TR19 kitchen extract cleaning in Chaulden
A kitchen extract system is far more than the canopy you can see. Behind it sit the plenum and grease filters, then the ductwork, risers, extract fan and discharge, and each part collects grease. A TR19® Grease clean deals with the whole route, not only the parts on show. The work covers canopies and hoods, extract fans and vertical risers, and common reasons people get in touch are an inspection that picked up a dirty extract and a kitchen taken over without any extract records. Most calls from Chaulden come after an insurer, an EHO or a fire officer asks to see the last TR19 certificate. We handle the clean and the paperwork in one visit.
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.
Size doesn’t change the work: a kitchen in a place like Chaulden gets the whole system cleaned, canopy to discharge. The visit is booked around your opening hours, and the journey is planned ahead.
The sign-off is always in writing: 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.

What happens on the day
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes anything from a few hours to a full night, depending on the size of the system, and we clear up before we go. In a place like Chaulden, we fit the visit around your hours.
- We start with a survey, so we know every part of the system before we quote.
- We measure the grease at set points along the system, then give you a fixed price.
- On the day, cooking equipment is switched off and left to cool, and everything nearby is sheeted.
- We clean the canopy, plenum, filters, ducts, risers, fan and discharge.
- Finally the system is re-tested and photographed, and the certificate and report follow.
Preparing for the visit
- Have your last certificate or report to hand

How the job changes from site to site
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.
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.

FAQs for Chaulden
Can you clean school kitchen extracts in Chaulden during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 15 schools and colleges with food registrations within roughly a mile and a half of Chaulden. Just call us on 0345 646 2711 or send us an email with your term dates and we will plan around them.
Do you cover smaller places like Chaulden?
Yes, Chaulden is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
How much does kitchen extract cleaning cost in Chaulden?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we will usually reply within one working day.
Does the law say I must clean to TR19?
TR19 is not written into law, but the responsible person still has a legal duty under the Fire Safety Order 2005. Insurers, fire officers and EHOs look to TR19 as the standard, and many policies require it.
What’s the right cleaning interval for a kitchen extract?
The minimum is set by BESA guidance on daily use, from 3-monthly to 12-monthly. Kitchens that fry or grill a lot may need cleaning sooner, and readings will tell you.
What information do you need?
A short description and a few pictures plus the address and your hours. We’ll ask for anything else we need.
Do you clean the whole extract system or just the canopy?
We clean every part the grease travels through. Canopy, plenum, filters, ductwork, risers, fan and discharge are all included, reached through access panels where necessary.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Fixed quotes for kitchen extract cleaning in Chaulden
The survey tells us what the work involves. We look at:
- How easy every part is to reach
- Whether several sites go on one quote
- What state the system is in
- The size of the system
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before we start.
What we need to know
You don’t need the technical terms. It helps if you can send:
- Photos showing the whole system and its surroundings
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
- Any previous report or certificate
For a fixed quote, give us a ring on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You will usually have a quote within one working day.
Between visits
To keep the system working properly between visits:
- Keep to the recommended cleaning interval
- Keep the extract on whenever the range is lit
- Report grease drips, smells or fan noise right away
- Refit filters properly after cleaning
Any section without access is marked on the report. A TR19 report should record what wasn’t cleaned as well as what was, and we can fit access panels so it’s reached next time.
Clean the grease filters often, not just on clean day. Clean, well-fitted filters catch more fat before it reaches the duct, so the ductwork stays cleaner for longer.
Common problems we fix in Chaulden
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 from there it travels on to the fan.
Any of these means the system needs a check-up:
- Stale cooking odours from the system
- Fat running down the canopy edge
- An overdue clean flagged by an EHO or fire officer
- An extract that has never been cleaned to TR19
If you run a café or takeaway near Hemel Hempstead station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
