Do you need TR19 inspection in Chiswell Green?
Grease in a duct is flammable fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Knowing how much there is lets you act before it becomes a hazard.
If you notice any of these, it’s worth a diagnosis:
- Parts of the system left out of past cleans
- Kitchen extract systems with no recent grease readings
- Insurers asking for TR19 evidence
- Extracts that may be over the 200 micron mean
School kitchens, at schools like Killigrew Primary and Nursery School for example, are normally cleaned in the holidays so no lunches are lost.
Questions to ask before booking
- What paperwork you get at the end
- What’s included in the scope, part by part
- When they can work, and whether that’s outside your opening hours
- Whether a survey comes first
TR19 inspection for kitchens and businesses in Chiswell Green
A pre-clean survey looks at the whole system, from canopy to discharge. Access is checked along the full length, and record grease readings at set points. Common call-outs are for pre-clean surveys before a first TR19 clean and an insurer’s request for a TR19 audit, on wet film thickness tests, pre-clean surveys and post-clean checks.
Kitchens around a place like Chiswell Green are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Keeping the system healthy
After the visit, a few habits help the work last:
- Send TR19 audit reports to your insurer on request
- Book the next test on the date in the report
- Keep canopy edges and gutters wiped down
- Look out for grease drips round the canopy edge
After the inspection, we send a report showing each reading, its location and photos. Keep it with your fire safety and TR19 records.
Regular grease readings keep the cleaning interval honest. It spots changes in how fast grease builds.

What affects the cost of TR19 inspection
The diagnosis comes before the price. The main factors are:
- Whether it’s a one-off visit or part of a schedule
- What state the system is in
- The size of the system
- Working hours and out-of-hours timing
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.
Asking for a quote
To speed up the quote, send us:
- Any access panels or hatches you can see
- The postcode and the type of business
- A few general shots of the system
- Your opening hours and when the area is out of use
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Managing agents and facilities teams in Chiswell Green
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
What a clean won’t put right
Some problems need a different service or another trade:
- Ductwork that was designed or installed badly
- The responsible person’s own fire risk assessment
- Hidden runs that need access panels first
If you’re not sure, just ring 0345 646 2711, or send details by email and we will give you a straight answer before you book.
Where we work
- Pre-clean surveys
- Insurer audits
- Wet film thickness tests
- Access surveys
- Post-clean checks
- Deposit thickness tests
The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, which takes a couple of hours for a typical kitchen extract system. In a place like Chiswell Green, we fit the visit around your hours.
- We go through any past certificates and reports.
- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- We measure the grease and photograph each point.
- We report back with readings and a fixed quote.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use
- Tell us where we can park and unload
Getting a quote
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.

Your questions about TR19 inspection in Chiswell Green
Who inspects food businesses in Chiswell Green?
That’s St Albans City council, whose environmental health officers carry out food hygiene inspections in Chiswell Green. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Who is the fire and rescue service for Chiswell Green?
That is 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.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it doesn’t spread.
What information do you need?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.
What happens on a pre-clean survey?
It’s a look at the whole extract before it’s cleaned, with readings and photos. We can work from pictures and details, or visit, whichever suits the system.
Is TR19 a legal requirement?
No. It’s the benchmark rather than the law. Without TR19 records, an insurance claim can be reduced or refused, so it matters in practice.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
