TR19 kitchen extract cleaning in California
Think of it as a health check for the kitchen’s airways: diagnose with a survey, treat with a thorough clean, then sign it off. That clean bill of health comes as a TR19 certificate and a photo report, issued through the BESCA Vent Hygiene Elite portal. The work covers vertical risers, horizontal duct runs and discharge points, and the jobs we see most are a system with no record of a TR19 clean and a smoky, hot kitchen with weak extraction. When a restaurant in California asks for duct cleaning, it’s nearly always the kitchen extract they mean, and that’s exactly what we do: canopy to fan, to TR19® Grease.
Most kitchens in California fall into one of BESA’s three bands: every 3 months for 12–16 hours, every 6 months for 6–12 hours and every 12 months for 2–6 hours, with grease readings setting the real interval.
For a smaller kitchen near California, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What affects the cost of kitchen extract cleaning
Your quote is based on your site. We consider:
- A single visit or a regular plan
- Whether several sites go on one quote
- Site rules, permits and inductions
- How big the system is
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
Helping us quote
To speed up the quote, send us:
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To get going, call 0345 646 2711, or email photos.

Part by part
Ductwork and risers
Risers take the extract up through floors to roof level, and grease runs down their walls and pools at the base. They’re cleaned through access points along their height.
Schools, hospitals and care homes
Institutional kitchens tend to cook to set hours, so cleans can be planned for holidays or quiet times. The certificate and report suit estates and compliance files.
Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Clean grease off the canopy surfaces regularly
- Don’t let the canopy gutters overflow
- Make sure every filter is fitted before cooking
- Keep the baffle filters clean
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 to hand when an insurer, fire officer or EHO asks.
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.
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
How it works
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes a few hours for a small kitchen, longer for a large system. Getting to the system matters more than parking in a place like California, so let us know how to reach it.
- First the diagnosis: a survey of the whole system and its access points.
- 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.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Find the previous report, if there is one
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
For a fixed quote, phone us on 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You will typically have a quote within one working day.
Advice
Managing agents and facilities teams in California
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Signs you need kitchen extract cleaning in California
Grease in the extract matters because it burns. Flames from a pan or grill can be pulled into the canopy by the fan, where burning grease can carry a fire along the ducts and into other parts of the building. For a kitchen in California, keeping that fuel under control is part of the fire risk assessment.
Any of these means the system needs a check-up:
- Cleaning needed before an insurance renewal or survey
- Grease drips onto cooking equipment
- Ductwork thick with old, hardened grease
- Poor airflow at the canopy
School kitchens, at schools like Oak Green School for example, are typically cleaned in the holidays so no lunches are lost.
What your quote should include
- Whether the figure could change on the day
- Whether VAT is included
- If they look at the system before pricing
- Whether inaccessible sections are listed on the report

California kitchens: local notes
Food Standards Agency records list about 92 restaurants, cafés and works canteens and about 57 sandwich bars and takeaways in California and the streets around it, up to about 1.5 miles out. Every kitchen in that count with a canopy has a full extract system, canopy to discharge, to keep clear of grease. California sits within the area of Buckinghamshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. It’s Buckinghamshire council that sends environmental health officers to food businesses in California. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
Commuter trade near Aylesbury station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Church and community hall kitchens, near Church of St Mary or anywhere around California, are easy to forget, but their extracts collect grease like any other.
