In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Day-to-day cleaning is something your team can do: 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, and that’s where we come in.
TR19 inspection for kitchens and businesses in Chorleywood
If you’ve taken over a kitchen in Chorleywood and do not know when the extract was last cleaned, an inspection is the place to start. You get readings, pictures and a clear view of what’s needed, before any cleaning is booked. If you have insurers asking for TR19 evidence and pre-clean surveys before a first TR19 clean, we can help, from wet film thickness tests, insurer audits and pre-clean surveys onwards.
In a smaller place like Chorleywood, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What TR19 inspection looks like in Chorleywood
The FSA’s food hygiene register includes about 12 pubs, bars and clubs within 1.5 miles or so of the middle of Chorleywood. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Chorleywood sits within the area of Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. In Chorleywood, food businesses are inspected by environmental health officers from Three Rivers council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after photos from each clean are a simple way to show the extract is in hand.
Volunteers running a hall kitchen near Christ Church, or anywhere in Chorleywood, may not know when the extract was last cleaned, and a grease test settles it. Bursars and site managers at schools such as Christ Church Chorleywood CofE School tend to book extract cleaning for when the kitchen is empty. Commuter trade near Chorleywood station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

Different parts, different methods
Extract fan and discharge
The discharge at the end of the system is checked as well, since grease reaches the very end of the system.
Horizontal duct runs
Flat duct runs collect grease along their base. We test at points along the run through access panels.
Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
Facilities teams in offices, schools and healthcare sites book us too in Chorleywood and across Hertfordshire. Larger estates can be phased building by building around the people who use them.

How we price TR19 inspection
Before we fix a price, we need to know a few things. We look at:
- Whether several sites go on one quote
- When the work can happen, such as evenings, overnight or weekends
- Site rules, permits and inductions
- The condition of the system
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- A few general shots of the system
- When the site is open and when it’s quiet
- Problems your staff have spotted
- Any previous report or certificate
To help us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Then phone us on 0345 646 2711, or send details by email.
Why it’s worth doing now in Chorleywood
Surveying first means the clean goes to plan. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, so the clean covers the whole system. Light use slows the build-up but doesn’t stop it.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
