take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

How the job changes from site to site
Extract fan and discharge
Some systems have attenuators to cut noise, and they hold grease. Where they can be cleaned, they are, and the report notes anything that cannot.
Canopy and plenum
Behind the grease filters sits the plenum, which daily cleaning never reaches. We take the filters out and clean the plenum and housing thoroughly.
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Managing agents and facilities teams in Haldens
We also work for facilities teams across offices, schools and healthcare in Haldens and across Hertfordshire. Larger estates can be phased building by building around the people who use them.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Your questions about kitchen extract cleaning in Haldens
Which council inspects kitchens in Haldens?
Food hygiene inspections in Haldens are carried out by Welwyn Hatfield council. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can you come to Haldens after we close?
Yes, nights and weekends are routine for us. It means the site in Haldens keeps running as normal. Just call us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
How long will the clean take?
Length of duct, grease levels and access all affect it. As a guide, it takes a few hours for a small kitchen, longer for a large system.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we will quote them together.
Will I get a certificate after the clean?
You receive a TR19 certificate and a photo report. The certificate is issued through the BESCA Vent Hygiene Elite portal, and the report includes before and after pictures, grease readings and the recommended next clean date.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Which parts of the extract do you clean?
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.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
What a clean won’t put right
Not every problem is solved by kitchen extract cleaning, and we’d rather say so up front. It will not put right:
- An undersized canopy or fan
- A fan motor that has burnt out
- Ductwork that is corroded, split or leaking (that is for a ductwork contractor)
If in doubt, call 0345 646 2711 or email us and we will say what we think before you book.
Where we work
- Vertical risers
- Plenums and filters
- Horizontal duct runs
- Discharge points
- Canopies and hoods

Every kitchen in that count with a canopy has a full extract system, canopy to discharge, to keep clear of grease. Kitchens in Haldens get their food hygiene inspections from Welwyn Hatfield council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked.
